# Braintrust Prompt Wrapper for LiteLLM
This directory contains a wrapper server that enables LiteLLM to use prompts from [Braintrust](https://www.braintrust.dev/) through the generic prompt management API.
## Architecture
```
┌─────────────┐ ┌──────────────────────┐ ┌─────────────┐
│ LiteLLM │ ──────> │ Wrapper Server │ ──────> │ Braintrust │
│ Client │ │ (This Server) │ │ API │
└─────────────┘ └──────────────────────┘ └─────────────┘
Uses generic Transforms Stores actual
prompt manager Braintrust format prompt templates
to LiteLLM format
```
## Components
### 1. Generic Prompt Manager (`litellm/integrations/generic_prompt_management/`)
A generic client that can work with any API implementing the `/beta/litellm_prompt_management` endpoint.
**Expected API Response Format:**
```json
{
"prompt_id": "string",
"prompt_template": [
{"role": "system", "content": "You are a helpful assistant"},
{"role": "user", "content": "Hello {name}"}
],
"prompt_template_model": "gpt-4",
"prompt_template_optional_params": {
"temperature": 0.7,
"max_tokens": 100
}
}
```
### 2. Braintrust Wrapper Server (`braintrust_prompt_wrapper_server.py`)
A FastAPI server that:
- Implements the `/beta/litellm_prompt_management` endpoint
- Fetches prompts from Braintrust API
- Transforms Braintrust response format to LiteLLM format
## Setup
### Install Dependencies
```bash
pip install fastapi uvicorn httpx litellm
```
### Set Environment Variables
```bash
export BRAINTRUST_API_KEY="your-braintrust-api-key"
```
## Usage
### Step 1: Start the Wrapper Server
```bash
python braintrust_prompt_wrapper_server.py
```
The server will start on `http://localhost:8080` by default.
You can customize the port and host:
```bash
export PORT=8000
export HOST=0.0.0.0
python braintrust_prompt_wrapper_server.py
```
### Step 2: Use with LiteLLM
```python
import litellm
from litellm.integrations.generic_prompt_management import GenericPromptManager
# Configure the generic prompt manager to use your wrapper server
generic_config = {
"api_base": "http://localhost:8080",
"api_key": "your-braintrust-api-key", # Will be passed to Braintrust
"timeout": 30,
}
# Create the prompt manager
prompt_manager = GenericPromptManager(**generic_config)
# Use with completion
response = litellm.completion(
model="generic_prompt/gpt-4",
prompt_id="your-braintrust-prompt-id",
prompt_variables={"name": "World"}, # Variables to substitute
messages=[{"role": "user", "content": "Additional message"}]
)
print(response)
```
### Step 3: Direct API Testing
You can also test the wrapper API directly:
```bash
# Test with curl
curl -H "Authorization: Bearer YOUR_BRAINTRUST_TOKEN" \
"http://localhost:8080/beta/litellm_prompt_management?prompt_id=YOUR_PROMPT_ID"
# Health check
curl http://localhost:8080/health
# Service info
curl http://localhost:8080/
```
## API Documentation
Once the server is running, visit:
- Swagger UI: `http://localhost:8080/docs`
- ReDoc: `http://localhost:8080/redoc`
## Braintrust Format Transformation
The wrapper automatically transforms Braintrust's response format:
**Braintrust API Response:**
```json
{
"id": "prompt-123",
"prompt_data": {
"prompt": {
"type": "chat",
"messages": [
{
"role": "system",
"content": "You are a helpful assistant"
}
]
},
"options": {
"model": "gpt-4",
"params": {
"temperature": 0.7,
"max_tokens": 100
}
}
}
}
```
**Transformed to LiteLLM Format:**
```json
{
"prompt_id": "prompt-123",
"prompt_template": [
{
"role": "system",
"content": "You are a helpful assistant"
}
],
"prompt_template_model": "gpt-4",
"prompt_template_optional_params": {
"temperature": 0.7,
"max_tokens": 100
}
}
```
## Supported Parameters
The wrapper automatically maps these Braintrust parameters to LiteLLM:
- `temperature`
- `max_tokens` / `max_completion_tokens`
- `top_p`
- `frequency_penalty`
- `presence_penalty`
- `n`
- `stop`
- `response_format`
- `tool_choice`
- `function_call`
- `tools`
## Variable Substitution
The generic prompt manager supports simple variable substitution:
```python
# In your Braintrust prompt:
# "Hello {name}, welcome to {place}!"
# In your code:
prompt_variables = {
"name": "Alice",
"place": "Wonderland"
}
# Result:
# "Hello Alice, welcome to Wonderland!"
```
Supports both `{variable}` and `{{variable}}` syntax.
## Error Handling
The wrapper provides detailed error messages:
- **401**: Missing or invalid Braintrust API token
- **404**: Prompt not found in Braintrust
- **502**: Failed to connect to Braintrust API
- **500**: Error transforming response
## Production Deployment
For production use:
1. **Use HTTPS**: Deploy behind a reverse proxy with SSL
2. **Authentication**: Add authentication to the wrapper endpoint if needed
3. **Rate Limiting**: Implement rate limiting to prevent abuse
4. **Caching**: Consider caching prompt responses
5. **Monitoring**: Add logging and monitoring
Example with Docker:
```dockerfile
FROM python:3.11-slim
WORKDIR /app
RUN pip install fastapi uvicorn httpx
COPY braintrust_prompt_wrapper_server.py .
ENV PORT=8080
ENV HOST=0.0.0.0
EXPOSE 8080
CMD ["python", "braintrust_prompt_wrapper_server.py"]
```
## Extending to Other Providers
This pattern can be used with any prompt management provider:
1. Create a wrapper server that implements `/beta/litellm_prompt_management`
2. Transform the provider's response to LiteLLM format
3. Use the generic prompt manager to connect
Example providers:
- Langsmith
- PromptLayer
- Humanloop
- Custom internal systems
## Troubleshooting
### "No Braintrust API token provided"
- Set `BRAINTRUST_API_KEY` environment variable
- Or pass token in `Authorization: Bearer TOKEN` header
### "Failed to connect to Braintrust API"
- Check your internet connection
- Verify Braintrust API is accessible
- Check firewall settings
### "Prompt not found"
- Verify the prompt ID exists in Braintrust
- Check that your API token has access to the prompt
## License
This wrapper is part of the LiteLLM project and follows the same license.

