- Significant feature additions
- API endpoint changes
- Integration additions
**Link format:** `../../docs/[category]/[specific_doc]`
**Common doc paths:**
- `../../docs/providers/[provider]` - Provider-specific docs
- `../../docs/image_generation` - Image generation
- `../../docs/video_generation` - Video generation (if exists)
- `../../docs/response_api` - Responses API
- `../../docs/proxy/logging` - Logging integrations
- `../../docs/proxy/guardrails` - Guardrails
- `../../docs/pass_through/[provider]` - Passthrough endpoints
### 5. Model Table Generation
From git diff analysis, create tables like:
```markdown
| Provider | Model | Context Window | Input ($/1M tokens) | Output ($/1M tokens) | Features |
| -------- | ----- | -------------- | ------------------- | -------------------- | -------- |
| OpenRouter | `openrouter/openai/gpt-4.1` | 1M | $2.00 | $8.00 | Chat completions with vision |
```
**Extract from JSON:**
- `max_input_tokens` → Context Window
- `input_cost_per_token` × 1,000,000 → Input cost
- `output_cost_per_token` × 1,000,000 → Output cost
- `supports_*` fields → Features
- Special pricing fields (per image, per second) for generation models
### 6. PR Categorization Logic
**By Keywords in PR Title:**
- `[Perf]`, `Performance`, `RPS` → Performance Improvements
- `[Bug]`, `[Bug Fix]`, `Fix` → Bug Fixes section
- `[Feat]`, `[Feature]`, `Add support` → Features section
- `[Docs]` → Documentation Updates section
- Provider names (Gemini, OpenAI, etc.) → Group under provider
- `MCP`, `oauth`, `Model Context Protocol` → MCP Gateway
- `service_tier`, `priority`, `cost tracking` → Spend Tracking, Budgets and Rate Limiting
**By PR Content Analysis:**
- New model additions → New Models section
- UI changes → Management Endpoints/UI
- Logging/observability → Logging/Guardrail/Prompt Management Integrations
- Rate limiting/budgets → Spend Tracking, Budgets and Rate Limiting
- Authentication → Management Endpoints/UI
- MCP-related changes → MCP Gateway
- Documentation updates → Documentation Updates
- Performance/memory fixes → Performance/Loadbalancing/Reliability improvements
**Special Categorization Rules:**
- **Service tier pricing** (OpenAI priority/flex) → Spend Tracking section (NOT provider features)
- **Cost breakdown in logging** → Spend Tracking section
- **MCP configuration/OAuth** → MCP Gateway (NOT General Proxy Improvements)
- **All documentation PRs** → Documentation Updates section for visibility
### 7. Writing Style Guidelines
**Tone:**
- Professional but accessible
- Focus on user impact
- Highlight breaking changes clearly
- Use active voice
**Formatting:**
- Use consistent markdown formatting
- Include PR links: `[PR #XXXXX](https://github.com/BerriAI/litellm/pull/XXXXX)`
- Use code blocks for configuration examples
- Bold important terms and section headers
**Warnings/Notes:**
- Add warning boxes for breaking changes
- Include migration instructions when needed
- Provide override options for default changes
### 8. Quality Checks
**Before finalizing:**
- Verify all PR links work
- Check documentation links are valid
- Ensure model pricing is accurate
- Confirm provider names are consistent
- Review for typos and formatting issues
- **Count PRs by section** - Provide final count like:
```
## MM/DD/YYYY
* New Models / Updated Models: XX
* LLM API Endpoints: XX
* Management Endpoints / UI: XX
* Logging / Guardrail / Prompt Management Integrations: XX
* Spend Tracking, Budgets and Rate Limiting: XX
* MCP Gateway: XX
* Performance / Loadbalancing / Reliability improvements: XX
* Documentation Updates: XX
```
### 9. Common Patterns to Follow

# Shared Session Support
## Overview
LiteLLM now supports sharing `aiohttp.ClientSession` instances across multiple API calls to avoid creating unnecessary new sessions. This improves performance and resource utilization.
## Usage
### Basic Usage
```python
import asyncio
from aiohttp import ClientSession
from litellm import acompletion
async def main():
# Create a shared session
async with ClientSession() as shared_session:
# Use the same session for multiple calls
response1 = await acompletion(
model="gpt-4o",
messages=[{"role": "user", "content": "Hello"}],
shared_session=shared_session
)
response2 = await acompletion(
model="gpt-4o",
messages=[{"role": "user", "content": "How are you?"}],
shared_session=shared_session
)
# Both calls reuse the same session!
asyncio.run(main())
```
### Without Shared Session (Default)
```python
import asyncio
from litellm import acompletion
async def main():
# Each call creates a new session
response1 = await acompletion(
model="gpt-4o",
messages=[{"role": "user", "content": "Hello"}]
)
response2 = await acompletion(
model="gpt-4o",
messages=[{"role": "user", "content": "How are you?"}]
)
# Two separate sessions created
asyncio.run(main())
```
## Benefits
- **Performance**: Reuse HTTP connections across multiple calls
- **Resource Efficiency**: Reduce memory and connection overhead
- **Better Control**: Manage session lifecycle explicitly
- **Debugging**: Easy to trace which calls use which sessions
## Debug Logging
Enable debug logging to see session reuse in action:
```python
import os
import litellm
# Enable debug logging
os.environ['LITELLM_LOG'] = 'DEBUG'
# You'll see logs like:
# 🔄 SHARED SESSION: acompletion called with shared_session (ID: 12345)
# ✅ SHARED SESSION: Reusing existing ClientSession (ID: 12345)
```
## Common Patterns
### FastAPI Integration
```python
from fastapi import FastAPI
import aiohttp
import litellm
app = FastAPI()
@app.post("/chat")
async def chat(messages: list[dict]):
# Create session per request
async with aiohttp.ClientSession() as session:
return await litellm.acompletion(
model="gpt-4o",
messages=messages,
shared_session=session
)
```
### Batch Processing
```python
import asyncio
from aiohttp import ClientSession
from litellm import acompletion
async def process_batch(messages_list):
async with ClientSession() as shared_session:
tasks = []
for messages in messages_list:
task = acompletion(
model="gpt-4o",
messages=messages,
shared_session=shared_session
)
tasks.append(task)
# All tasks use the same session
results = await asyncio.gather(*tasks)
return results
```
### Custom Session Configuration
```python
import aiohttp
import litellm
# Create optimized session
async with aiohttp.ClientSession(
timeout=aiohttp.ClientTimeout(total=180),
connector=aiohttp.TCPConnector(limit=300, limit_per_host=75)
) as shared_session:
response = await litellm.acompletion(
model="gpt-4o",
messages=[{"role": "user", "content": "Hello"}],
shared_session=shared_session
)
```
## Implementation Details
The `shared_session` parameter is threaded through the entire LiteLLM call chain:
1. **`acompletion()`** - Accepts `shared_session` parameter
2. **`BaseLLMHTTPHandler`** - Passes session to HTTP client creation
3. **`AsyncHTTPHandler`** - Uses existing session if provided
4. **`LiteLLMAiohttpTransport`** - Reuses the session for HTTP requests
## Backward Compatibility
- **100% backward compatible** - Existing code works unchanged
- **Optional parameter** - `shared_session=None` by default
- **No breaking changes** - All existing functionality preserved
## Testing
Test the shared session functionality:
```python

## Files Modified
The shared session functionality was added to these files:
- `litellm/main.py` - Added `shared_session` parameter to `acompletion()` and `completion()`
- `litellm/llms/custom_httpx/http_handler.py` - Core session reuse logic
- `litellm/llms/custom_httpx/llm_http_handler.py` - HTTP handler integration
- `litellm/llms/openai/openai.py` - OpenAI provider integration
- `litellm/llms/openai/common_utils.py` - OpenAI client creation
- `litellm/llms/azure/chat/o_series_handler.py` - Azure O Series handler
## Troubleshooting
### Session Not Being Reused
1. **Check debug logs**: Enable `LITELLM_LOG=DEBUG` to see session reuse messages
2. **Verify session is not closed**: Ensure the session is still active when making calls
3. **Check parameter passing**: Make sure `shared_session` is passed to all `acompletion()` calls
### Performance Issues
1. **Session configuration**: Tune `aiohttp.ClientSession` parameters for your use case
2. **Connection limits**: Adjust `limit` and `limit_per_host` in `TCPConnector`
3. **Timeout settings**: Configure appropriate timeouts for your environment

# Web Fetch
The web fetch tool allows LLMs to retrieve full content from specified web pages and PDF documents. This enables AI models to access real-time information from the internet and incorporate web content into their responses.
## Web Fetch vs Web Search
**Web Fetch** retrieves the full content from specific web pages that you provide URLs for, while **Web Search** performs internet searches to find relevant information based on your queries.
| Feature | Web Fetch | Web Search |
|---------|-----------|------------|
| **Purpose** | Retrieve content from specific URLs | Search the internet for information |
| **Input** | You provide exact URLs to fetch | You provide search queries/questions |
| **Output** | Full page content from specified URLs | Search results with relevant information |
| **Use Cases** | - Analyzing specific articles<br/>- Comparing content from known websites<br/>- Extracting data from particular pages | - Finding current news/events<br/>- Researching topics<br/>- Getting real-time information |
**Example Web Fetch**: "Fetch the content from https://example.com/pricing and summarize it"
**Example Web Search**: "What are the latest AI developments this week?"
**Supported Providers:**
- Anthropic API (`anthropic/`)
**Supported Tool Types:**
- `web_fetch_20250910` - Web content retrieval tool with usage limits, domain filtering, and citation support
## Quick Start
### LiteLLM Python SDK
```python
import os
from litellm import completion
os.environ["ANTHROPIC_API_KEY"] = "your-api-key"
# Web fetch tool
tools = [
{
"type": "web_fetch_20250910",
"name": "web_fetch",
"max_uses": 5,
}
]
messages = [
{
"role": "user",
"content": "Please analyze the content at https://example.com/article and summarize the main points"
}
]
response = completion(
model="anthropic/claude-3-5-sonnet-latest",
messages=messages,
tools=tools,
)
print(response)
```
### LiteLLM Proxy
1. Define web fetch models on config.yaml
```yaml
model_list:
- model_name: claude-3-5-sonnet-latest # Anthropic claude-3-5-sonnet-latest
litellm_params:
model: anthropic/claude-3-5-sonnet-latest
api_key: os.environ/ANTHROPIC_API_KEY
```
2. Run proxy server
```bash
litellm --config config.yaml
```
3. Test it using the OpenAI Python SDK
```python
import os
from openai import OpenAI
client = OpenAI(
api_key="sk-1234", # your litellm proxy api key
base_url="http://0.0.0.0:4000"
)
response = client.chat.completions.create(
model="claude-3-5-sonnet-latest",
messages=[
{
"role": "user",
"content": "Please fetch and analyze the content from https://news.ycombinator.com and tell me about the top stories"
}
],
tools=[
{
"type": "web_fetch_20250910",
"name": "web_fetch",
"max_uses": 5,
}
]
)
print(response)
```
## Supported Models
Web fetch is available on the following Anthropic API models:
- `claude-opus-4-1-20250805` (Claude Opus 4.1)

# Letta Integration
[Letta](https://github.com/letta-ai/letta) (formerly MemGPT) is a framework for building stateful LLM agents with persistent memory. This guide shows how to integrate both LiteLLM SDK and LiteLLM Proxy with Letta to leverage multiple LLM providers while building memory-enabled agents.
## What is Letta?
Letta allows you to build LLM agents that can:
- Maintain long-term memory across conversations
- Use function calling for tool interactions
- Handle large context windows efficiently
- Persist agent state and memory
## Prerequisites
```bash
pip install letta litellm
```
## Quick Start
<Tabs>
<TabItem value="proxy" label="LiteLLM Proxy">
### 1. Start LiteLLM Proxy
First, create a configuration file for your LiteLLM proxy:
```yaml
# config.yaml
model_list:
- model_name: gpt-4
litellm_params:
model: openai/gpt-4
api_key: os.environ/OPENAI_API_KEY
- model_name: claude-3-sonnet
litellm_params:
model: anthropic/claude-3-sonnet-20240229
api_key: os.environ/ANTHROPIC_API_KEY
- model_name: gpt-3.5-turbo
litellm_params:
model: azure/gpt-35-turbo
api_key: os.environ/AZURE_API_KEY
api_base: os.environ/AZURE_API_BASE
api_version: "2023-07-01-preview"
```
Start the proxy:
```bash
litellm --config config.yaml --port 4000
```
### 2. Configure Letta with LiteLLM Proxy
Configure Letta to use your LiteLLM proxy endpoint:
```python
import letta
from letta import create_client
# Configure Letta to use LiteLLM proxy
client = create_client()
# Configure the LLM endpoint
client.set_default_llm_config(
model="gpt-4", # This should match a model from your LiteLLM config
model_endpoint_type="openai",
model_endpoint="http://localhost:4000", # Your LiteLLM proxy URL
context_window=8192
)
# Configure embedding endpoint (optional)
client.set_default_embedding_config(
embedding_endpoint_type="openai",
embedding_endpoint="http://localhost:4000",
embedding_model="text-embedding-ada-002"
)
```
</TabItem>
<TabItem value="sdk" label="LiteLLM SDK">
### 1. Configure LiteLLM SDK
Set up your API keys and configure LiteLLM:
```python
import os
import litellm
# Set your API keys
os.environ["OPENAI_API_KEY"] = "your-openai-key"
os.environ["ANTHROPIC_API_KEY"] = "your-anthropic-key"
# Optional: Configure default settings
litellm.set_verbose = True # For debugging
```
### 2. Create Custom LLM Wrapper for Letta
Create a custom LLM wrapper that uses LiteLLM SDK:
```python
import letta
from letta import create_client
from letta.llm_api.llm_api_base import LLMConfig
import litellm
from typing import List, Dict, Any
class LiteLLMWrapper:
def __init__(self, model: str):
self.model = model
def chat_completions_create(self, messages: List[Dict], **kwargs):
# Use LiteLLM SDK for completion
response = litellm.completion(
model=self.model,
messages=messages,
**kwargs
)
return response
# Configure Letta with custom LiteLLM wrapper
client = create_client()
# Set up LLM configuration using direct SDK integration
llm_config = LLMConfig(
model="gpt-4", # or "claude-3-sonnet", "azure/gpt-35-turbo", etc.
model_endpoint_type="openai",
context_window=8192
)
client.set_default_llm_config(llm_config)
```
</TabItem>
</Tabs>
### 3. Create and Use a Letta Agent
<Tabs>
<TabItem value="proxy" label="Using LiteLLM Proxy">
```python

<TabItem value="proxy" label="LiteLLM Proxy Authentication">
If your LiteLLM proxy requires authentication:
```python
import os
from letta import LLMConfig
# Set up authenticated configuration
llm_config = LLMConfig(
model="gpt-4",
model_endpoint_type="openai",
model_endpoint="http://localhost:4000",

os.environ["OPENAI_API_KEY"] = "your-litellm-proxy-api-key"
client = create_client()
client.set_default_llm_config(llm_config)
```
For proxy with authentication enabled:
```yaml

```
</TabItem>
<TabItem value="sdk" label="LiteLLM SDK Authentication">
With LiteLLM SDK, set up your provider API keys directly:

## Load Balancing and Fallbacks
<Tabs>
<TabItem value="proxy" label="LiteLLM Proxy Features">
LiteLLM proxy's load balancing and fallback features work seamlessly with Letta:
```yaml

tpm: 80000
rpm: 800
router_settings:
routing_strategy: "usage-based-routing"
fallbacks: [{"gpt-4": ["azure/gpt-4"]}]
```
The proxy handles all routing, load balancing, and fallbacks transparently for Letta.
</TabItem>
<TabItem value="sdk" label="LiteLLM SDK Router">
With LiteLLM SDK, you can set up routing and fallbacks programmatically:
```python

## Best Practices
<Tabs>
<TabItem value="proxy" label="LiteLLM Proxy Best Practices">
1. **Model Selection**: Use appropriate models for different tasks:
- Claude for analysis and reasoning
- GPT-4 for creative tasks
- GPT-3.5-turbo for simple interactions
2. **Proxy Configuration**:
- Set appropriate rate limits and timeouts
- Use fallbacks for reliability
- Enable authentication for production
3. **Memory Management**: Letta handles memory automatically, but monitor usage with large contexts
4. **Cost Optimization**:
- Use the proxy's budgeting features to control costs
- Set up rate limiting per user/team
- Monitor token usage through proxy dashboard
5. **Monitoring**: Enable observability to track agent performance and token usage
</TabItem>
<TabItem value="sdk" label="LiteLLM SDK Best Practices">
1. **Model Selection**: Choose models based on task requirements:
- Use `openai/gpt-4` for complex reasoning
- Use `anthropic/claude-3-sonnet-20240229` for analysis
- Use `openai/gpt-3.5-turbo` for cost-effective simple tasks
2. **Error Handling**: Implement robust error handling with retries:
```python
import litellm
from litellm import completion
# Set up retry logic
litellm.num_retries = 3
litellm.request_timeout = 60
# Custom error handling
def safe_completion(**kwargs):
try:
return completion(**kwargs)
except Exception as e:
print(f"LLM call failed: {e}")
# Implement fallback logic
return completion(model="openai/gpt-3.5-turbo", **kwargs)
```
3. **Cost Management**:
- Use cheaper models for non-critical tasks
- Implement token counting and budgets
- Cache responses when appropriate
4. **Performance**:
- Use async operations for concurrent requests
- Implement connection pooling
- Monitor response times
5. **Security**:
- Store API keys securely (environment variables)
- Rotate keys regularly
- Implement rate limiting

## Troubleshooting
<Tabs>
<TabItem value="proxy" label="LiteLLM Proxy Issues">
### Connection Issues
```bash
# Test your LiteLLM proxy
curl -X POST http://localhost:4000/v1/chat/completions \
-H "Content-Type: application/json" \
-d '{
"model": "gpt-4",
"messages": [{"role": "user", "content": "Hello"}]
}'
```
### Configuration Debugging
```python
# Enable verbose logging
import logging
logging.basicConfig(level=logging.DEBUG)
# Test Letta configuration
client = create_client()
print(client.get_default_llm_config())
```
### Common Proxy Issues
- **Port conflicts**: Make sure port 4000 isn't in use
- **Model not found**: Verify model names match your config.yaml
- **Authentication errors**: Check master key configuration
- **Rate limiting**: Monitor proxy logs for rate limit hits
</TabItem>
<TabItem value="sdk" label="LiteLLM SDK Issues">
### API Key Issues
```python
import os
import litellm
# Check if API keys are set
print("OpenAI Key:", os.environ.get("OPENAI_API_KEY", "Not set"))
print("Anthropic Key:", os.environ.get("ANTHROPIC_API_KEY", "Not set"))
# Test direct LiteLLM call
try:
response = litellm.completion(
model="openai/gpt-3.5-turbo",
messages=[{"role": "user", "content": "Hello"}]
)
print("LiteLLM working:", response.choices[0].message.content)
except Exception as e:
print("LiteLLM error:", e)
```
### Configuration Debugging
```python
# Enable verbose logging
litellm.set_verbose = True
# Test model availability
models = ["openai/gpt-4", "anthropic/claude-3-sonnet-20240229"]
for model in models:
try:
response = litellm.completion(
model=model,
messages=[{"role": "user", "content": "Test"}],
max_tokens=10
)
print(f"✓ {model} working")
except Exception as e:
print(f"✗ {model} failed: {e}")
```
### Common SDK Issues
- **Import errors**: Ensure `pip install litellm letta` is run
- **Model format**: Use `provider/model` format (e.g., `openai/gpt-4`)
- **API key format**: Different providers have different key formats
- **Rate limits**: Implement exponential backoff for retries

## Adding your MCP
### Prerequisites
To store MCP servers in the database, you need to enable database storage:
**Environment Variable:**
```bash
export STORE_MODEL_IN_DB=True
```
**OR in config.yaml:**
```yaml
general_settings:
store_model_in_db: true
```
#### Fine-grained Database Storage Control
By default, when `store_model_in_db` is `true`, all object types (models, MCPs, guardrails, vector stores, etc.) are stored in the database. If you want to store only specific object types, use the `supported_db_objects` setting.
**Example: Store only MCP servers in the database**
```yaml title="config.yaml" showLineNumbers
general_settings:
store_model_in_db: true
supported_db_objects: ["mcp"] # Only store MCP servers in DB
model_list:
- model_name: gpt-4o
litellm_params:
model: openai/gpt-4o
api_key: sk-xxxxxxx
```
**See all available object types:** [Config Settings - supported_db_objects](./proxy/config_settings.md#general_settings---reference)
If `supported_db_objects` is not set, all object types are loaded from the database (default behavior).

}
}
}
}
```
#### How it works when server_url="litellm_proxy"
When server_url="litellm_proxy", LiteLLM bridges non-MCP providers to your MCP tools.
- Tool Discovery: LiteLLM fetches MCP tools and converts them to OpenAI-compatible definitions
- LLM Call: Tools are sent to the LLM with your input; LLM selects which tools to call
- Tool Execution: LiteLLM automatically parses arguments, routes calls to MCP servers, executes tools, and retrieves results
- Response Integration: Tool results are sent back to LLM for final response generation
- Output: Complete response combining LLM reasoning with tool execution results
This enables MCP tool usage with any LiteLLM-supported provider, regardless of native MCP support.
#### Auto-execution for require_approval: "never"
Setting require_approval: "never" triggers automatic tool execution, returning the final response in a single API call without additional user interaction.
### Important Notes
- If you specify both `allowed_tools` and `disallowed_tools`, the allowed list takes priority
- Tool names are case-sensitive