@ -59,6 +59,30 @@ To stop the running containers, use the following command:
docker compose down
```
## Hardened / Offline Testing
To ensure changes are safe for non-root, read-only root filesystems and restricted egress, always validate with the hardened compose file:
```bash
docker compose -f docker-compose.yml -f docker-compose.hardened.yml build --no-cache
docker compose -f docker-compose.yml -f docker-compose.hardened.yml up -d
```
This setup:
- Builds from `docker/Dockerfile.non_root` with Prisma engines and Node toolchain baked into the image.
- Runs the proxy as a non-root user with a read-only rootfs and only two writable tmpfs mounts:
- `/app/cache` (Prisma/NPM cache; backing `PRISMA_BINARY_CACHE_DIR`, `NPM_CONFIG_CACHE`, `XDG_CACHE_HOME`)
- `/app/migrations` (Prisma migration workspace; backing `LITELLM_MIGRATION_DIR`)
- Routes all outbound traffic through a local Squid proxy that denies egress, so Prisma migrations must use the cached CLI and engines.
You should also verify offline Prisma behaviour with:
```bash
docker run --rm --network none --entrypoint prisma ghcr.io/berriai/litellm:main-stable --version
```
This command should succeed (showing engine versions) even with `--network none`, confirming that Prisma binaries are available without network access.
## Troubleshooting
- **`build_admin_ui.sh: not found`**: This error can occur if the Docker build context is not set correctly. Ensure that you are running the `docker-compose` command from the root of the project.

# Gemini 3 Flash Day 0 Support
LiteLLM now supports `gemini-3-flash-preview` and all the new API changes along with it.
## What's New
### 1. New Thinking Levels: `thinkingLevel` with MINIMAL & MEDIUM
Gemini 3 Flash introduces granular thinking control with `thinkingLevel` instead of `thinkingBudget`.
- **MINIMAL**: Ultra-lightweight thinking for fast responses
- **MEDIUM**: Balanced thinking for complex reasoning
- **HIGH**: Maximum reasoning depth
LiteLLM automatically maps the OpenAI `reasoning_effort` parameter to Gemini's `thinkingLevel`, so you can use familiar `reasoning_effort` values (`minimal`, `low`, `medium`, `high`) without changing your code!
### 2. Thought Signatures
Like `gemini-3-pro`, this model also includes thought signatures for tool calls. LiteLLM handles signature extraction and embedding internally. [Learn more about thought signatures](../gemini_3/index.md#thought-signatures).
**Edge Case Handling**: If thought signatures are missing in the request, LiteLLM adds a dummy signature ensuring the API call doesn't break
---
## Supported Endpoints
LiteLLM provides **full end-to-end support** for Gemini 3 Flash on:
- ✅ `/v1/chat/completions` - OpenAI-compatible chat completions endpoint
- ✅ `/v1/responses` - OpenAI Responses API endpoint (streaming and non-streaming)
- ✅ [`/v1/messages`](../../docs/anthropic_unified) - Anthropic-compatible messages endpoint
- ✅ `/v1/generateContent` – [Google Gemini API](../../docs/generateContent.md) compatible endpoint
All endpoints support:
- Streaming and non-streaming responses
- Function calling with thought signatures
- Multi-turn conversations
- All Gemini 3-specific features

# A2A Agent Cost Tracking
LiteLLM supports adding custom cost tracking for A2A agents. You can configure:
- **Flat cost per query** - A fixed cost charged for each agent request
- **Cost by input/output tokens** - Variable cost based on token usage
This allows you to track and attribute costs for agent usage across your organization, making it easy to see how much each team or project is spending on agent calls.
## Quick Start
### 1. Navigate to Agents
From the sidebar, click on "Agents" to open the agent management page.
![Navigate to Agents](https://ajeuwbhvhr.cloudimg.io/https://colony-recorder.s3.amazonaws.com/files/2025-12-13/f9ac0752-6936-4dda-b7ed-f536fefcc79a/ascreenshot.jpeg?tl_px=208,326&br_px=2409,1557&force_format=jpeg&q=100&width=1120.0)
### 2. Create a New Agent
Click "+ Add New Agent" to open the creation form. You'll need to provide a few basic details:
- **Agent Name** - A unique identifier for your agent (used in API calls)
- **Display Name** - A human-readable name shown in the UI
![Enter Agent Name](https://ajeuwbhvhr.cloudimg.io/https://colony-recorder.s3.amazonaws.com/files/2025-12-13/f5bacfeb-67a0-4644-a400-b3d50b6b9ce5/ascreenshot.jpeg?tl_px=0,0&br_px=2617,1463&force_format=jpeg&q=100&width=1120.0)
![Enter Display Name](https://ajeuwbhvhr.cloudimg.io/https://colony-recorder.s3.amazonaws.com/files/2025-12-13/6db6422b-fe85-4a8b-aa5c-39319f0d4621/ascreenshot.jpeg?tl_px=0,27&br_px=2617,1490&force_format=jpeg&q=100&width=1120.0)
### 3. Configure Cost Settings
Scroll down and click on "Cost Configuration" to expand the cost settings panel. This is where you define how much to charge for agent usage.

### 3. Select Your Agent
Now pick the agent you just created from the agent dropdown. You should see it listed by its display name.
![Select Agent](https://ajeuwbhvhr.cloudimg.io/https://colony-recorder.s3.amazonaws.com/files/2025-12-13/8c7add70-fe72-48cb-ba33-9f53b989fcad/ascreenshot.jpeg?tl_px=0,150&br_px=2201,1381&force_format=jpeg&q=100&width=1120.0&wat=1&wat_opacity=0.7&wat_gravity=northwest&wat_url=https://colony-recorder.s3.us-west-1.amazonaws.com/images/watermarks/FB923C_standard.png&wat_pad=287,277)
### 4. Send a Test Message
Type a message and hit send. You can use the suggested prompts or write your own.
![Send Message](https://ajeuwbhvhr.cloudimg.io/https://colony-recorder.s3.amazonaws.com/files/2025-12-13/2c16acb1-4016-447e-88e9-c4522e408ea2/ascreenshot.jpeg?tl_px=15,653&br_px=2216,1883&force_format=jpeg&q=100&width=1120.0&wat=1&wat_opacity=0.7&wat_gravity=northwest&wat_url=https://colony-recorder.s3.us-west-1.amazonaws.com/images/watermarks/FB923C_standard.png&wat_pad=524,443)
Once the agent responds, the request is logged with the cost you configured.
![Agent Response](https://ajeuwbhvhr.cloudimg.io/https://colony-recorder.s3.amazonaws.com/files/2025-12-13/2dcf7109-0be4-4d03-8333-ef45759c70c9/ascreenshot.jpeg?tl_px=0,0&br_px=2201,1230&force_format=jpeg&q=100&width=1120.0&wat=1&wat_opacity=0.7&wat_gravity=northwest&wat_url=https://colony-recorder.s3.us-west-1.amazonaws.com/images/watermarks/FB923C_standard.png&wat_pad=494,273)
## Viewing Cost in Logs
Now let's confirm the cost was actually tracked.
### 1. Navigate to Logs
Click "Logs" in the sidebar to see all recent requests.
![Go to Logs](https://ajeuwbhvhr.cloudimg.io/https://colony-recorder.s3.amazonaws.com/files/2025-12-13/c96abf3c-f06a-4401-ada6-04b6e8040453/ascreenshot.jpeg?tl_px=0,118&br_px=2201,1349&force_format=jpeg&q=100&width=1120.0&wat=1&wat_opacity=0.7&wat_gravity=northwest&wat_url=https://colony-recorder.s3.us-west-1.amazonaws.com/images/watermarks/FB923C_standard.png&wat_pad=41,277)
### 2. View Cost Attribution
Find your agent request in the list. You'll see the cost column showing the amount you configured. This cost is now attributed to the API key that made the request, so you can track spend per team or project.
![View Cost in Logs](https://ajeuwbhvhr.cloudimg.io/https://colony-recorder.s3.amazonaws.com/files/2025-12-13/1ae167ec-1a43-48a3-9251-43d4cb3e57f5/ascreenshot.jpeg?tl_px=335,11&br_px=2536,1242&force_format=jpeg&q=100&width=1120.0&wat=1&wat_opacity=0.7&wat_gravity=northwest&wat_url=https://colony-recorder.s3.us-west-1.amazonaws.com/images/watermarks/FB923C_standard.png&wat_pad=524,277)
## View Spend in Usage Page
Navigate to the Agent Usage tab in the Admin UI to view agent-level spend analytics:
### 1. Access Agent Usage
Go to the Usage page in the Admin UI (`PROXY_BASE_URL/ui/?login=success&page=new_usage`) and click on the **Agent Usage** tab.
<Image img={require('../img/agent_usage_ui_navigation.png')} />
### 2. View Agent Analytics
The Agent Usage dashboard provides:
- **Total spend per agent**: View aggregated spend across all agents
- **Daily spend trends**: See how agent spend changes over time
- **Model usage breakdown**: Understand which models each agent uses
- **Activity metrics**: Track requests, tokens, and success rates per agent
<Image img={require('../img/agent_usage_analytics.png')} />
### 3. Filter by Agent
Use the agent filter dropdown to view spend for specific agents:
- Select one or more agent IDs from the dropdown
- View filtered analytics, spend logs, and activity metrics
- Compare spend across different agents
<Image img={require('../img/agent_usage_filter.png')} />
## Cost Configuration Options
You can mix and match these options depending on your pricing model:
| Field | Description |
| ----------------------------- | ----------------------------------------- |
| **Cost Per Query ($)** | Fixed cost charged for each agent request |
| **Input Cost Per Token ($)** | Cost per input token processed |
| **Output Cost Per Token ($)** | Cost per output token generated |
For most use cases, a flat cost per query is simplest. Use token-based pricing if your agent costs vary significantly based on input/output length.

## Comparison with Anthropic Passthrough
LiteLLM provides two ways to count tokens:
| Endpoint | Description | Use Case |
|----------|-------------|----------|
| `/v1/messages/count_tokens` | LiteLLM's Anthropic-compatible endpoint | Works with all supported providers (Anthropic, Vertex AI, Bedrock, etc.) |
| `/anthropic/v1/messages/count_tokens` | [Pass-through to Anthropic API](./pass_through/anthropic_completion.md#example-2-token-counting-api) | Direct Anthropic API access with native headers |
### Pass-through Example
For direct Anthropic API access with full native headers:
```bash
curl --request POST \
--url http://0.0.0.0:4000/anthropic/v1/messages/count_tokens \
--header "x-api-key: $LITELLM_API_KEY" \
--header "anthropic-version: 2023-06-01" \
--header "anthropic-beta: token-counting-2024-11-01" \
--header "content-type: application/json" \
--data '{
"model": "claude-3-5-sonnet-20241022",
"messages": [
{"role": "user", "content": "Hello, world"}
]
}'

For example, if you send `temperature=0.2` to a model that doesn't support the `temperature` parameter, LiteLLM will raise an exception.
**When `drop_params=True` is set**, LiteLLM will drop the unsupported parameter instead of raising an exception. This allows your code to work seamlessly across different providers without having to customize parameters for each one.

**Supported syntax:**
- `field` - Top-level field
- `parent.child` - Nested object field
- `array[*]` - All array elements
- `array[0]` - Specific array index
- `tools[*].input_examples` - Field in all array elements
- `tools[0].metadata.field` - Specific index + nested field
**Example use cases:**
- Remove `input_examples` from tool definitions (Claude Code + AWS Bedrock)
- Drop provider-specific fields from nested structures
- Clean up nested parameters before sending to LLM
## Specify allowed openai params in a request
Tell litellm to allow specific openai params in a request. Use this if you get a `litellm.UnsupportedParamsError` and want to allow a param. LiteLLM will pass the param as is to the model.