## Forwarding Custom Headers to MCP Servers
LiteLLM supports forwarding additional custom headers from MCP clients to backend MCP servers using the `extra_headers` configuration parameter. This allows you to pass custom authentication tokens, API keys, or other headers that your MCP server requires.
### Configuration
<Tabs>
<TabItem value="config" label="config.yaml">
Configure `extra_headers` in your MCP server configuration to specify which header names should be forwarded:
```yaml title="config.yaml with extra_headers" showLineNumbers
mcp_servers:
github_mcp:
url: "https://api.githubcopilot.com/mcp"
auth_type: "bearer_token"
auth_value: "ghp_default_token"
extra_headers: ["custom_key", "x-custom-header", "Authorization"]
description: "GitHub MCP server with custom header forwarding"
```
</TabItem>
<TabItem value="clientside" label="Dynamically on Client Side">
Use this when giving users access to a [group of MCP servers](#grouping-mcps-access-groups).
**Format:** `x-mcp-{server_alias}-{header_name}: value`
This allows you to use different authentication for different MCP servers.
**Examples:**
- `x-mcp-github-authorization: Bearer ghp_xxxxxxxxx` - GitHub MCP server with Bearer token
- `x-mcp-zapier-x-api-key: sk-xxxxxxxxx` - Zapier MCP server with API key
- `x-mcp-deepwiki-authorization: Basic base64_encoded_creds` - DeepWiki MCP server with Basic auth
```python title="Python Client with Server-Specific Auth" showLineNumbers
from fastmcp import Client
import asyncio
# Standard MCP configuration with multiple servers
config = {
"mcpServers": {
"mcp_group": {
"url": "http://localhost:4000/mcp",
"headers": {
"x-mcp-servers": "dev_group", # assume this gives access to github, zapier and deepwiki
"x-litellm-api-key": "Bearer sk-1234",
"x-mcp-github-authorization": "Bearer gho_token",
"x-mcp-zapier-x-api-key": "sk-xxxxxxxxx",
"x-mcp-deepwiki-authorization": "Basic base64_encoded_creds",
"custom_key": "value"
}
}
}
}
# Create a client that connects to all servers
client = Client(config)
async def main():
async with client:
tools = await client.list_tools()
print(f"Available tools: {tools}")
# call mcp
await client.call_tool(

arguments={'query': 'created:>2024-01-01', 'sort': 'created', 'order': 'desc', 'perPage': 30}
)
if __name__ == "__main__":
asyncio.run(main())
```
**Benefits:**
- **Server-specific authentication**: Each MCP server can use different auth methods
- **Better security**: No need to share the same auth token across all servers
- **Flexible header names**: Support for different auth header types (authorization, x-api-key, etc.)
- **Clean separation**: Each server's auth is clearly identified
</TabItem>
</Tabs>
### Client Usage
When connecting from MCP clients, include the custom headers that match the `extra_headers` configuration:

```
</TabItem>
</Tabs>
### How It Works
1. **Configuration**: Define `extra_headers` in your MCP server config with the header names you want to forward
2. **Client Headers**: Include the corresponding headers in your MCP client requests
3. **Header Forwarding**: LiteLLM automatically forwards matching headers to the backend MCP server
4. **Authentication**: The backend MCP server receives both the configured auth headers and the custom headers
### Use Cases
- **Custom Authentication**: Forward custom API keys or tokens required by specific MCP servers
- **Request Context**: Pass user identification, session data, or request tracking headers
- **Third-party Integration**: Include headers required by external services that your MCP server integrates with
- **Multi-tenant Systems**: Forward tenant-specific headers for proper request routing
### Security Considerations
- Only headers listed in `extra_headers` are forwarded to maintain security
- Sensitive headers should be passed through environment variables when possible
- Consider using server-specific auth headers for better security isolation

## MCP Oauth
LiteLLM v 1.77.6 added support for OAuth 2.0 Client Credentials for MCP servers.
This configuration is currently available on the config.yaml, with UI support coming soon.

## MCP Cost Tracking
LiteLLM provides two ways to track costs for MCP tool calls:
| Method | When to Use | What It Does |
|--------|-------------|--------------|
| **Config-based Cost Tracking** | Simple cost tracking with fixed costs per tool/server | Automatically tracks costs based on configuration |
| **Custom Post-MCP Hook** | Dynamic cost tracking with custom logic | Allows custom cost calculations and response modifications |
### Config-based Cost Tracking
Configure fixed costs for MCP servers directly in your config.yaml:
```yaml title="config.yaml" showLineNumbers
model_list:
- model_name: gpt-4o
litellm_params:
model: openai/gpt-4o
api_key: sk-xxxxxxx
mcp_servers:
zapier_server:
url: "https://actions.zapier.com/mcp/sk-xxxxx/sse"
mcp_info:
mcp_server_cost_info:
# Default cost for all tools in this server
default_cost_per_query: 0.01
# Custom cost for specific tools
tool_name_to_cost_per_query:
send_email: 0.05
create_document: 0.03
expensive_api_server:
url: "https://api.expensive-service.com/mcp"
mcp_info:
mcp_server_cost_info:
default_cost_per_query: 1.50
```
### Custom Post-MCP Hook
Use this when you need dynamic cost calculation or want to modify the MCP response before it's returned to the user.
#### 1. Create a custom MCP hook file
```python title="custom_mcp_hook.py" showLineNumbers
from typing import Optional
from litellm.integrations.custom_logger import CustomLogger
from litellm.types.mcp import MCPPostCallResponseObject
class CustomMCPCostTracker(CustomLogger):
"""
Custom handler for MCP cost tracking and response modification
"""
async def async_post_mcp_tool_call_hook(
self,
kwargs,
response_obj: MCPPostCallResponseObject,
start_time,
end_time
) -> Optional[MCPPostCallResponseObject]:
"""
Called after each MCP tool call.
Modify costs and response before returning to user.
"""
# Extract tool information from kwargs
tool_name = kwargs.get("name", "")
server_name = kwargs.get("server_name", "")
# Calculate custom cost based on your logic
custom_cost = 42.00
# Set the response cost
response_obj.hidden_params.response_cost = custom_cost
return response_obj
# Create instance for LiteLLM to use
custom_mcp_cost_tracker = CustomMCPCostTracker()
```
#### 2. Configure in config.yaml
```yaml title="config.yaml" showLineNumbers
model_list:
- model_name: gpt-4o
litellm_params:
model: openai/gpt-4o
api_key: sk-xxxxxxx
# Add your custom MCP hook
callbacks:
- custom_mcp_hook.custom_mcp_cost_tracker
mcp_servers:
zapier_server:
url: "https://actions.zapier.com/mcp/sk-xxxxx/sse"
```
#### 3. Start the proxy
```shell
$ litellm --config /path/to/config.yaml
```
When MCP tools are called, your custom hook will:
1. Calculate costs based on your custom logic
2. Modify the response if needed
3. Track costs in LiteLLM's logging system
## MCP Guardrails
LiteLLM supports applying guardrails to MCP tool calls to ensure security and compliance. You can configure guardrails to run before or during MCP calls to validate inputs and block or mask sensitive information.
### Supported MCP Guardrail Modes
MCP guardrails support the following modes:
- `pre_mcp_call`: Run **before** MCP call, on **input**. Use this mode when you want to apply validation/masking/blocking for MCP requests
- `during_mcp_call`: Run **during** MCP call execution. Use this mode for real-time monitoring and intervention
### Configuration Examples
Configure guardrails to run before MCP tool calls to validate and sanitize inputs:
```yaml title="config.yaml" showLineNumbers
guardrails:
- guardrail_name: "mcp-input-validation"
litellm_params:
guardrail: presidio # or other supported guardrails
mode: "pre_mcp_call" # or during_mcp_call
pii_entities_config:
CREDIT_CARD: "BLOCK" # Will block requests containing credit card numbers
EMAIL_ADDRESS: "MASK" # Will mask email addresses
PHONE_NUMBER: "MASK" # Will mask phone numbers
default_on: true
```
### Usage Examples
#### Testing Pre-MCP Call Guardrails
Test your MCP guardrails with a request that includes sensitive information:
```bash title="Test MCP Guardrail" showLineNumbers
curl http://localhost:4000/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer sk-1234" \
-d '{
"model": "gpt-3.5-turbo",
"messages": [
{"role": "user", "content": "My credit card is 4111-1111-1111-1111 and my email is john@example.com"}
],
"guardrails": ["mcp-input-validation"]
}'
```
The request will be processed as follows:
1. Credit card number will be blocked (request rejected)
2. Email address will be masked (e.g., replaced with `<EMAIL_ADDRESS>`)
#### Using with MCP Tools
When using MCP tools, guardrails will be applied to the tool inputs:
```python title="Python Example with MCP Guardrails" showLineNumbers
import openai
client = openai.OpenAI(
api_key="your-api-key",
base_url="http://localhost:4000"
)
# This request will trigger MCP guardrails
response = client.chat.completions.create(
model="gpt-3.5-turbo",
messages=[
{"role": "user", "content": "Send an email to 555-123-4567 with my SSN 123-45-6789"}
],
tools=[{"type": "mcp", "server_label": "litellm", "server_url": "litellm_proxy"}],
guardrails=["mcp-input-validation"]
)
```
### Supported Guardrail Providers
MCP guardrails work with all LiteLLM-supported guardrail providers:
- **Presidio**: PII detection and masking
- **Bedrock**: AWS Bedrock guardrails
- **Lakera**: Content moderation
- **Aporia**: Custom guardrails
- **Custom**: Your own guardrail implementations
## MCP Permission Management
LiteLLM supports managing permissions for MCP Servers by Keys, Teams, Organizations (entities) on LiteLLM. When a MCP client attempts to list tools, LiteLLM will only return the tools the entity has permissions to access.
When Creating a Key, Team, or Organization, you can select the allowed MCP Servers that the entity has access to.

# MCP Permission Management
Control which MCP servers and tools can be accessed by specific keys, teams, or organizations in LiteLLM. When a client attempts to list or call tools, LiteLLM enforces access controls based on configured permissions.
## Overview
LiteLLM provides fine-grained permission management for MCP servers, allowing you to:
- **Restrict MCP access by entity**: Control which keys, teams, or organizations can access specific MCP servers
- **Tool-level filtering**: Automatically filter available tools based on entity permissions
- **Centralized control**: Manage all MCP permissions from the LiteLLM Admin UI or API
This ensures that only authorized entities can discover and use MCP tools, providing an additional security layer for your MCP infrastructure.

## Set Allowed Tools for a Key, Team, or Organization
Control which tools different teams can access from the same MCP server. For example, give your Engineering team access to `list_repositories`, `create_issue`, and `search_code`, while Sales only gets `search_code` and `close_issue`.
This video shows how to set allowed tools for a Key, Team, or Organization.

### Use with Cursor IDE
Use tools directly from Cursor IDE with LiteLLM MCP:
**Setup Instructions:**
1. **Open Cursor Settings**: Use `⇧+⌘+J` (Mac) or `Ctrl+Shift+J` (Windows/Linux)
2. **Navigate to MCP Tools**: Go to the "MCP Tools" tab and click "New MCP Server"
3. **Add Configuration**: Copy and paste the JSON configuration below, then save with `Cmd+S` or `Ctrl+S`
```json title="Basic Cursor MCP Configuration" showLineNumbers
{
"mcpServers": {
"LiteLLM": {
"url": "litellm_proxy",
"headers": {
"x-litellm-api-key": "Bearer $LITELLM_API_KEY"
}
}
}
}
```
#### How it works when server_url="litellm_proxy"
When server_url="litellm_proxy", LiteLLM bridges non-MCP providers to your MCP tools.
- Tool Discovery: LiteLLM fetches MCP tools and converts them to OpenAI-compatible definitions
- LLM Call: Tools are sent to the LLM with your input; LLM selects which tools to call
- Tool Execution: LiteLLM automatically parses arguments, routes calls to MCP servers, executes tools, and retrieves results
- Response Integration: Tool results are sent back to LLM for final response generation
- Output: Complete response combining LLM reasoning with tool execution results
This enables MCP tool usage with any LiteLLM-supported provider, regardless of native MCP support.
#### Auto-execution for require_approval: "never"
Setting require_approval: "never" triggers automatic tool execution, returning the final response in a single API call without additional user interaction.

- `async_pre_call_hook` - Modify requests before sending
### Example: Modifying the Response in async_post_call_success_hook
You can use `async_post_call_success_hook` to add custom headers or metadata to the response before it is returned to the client. For example:
```python
async def async_post_call_success_hook(data, user_api_key_dict, response):
# Add a custom header to the response
additional_headers = getattr(response, "_hidden_params", {}).get("additional_headers", {}) or {}
additional_headers["x-litellm-custom-header"] = "my-value"
if not hasattr(response, "_hidden_params"):
response._hidden_params = {}
response._hidden_params["additional_headers"] = additional_headers
return response
```
This allows you to inject custom metadata or headers into the response for downstream consumers. You can use this pattern to pass information to clients, proxies, or observability tools.
## Callback Functions
If you just want to log on a specific event (e.g. on input) - you can use callback functions.

### Session Tracking and Tracing
</TabItem>

## Session Tracking and Tracing
Track multi-step and agentic LLM interactions using session IDs and paths:
```python
litellm.metadata = {
"Helicone-Auth": f"Bearer {os.getenv('HELICONE_API_KEY')}", # Authenticate to send requests to Helicone API
"Helicone-Session-Id": "session-abc-123", # The session ID you want to track
"Helicone-Session-Path": "parent-trace/child-trace", # The path of the session
}
```
- `Helicone-Session-Id`: Use this to specify the unique identifier for the session you want to track. This allows you to group related requests together.
- `Helicone-Session-Path`: This header defines the path of the session, allowing you to represent parent and child traces. For example, "parent/child" represents a child trace of a parent trace.
By using these two headers, you can effectively group and visualize multi-step LLM interactions, gaining insights into complex AI workflows.

# PostHog - Tracking LLM Usage Analytics
## What is PostHog?
PostHog is an open-source product analytics platform that helps you track and analyze how users interact with your product. For LLM applications, PostHog provides specialized AI features to track model usage, performance, and user interactions with your AI features.
## Usage with LiteLLM Proxy (LLM Gateway)
**Step 1**: Create a `config.yaml` file and set `litellm_settings`: `success_callback`
```yaml
model_list:
- model_name: gpt-3.5-turbo
litellm_params:
model: gpt-3.5-turbo
litellm_settings:
success_callback: ["posthog"]
failure_callback: ["posthog"]
```
**Step 2**: Set required environment variables
```shell
export POSTHOG_API_KEY="your-posthog-api-key"
# Optional, defaults to https://app.posthog.com
export POSTHOG_API_URL="https://app.posthog.com" # optional
```
**Step 3**: Start the proxy, make a test request
Start proxy
```shell
litellm --config config.yaml --debug
```
Test Request
```shell
curl --location 'http://0.0.0.0:4000/chat/completions' \
--header 'Content-Type: application/json' \
--data '{
"model": "gpt-3.5-turbo",
"messages": [
{
"role": "user",
"content": "what llm are you"
}
],
"metadata": {
"user_id": "user-123",
"custom_field": "custom_value"
}
}'
```
## Usage with LiteLLM Python SDK
### Quick Start
Use just 2 lines of code, to instantly log your responses **across all providers** with PostHog:
```python
litellm.success_callback = ["posthog"]
litellm.failure_callback = ["posthog"] # logs errors to posthog
```
```python
import litellm
import os
# from PostHog
os.environ["POSTHOG_API_KEY"] = ""
# Optional, defaults to https://app.posthog.com
os.environ["POSTHOG_API_URL"] = "" # optional
# LLM API Keys
os.environ['OPENAI_API_KEY']=""
# set posthog as a callback, litellm will send the data to posthog
litellm.success_callback = ["posthog"]
# openai call
response = litellm.completion(
model="gpt-3.5-turbo",
messages=[
{"role": "user", "content": "Hi - i'm openai"}
],
metadata = {
"user_id": "user-123", # set posthog user ID
}
)
```
### Advanced
#### Set User ID and Custom Metadata
Pass `user_id` in `metadata` to associate events with specific users in PostHog:
**With LiteLLM Python SDK:**
```python
import litellm
litellm.success_callback = ["posthog"]
response = litellm.completion(
model="gpt-3.5-turbo",
messages=[
{"role": "user", "content": "Hello world"}
],
metadata={
"user_id": "user-123", # Add user ID for PostHog tracking
"custom_field": "custom_value" # Add custom metadata
}
)
```
**With LiteLLM Proxy using OpenAI Python SDK:**
```python
import openai
client = openai.OpenAI(
api_key="sk-1234", # Your LiteLLM Proxy API key
base_url="http://0.0.0.0:4000" # Your LiteLLM Proxy URL
)
response = client.chat.completions.create(
model="gpt-3.5-turbo",
messages=[
{"role": "user", "content": "Hello world"}
],
extra_body={
"metadata": {
"user_id": "user-123", # Add user ID for PostHog tracking
"project_name": "my-project", # Add custom metadata
"environment": "production"
}
}
)
```
#### Disable Logging for Specific Calls
Use the `no-log` flag to prevent logging for specific calls:
```python
import litellm
litellm.success_callback = ["posthog"]
response = litellm.completion(
model="gpt-3.5-turbo",
messages=[
{"role": "user", "content": "This won't be logged"}
],
metadata={"no-log": True}
)
```
## What's Logged to PostHog?
When LiteLLM logs to PostHog, it captures detailed information about your LLM usage:
### For Completion Calls
- **Model Information**: Provider, model name, model parameters
- **Usage Metrics**: Input tokens, output tokens, total cost
- **Performance**: Latency, completion time
- **Content**: Input messages, model responses (respects privacy settings)
- **Metadata**: Custom fields, user ID, trace information
### For Embedding Calls
- **Model Information**: Provider, model name
- **Usage Metrics**: Input tokens, total cost
- **Performance**: Latency
- **Content**: Input text (respects privacy settings)
- **Metadata**: Custom fields, user ID, trace information
### For Errors
- **Error Details**: Error type, error message, stack trace
- **Context**: Model, provider, input that caused the error
- **Timing**: When the error occurred, request duration
## Environment Variables
| Variable | Required | Description |
|----------|----------|-------------|
| `POSTHOG_API_KEY` | Yes | Your PostHog project API key |
| `POSTHOG_API_URL` | No | PostHog API URL (defaults to https://app.posthog.com) |
## Troubleshooting
### 1. Missing API Key
```
Error: POSTHOG_API_KEY is not set
```
Set your PostHog API key:
```python
import os
os.environ["POSTHOG_API_KEY"] = "your-api-key"
```
### 2. Custom PostHog Instance
If you're using a self-hosted PostHog instance:
```python
import os
os.environ["POSTHOG_API_URL"] = "https://your-posthog-instance.com"
```
### 3. Events Not Appearing
- Check that your API key is correct
- Verify network connectivity to PostHog
- Events may take a few minutes to appear in PostHog dashboard

# Azure Passthrough
Pass-through endpoints for `/azure`
## Overview
| Feature | Supported | Notes |
|-------|-------|-------|
| Cost Tracking | ❌ | Not supported |
| Logging | ✅ | Works across all integrations |
| Streaming | ✅ | Fully supported |
### When to use this?
- For most use cases, you should use the [native LiteLLM Azure OpenAI Integration](../providers/azure/azure) (`/chat/completions`, `/embeddings`, `/completions`, `/images`, etc.)
- Use this passthrough to call newer or less common Azure OpenAI endpoints that LiteLLM doesn't fully support yet, such as `/assistants`, `/threads`, `/vector_stores`
Simply replace your Azure endpoint (e.g. `https://<your-resource-name>.openai.azure.com`) with `LITELLM_PROXY_BASE_URL/azure`
## Usage Examples
### Assistants API
#### Create Azure OpenAI Client
Make sure you do the following:
- Point `azure_endpoint` to your `LITELLM_PROXY_BASE_URL/azure`
- Use your `LITELLM_API_KEY` as the `api_key`
```python
import openai
client = openai.AzureOpenAI(
azure_endpoint="http://0.0.0.0:4000/azure", # <your-proxy-url>/azure
api_key="sk-anything", # <your-proxy-api-key>

## Vertex AI Live API WebSocket
LiteLLM can now proxy the Vertex AI Live API to help you experiment with streaming audio/text from Gemini Live models without exposing Google credentials to clients.
- Configure default Vertex credentials via `default_vertex_config` or environment variables (see examples above).
- Connect to `wss://<PROXY_URL>/vertex_ai/live`. LiteLLM will exchange your saved credentials for a short-lived access token and forward messages bidirectionally.
- Optional query params `vertex_project`, `vertex_location`, and `model` let you override defaults for multi-project setups or global-only models.

# Vertex AI Live API WebSocket Passthrough
LiteLLM now supports WebSocket passthrough for the Vertex AI Live API, enabling real-time bidirectional communication with Gemini models.
## Overview
The Vertex AI Live API WebSocket passthrough allows you to:
- Connect to Vertex AI Live API through LiteLLM proxy
- Use existing Vertex AI authentication methods
- Pass through all WebSocket messages bidirectionally
- Support text, audio, video, and multimodal interactions
- Track costs automatically for all usage types
## Configuration
### Environment Variables
Set the following environment variables for Vertex AI authentication:
```bash
# Required
DEFAULT_VERTEXAI_PROJECT=your-project-id
DEFAULT_VERTEXAI_LOCATION=us-central1
# Optional - use one of these for authentication
DEFAULT_GOOGLE_APPLICATION_CREDENTIALS=/path/to/service-account.json
# OR run: gcloud auth application-default login
```
### Configuration File
Alternatively, configure in your `config.yaml`:
```yaml
litellm_settings:
default_vertex_config:
vertex_project: "your-project-id"
vertex_location: "us-central1"
vertex_credentials: "os.environ/GOOGLE_APPLICATION_CREDENTIALS"
```
## Usage
### WebSocket Endpoints
- `ws://your-proxy-host/v1/vertex-ai/live`
- `ws://your-proxy-host/vertex-ai/live`
### Query Parameters
- `project_id` (optional): Google Cloud project ID (can be set in config)
- `location` (optional): Vertex AI location (can be set in config, default: us-central1)
### Example Connection
```javascript
// If project_id and location are set in config, you can connect without query params
const ws = new WebSocket('ws://localhost:4000/v1/vertex-ai/live');
// Or specify them explicitly
const ws = new WebSocket('ws://localhost:4000/v1/vertex-ai/live?project_id=your-project-id&location=us-central1');
```
## Cost Tracking
The WebSocket passthrough automatically tracks costs for all usage types based on the [Vertex AI pricing](https://cloud.google.com/vertex-ai/generative-ai/pricing#model-optimizer-pricing):
### Supported Cost Tracking
- **Text**: Character-based or token-based pricing depending on model
- **Audio**: Per-second pricing for audio input/output
- **Video**: Per-second pricing for video input
- **Images**: Per-image pricing for image input
### Cost Calculation
Costs are calculated using the same methods as other Vertex AI models in LiteLLM:
- Uses `cost_per_character` for Gemini models
- Uses `cost_per_token` for partner models (Claude, Llama, etc.)
- Includes audio, video, and image costs when applicable
### Cost Logging
Costs are automatically logged to:
- LiteLLM proxy logs
- Database (if configured)
- Spend tracking system
- Admin dashboard
Example log output:
```
Vertex AI Live WebSocket session cost: $0.001234 (input: $0.000800, output: $0.000434) tokens: 150, characters: 1200, duration: 45.2s
```
## API Reference
### Setup Message
Send this message first to initialize the session:
```json
{
"setup": {
"model": "projects/your-project-id/locations/us-central1/publishers/google/models/gemini-2.0-flash-live-preview-04-09",
"generation_config": {
"response_modalities": ["TEXT"]
}
}
}
```
### Text Input
```json
{
"client_content": {
"turns": [
{
"role": "user",
"parts": [{"text": "Hello! How are you?"}]
}
],
"turn_complete": true
}
}
```
### Audio Input
```json
{
"realtime_input": {
"media_chunks": [
{
"data": "base64-encoded-audio-data",
"mime_type": "audio/pcm"
}
]
}
}
```
## Supported Features
### Response Modalities
- **TEXT**: Text responses
- **AUDIO**: Audio responses with voice synthesis
### Tools
- **Function Calling**: Define and use custom functions
- **Code Execution**: Execute Python code
- **Google Search**: Search the web
- **Voice Activity Detection**: Detect when user is speaking
### Advanced Features
- **Audio Transcription**: Transcribe input and output audio
- **Proactive Audio**: Model responds only when relevant
- **Affective Dialog**: Understand emotional expressions
## Examples
### Python Client
```python
import asyncio
import json
import websockets
async def chat_with_gemini():
uri = "ws://localhost:4000/v1/vertex-ai/live?project_id=your-project-id"
async with websockets.connect(uri) as websocket:
# Setup
setup = {
"setup": {
"model": "projects/your-project-id/locations/us-central1/publishers/google/models/gemini-2.0-flash-live-preview-04-09",
"generation_config": {"response_modalities": ["TEXT"]}
}
}
await websocket.send(json.dumps(setup))
# Wait for setup response
response = await websocket.recv()
print(f"Setup: {response}")
# Send message
message = {
"client_content": {
"turns": [{"role": "user", "parts": [{"text": "Hello!"}]}],
"turn_complete": True
}
}
await websocket.send(json.dumps(message))
# Receive response
async for response in websocket:
print(f"Response: {response}")
# Check if turn is complete
data = json.loads(response)
if data.get("serverContent", {}).get("turnComplete"):
break
asyncio.run(chat_with_gemini())
```
### JavaScript Client
```javascript
const ws = new WebSocket('ws://localhost:4000/v1/vertex-ai/live?project_id=your-project-id');
ws.onopen = function() {
// Send setup
const setup = {
setup: {
model: "projects/your-project-id/locations/us-central1/publishers/google/models/gemini-2.0-flash-live-preview-04-09",
generation_config: { response_modalities: ["TEXT"] }
}
};
ws.send(JSON.stringify(setup));
};
ws.onmessage = function(event) {
const data = JSON.parse(event.data);
console.log('Received:', data);
// Check if setup is complete
if (data.setupComplete) {
// Send a message
const message = {
client_content: {
turns: [{ role: "user", parts: [{ text: "Hello!" }] }],
turn_complete: true
}
};
ws.send(JSON.stringify(message));
}
};
```
## Error Handling
The WebSocket connection may close with these codes:
- `4001`: Vertex AI credentials not configured
- `4002`: Project ID not provided
- `1011`: Internal server error
## Authentication
The WebSocket passthrough uses the same authentication as other LiteLLM endpoints:
1. **API Key**: Pass `Authorization: Bearer your-api-key` header
2. **Vertex AI Credentials**: Set environment variables or config file
## Limitations
- Requires valid Google Cloud project with Vertex AI API enabled
- WebSocket connections are not persistent across server restarts
- Rate limits apply based on your Google Cloud quotas
## Troubleshooting
### Common Issues
1. **Authentication Error**: Ensure Vertex AI credentials are properly configured
2. **Project Not Found**: Verify the project ID exists and has Vertex AI enabled
3. **Connection Refused**: Check that the LiteLLM proxy server is running
### Debug Mode
Enable debug logging to see detailed connection information:
```bash
export LITELLM_LOG=DEBUG
```

Example of using [Bedrock Guardrails with LiteLLM](https://docs.aws.amazon.com/bedrock/latest/userguide/guardrails-use-converse-api.html)
### Selective Content Moderation with `guarded_text`
LiteLLM supports selective content moderation using the `guarded_text` content type. This allows you to wrap only specific content that should be moderated by Bedrock Guardrails, rather than evaluating the entire conversation.
**How it works:**
- Content with `type: "guarded_text"` gets automatically wrapped in `guardrailConverseContent` blocks
- Only the wrapped content is evaluated by Bedrock Guardrails
- Regular content with `type: "text"` bypasses guardrail evaluation
:::note
If `guarded_text` is not used, the entire conversation history will be sent to the guardrail for evaluation, which can increase latency and costs.

### Required AWS IAM Policy for AssumeRole
To use `aws_role_name` (STS AssumeRole) with LiteLLM, your IAM user or role **must** have permission to call `sts:AssumeRole` on the target role. If you see an error like:
```
An error occurred (AccessDenied) when calling the AssumeRole operation: User: arn:aws:sts::...:assumed-role/litellm-ecs-task-role/... is not authorized to perform: sts:AssumeRole on resource: arn:aws:iam::...:role/Enterprise/BedrockCrossAccountConsumer
```
This means the IAM identity running LiteLLM does **not** have permission to assume the target role. You must update your IAM policy to allow this action.
#### Example IAM Policy
Replace `<TARGET_ROLE_ARN>` with the ARN of the role you want to assume (e.g., `arn:aws:iam::123456789012:role/Enterprise/BedrockCrossAccountConsumer`).
```json
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": "sts:AssumeRole",
"Resource": "<TARGET_ROLE_ARN>"
}
]
}
```
**Note:** The target role itself must also trust the calling IAM identity (via its trust policy) for AssumeRole to succeed. See [AWS AssumeRole docs](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-api.html) for more details.