| Supported Providers | `openai` |
## LiteLLM AI Gateway
### API (OpenAI SDK)
Use the OpenAI SDK pointed at your LiteLLM Gateway:
```python showLineNumbers title="code_interpreter_gateway.py"
from openai import OpenAI
client = OpenAI(
api_key="sk-1234", # Your LiteLLM API key
base_url="http://localhost:4000"
)
response = client.responses.create(
model="openai/gpt-4o",
tools=[{"type": "code_interpreter"}],
input="Calculate the first 20 fibonacci numbers and plot them"
)
print(response)
```
#### Streaming
```python showLineNumbers title="code_interpreter_streaming.py"
from openai import OpenAI
client = OpenAI(
api_key="sk-1234",
base_url="http://localhost:4000"
)
stream = client.responses.create(
model="openai/gpt-4o",
tools=[{"type": "code_interpreter"}],
input="Generate sample sales data CSV and create a visualization",
stream=True
)
for event in stream:
print(event)
```
#### Get Generated File Content
```python showLineNumbers title="get_file_content_gateway.py"
from openai import OpenAI
client = OpenAI(
api_key="sk-1234",
base_url="http://localhost:4000"
)
# 1. Run code interpreter
response = client.responses.create(
model="openai/gpt-4o",
tools=[{"type": "code_interpreter"}],
input="Create a scatter plot and save as PNG"
)
# 2. Get container_id from response
container_id = response.output[0].container_id
# 3. List files
files = client.containers.files.list(container_id=container_id)
# 4. Download file content
for file in files.data:
content = client.containers.files.content(
container_id=container_id,
file_id=file.id
)
with open(file.filename, "wb") as f:
f.write(content.read())
print(f"Downloaded: {file.filename}")
```
### AI Gateway UI
The LiteLLM Admin UI includes built-in Code Interpreter support.
<Image img={require('../../img/code_interp.png')} />
**Steps:**
1. Go to **Playground** in the LiteLLM UI
2. Select an **OpenAI model** (e.g., `openai/gpt-4o`)
3. Select `/v1/responses` as the endpoint under **Endpoint Type**
4. Toggle **Code Interpreter** in the left panel
5. Send a prompt requesting code execution or file generation
The UI will display:
- Executed Python code (collapsible)
- Generated images inline
- Download links for files (CSVs, etc.)
## LiteLLM Python SDK
### Run Code Interpreter
```python showLineNumbers title="code_interpreter.py"
import litellm
response = litellm.responses(
model="openai/gpt-4o",
input="Generate a bar chart of quarterly sales and save as PNG",
tools=[{"type": "code_interpreter"}]
)
print(response)
```
### Get Generated File Content
After Code Interpreter runs, retrieve the generated files:
```python showLineNumbers title="get_file_content.py"
import litellm
# 1. Run code interpreter
response = litellm.responses(
model="openai/gpt-4o",
input="Create a pie chart of market share and save as PNG",
tools=[{"type": "code_interpreter"}]
)
# 2. Extract container_id from response
container_id = response.output[0].container_id # e.g. "cntr_abc123..."
# 3. List files in container
files = litellm.list_container_files(
container_id=container_id,
custom_llm_provider="openai"
)
# 4. Download each file
for file in files.data:
content = litellm.retrieve_container_file_content(
container_id=container_id,
file_id=file.id,
custom_llm_provider="openai"
)
with open(file.filename, "wb") as f:
f.write(content)
print(f"Downloaded: {file.filename}")
```

## Use MCP tools with `/chat/completions`
:::tip Works with all providers
This flow is **provider-agnostic**: the same MCP tool definition works for _every_ LLM backend behind LiteLLM (OpenAI, Azure OpenAI, Anthropic, Amazon Bedrock, Vertex, self-hosted deployments, etc.).
:::
LiteLLM Proxy also supports MCP-aware tooling on the classic `/v1/chat/completions` endpoint. Provide the MCP tool definition directly in the `tools` array and LiteLLM will fetch and transform the MCP server's tools into OpenAI-compatible function calls. When `require_approval` is set to `"never"`, the proxy automatically executes the returned tool calls and feeds the results back into the model before returning the assistant response.
```bash title="Chat Completions with MCP Tools" showLineNumbers
curl --location '<your-litellm-proxy-base-url>/v1/chat/completions' \
--header 'Content-Type: application/json' \
--header "Authorization: Bearer $LITELLM_API_KEY" \
--data '{
"model": "gpt-4o-mini",
"messages": [
{"role": "user", "content": "Summarize the latest open PR."}
],
"tools": [
{
"type": "mcp",
"server_url": "litellm_proxy/mcp/github",
"server_label": "github_mcp",
"require_approval": "never"
}
]
}'
```
If you omit `require_approval` or set it to any value other than `"never"`, the MCP tool calls are returned to the client so that you can review and execute them manually, matching the upstream OpenAI behavior.
## LiteLLM Proxy - Walk through MCP Gateway
LiteLLM exposes an MCP Gateway for admins to add all their MCP servers to LiteLLM. The key benefits of using LiteLLM Proxy with MCP are:

There are two main approaches to integrate Helicone with LiteLLM:
1. **Callbacks**: Log to Helicone while using any provider
2. **Proxy Mode**: Use Helicone as a proxy for advanced features
1. **As a Provider**: Use Helicone to log requests for [all models supported ](../providers/helicone)
2. **Callbacks**: Log to Helicone while using any provider

The Sumo Logic HTTP Source URL includes the authentication token, so no separate API key is required.
<Tabs>
<TabItem value="python" label="SDK">
```python
litellm.callbacks = ["sumologic"]
```
```python
import litellm
import os
# Sumo Logic HTTP Source URL (includes auth token)
os.environ["SUMOLOGIC_WEBHOOK_URL"] = "https://collectors.sumologic.com/receiver/v1/http/your-token-here"
# LLM API Keys
os.environ['OPENAI_API_KEY'] = ""
# Set sumologic as a callback
litellm.callbacks = ["sumologic"]
# OpenAI call
response = litellm.completion(
model="gpt-3.5-turbo",
messages=[
{"role": "user", "content": "Hi 👋 - I'm testing Sumo Logic integration"}
]
)
```
</TabItem>
<TabItem value="proxy" label="LiteLLM Proxy">
1. Setup config.yaml
```yaml
model_list:
- model_name: gpt-3.5-turbo
litellm_params:
model: openai/gpt-3.5-turbo
api_key: os.environ/OPENAI_API_KEY
litellm_settings:
callbacks: ["sumologic"]
environment_variables:
SUMOLOGIC_WEBHOOK_URL: os.environ/SUMOLOGIC_WEBHOOK_URL
```
2. Start LiteLLM Proxy
```bash
litellm --config /path/to/config.yaml
```
3. Test it!
```bash
curl -L -X POST 'http://0.0.0.0:4000/chat/completions' \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer sk-1234' \
-d '{
"model": "gpt-3.5-turbo",
"messages": [
{
"role": "user",
"content": "Hey, how are you?"
}
]
}'
```
</TabItem>
</Tabs>
## What Data is Logged?
LiteLLM sends the [Standard Logging Payload](https://docs.litellm.ai/docs/proxy/logging_spec) to Sumo Logic, which includes:
- **Request details**: Model, messages, parameters
- **Response details**: Completion text, token usage, latency
- **Metadata**: User ID, custom metadata, timestamps
- **Cost tracking**: Response cost based on token usage
Example payload:
```json
{
"id": "chatcmpl-123",
"call_type": "litellm.completion",
"model": "gpt-3.5-turbo",
"messages": [
{"role": "user", "content": "Hello"}
],
"response": {
"choices": [{
"message": {
"role": "assistant",
"content": "Hi there!"
}
}]
},
"usage": {
"prompt_tokens": 10,
"completion_tokens": 5,
"total_tokens": 15
},
"response_cost": 0.0001,
"start_time": "2024-01-01T00:00:00",
"end_time": "2024-01-01T00:00:01"
}
```
## Advanced Configuration
### Batching Settings
Control how LiteLLM batches logs before sending to Sumo Logic:
<Tabs>
<TabItem value="python" label="SDK">
```python
import litellm
os.environ["SUMOLOGIC_WEBHOOK_URL"] = "https://collectors.sumologic.com/receiver/v1/http/your-token"
litellm.callbacks = ["sumologic"]
# Configure batch settings (optional)
# These are inherited from CustomBatchLogger
# Default batch_size: 100
# Default flush_interval: 60 seconds
```
</TabItem>
<TabItem value="proxy" label="LiteLLM Proxy">
```yaml
litellm_settings:
callbacks: ["sumologic"]
environment_variables:
SUMOLOGIC_WEBHOOK_URL: os.environ/SUMOLOGIC_WEBHOOK_URL
```
</TabItem>
</Tabs>
### Compressed Data
Sumo Logic supports compressed data (gzip or deflate). LiteLLM automatically handles compression when beneficial.
Benefits:
- Reduced network usage
- Faster message delivery
- Lower data transfer costs
### Query Logs in Sumo Logic
Once logs are flowing to Sumo Logic, you can query them using the Sumo Logic Query Language:
```sql
_sourceCategory=litellm
| json "model", "response_cost", "usage.total_tokens" as model, cost, tokens
| sum(cost) by model
```
Example queries:
**Total cost by model:**
```sql
_sourceCategory=litellm
| json "model", "response_cost" as model, cost
| sum(cost) as total_cost by model
| sort by total_cost desc
```
**Average response time:**
```sql
_sourceCategory=litellm
| json "start_time", "end_time" as start, end
| parse regex field=start "(?<start_ms>\d+)"
| parse regex field=end "(?<end_ms>\d+)"
| (end_ms - start_ms) as response_time_ms
| avg(response_time_ms) as avg_response_time
```
**Requests per user:**
```sql
_sourceCategory=litellm
| json "model_parameters.user" as user
| count by user
```
## Authentication
The Sumo Logic HTTP Source URL includes the authentication token, so you only need to set the `SUMOLOGIC_WEBHOOK_URL` environment variable.
**Security Best Practices:**
- Keep your HTTP Source URL private (it contains the auth token)
- Store it in environment variables or secrets management
- Regenerate the URL if it's compromised (in Sumo Logic UI)
- Use separate HTTP Sources for different environments (dev, staging, prod)
## Getting Your Sumo Logic URL
1. Log in to [Sumo Logic](https://www.sumologic.com/)
2. Go to **Manage Data** > **Collection** > **Collection**
3. Click **Add Source** next to a Hosted Collector
4. Select **HTTP Logs & Metrics**
5. Configure the source:
- **Name**: LiteLLM Logs
- **Source Category**: litellm (optional, but helps with queries)
6. Click **Save**
7. Copy the displayed URL - it will look like:
```
https://collectors.sumologic.com/receiver/v1/http/ZaVnC4dhaV39Tn37...
```
## Troubleshooting
### Logs not appearing in Sumo Logic
1. **Verify the URL**: Make sure `SUMOLOGIC_WEBHOOK_URL` is set correctly
2. **Check the HTTP Source**: Ensure it's active in Sumo Logic UI
3. **Wait for batching**: Logs are sent in batches, wait 60 seconds
4. **Check for errors**: Enable debug logging in LiteLLM:
```python
litellm.set_verbose = True
```
### URL Format
The URL must be the complete HTTP Source URL from Sumo Logic:
- ✅ Correct: `https://collectors.sumologic.com/receiver/v1/http/ZaVnC4dhaV39Tn37...`
### No authentication errors
If you get authentication errors, regenerate the HTTP Source URL in Sumo Logic:
1. Go to your HTTP Source in Sumo Logic
2. Click the settings icon
3. Click **Show URL**
4. Click **Regenerate URL**
5. Update your `SUMOLOGIC_WEBHOOK_URL` environment variable

:::note Configuration Required for Batch Cost Tracking
For batch passthrough cost tracking to work properly, you need to define the Anthropic model in your `proxy_config.yaml`:
```yaml
model_list:
- model_name: claude-sonnet-4-5-20250929 # or any alias
litellm_params:
model: anthropic/claude-sonnet-4-5-20250929
api_key: os.environ/ANTHROPIC_API_KEY
```
This ensures the polling mechanism can correctly identify the provider and retrieve batch status for cost calculation.