# Bedrock Embedding
## Supported Embedding Models
| Provider | LiteLLM Route | AWS Documentation |
|----------|---------------|-------------------|
| Amazon Titan | `bedrock/amazon.*` | [Amazon Titan Embeddings](https://docs.aws.amazon.com/bedrock/latest/userguide/titan-embedding-models.html) |
| Cohere | `bedrock/cohere.*` | [Cohere Embeddings](https://docs.aws.amazon.com/bedrock/latest/userguide/model-parameters-cohere-embed.html) |
| TwelveLabs | `bedrock/us.twelvelabs.*` | [TwelveLabs](https://docs.aws.amazon.com/bedrock/latest/userguide/model-parameters-twelvelabs.html) |
## Async Invoke Support
LiteLLM supports AWS Bedrock's async-invoke feature for embedding models that require asynchronous processing, particularly useful for large media files (video, audio) or when you need to process embeddings in the background.
### Supported Models
| Provider | Async Invoke Route | Use Case |
|----------|-------------------|----------|
| TwelveLabs Marengo | `bedrock/async_invoke/us.twelvelabs.marengo-embed-2-7-v1:0` | Video, audio, image, and text embeddings |
### Required Parameters
When using async-invoke, you must provide:
| Parameter | Description | Required |
|-----------|-------------|----------|
| `output_s3_uri` | S3 URI where the embedding results will be stored | ✅ Yes |
| `input_type` | Type of input: `"text"`, `"image"`, `"video"`, or `"audio"` | ✅ Yes |
| `aws_region_name` | AWS region for the request | ✅ Yes |
### Usage
#### Basic Async Invoke
```python
from litellm import embedding
# Text embedding with async-invoke
response = embedding(
model="bedrock/async_invoke/us.twelvelabs.marengo-embed-2-7-v1:0",
input=["Hello world from LiteLLM async invoke!"],
aws_region_name="us-east-1",
input_type="text",
output_s3_uri="s3://your-bucket/async-invoke-output/"
)
print(f"Job submitted! Invocation ARN: {response._hidden_params._invocation_arn}")
```
#### Video/Audio Embedding
```python
# Video embedding (requires async-invoke)
response = embedding(
model="bedrock/async_invoke/us.twelvelabs.marengo-embed-2-7-v1:0",
input=["s3://your-bucket/video.mp4"], # S3 URL for video
aws_region_name="us-east-1",
input_type="video",
output_s3_uri="s3://your-bucket/async-invoke-output/"
)
print(f"Video embedding job submitted! ARN: {response._hidden_params._invocation_arn}")
```
#### Image Embedding with Base64
```python
import base64
# Load and encode image
with open("image.jpg", "rb") as img_file:
img_data = base64.b64encode(img_file.read()).decode('utf-8')
img_base64 = f"data:image/jpeg;base64,{img_data}"
response = embedding(
model="bedrock/async_invoke/us.twelvelabs.marengo-embed-2-7-v1:0",
input=[img_base64],
aws_region_name="us-east-1",
input_type="image",
output_s3_uri="s3://your-bucket/async-invoke-output/"
)
```
### Retrieving Job Information
#### Getting Job ID and Invocation ARN
The async-invoke response includes the invocation ARN in the hidden parameters:
```python
response = embedding(
model="bedrock/async_invoke/us.twelvelabs.marengo-embed-2-7-v1:0",
input=["Hello world"],
aws_region_name="us-east-1",
input_type="text",
output_s3_uri="s3://your-bucket/async-invoke-output/"
)
# Access invocation ARN
invocation_arn = response._hidden_params._invocation_arn
print(f"Invocation ARN: {invocation_arn}")
# Extract job ID from ARN (last part after the last slash)
job_id = invocation_arn.split("/")[-1]
print(f"Job ID: {job_id}")
```
#### Checking Job Status
Use LiteLLM's `retrieve_batch` function to check if your job is still processing:
```python
from litellm import retrieve_batch
def check_async_job_status(invocation_arn, aws_region_name="us-east-1"):
"""Check the status of an async invoke job using LiteLLM batch API"""
try:
response = retrieve_batch(
batch_id=invocation_arn,
custom_llm_provider="bedrock",
aws_region_name=aws_region_name
)
return response
except Exception as e:
print(f"Error checking job status: {e}")
return None
# Check status
status = check_async_job_status(invocation_arn, "us-east-1")
if status:
print(f"Job Status: {status.status}")
print(f"Output Location: {status.output_file_id}")
```
**Note:** The actual embedding results are stored in S3. The `output_file_id` from the batch status can be used to locate the results file in your S3 bucket.
### Error Handling
#### Common Errors
| Error | Cause | Solution |
|-------|-------|----------|
| `ValueError: output_s3_uri cannot be empty` | Missing S3 output URI | Provide a valid S3 URI |
| `ValueError: Input type 'video' requires async_invoke route` | Using video/audio without async-invoke | Use `bedrock/async_invoke/` model prefix |
| `ValueError: input_type is required` | Missing input type parameter | Specify `input_type` parameter |
#### Example Error Handling
```python
try:
response = embedding(
model="bedrock/async_invoke/us.twelvelabs.marengo-embed-2-7-v1:0",
input=["Hello world"],
aws_region_name="us-east-1",
input_type="text",
output_s3_uri="s3://your-bucket/output/" # Required for async-invoke
)
print("Job submitted successfully!")
except ValueError as e:
if "output_s3_uri cannot be empty" in str(e):
print("Error: Please provide a valid S3 output URI")
elif "requires async_invoke route" in str(e):
print("Error: Use async_invoke model for video/audio inputs")
else:
print(f"Error: {e}")
except Exception as e:
print(f"Unexpected error: {e}")
```
### Best Practices
1. **Use async-invoke for large files**: Video and audio files are better processed asynchronously
2. **Use LiteLLM batch API**: Use `retrieve_batch()` instead of direct Bedrock API calls for status checking
3. **Monitor job status**: Check job status periodically using the batch API to know when results are ready
4. **Handle errors gracefully**: Implement proper error handling for network issues and job failures
5. **Set appropriate timeouts**: Consider the processing time for large files
6. **Use S3 for large inputs**: For video/audio, use S3 URLs instead of base64 encoding
### Limitations
- Async-invoke is currently only supported for TwelveLabs Marengo models
- Results are stored in S3 and must be retrieved separately using the output file ID
- Job status checking requires using LiteLLM's `retrieve_batch()` function
- No built-in polling mechanism in LiteLLM (must implement your own status checking loop)
### API keys
This can be set as env variables or passed as **params to litellm.embedding()**
```python
import os
os.environ["AWS_ACCESS_KEY_ID"] = "" # Access key
os.environ["AWS_SECRET_ACCESS_KEY"] = "" # Secret access key
os.environ["AWS_REGION_NAME"] = "" # us-east-1, us-east-2, us-west-1, us-west-2
```
## Usage
### LiteLLM Python SDK
```python
from litellm import embedding
response = embedding(
model="bedrock/amazon.titan-embed-text-v1",
input=["good morning from litellm"],
)
print(response)
```
### LiteLLM Proxy Server
#### 1. Setup config.yaml
```yaml
model_list:
- model_name: titan-embed-v1
litellm_params:
model: bedrock/amazon.titan-embed-text-v1
aws_access_key_id: os.environ/AWS_ACCESS_KEY_ID
aws_secret_access_key: os.environ/AWS_SECRET_ACCESS_KEY
aws_region_name: us-east-1
- model_name: titan-embed-v2
litellm_params:
model: bedrock/amazon.titan-embed-text-v2:0
aws_access_key_id: os.environ/AWS_ACCESS_KEY_ID
aws_secret_access_key: os.environ/AWS_SECRET_ACCESS_KEY
aws_region_name: us-east-1
```
#### 2. Start Proxy
```bash
litellm --config /path/to/config.yaml
```
#### 3. Use with OpenAI Python SDK
```python
import openai
client = openai.OpenAI(
api_key="anything",
base_url="http://0.0.0.0:4000"
)
response = client.embeddings.create(
input=["good morning from litellm"],
model="titan-embed-v1"
)
print(response)
```
#### 4. Use with LiteLLM Python SDK
```python
import litellm
response = litellm.embedding(
model="titan-embed-v1", # model alias from config.yaml
input=["good morning from litellm"],
api_base="http://0.0.0.0:4000",
api_key="anything"
)
print(response)
```

## Usage
<Tabs>
<TabItem value="sdk" label="SDK">
```python
from litellm import completion
import os
# Optional: Set custom API base. Useful if your lemonade server is on
# a different port
os.environ['LEMONADE_API_BASE'] = "http://localhost:8000/api/v1"
response = completion(
model="lemonade/your-model-name",
messages=[
{"role": "user", "content": "Hello from LiteLLM!"}
],
)
print(response)
```
## Streaming
```python
from litellm import completion
import os
# Optional: Set custom API base. Useful if your lemonade server is on
# a different port
os.environ['LEMONADE_API_BASE'] = "http://localhost:8000/api/v1"
response = completion(
model="lemonade/your-model-name",
messages=[
{"role": "user", "content": "Write a short story"}
],
stream=True
)
for chunk in response:
print(chunk.choices[0].delta.content, end='', flush=True)
```
## Advanced Usage
### Custom Parameters
Lemonade supports additional parameters beyond the standard OpenAI set:
```python
from litellm import completion
response = completion(
model="lemonade/your-model-name",
messages=[{"role": "user", "content": "Explain quantum computing"}],
temperature=0.7,
max_tokens=500,
top_p=0.9,
top_k=50,
repeat_penalty=1.1,
stop=["Human:", "AI:"]
)
print(response)
```
### Function Calling
Lemonade supports OpenAI-compatible function calling:
```python
from litellm import completion
functions = [
{
"name": "get_weather",
"description": "Get current weather information",
"parameters": {
"type": "object",
"properties": {
"location": {
"type": "string",
"description": "The city and state"
}
},
"required": ["location"]
}
}
]
response = completion(
model="lemonade/your-model-name",
messages=[{"role": "user", "content": "What's the weather in San Francisco?"}],
tools=[{"type": "function", "function": f} for f in functions],
tool_choice="auto"
)
print(response)
```
### Response Format
Lemonade supports structured output with response format:
```python
from litellm import completion
import json
# Define schema in response_format
response = completion(
model="lemonade/Qwen3-Coder-30B-A3B-Instruct-GGUF",
messages=[{"role": "user", "content": "Generate JSON data for a person with their name, age, and city."}],
response_format={
"type": "json_schema",
"json_schema": {
"name": "person",
"schema": {
"type": "object",
"properties": {
"name": {"type": "string"},
"age": {"type": "integer"},
"city": {"type": "string"}
},
"required": ["name", "age"]
}
}
}
)
print(f"Model: {response.model}")
print(f"JSON Output:")
json_data = json.loads(response.choices[0].message.content)
print(json.dumps(json_data, indent=2))
```
## Available Models
Lemonade automatically validates available models by querying the `/models` endpoint. You can check available models programmatically:
```python
import httpx
api_base = "http://localhost:8000" # or your custom base
response = httpx.get(f"{api_base}/api/v1/models")
models = response.json()
print("Available models:", [model['id'] for model in models.get('data', [])])
```

query="GPU performance",
documents=["High performance computing", "Fast GPU processing"],
top_n=2,
truncate="END", # Nvidia-specific parameter
)
```
## Authentication
Set your Nvidia NIM API key:
<Tabs>
<TabItem value="env" label="Environment Variable">
```bash
export NVIDIA_NIM_API_KEY="nvapi-..."
```
</TabItem>
<TabItem value="python" label="Python">
```python
import os
os.environ['NVIDIA_NIM_API_KEY'] = "nvapi-..."
# Or pass directly
response = litellm.rerank(
model="nvidia_nim/nvidia/llama-3_2-nv-rerankqa-1b-v2",
query="test",
documents=["doc1"],
api_key="nvapi-...",
)
```
</TabItem>
</Tabs>
## API Endpoint
The rerank endpoint uses a different base URL than chat/embeddings:
- **Chat/Embeddings:** `https://integrate.api.nvidia.com/v1/`
- **Rerank:** `https://ai.api.nvidia.com/v1/`
LiteLLM automatically uses the correct endpoint for rerank requests.
### Custom API Base URL
You can override the default base URL in several ways:
**Option 1: Environment Variable**
```bash
export NVIDIA_NIM_API_BASE="https://your-custom-endpoint.com"
```
**Option 2: Pass as parameter**
```python
response = litellm.rerank(
model="nvidia_nim/nvidia/llama-3_2-nv-rerankqa-1b-v2",
query="test",
documents=["doc1"],
api_base="https://your-custom-endpoint.com",
)
```
**Option 3: Full URL (including model path)**
If you have the complete endpoint URL, you can pass it directly:
```python
response = litellm.rerank(
model="nvidia_nim/nvidia/llama-3_2-nv-rerankqa-1b-v2",
query="test",
documents=["doc1"],
api_base="https://your-custom-endpoint.com/v1/retrieval/nvidia/llama-3_2-nv-rerankqa-1b-v2/reranking",
)
```
LiteLLM will detect the full URL (by checking for `/retrieval/` in the path) and use it as-is.
### How do I get an API key?
Get your Nvidia NIM API key from [Nvidia's website](https://developer.nvidia.com/nim/).

# 🆕 OVHCloud AI Endpoints
Leading French Cloud provider in Europe with data sovereignty and privacy.
You can explore the last models we made available in our [catalog](https://endpoints.ai.cloud.ovh.net/catalog).
:::tip
We support ALL OVHCloud AI Endpoints models, just set `model=ovhcloud/<any-model-on-ai-endpoints>` as a prefix when sending litellm requests.
For the complete models catalog, visit https://endpoints.ai.cloud.ovh.net/catalog. **
:::
## Sample usage
### Chat completion
You can define your API key by setting the `OVHCLOUD_API_KEY` environment variable or by overriding the `api_key` parameter. You can generate a key on the [OVHCloud Manager](https://www.ovh.com/manager).
```python
from litellm import completion
import os
# Our API is free but ratelimited for calls without an API key.
os.environ['OVHCLOUD_API_KEY'] = "your-api-key"
response = completion(
model = "ovhcloud/Meta-Llama-3_3-70B-Instruct",
messages = [
{
"role": "user",
"content": "Hello, how are you?",
}
],
max_tokens = 10,
stop = [],
temperature = 0.2,
top_p = 0.9,
user = "user",
api_key = "your-api-key" # Optional if set through the enviromnent variable.
)
print(response)
```
### Streaming
Set the parameter `stream` to `True` to stream a response.
```python
from litellm import completion
import os
os.environ['OVHCLOUD_API_KEY'] = "your-api-key"
response = completion(
model = "ovhcloud/Meta-Llama-3_3-70B-Instruct",
messages = [
{
"role": "user",
"content": "Hello, how are you?",
}
],
max_tokens = 10,
stop = [],
temperature = 0.2,
top_p = 0.9,
user = "user",
api_key = "your-api-key" # Optional if set through the enviromnent variable,
stream = True
)
for part in response:
print(response)
```

Here's how to call a OVHCloud AI Endpoints model with the LiteLLM Proxy Server
1. Modify the config.yaml
```yaml
model_list:
- model_name: my-model
litellm_params:
model: ovhcloud/<your-model-name> # add ovhcloud/ prefix to route as OVHCloud provider
api_key: api-key # api key to send your model
```
2. Start the proxy
```bash
$ litellm --config /path/to/config.yaml
```
3. Send Request to LiteLLM Proxy Server

#### Calling provider api directly
[**Go straight to provider**](../pass_through/vertex_ai.md#context-caching)
##### 1. Create the Cache
First, create the cache by sending a `POST` request to the `cachedContents` endpoint via the LiteLLM proxy.
<Tabs>
<TabItem value="proxy" label="PROXY">
```bash
curl http://0.0.0.0:4000/vertex_ai/v1/projects/{project_id}/locations/{location}/cachedContents \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $LITELLM_KEY" \
-d '{
"model": "projects/{project_id}/locations/{location}/publishers/google/models/gemini-2.5-flash",
"displayName": "example_cache",
"contents": [{
"role": "user",
"parts": [{
"text": ".... a long book to be cached"
}]
}]
}'
```
</TabItem>
</Tabs>
##### 2. Get the Cache Name from the Response
Vertex AI will return a response containing the `name` of the cached content. This name is the identifier for your cached data.
```json
{
"name": "projects/12341234/locations/{location}/cachedContents/123123123123123",
"model": "projects/{project_id}/locations/{location}/publishers/google/models/gemini-2.5-flash",
"createTime": "2025-09-23T19:13:50.674976Z",
"updateTime": "2025-09-23T19:13:50.674976Z",
"expireTime": "2025-09-23T20:13:50.655988Z",
"displayName": "example_cache",
"usageMetadata": {
"totalTokenCount": 1246,
"textCount": 5132
}
}
```
##### 3. Use the Cached Content
Use the `name` from the response as `cachedContent` or `cached_content` in subsequent API calls to reuse the cached information. This is passed in the body of your request to `/chat/completions`.

## **Batch APIs**
Just add the following Vertex env vars to your environment.
```bash
# GCS Bucket settings, used to store batch prediction files in
export GCS_BUCKET_NAME = "litellm-testing-bucket" # the bucket you want to store batch prediction files in
export GCS_PATH_SERVICE_ACCOUNT="/path/to/service_account.json" # path to your service account json file
# Vertex /batch endpoint settings, used for LLM API requests
export GOOGLE_APPLICATION_CREDENTIALS="/path/to/service_account.json" # path to your service account json file
export VERTEXAI_LOCATION="us-central1" # can be any vertex location
export VERTEXAI_PROJECT="my-test-project"
```
### Usage
#### 1. Create a file of batch requests for vertex
LiteLLM expects the file to follow the **[OpenAI batches files format](https://platform.openai.com/docs/guides/batch)**
Each `body` in the file should be an **OpenAI API request**
Create a file called `vertex_batch_completions.jsonl` in the current working directory, the `model` should be the Vertex AI model name
```
{"custom_id": "request-1", "method": "POST", "url": "/v1/chat/completions", "body": {"model": "gemini-1.5-flash-001", "messages": [{"role": "system", "content": "You are a helpful assistant."},{"role": "user", "content": "Hello world!"}],"max_tokens": 10}}
{"custom_id": "request-2", "method": "POST", "url": "/v1/chat/completions", "body": {"model": "gemini-1.5-flash-001", "messages": [{"role": "system", "content": "You are an unhelpful assistant."},{"role": "user", "content": "Hello world!"}],"max_tokens": 10}}
```
#### 2. Upload a File of batch requests
For `vertex_ai` litellm will upload the file to the provided `GCS_BUCKET_NAME`
```python
import os
oai_client = OpenAI(
api_key="sk-1234", # litellm proxy API key
base_url="http://localhost:4000" # litellm proxy base url
)
file_name = "vertex_batch_completions.jsonl" #
_current_dir = os.path.dirname(os.path.abspath(__file__))
file_path = os.path.join(_current_dir, file_name)
file_obj = oai_client.files.create(
file=open(file_path, "rb"),
purpose="batch",
extra_body={"custom_llm_provider": "vertex_ai"}, # tell litellm to use vertex_ai for this file upload
)
```
**Expected Response**

{
"id": "gs://litellm-testing-bucket/litellm-vertex-files/publishers/google/models/gemini-1.5-flash-001/d3f198cd-c0d1-436d-9b1e-28e3f282997a",

"object": "file",
"purpose": "batch",
"status": "uploaded",
"status_details": null
}
```
#### 3. Create a batch
```python
batch_input_file_id = file_obj.id # use `file_obj` from step 2
create_batch_response = oai_client.batches.create(
completion_window="24h",

## Labels
Google enables you to add custom metadata to its `generateContent` and `streamGenerateContent` calls.
This mechanism is useful in Vertex AI because it allows costs and usage tracking over multiple
different applications or users.
### Usage
You can use that feature through LiteLLM by sending `labels` or `metadata` field in your requests.
If the client sets the `labels` field in the request to the LiteLLM,
the LiteLLM will pass the `labels` field to the Vertex AI backend.
If the client sets the `metadata` field in the request to the LiteLLM and the `labels` field is not set,
the LiteLLM will create the `labels` field filled with `metadata` key/value pairs for all string values and
pass it to the Vertex AI backend.
Here is an example JSON request demonstrating the labels usage:
```json
{
"model": "gemini-2.0-flash-lite",
"messages": [
{ "role": "user", "content": "respond in 20 words. who are you?" }
],
"labels": {
"client_app": "acme_comp_financial_app",
"department": "finance",
"project": "acme_ai"
}
}