# Azure AI Foundry Agents
Call Azure AI Foundry Agents in the OpenAI Request/Response format.
| Property | Details |
|----------|---------|
| Description | Azure AI Foundry Agents provides hosted agent runtimes that can execute agentic workflows with foundation models, tools, and code interpreters. |
| Provider Route on LiteLLM | `azure_ai/agents/{AGENT_ID}` |
| Provider Doc | [Azure AI Foundry Agents ↗](https://learn.microsoft.com/en-us/azure/ai-foundry/agents/quickstart) |
## Authentication
Azure AI Foundry Agents require **Azure AD authentication** (not API keys). You can authenticate using:
### Option 1: Service Principal (Recommended for Production)
Set these environment variables:
```bash
export AZURE_TENANT_ID="your-tenant-id"
export AZURE_CLIENT_ID="your-client-id"
export AZURE_CLIENT_SECRET="your-client-secret"
```
LiteLLM will automatically obtain an Azure AD token using these credentials.
### Option 2: Azure AD Token (Manual)
Pass a token directly via `api_key`:
```bash
# Get token via Azure CLI
az account get-access-token --resource "https://ai.azure.com" --query accessToken -o tsv
```
### Required Azure Role
Your Service Principal or user must have the **Azure AI Developer** or **Azure AI User** role on your Azure AI Foundry project.
To assign via Azure CLI:
```bash
az role assignment create \
--assignee-object-id "<service-principal-object-id>" \
--assignee-principal-type "ServicePrincipal" \
--role "Azure AI Developer" \
--scope "/subscriptions/<sub>/resourceGroups/<rg>/providers/Microsoft.CognitiveServices/accounts/<resource>"
```
Or add via **Azure AI Foundry Portal** → Your Project → **Project users** → **+ New user**.
## Quick Start
### Model Format to LiteLLM
To call an Azure AI Foundry Agent through LiteLLM, use the following model format.
Here the `model=azure_ai/agents/` tells LiteLLM to call the Azure AI Foundry Agent Service API.
```shell showLineNumbers title="Model Format to LiteLLM"
azure_ai/agents/{AGENT_ID}
```
**Example:**
- `azure_ai/agents/asst_abc123`
You can find the Agent ID in your Azure AI Foundry portal under Agents.
### LiteLLM Python SDK
```python showLineNumbers title="Basic Agent Completion"
import litellm
# Make a completion request to your Azure AI Foundry Agent
# Uses AZURE_TENANT_ID, AZURE_CLIENT_ID, AZURE_CLIENT_SECRET env vars for auth
response = litellm.completion(
model="azure_ai/agents/asst_abc123",
messages=[
{
"role": "user",
"content": "Explain machine learning in simple terms"
}
],
api_base="https://your-resource.services.ai.azure.com/api/projects/your-project",
)
print(response.choices[0].message.content)
print(f"Usage: {response.usage}")
```
```python showLineNumbers title="Streaming Agent Responses"
import litellm
# Stream responses from your Azure AI Foundry Agent
response = await litellm.acompletion(
model="azure_ai/agents/asst_abc123",
messages=[

## Azure Blob Storage Integration
LiteLLM supports using Azure Blob Storage as a target storage backend for Gemini file uploads. This allows you to store files in Azure Data Lake Storage Gen2 instead of Google's managed storage.
### Step 1: Setup Azure Blob Storage
Configure your Azure Blob Storage account by setting the following environment variables:
**Required Environment Variables:**
- `AZURE_STORAGE_ACCOUNT_NAME` - Your Azure Storage account name
- `AZURE_STORAGE_FILE_SYSTEM` - The container/filesystem name where files will be stored
- `AZURE_STORAGE_ACCOUNT_KEY` - Your account key
### Step 2: Pass Azure Blob Storage as Target Storage
When uploading files, specify `target_storage: "azure_storage"` to use Azure Blob Storage instead of the default storage.
**Supported File Types:**
Azure Blob Storage supports all Gemini-compatible file types:
- **Images**: PNG, JPEG, WEBP
- **Audio**: AAC, FLAC, MP3, MPA, MPEG, MPGA, OPUS, PCM, WAV, WEBM
- **Video**: FLV, MOV, MPEG, MPEGPS, MPG, MP4, WEBM, WMV, 3GPP
- **Documents**: PDF, TXT
> **Note:** Only small files can be sent as inline data because the total request size limit is 20 MB.
### Step 3: Upload Files with Azure Blob Storage for Gemini
<Tabs>
<TabItem value="proxy" label="PROXY">
1. Setup config.yaml

## `/v1/ranking` Models (llama-3.2-nv-rerankqa-1b-v2)
Some Nvidia NIM rerank models use the `/v1/ranking` endpoint instead of the default `/v1/retrieval/{model}/reranking` endpoint.
Use the `ranking/` prefix to force requests to the `/v1/ranking` endpoint:
### LiteLLM Python SDK
```python showLineNumbers title="Force /v1/ranking endpoint with ranking/ prefix"
import litellm
import os
os.environ['NVIDIA_NIM_API_KEY'] = "nvapi-..."
# Use "ranking/" prefix to force /v1/ranking endpoint
response = litellm.rerank(
model="nvidia_nim/ranking/nvidia/llama-3.2-nv-rerankqa-1b-v2",
query="which way did the traveler go?",
documents=[
"two roads diverged in a yellow wood...",
"then took the other, as just as fair...",
"i shall be telling this with a sigh somewhere ages and ages hence..."
],
top_n=3,
truncate="END", # Optional: truncate long text from the end
)
print(response)
```
### LiteLLM Proxy
```yaml showLineNumbers title="config.yaml"
model_list:
- model_name: nvidia-ranking
litellm_params:
model: nvidia_nim/ranking/nvidia/llama-3.2-nv-rerankqa-1b-v2
api_key: os.environ/NVIDIA_NIM_API_KEY
```
```bash title="Request to LiteLLM Proxy"
curl -X POST http://0.0.0.0:4000/rerank \
-H "Authorization: Bearer sk-1234" \
-H "Content-Type: application/json" \
-d '{
"model": "nvidia-ranking",
"query": "which way did the traveler go?",
"documents": [
"two roads diverged in a yellow wood...",
"then took the other, as just as fair..."
],
"top_n": 2
}'
```
### Understanding Model Resolution
**Ranking Endpoint (`/v1/ranking`):**
```
model: nvidia_nim/ranking/nvidia/llama-3.2-nv-rerankqa-1b-v2
└────┬────┘ └──┬──┘ └─────────────┬──────────────────┘
│ │ │
│ │ └────▶ Model name sent to provider
│ │
│ └────────────────────────▶ Tells LiteLLM the request/response and url should be sent to Nvidia NIM /v1/ranking endpoint
│
└─────────────────────────────────▶ Provider prefix
API URL: https://ai.api.nvidia.com/v1/ranking
```
**Visual Flow:**
```
Client Request LiteLLM Provider API
────────────── ──────────── ─────────────
# Default reranking endpoint
model: "nvidia_nim/nvidia/model-name"
1. Extracts model: nvidia/model-name
2. Routes to default endpoint ──────▶ POST /v1/retrieval/nvidia/model-name/reranking
# Forced ranking endpoint
model: "nvidia_nim/ranking/nvidia/model-name"
1. Detects "ranking/" prefix
2. Extracts model: nvidia/model-name
3. Routes to ranking endpoint ──────▶ POST /v1/ranking
Body: {"model": "nvidia/model-name", ...}
```
**When to use each endpoint:**
| Endpoint | Model Prefix | Use Case |
|----------|--------------|----------|
| `/v1/retrieval/{model}/reranking` | `nvidia_nim/<model>` | Default for most rerank models |
| `/v1/ranking` | `nvidia_nim/ranking/<model>` | For models like `nvidia/llama-3.2-nv-rerankqa-1b-v2` that require this endpoint |
:::tip
Check the [Nvidia NIM model deployment page](https://build.nvidia.com/nvidia/llama-3_2-nv-rerankqa-1b-v2/deploy) to see which endpoint your model requires.

Call Pydantic AI Agents via LiteLLM's A2A Gateway.
| Property | Details |
|----------|---------|
| Description | Pydantic AI agents with native A2A support via the `to_a2a()` method. LiteLLM provides fake streaming support for agents that don't natively stream. |
| Provider Route on LiteLLM | A2A Gateway |
| Supported Endpoints | `/v1/a2a/message/send` |
| Provider Doc | [Pydantic AI Agents ↗](https://ai.pydantic.dev/agents/) |
## LiteLLM A2A Gateway
All Pydantic AI agents need to be exposed as A2A agents using the `to_a2a()` method. Once your agent server is running, you can add it to the LiteLLM Gateway.
### 1. Setup Pydantic AI Agent Server
LiteLLM requires Pydantic AI agents to follow the [A2A (Agent-to-Agent) protocol](https://github.com/google/A2A). Pydantic AI has native A2A support via the `to_a2a()` method, which exposes your agent as an A2A-compliant server.
#### Install Dependencies
```bash
pip install pydantic-ai fasta2a uvicorn
```
#### Create Agent
```python title="agent.py"
from pydantic_ai import Agent
agent = Agent('openai:gpt-4o-mini', instructions='Be helpful!')
@agent.tool_plain
def get_weather(city: str) -> str:
"""Get weather for a city."""
return f"Weather in {city}: Sunny, 72°F"
@agent.tool_plain
def calculator(expression: str) -> str:
"""Evaluate a math expression."""
return str(eval(expression))
# Native A2A server - Pydantic AI handles it automatically
app = agent.to_a2a()
```
#### Run Server
```bash
uvicorn agent:app --host 0.0.0.0 --port 9999
```
Server runs at `http://localhost:9999`
### 2. Navigate to Agents
From the sidebar, click "Agents" to open the agent management page, then click "+ Add New Agent".
### 3. Select Pydantic AI Agent Type
Click "A2A Standard" to see available agent types, then select "Pydantic AI".

# Stability AI
https://stability.ai/
## Overview
| Property | Details |
|-------|-------|
| Description | Stability AI creates open AI models for image, video, audio, and 3D generation. Known for Stable Diffusion. |
| Provider Route on LiteLLM | `stability/` |
| Link to Provider Doc | [Stability AI API ↗](https://platform.stability.ai/docs/api-reference) |
| Supported Operations | [`/images/generations`](#image-generation) |
LiteLLM supports Stability AI Image Generation calls via the Stability AI REST API (not via Bedrock).
## API Key
```python
# env variable
os.environ['STABILITY_API_KEY'] = "your-api-key"
```
Get your API key from the [Stability AI Platform](https://platform.stability.ai/).
## Image Generation
### Usage - LiteLLM Python SDK
```python showLineNumbers
from litellm import image_generation
import os
os.environ['STABILITY_API_KEY'] = "your-api-key"
# Stability AI image generation call
response = image_generation(
model="stability/sd3.5-large",
prompt="A beautiful sunset over a calm ocean",
)
print(response)
```
### Usage - LiteLLM Proxy Server
#### 1. Setup config.yaml
```yaml showLineNumbers
model_list:
- model_name: sd3
litellm_params:
model: stability/sd3.5-large
api_key: os.environ/STABILITY_API_KEY
model_info:
mode: image_generation
general_settings:
master_key: sk-1234
```
#### 2. Start the proxy
```bash showLineNumbers
litellm --config config.yaml
# RUNNING on http://0.0.0.0:4000
```
#### 3. Test it
```bash showLineNumbers
curl --location 'http://0.0.0.0:4000/v1/images/generations' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer sk-1234' \
--data '{
"model": "sd3",
"prompt": "A beautiful sunset over a calm ocean"
}'
```
### Advanced Usage - With Additional Parameters
```python showLineNumbers
from litellm import image_generation
import os
os.environ['STABILITY_API_KEY'] = "your-api-key"
response = image_generation(
model="stability/sd3.5-large",
prompt="A beautiful sunset over a calm ocean",
size="1792x1024", # Maps to aspect_ratio 16:9
negative_prompt="blurry, low quality", # Stability-specific
seed=12345, # For reproducibility
)
print(response)
```
### Supported Parameters
Stability AI supports the following OpenAI-compatible parameters:
| Parameter | Type | Description | Example |
|-----------|------|-------------|---------|
| `size` | string | Image dimensions (mapped to aspect_ratio) | `"1024x1024"` |
| `n` | integer | Number of images (note: Stability returns 1 per request) | `1` |
| `response_format` | string | Format of response (`b64_json` only for Stability) | `"b64_json"` |
### Size to Aspect Ratio Mapping
The `size` parameter is automatically mapped to Stability's `aspect_ratio`:
| OpenAI Size | Stability Aspect Ratio |
|-------------|----------------------|
| `1024x1024` | `1:1` |
| `1792x1024` | `16:9` |
| `1024x1792` | `9:16` |
| `512x512` | `1:1` |
| `256x256` | `1:1` |
### Using Stability-Specific Parameters
You can pass parameters that are specific to Stability AI directly in your request:
```python showLineNumbers
from litellm import image_generation
import os
os.environ['STABILITY_API_KEY'] = "your-api-key"
response = image_generation(
model="stability/sd3.5-large",
prompt="A beautiful sunset over a calm ocean",
# Stability-specific parameters
negative_prompt="blurry, watermark, text",
aspect_ratio="16:9", # Use directly instead of size
seed=42,
output_format="png", # png, jpeg, or webp
)
print(response)
```
### Supported Image Generation Models
| Model Name | Function Call | Description |
|------------|---------------|-------------|
| sd3 | `image_generation(model="stability/sd3", ...)` | Stable Diffusion 3 |
| sd3-large | `image_generation(model="stability/sd3-large", ...)` | SD3 Large |
| sd3-large-turbo | `image_generation(model="stability/sd3-large-turbo", ...)` | SD3 Large Turbo (faster) |
| sd3-medium | `image_generation(model="stability/sd3-medium", ...)` | SD3 Medium |
| sd3.5-large | `image_generation(model="stability/sd3.5-large", ...)` | SD 3.5 Large (recommended) |
| sd3.5-large-turbo | `image_generation(model="stability/sd3.5-large-turbo", ...)` | SD 3.5 Large Turbo |
| sd3.5-medium | `image_generation(model="stability/sd3.5-medium", ...)` | SD 3.5 Medium |
| stable-image-ultra | `image_generation(model="stability/stable-image-ultra", ...)` | Stable Image Ultra |
| stable-image-core | `image_generation(model="stability/stable-image-core", ...)` | Stable Image Core |
For more details on available models and features, see: https://platform.stability.ai/docs/api-reference
## Response Format
Stability AI returns images in base64 format. The response is OpenAI-compatible:
```python
{
"created": 1234567890,
"data": [
{
"b64_json": "iVBORw0KGgo..." # Base64 encoded image
}
]
}
```
## Comparing with Bedrock
LiteLLM supports Stability AI models via two routes:
| Route | Provider | Use Case |
|-------|----------|----------|
| `stability/` | Stability AI Direct API | Direct access, all latest models |
| `bedrock/stability.*` | AWS Bedrock | AWS integration, enterprise features |
Use `stability/` for direct API access. Use `bedrock/stability.*` if you're already using AWS Bedrock.

# vLLM - Batch + Files API
LiteLLM supports vLLM's Batch and Files API for processing large volumes of requests asynchronously.
| Feature | Supported |
|---------|-----------|
| `/v1/files` | ✅ |
| `/v1/batches` | ✅ |
| Cost Tracking | ✅ |
## Quick Start
### 1. Setup config.yaml
Define your vLLM model in `config.yaml`. LiteLLM uses the model name to route batch requests to the correct vLLM server.
```yaml
model_list:
- model_name: my-vllm-model
litellm_params:
model: hosted_vllm/meta-llama/Llama-2-7b-chat-hf
api_base: http://localhost:8000 # your vLLM server
```
### 2. Start LiteLLM Proxy
```bash
litellm --config /path/to/config.yaml
```
### 3. Create Batch File
Create a JSONL file with your batch requests:
```jsonl
{"custom_id": "request-1", "method": "POST", "url": "/v1/chat/completions", "body": {"model": "my-vllm-model", "messages": [{"role": "user", "content": "Hello!"}]}}
{"custom_id": "request-2", "method": "POST", "url": "/v1/chat/completions", "body": {"model": "my-vllm-model", "messages": [{"role": "user", "content": "How are you?"}]}}
```
### 4. Upload File & Create Batch
:::tip Model Routing
LiteLLM needs to know which model (and therefore which vLLM server) to use for batch operations. Specify the model using the `x-litellm-model` header when uploading files. LiteLLM will encode this model info into the file ID, so subsequent batch operations automatically route to the correct server.
See [Multi-Account / Model-Based Routing](../batches#multi-account--model-based-routing) for more details.

## Supported Operations
| Operation | Endpoint | Method |
|-----------|----------|--------|
| Upload file | `/v1/files` | POST |
| List files | `/v1/files` | GET |
| Retrieve file | `/v1/files/{file_id}` | GET |
| Delete file | `/v1/files/{file_id}` | DELETE |
| Get file content | `/v1/files/{file_id}/content` | GET |
| Create batch | `/v1/batches` | POST |
| List batches | `/v1/batches` | GET |
| Retrieve batch | `/v1/batches/{batch_id}` | GET |
| Cancel batch | `/v1/batches/{batch_id}/cancel` | POST |
## Environment Variables
```bash
# Set vLLM server endpoint
export HOSTED_VLLM_API_BASE="http://localhost:8000"
# Optional: API key if your vLLM server requires authentication
export HOSTED_VLLM_API_KEY="your-api-key"
```
## How Model Routing Works
When you upload a file with `x-litellm-model: my-vllm-model`, LiteLLM:
1. Encodes the model name into the returned file ID
2. Uses this encoded model info to automatically route subsequent batch operations to the correct vLLM server
3. No need to specify the model again when creating batches or retrieving results
This enables multi-tenant batch processing where different teams can use different vLLM deployments through the same LiteLLM proxy.

## Rerank
Voyage AI provides reranking models to improve search relevance by reordering documents based on their relevance to a query.
### Quick Start
```python
from litellm import rerank
import os
os.environ["VOYAGE_API_KEY"] = "your-api-key"
response = rerank(
model="voyage/rerank-2.5",
query="What is the capital of France?",
documents=[
"Paris is the capital of France.",
"London is the capital of England.",
"Berlin is the capital of Germany.",
],
top_n=3,
)
print(response)
```
### Async Usage
```python
from litellm import arerank
import os
import asyncio
os.environ["VOYAGE_API_KEY"] = "your-api-key"
async def main():
response = await arerank(
model="voyage/rerank-2.5-lite",
query="Best programming language for beginners?",
documents=[
"Python is great for beginners due to simple syntax.",
"JavaScript runs in browsers and is versatile.",
"Rust has a steep learning curve but is very safe.",
],
top_n=2,
)
print(response)
asyncio.run(main())
```
### LiteLLM Proxy Usage
Add to your `config.yaml`:
```yaml
model_list:
- model_name: rerank-2.5
litellm_params:
model: voyage/rerank-2.5
api_key: os.environ/VOYAGE_API_KEY
- model_name: rerank-2.5-lite
litellm_params:
model: voyage/rerank-2.5-lite
api_key: os.environ/VOYAGE_API_KEY
```
Test with curl:
```bash
curl http://localhost:4000/rerank \
-H "Authorization: Bearer sk-1234" \
-H "Content-Type: application/json" \
-d '{
"model": "rerank-2.5",
"query": "What is the capital of France?",
"documents": [
"Paris is the capital of France.",
"London is the capital of England.",
"Berlin is the capital of Germany."
],
"top_n": 3
}'
```
### Supported Rerank Models
| Model | Context Length | Description | Price/M Tokens |
|-------|----------------|-------------|----------------|
| rerank-2.5 | 32K | Best quality, multilingual, instruction-following | $0.05 |
| rerank-2.5-lite | 32K | Optimized for latency and cost | $0.02 |