## **Batch APIs**
Just add the following Vertex env vars to your environment.
```bash
# GCS Bucket settings, used to store batch prediction files in
export GCS_BUCKET_NAME="my-batch-bucket" # the bucket you want to store batch prediction files in
export GCS_PATH_SERVICE_ACCOUNT="/path/to/service_account.json" # path to your service account json file
# Vertex /batch endpoint settings, used for LLM API requests
export GOOGLE_APPLICATION_CREDENTIALS="/path/to/service_account.json" # path to your service account json file
export VERTEXAI_LOCATION="us-central1" # can be any vertex location
export VERTEXAI_PROJECT="my-project"
```
### Usage
Follow this complete workflow: create JSONL file → upload file → create batch → retrieve batch status → get file content
#### 1. Create a JSONL file of batch requests
LiteLLM expects the file to follow the **[OpenAI batches files format](https://platform.openai.com/docs/guides/batch)**.
Each `body` in the file should be an **OpenAI API request**.
Create a file called `batch_requests.jsonl` with your requests:
```jsonl
{"custom_id": "request-1", "method": "POST", "url": "/v1/chat/completions", "body": {"model": "gemini-2.5-flash-lite", "messages": [{"role": "system", "content": "You are a helpful assistant."},{"role": "user", "content": "Hello world!"}],"max_tokens": 10}}
{"custom_id": "request-2", "method": "POST", "url": "/v1/chat/completions", "body": {"model": "gemini-2.5-flash-lite", "messages": [{"role": "system", "content": "You are an unhelpful assistant."},{"role": "user", "content": "Hello world!"}],"max_tokens": 10}}
```
#### 2. Upload the file
Upload your JSONL file. For `vertex_ai`, the file will be stored in your configured GCS bucket provided by `GCS_BUCKET_NAME`.

### Additional Cost Keys
There are other keys you can use to specify costs for different scenarios and modalities:
- `input_cost_per_token_above_200k_tokens` - Cost for input tokens when context exceeds 200k tokens
- `output_cost_per_token_above_200k_tokens` - Cost for output tokens when context exceeds 200k tokens
- `cache_creation_input_token_cost_above_200k_tokens` - Cache creation cost for large contexts
- `cache_read_input_token_cost_above_200k_token` - Cache read cost for large contexts
- `input_cost_per_image` - Cost per image in multimodal requests
- `output_cost_per_reasoning_token` - Cost for reasoning tokens (e.g., OpenAI o1 models)
- `input_cost_per_audio_token` - Cost for audio input tokens
- `output_cost_per_audio_token` - Cost for audio output tokens
- `input_cost_per_video_per_second` - Cost per second of video input
- `input_cost_per_video_per_second_above_128k_tokens` - Video cost for large contexts
- `input_cost_per_character` - Character-based pricing for some providers
These keys evolve based on how new models handle multimodality. The latest version can be found at [https://github.com/BerriAI/litellm/blob/main/model_prices_and_context_window.json](https://github.com/BerriAI/litellm/blob/main/model_prices_and_context_window.json).
## Set 'base_model' for Cost Tracking (e.g. Azure deployments)
**Problem**: Azure returns `gpt-4` in the response when `azure/gpt-4-1106-preview` is used. This leads to inaccurate cost tracking

## Troubleshooting: Redis Connection Errors
You may see errors like:
```
LiteLLM Redis Caching: async async_increment() - Got exception from REDIS No connection available., Writing value=21
LiteLLM Redis Caching: async set_cache_pipeline() - Got exception from REDIS No connection available., Writing value=None
```
This means all available Redis connections are in use, and LiteLLM cannot obtain a new connection from the pool. This can happen under high load or with many concurrent proxy requests.
**Solution:**
- Increase the `max_connections` parameter in your Redis config section in `proxy_config.yaml` to allow more simultaneous connections. For example:
```yaml
litellm_settings:
cache: True
cache_params:
type: redis
max_connections: 100 # Increase as needed for your traffic
```
Adjust this value based on your expected concurrency and Redis server capacity.

Prevent projects from gobbling too much tpm/rpm.
Dynamically allocate TPM/RPM quota to api keys, based on active keys in that minute. [**See Code**](https://github.com/BerriAI/litellm/blob/9bffa9a48e610cc6886fc2dce5c1815aeae2ad46/litellm/proxy/hooks/dynamic_rate_limiter.py#L125)
## Quick Start Usage
1. Setup config.yaml
```yaml showLineNumbers title="config.yaml"
model_list:
- model_name: my-fake-model
litellm_params:
model: gpt-3.5-turbo
api_key: my-fake-key

raise Exception("This should have failed!")
except RateLimitError as e:
print("This was rate limited b/c - {}".format(str(e)))
```
**Expected Response**
```
This was rate limited b/c - Error code: 429 - {'error': {'message': {'error': 'Key=<hashed_token> over available TPM=0. Model TPM=0, Active keys=2'}, 'type': 'None', 'param': 'None', 'code': 429}}
```
## [BETA] Set Priority / Reserve Quota
Reserve TPM/RPM capacity for different environments or use cases. This ensures critical production workloads always have guaranteed capacity, while development or lower-priority tasks use remaining quota.
**Use Cases:**
- Production vs Development environments
- Real-time applications vs batch processing
- Critical services vs experimental features
:::tip
Reserving TPM/RPM on keys based on priority is a premium feature. Please [get an enterprise license](./enterprise.md) for it.
:::
### How Priority Reservation Works
Priority reservation allocates a percentage of your model's total TPM/RPM to specific priority levels. Keys with higher priority get guaranteed access to their reserved quota first.
**Example Scenario:**
- Model has 10 RPM total capacity
- Priority reservation: `{"prod": 0.9, "dev": 0.1}`
- Result: Production keys get 9 RPM guaranteed, Development keys get 1 RPM guaranteed
### Configuration
#### 1. Setup config.yaml
```yaml showLineNumbers title="config.yaml"
model_list:
- model_name: gpt-3.5-turbo
litellm_params:
model: "gpt-3.5-turbo"
api_key: os.environ/OPENAI_API_KEY
rpm: 10 # Total model capacity
litellm_settings:
callbacks: ["dynamic_rate_limiter_v3"]
priority_reservation:
"prod": 0.9 # 90% reserved for production (9 RPM)
"dev": 0.1 # 10% reserved for development (1 RPM)
priority_reservation_settings:
default_priority: 0 # Weight (0%) assigned to keys without explicit priority metadata
saturation_threshold: 0.50 # A model is saturated if it has hit 50% of its RPM limit
general_settings:
master_key: sk-1234 # OR set `LITELLM_MASTER_KEY=".."` in your .env
database_url: postgres://.. # OR set `DATABASE_URL=".."` in your.env
```
**Configuration Details:**
`priority_reservation`: Dict[str, float]
- **Key (str)**: Priority level name (can be any string like "prod", "dev", "critical", etc.)
- **Value (float)**: Percentage of total TPM/RPM to reserve (0.0 to 1.0)
- **Note**: Values should sum to 1.0 or less
`priority_reservation_settings`: Object (Optional)
- **default_priority (float)**: Weight/percentage (0.0 to 1.0) assigned to API keys that have no priority metadata set (defaults to 0.5)
- **saturation_threshold (float)**: Saturation level (0.0 to 1.0) at which strict priority enforcement begins for a model. Saturation is calculated as `max(current_rpm/max_rpm, current_tpm/max_tpm)`. Below this threshold, generous mode allows priority borrowing from unused capacity. Above this threshold, strict mode enforces normalized priority limits.
- Example: When model usage is low, keys can use more than their allocated share. When model usage is high, keys are strictly limited to their allocated share.
**Start Proxy**
```bash
litellm --config /path/to/config.yaml
```
#### 2. Create Keys with Priority Levels
**Production Key:**
```bash
curl -X POST 'http://0.0.0.0:4000/key/generate' \
-H 'Authorization: Bearer sk-1234' \
-H 'Content-Type: application/json' \
-d '{
"metadata": {"priority": "prod"}
}'
```
**Development Key:**
```bash
curl -X POST 'http://0.0.0.0:4000/key/generate' \
-H 'Authorization: Bearer sk-1234' \
-H 'Content-Type: application/json' \
-d '{
"metadata": {"priority": "dev"}
}'
```
**Key Without Priority (uses default_priority weight):**
```bash
curl -X POST 'http://0.0.0.0:4000/key/generate' \
-H 'Authorization: Bearer sk-1234' \
-H 'Content-Type: application/json' \
-d '{}'
```
**Expected Response for both:**
```json
{
"key": "sk-...",
"metadata": {"priority": "prod"}, // or "dev"
...
}
```
#### 3. Test Priority Allocation
**Test Production Key (should get 9 RPM):**
```bash
curl -X POST 'http://0.0.0.0:4000/chat/completions' \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer sk-prod-key' \
-d '{
"model": "gpt-3.5-turbo",
"messages": [{"role": "user", "content": "Hello from prod"}]
}'
```
**Test Development Key (should get 1 RPM):**
```bash
curl -X POST 'http://0.0.0.0:4000/chat/completions' \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer sk-dev-key' \
-d '{
"model": "gpt-3.5-turbo",
"messages": [{"role": "user", "content": "Hello from dev"}]
}'
```
### Expected Behavior
With the configuration above:
1. **Production keys** can make up to 9 requests per minute (90% of 10 RPM)
2. **Development keys** can make up to 1 request per minute (10% of 10 RPM)
3. **Keys without explicit priority** get the default_priority weight (0 = 0%), which allocates 0 requests per minute (0% of 10 RPM)
4. Named priorities in `priority_reservation` and keys with `default_priority` operate independently
**Rate Limit Error Example:**
```json
{
"error": {
"message": "Key=sk-dev-... over available RPM=0. Model RPM=10, Reserved RPM for priority 'dev'=1, Active keys=1",
"type": "rate_limit_exceeded",
"code": 429
}
}
```