```
**Assigning User Roles via SSO**
Use `GENERIC_USER_ROLE_ATTRIBUTE` to specify which attribute in the SSO token contains the user's role. The role value must be one of the following supported LiteLLM roles:
- `proxy_admin` - Admin over the platform
- `proxy_admin_viewer` - Can login, view all keys, view all spend (read-only)
- `internal_user` - Can login, view/create/delete their own keys, view their spend
- `internal_user_view_only` - Can login, view their own keys, view their own spend
Nested attribute paths are supported (e.g., `claims.role` or `attributes.litellm_role`).
- Set Redirect URI, if your provider requires it
- Set a redirect url = `<your proxy base url>/sso/callback`

title: /cursor/chat/completions - Cursor Endpoint
description: Accept Responses API input from Cursor and return OpenAI Chat Completions output
---
LiteLLM provides a Cursor-specific endpoint to make Cursor IDE work seamlessly with the LiteLLM Proxy when using BYOK + custom `base_url`.
- Accepts Requests in OpenAI Responses API input format (Cursor sends this)
- Returns Responses in OpenAI Chat Completions format (Cursor expects this)
- Supports streaming and non‑streaming
## Endpoint
- Path: `/cursor/chat/completions`
- Auth: Standard LiteLLM Proxy auth (`Authorization: Bearer <key>`)
- Behavior: Internally routes to LiteLLM `/responses` flow and transforms output to Chat Completions
## Why this exists
When setting up Cursor with BYOK against a custom `base_url`, Cursor sends requests to the Chat Completions endpoint but in the OpenAI Responses API input shape. Without translation, Cursor won’t display streamed output. This endpoint bridges the formats:
- Input: Responses API (`input`, tool calls, etc.)
- Output: Chat Completions (`choices`, `delta`, `finish_reason`, etc.)
## Usage
### Non-streaming
```bash
curl -X POST https://litellm-internal/cursor/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer sk-1234" \
-d '{
"model": "gpt-4o",
"input": [{"role": "user", "content": "Hello"}]
}'
```
Example response (shape):
```json
{
"id": "chatcmpl-123",
"object": "chat.completion",
"created": 1733333333,
"model": "gpt-4o",
"choices": [
{
"index": 0,
"message": {
"role": "assistant",
"content": "Hello! How can I help you?"
},
"finish_reason": "stop"
}
],
"usage": {
"prompt_tokens": 10,
"completion_tokens": 8,
"total_tokens": 18
}
}
```
### Streaming
```bash
curl -N -X POST https://litellm-internal/cursor/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer sk-1234" \
-d '{
"model": "gpt-4o",
"input": [{"role": "user", "content": "Hello"}],
"stream": true
}'
```
- Server-Sent Events (SSE)
- Emits `chat.completion.chunk` deltas (`choices[].delta`) and ends with `data: [DONE]`
## Configuration
### Base URL Setup
**Important**: When configuring Cursor IDE to use this endpoint, you must include `/cursor` in the base URL.
Cursor automatically appends `/chat/completions` to the base URL you provide. To ensure requests go to `/cursor/chat/completions`, configure your base URL in Cursor as:
```
Base URL: https://litellm-internal/cursor
```
This way, when Cursor appends `/chat/completions`, the full path becomes `/cursor/chat/completions`, which is the correct endpoint.
**Example**: If your LiteLLM Proxy is running at `https://litellm-internal`, set the base URL in Cursor to `https://litellm-internal/cursor` (not just `https://litellm-internal`).
### General Setup
No special configuration is required beyond your normal LiteLLM Proxy setup. Ensure that:
- Your `config.yaml` includes the models you want to call via this endpoint
- Your Cursor project uses your LiteLLM Proxy `base_url` (with `/cursor` included) and a valid API key
## Notes
- This endpoint is intended specifically for Cursor’s request/response expectations. Other clients should continue to use `/v1/chat/completions` or `/v1/responses` as appropriate.

Below this threshold, generous mode allows priority borrowing from unused capacity. Above this threshold, strict mode enforces normalized priority limits.

| `post_call` | After response | Full conversation | Scan output for policy violations, leaked secrets, or IPI |
When using `during_call` with `on_flagged_action: block` or `on_flagged_action: passthrough`:
- **The LLM call runs in parallel** with the guardrail check using `asyncio.gather`
- **LLM tokens are still consumed** even if the guardrail detects a violation
- The guardrail exception prevents the response from reaching the user, but **does not cancel the running LLM task**
- This means you pay full LLM costs while returning an error/passthrough message to the user
**Recommendation:** For cost-sensitive applications, use `pre_call` and `post_call` instead of `during_call` for blocking or passthrough modes. Reserve `during_call` for `monitor` mode where you want low-latency logging without impacting the user experience.

# HiddenLayer Guardrails
LiteLLM ships with a native integration for [HiddenLayer](https://hiddenlayer.com/). The proxy sends every request/response to HiddenLayer’s `/detection/v1/interactions` endpoint so you can block or redact unsafe content before it reaches your users.
## Quick Start
### 1. Create a HiddenLayer project & API credentials
**SaaS (`*.hiddenlayer.ai`)**
1. Sign in to the HiddenLayer console and create (or select) a project with policies enabled.
2. Generate a **Client ID** and **Client Secret** for the project.
3. Export them as environment variables in your LiteLLM deployment:
```shell
export HIDDENLAYER_CLIENT_ID="hl_client_id"
export HIDDENLAYER_CLIENT_SECRET="hl_client_secret"
# Optional overrides
# export HIDDENLAYER_API_BASE="https://api.eu.hiddenlayer.ai"
# export HL_AUTH_URL="https://auth.hiddenlayer.ai"
```
**Self-hosted HiddenLayer**
If you run HiddenLayer on-prem, just expose the endpoint and set:
```shell
export HIDDENLAYER_API_BASE="https://hiddenlayer.your-domain.com"

### 2. Add the hiddenlayer guardrail to `config.yaml`
```yaml showLineNumbers title="litellm config.yaml"
model_list:
- model_name: gpt-4o-mini
litellm_params:
model: openai/gpt-4o-mini
api_key: os.environ/OPENAI_API_KEY
guardrails:
- guardrail_name: "hiddenlayer-guardrails"
litellm_params:
guardrail: hiddenlayer
mode: ["pre_call", "post_call", "during_call"] # run at multiple stages
default_on: true
api_base: os.environ/HIDDENLAYER_API_BASE
api_id: os.environ/HIDDENLAYER_CLIENT_ID # only needed for SaaS
api_key: os.environ/HIDDENLAYER_CLIENT_SECRET # only needed for SaaS
```
#### Supported values for `mode`
- `pre_call` Run **before** the LLM call on **input**.
- `post_call` Run **after** the LLM call on **input & output**.
- `during_call` Run **during** the LLM call on **input**. LiteLLM sends the request to the model and HiddenLayer in parallel. The response waits for the guardrail result before returning.
### 3. Start LiteLLM Gateway
```shell
litellm --config config.yaml --detailed_debug
```
### 4. Test a request
You can tag requests with `hl-project-id` (maps to the HiddenLayer project) and `hl-requester-id` (auditing metadata). LiteLLM forwards both headers to your detector.

api_key: os.environ/HIDDENLAYER_CLIENT_SECRET # optional
api_base: os.environ/HIDDENLAYER_API_BASE # optional
default_on: true
```
### Required parameters
- **`guardrail`**: Must be set to `hiddenlayer` so LiteLLM loads the HiddenLayer hook.
### Optional parameters
- **`api_base`**: HiddenLayer REST endpoint. Defaults to `https://api.hiddenlayer.ai`, but point it at your self-hosted instance if you have one.
- **`auth_url`**: Authentication url for hiddenlayer. Defaults to `https;//auth.hiddenlayer.ai`.
- **`mode`**: Control when the guardrail runs (`pre_call`, `post_call`, `during_call`).
- **`default_on`**: Automatically attach the guardrail to every request unless the client opts out.
- **`hl-project-id` header**: Routes scans to a specific HiddenLayer project.
- **`hl-requester-id` header**: Sets `metadata.requester_id` for auditing.
## Environment variables
```shell
# SaaS
export HIDDENLAYER_CLIENT_ID="hl_client_id"
export HIDDENLAYER_CLIENT_SECRET="hl_client_secret"
# Shared (SaaS or self-hosted)
export HIDDENLAYER_API_BASE="https://api.hiddenlayer.ai"
```
Set only the variables you need, self-hosted installs can leave the client ID/secret unset and just configure `HIDDENLAYER_API_BASE`.