# Forward Client Headers to LLM API
Control which model groups can forward client headers to the underlying LLM provider APIs.
## Overview
By default, LiteLLM does not forward client headers to LLM provider APIs for security reasons. However, you can selectively enable header forwarding for specific model groups using the `forward_client_headers_to_llm_api` setting.
## Configuration
## Enable Globally
```yaml
general_settings:
forward_client_headers_to_llm_api: true
```
## Enable for a Model Group
Add the `forward_client_headers_to_llm_api` setting under `model_group_settings` in your configuration:
```yaml
model_list:
- model_name: gpt-4o-mini
litellm_params:
model: openai/gpt-4o-mini
api_key: "your-api-key"
- model_name: "wildcard-models/*"
litellm_params:
model: "openai/*"
api_key: "your-api-key"
litellm_settings:
model_group_settings:
forward_client_headers_to_llm_api:
- gpt-4o-mini
- wildcard-models/*
```
## Supported Model Patterns
The configuration supports various model matching patterns:
### 1. Exact Model Names
```yaml
forward_client_headers_to_llm_api:
- gpt-4o-mini
- claude-3-sonnet
```
### 2. Wildcard Patterns
```yaml
forward_client_headers_to_llm_api:
- "openai/*" # All OpenAI models
- "anthropic/*" # All Anthropic models
- "wildcard-group/*" # All models in wildcard-group
```
### 3. Team Model Aliases
If your team has model aliases configured, the forwarding will work with both the original model name and the alias.
## Forwarded Headers
When enabled for a model group, LiteLLM forwards the following types of headers:
### Custom Headers (x- prefix)
- Any header starting with `x-` (except `x-stainless-*` which can cause OpenAI SDK issues)
- Examples: `x-custom-header`, `x-request-id`, `x-trace-id`
### Provider-Specific Headers
- **Anthropic**: `anthropic-beta` headers
- **OpenAI**: `openai-organization` (when enabled via `forward_openai_org_id: true`)
### User Information Headers (Optional)
When `add_user_information_to_llm_headers` is enabled, LiteLLM adds:
- `x-litellm-user-id`
- `x-litellm-org-id`
- Other user metadata as `x-litellm-*` headers
## Security Considerations
⚠️ **Important Security Notes:**
1. **Sensitive Data**: Only enable header forwarding for trusted model groups, as headers may contain sensitive information
2. **API Keys**: Never include API keys or secrets in forwarded headers
3. **PII**: Be cautious about forwarding headers that might contain personally identifiable information
4. **Provider Limits**: Some providers have restrictions on custom headers
## Example Use Cases
### 1. Request Tracing
Forward tracing headers to track requests across your system:
```bash
curl -X POST "https://your-proxy.com/v1/chat/completions" \
-H "Authorization: Bearer your-key" \
-H "x-trace-id: abc123" \
-H "x-request-source: mobile-app" \
-d '{
"model": "gpt-4o-mini",
"messages": [{"role": "user", "content": "Hello"}]
}'
```
### 2. Custom Metadata
Pass custom metadata to your LLM provider:
```bash
curl -X POST "https://your-proxy.com/v1/chat/completions" \
-H "Authorization: Bearer your-key" \
-H "x-customer-id: customer-123" \
-H "x-environment: production" \
-d '{
"model": "gpt-4o-mini",
"messages": [{"role": "user", "content": "Hello"}]
}'
```
### 3. Anthropic Beta Features
Enable beta features for Anthropic models:
```bash
curl -X POST "https://your-proxy.com/v1/chat/completions" \
-H "Authorization: Bearer your-key" \
-H "anthropic-beta: tools-2024-04-04" \
-d '{
"model": "claude-3-sonnet",
"messages": [{"role": "user", "content": "Hello"}]
}'
```
## Complete Configuration Example
```yaml
model_list:
# Fixed model with header forwarding
- model_name: byok-fixed-gpt-4o-mini
litellm_params:
model: openai/gpt-4o-mini
api_base: "https://your-openai-endpoint.com"
api_key: "your-api-key"
# Wildcard model group with header forwarding
- model_name: "byok-wildcard/*"
litellm_params:
model: "openai/*"
api_base: "https://your-openai-endpoint.com"
api_key: "your-api-key"
# Standard model without header forwarding
- model_name: standard-gpt-4
litellm_params:
model: openai/gpt-4
api_key: "your-api-key"
litellm_settings:
# Enable user info headers globally (optional)
add_user_information_to_llm_headers: true
model_group_settings:
forward_client_headers_to_llm_api:
- byok-fixed-gpt-4o-mini
- byok-wildcard/*
# Note: standard-gpt-4 is NOT included, so no headers forwarded
general_settings:
# Enable OpenAI organization header forwarding (optional)
forward_openai_org_id: true
```
## Testing Header Forwarding
To test if headers are being forwarded:
1. **Enable Debug Logging**: Set `set_verbose: true` in your config
2. **Check Provider Logs**: Monitor your LLM provider's request logs
3. **Use Webhook Sites**: For testing, you can use webhook.site URLs as api_base to see forwarded headers
## Troubleshooting
### Headers Not Being Forwarded
1. **Check Model Name**: Ensure the model name in your request matches the configuration
2. **Verify Pattern Matching**: Wildcard patterns must match exactly
3. **Review Logs**: Enable verbose logging to see header processing
### Provider Errors
1. **Invalid Headers**: Some providers reject unknown headers
2. **Header Limits**: Providers may have limits on header count/size
3. **Authentication**: Ensure forwarded headers don't conflict with authentication

- [Team Model Aliases](./team_model_add.md) - Configure model aliases for teams
- [Model Access Control](./model_access.md) - Control which users can access which models
## API Reference
The header forwarding is controlled by the `ModelGroupSettings` configuration:
```python
class ModelGroupSettings(BaseModel):
forward_client_headers_to_llm_api: Optional[List[str]] = None
```
Where each string in the list can be:
- An exact model name (e.g., `"gpt-4o-mini"`)
- A wildcard pattern (e.g., `"openai/*"`)
- A model group name (e.g., `"my-model-group/*"`)

## Supported Guardrail Types
### 1. Prompt Injection Detection (`promptinjectiondetection`)
Detects and blocks prompt injection and jailbreak attempts.
**Categories:**
- `prompt_injection`: Detects attempts to manipulate the AI system
- `jailbreak`: Detects attempts to bypass safety measures
**Example Response:**
```json
{
"assessments": [
{
"promptinjectiondetection": {
"request_reject": true,
"results": {
"categories": {
"jailbreak": false,
"prompt_injection": true
},
"category_scores": {
"jailbreak": 0.04,
"prompt_injection": 0.97
},
"reject_prompt": "Unable to complete request, prompt injection/jailbreak detected"
}
}
}
]
}
```
### 2. Trust & Safety (`trustsafety`)
Detects harmful content across multiple categories.
**Categories:**
- `violence`: Violence-related content
- `weapons`: Weapon-related content
- `hate_speech`: Hate speech and discriminatory content
- `crime`: Criminal activity content
- `sexual`: Sexual content
- `profanity`: Profane language
**Example Response:**
```json
{
"assessments": [
{
"trustsafety": {
"request_reject": true,
"results": {
"categories": {
"violence": true,
"weapons": true,
"hate_speech": false,
"crime": false,
"sexual": false,
"profanity": false
},
"category_scores": {
"violence": 0.95,
"weapons": 0.88,
"hate_speech": 0.02,
"crime": 0.03,
"sexual": 0.01,
"profanity": 0.01
},
"reject_prompt": "Unable to complete request, trust & safety violation detected"
}
}
}
]
}
```
### 3. Language Detection (`lang_detector`)
Detects the language of input text and can enforce language policies.
**Example Response:**
```json
{
"assessments": [
{
"lang_detector": {
"request_reject": true,
"results": {
"lang": "hi",
"prob": 0.95,
"reject_prompt": "Unable to complete request, language violation detected"
}
}
}
]
}
```
## Supported Params
```yaml
guardrails:
- guardrail_name: "javelin-guard"
litellm_params:
guardrail: javelin
mode: "pre_call"
api_key: os.environ/JAVELIN_API_KEY
api_base: os.environ/JAVELIN_API_BASE
guardrail_name: "promptinjectiondetection" # or "trustsafety", "lang_detector"
api_version: "v1"
### OPTIONAL ###
# metadata: Optional[Dict] = None,
# config: Optional[Dict] = None,
# application: Optional[str] = None,
# default_on: bool = True
```
- `api_base`: (Optional[str]) The base URL of the Javelin API. Defaults to `https://api-dev.javelin.live`
- `api_key`: (str) The API Key for the Javelin integration.
- `guardrail_name`: (str) The type of guardrail to use. Supported values: `promptinjectiondetection`, `trustsafety`, `lang_detector`
- `api_version`: (Optional[str]) The API version to use. Defaults to `v1`
- `metadata`: (Optional[Dict]) Metadata tags can be attached to screening requests as an object that can contain any arbitrary key-value pairs.
- `config`: (Optional[Dict]) Configuration parameters for the guardrail.
- `application`: (Optional[str]) Application name for policy-specific guardrails.
- `default_on`: (Optional[bool]) Whether the guardrail is enabled by default. Defaults to `True`
## Environment Variables
Set the following environment variables:
```bash
export JAVELIN_API_KEY="your-javelin-api-key"
export JAVELIN_API_BASE="https://api-dev.javelin.live" # Optional, defaults to dev environment
```
## Error Handling
When a guardrail detects a violation:
1. The **last message content** is replaced with the appropriate reject prompt
2. The message role remains unchanged
3. The request continues with the modified message
4. The original violation is logged for monitoring
**How it works:**
- Javelin guardrails check the last message for violations
- If a violation is detected (`request_reject: true`), the content of the last message is replaced with the reject prompt
- The message structure remains intact, only the content changes
**Reject Prompts:**
Can be configured from javelin portal.
- Prompt Injection: `"Unable to complete request, prompt injection/jailbreak detected"`
- Trust & Safety: `"Unable to complete request, trust & safety violation detected"`
- Language Detection: `"Unable to complete request, language violation detected"`
## Testing
You can test the Javelin guardrails using the provided test suite:
```bash
pytest tests/guardrails_tests/test_javelin_guardrails.py -v
```
The tests include mocked responses to avoid external API calls during testing.

# Tool Permission Guardrail
LiteLLM provides a Tool Permission Guardrail that lets you control which **tool calls** a model is allowed to invoke, using configurable allow/deny rules. This offers fine-grained, provider-agnostic control over tool execution (e.g., OpenAI Chat Completions `tool_calls`, Anthropic Messages `tool_use`, MCP tools).
## Quick Start
### 1. Define Guardrails on your LiteLLM config.yaml
Define your guardrails under the `guardrails` section
```yaml
guardrails:
- guardrail_name: "tool-permission-guardrail"
litellm_params:
guardrail: tool_permission
mode: "post_call"
rules:
- id: "allow_bash"
tool_name: "Bash"
decision: "allow"
- id: "allow_github_mcp"
tool_name: "mcp__github_*"
decision: "allow"
- id: "allow_aws_documentation"
tool_name: "mcp__aws-documentation_*_documentation"
decision: "allow"
- id: "deny_read_commands"
tool_name: "Read"
decision: "Deny"
default_action: "deny" # Fallback when no rule matches: "allow" or "deny"
on_disallowed_action: "block" # How to handle disallowed tools: "block" or "rewrite"
```
#### Rule Structure
```yaml
- id: "unique_rule_id" # Unique identifier for the rule
tool_name: "pattern" # Tool name or pattern to match
decision: "allow" # "allow" or "deny"
```
#### Supported values for `mode`
- `pre_call` Run **before** LLM call, on **input**
- `post_call` Run **after** LLM call, on **input & output**
### 2. Start the Proxy
```shell
litellm --config config.yaml --port 4000

The `cost_breakdown` field provides detailed cost breakdown for completion requests as a `CostBreakdown` object containing:
- **`input_cost`**: Cost of input/prompt tokens including cache creation tokens
- **`output_cost`**: Cost of output/completion tokens (including reasoning tokens if applicable)
- **`tool_usage_cost`**: Cost of built-in tools usage (e.g., web search, code interpreter)
- **`total_cost`**: Total cost of input + output + tool usage
**Note**: This field is populated for all call types. For non-completion calls, `input_cost` and `output_cost` may be 0.
The total cost relationship is: `response_cost = cost_breakdown.total_cost`

# LiteLLM Self-Hosted Security & Encryption FAQ
## Data in Transit Encryption
### Does the product encrypt data in transit?
**Yes**, LiteLLM encrypts data in transit using TLS/SSL.
### Available in both OSS and Enterprise?
**Yes**, TLS encryption is available in both Open Source and Enterprise versions.
### In transit between the calling client and the product?
**Yes**, HTTPS/TLS is supported through SSL certificate configuration.
**Configuration:**
```bash
# CLI
litellm --ssl_keyfile_path /path/to/key.pem --ssl_certfile_path /path/to/cert.pem
# Environment Variables
export SSL_KEYFILE_PATH="/path/to/key.pem"
export SSL_CERTFILE_PATH="/path/to/cert.pem"
```
**Documentation Reference:** `docs/my-website/docs/guides/security_settings.md`
### In transit between the product and the LLM providers?
**Yes**, all connections to LLM providers use TLS encryption by default.
**Implementation Details:**
- Uses Python's `ssl.create_default_context()`
- Leverages HTTPX and aiohttp libraries with SSL/TLS enabled
- Uses certifi CA bundle by default for SSL verification
**Code Reference:** `litellm/llms/custom_httpx/http_handler.py` (lines 43-105)
### Are TCP sessions to the LLM providers shared?
**Yes**, TCP connections are pooled and reused.
**Details:**
- Connection pooling is enabled by default
- Default: 1000 max concurrent connections with keepalive
- Sessions are maintained across requests to the same provider
- Reduces overhead of TLS handshakes
**Code Reference:** `litellm/llms/custom_httpx/http_handler.py` (lines 704-712)
### Or does the product negotiate a new TLS session with the same LLM provider for every sequential call?
**No**, TLS sessions are reused through connection pooling. New TLS handshakes are not performed for every request.
### How is it encrypted?
**TLS 1.2 and TLS 1.3**
Uses Python's default SSL context which supports both TLS 1.2 and TLS 1.3. The specific version negotiated depends on:
- Python version
- System SSL library (typically OpenSSL)
- Server capabilities
**Implementation:** `ssl.create_default_context()` in Python
### How are these added to the product's configuration?
#### x.509 Certificate
**Method 1: CLI Arguments**
```bash
litellm --ssl_certfile_path /path/to/certificate.pem
```
**Method 2: Environment Variable**
```bash
export SSL_CERTFILE_PATH="/path/to/certificate.pem"
```
#### Private Key
**Method 1: CLI Arguments**
```bash
litellm --ssl_keyfile_path /path/to/private_key.pem
```
**Method 2: Environment Variable**
```bash
export SSL_KEYFILE_PATH="/path/to/private_key.pem"
```
#### Certificate Bundle/Chain
**For client-to-proxy connections:**
Use standard SSL certificate setup with intermediate certificates bundled in the certfile.
**For proxy-to-LLM provider connections:**
**Method 1: Config YAML**
```yaml
litellm_settings:
ssl_verify: "/path/to/ca_bundle.pem"
```
**Method 2: Environment Variable**
```bash
export SSL_CERT_FILE="/path/to/ca_bundle.pem"
```
**Method 3: Client Certificate Authentication**
```yaml
litellm_settings:
ssl_certificate: "/path/to/client_certificate.pem"
```
or
```bash
export SSL_CERTIFICATE="/path/to/client_certificate.pem"
```

## Data at Rest Encryption
### Does the product encrypt data at rest?
**Partially**. Only specific sensitive data is encrypted at rest.
### What data is stored in encrypted form?
#### Encrypted Data:
1. **LLM API Keys** - Model credentials in `LiteLLM_ProxyModelTable.litellm_params`
2. **Provider Credentials** - Stored in `LiteLLM_CredentialsTable.credential_values`
3. **Configuration Secrets** - Sensitive config values in `LiteLLM_Config` table
4. **Virtual Keys** - When using secret managers (optional feature)
#### NOT Encrypted:
1. **Spend Logs** - Request/response data in `LiteLLM_SpendLogs`
2. **Audit Logs** - Change history in `LiteLLM_AuditLog`
3. **User/Team/Organization Data** - Metadata and configuration
4. **Cached Prompts and Completions** - Cache data is stored in plaintext
### Cached prompts and completions?
**No**, cached prompts and completions are **NOT encrypted**.
Cache backends (Redis, S3, local disk) store data as plaintext JSON.
**Code References:**
- `litellm/caching/redis_cache.py`
- `litellm/caching/s3_cache.py`
- `litellm/caching/caching.py`
### Configuration data?
**Partially encrypted**.
#### What IS Encrypted:
- LLM API keys and credentials in model configurations
- Sensitive values in `LiteLLM_Config` table
- Credential values in `LiteLLM_CredentialsTable`
#### What is NOT Encrypted:
- Model names and aliases
- Rate limits and budget settings
- User/team/organization metadata
- Non-sensitive configuration parameters
**Code Reference:** `litellm/proxy/management_endpoints/model_management_endpoints.py` (lines 275-308)
### Log data?
**No**, log data is **NOT encrypted**.
Log data stored in database tables is in plaintext:
- `LiteLLM_SpendLogs` - Contains request/response data, tokens, spend
- `LiteLLM_ErrorLogs` - Error information
- `LiteLLM_AuditLog` - Audit trail of changes
**Note:** You can disable logging to avoid storing sensitive data:
```yaml
general_settings:
disable_spend_logs: True # Disable writing spend logs to DB
disable_error_logs: True # Disable writing error logs to DB
```
**Documentation:** `docs/my-website/docs/proxy/db_info.md` (lines 52-60)
### Where is it stored?
#### In the DB?
**Yes**, encrypted data is stored in PostgreSQL database.
**Key Tables with Encrypted Data:**
- `LiteLLM_ProxyModelTable` - Model configurations with encrypted API keys
- `LiteLLM_CredentialsTable` - Credential values
- `LiteLLM_Config` - Configuration secrets
**Schema Reference:** `schema.prisma`
#### In the filesystem?
**No**, encrypted data is not stored in the filesystem by default.
**Note:** If using disk cache (`disk_cache_dir`), cached data is stored unencrypted.
#### Somewhere else?
**Optional:** When using secret managers (AWS Secrets Manager, Azure Key Vault, HashiCorp Vault), encrypted data can be stored externally.
**Configuration:**
```yaml
general_settings:
key_management_system: "aws_secret_manager" # or "azure_key_vault", "hashicorp_vault"
```
**Documentation:** `docs/my-website/docs/secret.md`
### How is it encrypted?
**Algorithm:** NaCl SecretBox (XSalsa20-Poly1305 AEAD)
**NOT AES-256** - LiteLLM uses NaCl (Networking and Cryptography Library) which provides:
- XSalsa20 stream cipher
- Poly1305 MAC for authentication
- Equivalent security to AES-256
**Key Derivation:**
1. Takes `LITELLM_SALT_KEY` (or `LITELLM_MASTER_KEY` if salt key not set)
2. Hashes with SHA-256 to derive 256-bit encryption key
3. Uses NaCl SecretBox for authenticated encryption
**Code Reference:** `litellm/proxy/common_utils/encrypt_decrypt_utils.py` (lines 69-112)
**Implementation:**
```python
import hashlib
import nacl.secret
# Derive 256-bit key from salt
hash_object = hashlib.sha256(signing_key.encode())
hash_bytes = hash_object.digest()
# Create SecretBox and encrypt
box = nacl.secret.SecretBox(hash_bytes)
encrypted = box.encrypt(value_bytes)
```
### Setting the Encryption Key
**Required Environment Variable:**
```bash
export LITELLM_SALT_KEY="your-strong-random-key-here"
```
**Important Notes:**
- ⚠️ **Must be set before adding any models**
- ⚠️ **Never change this key** - encrypted data becomes unrecoverable
- ⚠️ Use a strong random key (recommended: https://1password.com/password-generator/)
- If not set, falls back to `LITELLM_MASTER_KEY`
**Documentation:** `docs/my-website/docs/proxy/prod.md` (section 8, lines 184-196)

#### ✨ [BETA] Set Priority / Reserve Quota
Reserve tpm/rpm capacity for projects in prod.
:::tip
Reserving tpm/rpm on keys based on priority is a premium feature. Please [get an enterprise license](./enterprise.md) for it.
:::
1. Setup config.yaml
```yaml
model_list:
- model_name: gpt-3.5-turbo
litellm_params:
model: "gpt-3.5-turbo"
api_key: os.environ/OPENAI_API_KEY
rpm: 100
litellm_settings:
callbacks: ["dynamic_rate_limiter"]
priority_reservation: {"dev": 0, "prod": 1}
general_settings:
master_key: sk-1234 # OR set `LITELLM_MASTER_KEY=".."` in your .env
database_url: postgres://.. # OR set `DATABASE_URL=".."` in your .env
```
priority_reservation:
- Dict[str, float]
- str: can be any string
- float: from 0 to 1. Specify the % of tpm/rpm to reserve for keys of this priority.
**Start Proxy**
```
litellm --config /path/to/config.yaml
```
2. Create a key with that priority
```bash
curl -X POST 'http://0.0.0.0:4000/key/generate' \
-H 'Authorization: Bearer <your-master-key>' \
-H 'Content-Type: application/json' \
-D '{
"metadata": {"priority": "dev"} # 👈 KEY CHANGE
}'
```
**Expected Response**
```
{
...
"key": "sk-.."
}
```
3. Test it!
```bash
curl -X POST 'http://0.0.0.0:4000/chat/completions' \
-H 'Content-Type: application/json' \
-H 'Authorization: sk-...' \ # 👈 key from step 2.
-d '{
"model": "gpt-3.5-turbo",
"messages": [
{
"role": "user",
"content": "what llm are you"
}
],
}'
```
**Expected Response**
```
Key=... over available RPM=0. Model RPM=100, Active keys=None
```

## Model Management
The Admin UI provides comprehensive model management capabilities:
- **Add Models**: Add new models through the UI without restarting the proxy
- **Model Hub**: Make models public for developers to discover available models
- **Price Data Sync**: Keep model pricing data up to date by syncing from GitHub
For detailed information on model management, see [Model Management](./model_management.md).
:::tip Sync Model Pricing Data
[Sync model pricing data from GitHub](./sync_models_github.md) to keep your model cost information current.

# User Onboarding Guide
A step-by-step guide to help admins onboard users to your LiteLLM proxy instance and help users get started with their API key.
---
## For Administrators
### Step 1: Create a User Account
You can create a user account via the Admin UI or using the API.
#### Admin UI
- Go to the (`/ui` endpoint)
- Navigate to the Internal Users section
- Click "Add User" and fill in the required details
#### API
```bash
curl -X POST http://localhost:4000/user/new \
-H "Authorization: Bearer <admin-key>" \
-H "Content-Type: application/json" \
-d '{"user_email": "user@example.com"}'
```
---
### Step 2: Grant Access & Permissions
- Assign the user to a team (optional)
- Set budgets, rate limits, and allowed models as needed
- Generate an API key for the user (via UI or API)
#### **Generate API Key (API Example)**
```bash
curl -X POST http://localhost:4000/key/generate \
-H "Authorization: Bearer <admin-key>" \
-H "Content-Type: application/json" \
-d '{"user_id": "<user-id>", "max_budget": 100}'
```
---
## For End Users
### Step 3: Validate Your API Key
Before making LLM calls, validate your key works by calling the `/v1/models` endpoint:
```bash
curl -X GET http://localhost:4000/v1/models \
-H "Authorization: Bearer <your-api-key>"
```
- If your key is valid, you'll get a list of available models.
- If invalid, you'll get a 401 error.
---
### Step 4: Hello World - Make Your First LLM Call
```bash
curl -X POST http://localhost:4000/v1/chat/completions \
-H "Authorization: Bearer <your-api-key>" \
-H "Content-Type: application/json" \
-d '{
"model": "gpt-3.5-turbo",
"messages": [{"role": "user", "content": "Hello!"}]
}'
```
---
## Troubleshooting
- If you get a 401 error, check with your admin that your key is active and you have access to the requested model.
- Use the `/v1/models` endpoint to quickly check if your key is valid without consuming LLM tokens.

## 🔁 Scheduled Key Rotations (NEW in v1.77.5)
LiteLLM can now rotate **virtual keys automatically** on a schedule you define.
### How it works
1. When creating a virtual key you set `rotation_schedule` – a [cron expression](https://crontab.guru/).
2. LiteLLM stores the schedule in the DB and runs a background job that regenerates the key at the specified time.
3. Existing key string is invalidated; a **notification webhook** (if configured) is sent with the new key value.
### Create a key with rotation
```bash
curl 'http://0.0.0.0:4000/key/generate' \
-H 'Authorization: Bearer <your-master-key>' \
-H 'Content-Type: application/json' \
-d '{
"models": ["gpt-4o"],
"rotation_schedule": "0 0 * * SUN", # rotate every Sunday at 00:00 UTC
"webhook_url": "https://example.com/key-rotated"
}'
```
### Enable globally via env
Set these env vars when starting the proxy:
| Variable | Description | Default |
|----------|-------------|---------|
| `LITELLM_KEY_ROTATION_ENABLED` | Enable the rotation worker | `false` |
| `LITELLM_KEY_ROTATION_CHECK_INTERVAL_SECONDS` | How often to scan for keys to rotate | `86400` |
### Webhook payload
```json
{
"event": "virtual_key.rotated",
"old_key_id": "sk-abc...",
"new_key": "sk-def...",
"rotation_time": "2025-10-05T00:00:00Z"
}
```
If no `webhook_url` is provided the new key value is returned in the response of the `/key/rotate` REST call instead.