# Onyx Security
## Quick Start
### 1. Create a new Onyx Guard policy
Go to [Onyx's platform](https://app.onyx.security) and create a new AI Guard policy.
After creating the policy, copy the generated API key.
### 2. Define Guardrails on your LiteLLM config.yaml
Define your guardrails under the `guardrails` section:
```yaml showLineNumbers title="litellm config.yaml"
model_list:
- model_name: gpt-4o-mini
litellm_params:
model: openai/gpt-4o-mini
api_key: os.environ/OPENAI_API_KEY
guardrails:
- guardrail_name: "onyx-ai-guard"
litellm_params:
guardrail: onyx
mode: ["pre_call", "post_call", "during_call"] # Run at multiple stages
default_on: true
api_base: os.environ/ONYX_API_BASE
api_key: os.environ/ONYX_API_KEY
```
#### Supported values for `mode`
- `pre_call` Run **before** LLM call, on **input**
- `post_call` Run **after** LLM call, on **input & output**
- `during_call` Run **during** LLM call, on **input**. Same as `pre_call` but runs in parallel with the LLM call. Response not returned until guardrail check completes
### 3. Start LiteLLM Gateway
```shell
litellm --config config.yaml --detailed_debug

The guardrail is **fail-closed** by default - if the PANW API is unavailable, requests are blocked to ensure no unscanned content reaches your LLM. This provides maximum security.
:::
### Fail-Open Configuration
By default, the PANW guardrail operates in **fail-closed** mode for maximum security. If the PANW API is unavailable (timeout, rate limit, network error), requests are blocked. You can configure **fail-open** mode for high-availability scenarios where service continuity is critical.
```yaml
guardrails:
- guardrail_name: "panw-high-availability"
litellm_params:
guardrail: panw_prisma_airs
api_key: os.environ/PANW_PRISMA_AIRS_API_KEY
profile_name: "production"
fallback_on_error: "allow" # Enable fail-open mode
timeout: 5.0 # Shorter timeout for fail-open
```
**Configuration Options:**
| Parameter | Value | Behavior |
|-----------|-------|----------|
| `fallback_on_error` | `"block"` (default) | **Fail-closed**: Block requests when API unavailable (maximum security) |
| `fallback_on_error` | `"allow"` | **Fail-open**: Allow requests when API unavailable (high availability) |
| `timeout` | `1.0` - `60.0` | API call timeout in seconds (default: `10.0`) |
**Error Handling Matrix:**
| Error Type | `fallback_on_error="block"` | `fallback_on_error="allow"` |
|------------|----------------------------|----------------------------|
| 401 Unauthorized | Block (500) | Block (500) ⚠️ |
| 403 Forbidden | Block (500) | Block (500) ⚠️ |
| Profile Error | Block (500) | Block (500) ⚠️ |
| 429 Rate Limit | Block (500) | Allow (`:unscanned`) |
| Timeout | Block (500) | Allow (`:unscanned`) |
| Network Error | Block (500) | Allow (`:unscanned`) |
| 5xx Server Error | Block (500) | Allow (`:unscanned`) |
| Content Blocked | Block (400) | Block (400) |
⚠️ = Always blocks regardless of fail-open setting
:::warning Security Trade-Off
Enabling `fallback_on_error="allow"` reduces security in exchange for availability. Requests may proceed **without scanning** when the PANW API is unavailable. Use only when:
- Service availability is more critical than security scanning
- You have other security controls in place
- You monitor the `:unscanned` header for audit trails
**Authentication and configuration errors (401, 403, invalid profile) always block** - only transient errors (429, timeout, network) trigger fail-open behavior.
:::
**Observability:**
When fail-open is triggered, the response includes a special header for tracking:
```
X-LiteLLM-Applied-Guardrails: panw-airs:unscanned
```
This allows you to:
- Track which requests bypassed scanning
- Alert on unscanned request volumes
- Audit compliance requirements

## Entity Type Configuration
## Entity Types, Detection Confidence Score Threshold, and Scope Configuration
You can configure specific entity types for PII detection and decide how to handle each entity type (mask or block).
- **Entity Types**
- You can configure specific entity types for PII detection and decide how to handle each entity type (mask or block).
- **Detection Confidence Score Threshold**
- You can also provide an optional confidence score threshold at which detections will be passed to the anonymizer. Entities without an entry in `presidio_score_thresholds` keep all detections (no minimum score).
- **Scope**
- Use the optional `presidio_filter_scope` to choose where checks run:
### Configure Entity Types in config.yaml
- `input`: only user → model content is scanned
- `output`: only model → user content is scanned
- `both` (default): scan both directions
**What about `output_parse_pii`?**
This flag only un-masks tokens back to the originals after the model call; it does not run Presidio detection on outputs. Use `presidio_filter_scope: output` (or `both`) when you want Presidio to actively scan and mask the model’s response before it reaches the user.
**When to pick input vs output:**
- `input`: Protect upstream providers; strip PII before it leaves your boundary.
- `output`: Catch PII the model might generate or leak back to users.
- `both`: End-to-end protection in both directions.

Pillar Security supports three execution modes for comprehensive protection:
Pillar Security supports five execution modes for comprehensive protection:
| Mode | When It Runs | What It Protects | Use Case
|------|-------------|------------------|----------
| **`pre_call`** | Before LLM call | User input only | Block malicious prompts, prevent prompt injection
| **`during_call`** | Parallel with LLM call | User input only | Input monitoring with lower latency
| **`post_call`** | After LLM response | Full conversation context | Output filtering, PII detection in responses
| **`pre_mcp_call`** | Before MCP tool call | MCP tool inputs | Validate and sanitize MCP tool call arguments

#### Mask
Automatically sanitizes sensitive content (PII, secrets, etc.) in your messages before sending them to the LLM:
```yaml
on_flagged_action: "mask"
```
When masking is enabled, sensitive information is automatically replaced with masked versions, allowing requests to proceed safely without exposing sensitive data to the LLM.
**Response Headers:**
You can opt in to receiving detection details in response headers by configuring `include_scanners: true` and/or `include_evidence: true`. When enabled, these headers are included for **every request**—not just flagged ones—enabling comprehensive metrics, false positive analysis, and threat investigation.
- **`x-pillar-flagged`**: Boolean string indicating Pillar's blocking recommendation (`"true"` or `"false"`)
- **`x-pillar-scanners`**: URL-encoded JSON object showing scanner categories (e.g., `%7B%22jailbreak%22%3Atrue%7D`) — requires `include_scanners: true`
- **`x-pillar-evidence`**: URL-encoded JSON array of detection evidence (may contain items even when `flagged` is `false`) — requires `include_evidence: true`
- **`x-pillar-session-id`**: URL-encoded session ID for correlation and investigation
:::info Understanding `flagged` vs Scanner Results
The `flagged` field is Pillar's **policy-level blocking recommendation**, which may differ from individual scanner results:
- **`flagged: true`** → Pillar recommends blocking based on your configured policies
- **`flagged: false`** → Pillar does not recommend blocking, but individual scanners may still detect content
For example, the `toxic_language` scanner might detect profanity (`scanners.toxic_language: true`) while `flagged` remains `false` if your Pillar policy doesn't block on toxic language alone. This allows you to:
- Monitor threats without blocking users
- Build metrics on detection rates vs block rates
- Analyze false positive rates by comparing scanner results to user feedback
:::
The `x-pillar-scanners`, `x-pillar-evidence`, and `x-pillar-session-id` headers use URL encoding (percent-encoding) to convert JSON data into an ASCII-safe format. This is necessary because HTTP headers only support ISO-8859-1 characters and cannot contain raw JSON special characters (`{`, `"`, `:`) or Unicode text. To read these headers, first URL-decode the value, then parse it as JSON.
LiteLLM truncates the `x-pillar-evidence` header to a maximum of 8 KB per header to avoid proxy limits. Note that most proxies and servers also enforce a total header size limit of approximately 32 KB across all headers combined. When truncation occurs, each affected evidence item includes an `"evidence_truncated": true` flag and the metadata contains `pillar_evidence_truncated: true`.
**Example Response Headers (URL-encoded):**
```http
x-pillar-flagged: true
x-pillar-session-id: abc-123-def-456
x-pillar-scanners: %7B%22jailbreak%22%3Atrue%2C%22prompt_injection%22%3Afalse%2C%22toxic_language%22%3Afalse%7D
x-pillar-evidence: %5B%7B%22category%22%3A%22prompt_injection%22%2C%22evidence%22%3A%22Ignore%20previous%20instructions%22%7D%5D
```
**After Decoding:**
```json
// x-pillar-scanners
{"jailbreak": true, "prompt_injection": false, "toxic_language": false}
// x-pillar-evidence
[{"category": "prompt_injection", "evidence": "Ignore previous instructions"}]
```
**Decoding Example (Python):**
```python
from urllib.parse import unquote
import json
# Step 1: URL-decode the header value (converts %7B to {, %22 to ", etc.)
# Step 2: Parse the resulting JSON string
scanners = json.loads(unquote(response.headers["x-pillar-scanners"]))
evidence = json.loads(unquote(response.headers["x-pillar-evidence"]))
# Session ID is a plain string, so only URL-decode is needed (no JSON parsing)
session_id = unquote(response.headers["x-pillar-session-id"])
```
:::tip
LiteLLM mirrors the encoded values onto `metadata["pillar_response_headers"]` so you can inspect exactly what was returned. When truncation occurs, it sets `metadata["pillar_evidence_truncated"]` to `true` and marks affected evidence items with `"evidence_truncated": true`. Evidence text is shortened with a `...[truncated]` suffix, and entire evidence entries may be removed if necessary to stay under the 8 KB header limit. Check these flags to determine if full evidence details are available in your logs.

This allows your application to:
- Track threats without blocking legitimate users
- Implement custom handling logic based on threat types
- Build analytics and alerting on security events
- Correlate threats across requests using session IDs

**Quick takeaways**
- Every request still runs *all* Pillar scanners; these options only change what comes back.
- Choose richer responses when you need audit trails, lighter responses when latency or cost matters.
- Blocking is controlled by LiteLLM’s `on_flagged_action` configuration—Pillar headers do not change block/monitor behaviour.
- Actions (block/monitor/mask) are controlled by LiteLLM's `on_flagged_action` configuration—Pillar headers are automatically set based on your config.
- When blocking (`on_flagged_action: "block"`), the `include_scanners` and `include_evidence` settings control what details are included in the exception response.
Pillar Security executes the full scanner suite on each call. The settings below tune the Protect response headers LiteLLM sends, letting you balance fidelity, retention, and latency.

Notice that `x-pillar-flagged: false` but `safety: true` in the scanners. This is because `flagged` represents Pillar's policy-level blocking recommendation, while individual scanners report their own detections.
```python
from urllib.parse import unquote

scanners = json.loads(unquote(response.headers["x-pillar-scanners"]))
evidence = json.loads(unquote(response.headers["x-pillar-evidence"]))

# Scanner detected safety issue, but policy didn't flag for blocking
print(f"Flagged for blocking: {flagged}") # False
print(f"Safety issue detected: {scanners.get('safety')}") # True
print(f"Evidence: {evidence}")

**Note:** In monitor mode, scanner results and evidence are included in response headers for every request, allowing you to build metrics and analyze detection patterns. The `flagged` field indicates whether Pillar's policy recommends blocking—your application can use the detailed scanner data for custom alerting, analytics, or false positive analysis.

## Deployment Ordering (Priority)
Set `order` in `litellm_params` to prioritize deployments. Lower values = higher priority. When multiple deployments share the same `order`, the routing strategy picks among them.
```yaml
model_list:
- model_name: gpt-4
litellm_params:
model: azure/gpt-4-primary
api_key: os.environ/AZURE_API_KEY
order: 1 # 👈 Highest priority - always tried first

api_key: os.environ/AZURE_API_KEY_2
order: 2 # 👈 Used when order=1 is unavailable
```
If `order=1` deployment is unavailable (e.g., rate-limited), the router falls back to `order=2` deployments.

## Onboarding Prompts via config.yaml
You can onboard and initialize prompts directly in your `config.yaml` file. This allows you to:
- Load prompts at proxy startup
- Manage prompts as code alongside your proxy configuration
- Use any supported prompt integration (dotprompt, Langfuse, BitBucket, GitLab, custom)
### Basic Structure
Add a `prompts` field to your config.yaml:
```yaml
model_list:
- model_name: gpt-4
litellm_params:
model: openai/gpt-4
api_key: os.environ/OPENAI_API_KEY
prompts:
- prompt_id: "my_prompt_id"
litellm_params:
prompt_id: "my_prompt_id"
prompt_integration: "dotprompt" # or langfuse, bitbucket, gitlab, custom
# integration-specific parameters below
```
### Understanding `prompt_integration`
The `prompt_integration` field determines where and how prompts are loaded:
- **`dotprompt`**: Load from local `.prompt` files or inline content
- **`langfuse`**: Fetch prompts from Langfuse prompt management
- **`bitbucket`**: Load from BitBucket repository `.prompt` files (team-based access control)
- **`gitlab`**: Load from GitLab repository `.prompt` files (team-based access control)
- **`custom`**: Use your own custom prompt management implementation
Each integration has its own configuration parameters and access control mechanisms.
### Supported Integrations
<Tabs>
<TabItem value="dotprompt" label="DotPrompt (File-based)">
**Option 1: Using a prompt directory**
```yaml
prompts:
- prompt_id: "hello"
litellm_params:
prompt_id: "hello"
prompt_integration: "dotprompt"
prompt_directory: "./prompts" # Directory containing .prompt files
litellm_settings:
global_prompt_directory: "./prompts" # Global setting for all dotprompt integrations
```
**Option 2: Using inline prompt data**
```yaml
prompts:
- prompt_id: "my_inline_prompt"
litellm_params:
prompt_id: "my_inline_prompt"
prompt_integration: "dotprompt"
prompt_data:
my_inline_prompt:
content: "Hello {{name}}! How can I help you with {{topic}}?"
metadata:
model: "gpt-4"
temperature: 0.7
max_tokens: 150
```
**Option 3: Using dotprompt_content for single prompts**
```yaml
prompts:
- prompt_id: "simple_prompt"
litellm_params:
prompt_id: "simple_prompt"
prompt_integration: "dotprompt"
dotprompt_content: |

### Complete Example
Here's a complete example showing multiple prompts with different integrations:
```yaml
model_list:
- model_name: gpt-4
litellm_params:
model: openai/gpt-4
api_key: os.environ/OPENAI_API_KEY
prompts:
# File-based dotprompt
- prompt_id: "coding_assistant"
litellm_params:
prompt_id: "coding_assistant"
prompt_integration: "dotprompt"
prompt_directory: "./prompts"
# Inline dotprompt
- prompt_id: "simple_chat"
litellm_params:
prompt_id: "simple_chat"
prompt_integration: "dotprompt"
prompt_data:
simple_chat:
content: "You are a {{personality}} assistant. User: {{message}}"
metadata:
model: "gpt-4"
temperature: 0.8
# Langfuse prompt
- prompt_id: "langfuse_chat"
litellm_params:
prompt_id: "langfuse_chat"
prompt_integration: "langfuse"
langfuse_public_key: "os.environ/LANGFUSE_PUBLIC_KEY"
langfuse_secret_key: "os.environ/LANGFUSE_SECRET_KEY"
litellm_settings:
global_prompt_directory: "./prompts"
```
### How It Works
1. **At Startup**: When the proxy starts, it reads the `prompts` field from `config.yaml`
2. **Initialization**: Each prompt is initialized based on its `prompt_integration` type
3. **In-Memory Storage**: Prompts are stored in the `IN_MEMORY_PROMPT_REGISTRY`
4. **Access**: Use these prompts via the `/v1/chat/completions` endpoint with `prompt_id` in the request
### Using Config-Loaded Prompts
After loading prompts via config.yaml, use them in your API requests:
```bash
curl -L -X POST 'http://0.0.0.0:4000/v1/chat/completions' \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer sk-1234' \
-d '{
"model": "gpt-4",
"prompt_id": "coding_assistant",
"prompt_variables": {
"language": "python",
"task": "create a web scraper"
}
}'
```
### Prompt Schema Reference
Each prompt in the `prompts` list requires:
- **`prompt_id`** (string, required): Unique identifier for the prompt
- **`litellm_params`** (object, required): Configuration for the prompt
- **`prompt_id`** (string, required): Must match the top-level prompt_id
- **`prompt_integration`** (string, required): One of: `dotprompt`, `langfuse`, `bitbucket`, `gitlab`, `custom`
- Additional integration-specific parameters (see tabs above)
- **`prompt_info`** (object, optional): Metadata about the prompt
- **`prompt_type`** (string): Defaults to `"config"` for config-loaded prompts
### Notes
- Config-loaded prompts have `prompt_type: "config"` and **cannot be updated** via the API
- To update config prompts, modify your `config.yaml` and restart the proxy
- For dynamic prompts that can be updated via API, use the `/prompts` endpoints instead
- All supported integrations work with config-loaded prompts

# Control Public & Private Routes
:::info
Requires a LiteLLM Enterprise License. [Get a free trial](https://calendly.com/d/4mp-gd3-k5k/litellm-1-1-onboarding-chat).
:::
Control which routes require authentication and which routes are publicly accessible.
## Route Types
| Route Type | Requires Auth | Description |
|------------|---------------|-------------|
| `public_routes` | No | Routes accessible without any authentication |
| `admin_only_routes` | Yes (Admin only) | Routes only accessible by [Proxy Admin](./self_serve#available-roles) |
| `allowed_routes` | Yes | Routes exposed on the proxy. If not set, all routes are exposed |
## Quick Start
### Make Routes Public
Allow specific routes to be accessed without authentication:
```yaml
general_settings:
master_key: sk-1234
public_routes: ["LiteLLMRoutes.public_routes", "/spend/calculate"]
```
### Restrict Routes to Admin Only
Restrict certain routes to only be accessible by Proxy Admin:
```yaml
general_settings:
master_key: sk-1234
admin_only_routes: ["/key/generate", "/key/delete"]
```
### Limit Available Routes
Only expose specific routes on the proxy:
```yaml
general_settings:
master_key: sk-1234
allowed_routes: ["/chat/completions", "/embeddings", "LiteLLMRoutes.public_routes"]
```
## Usage Examples
### Define Public, Admin Only, and Allowed Routes
```yaml
general_settings:
master_key: sk-1234
public_routes: ["LiteLLMRoutes.public_routes", "/spend/calculate"]
admin_only_routes: ["/key/generate"]
allowed_routes: ["/chat/completions", "/spend/calculate", "LiteLLMRoutes.public_routes"]
```
`LiteLLMRoutes.public_routes` is an ENUM corresponding to the default public routes on LiteLLM. [View the source](https://github.com/BerriAI/litellm/blob/main/litellm/proxy/_types.py).
### Testing

"type": "auth_error",
"param": "None",

}
}
```
</TabItem>
</Tabs>
## Advanced: Wildcard Patterns
Use wildcard patterns to match multiple routes at once.
### Syntax
| Pattern | Description | Example |
|---------|-------------|---------|
| `/path/*` | Matches any route starting with `/path/` | `/api/*` matches `/api/users`, `/api/users/123` |
### Examples
#### Make All Routes Under a Path Public
```yaml
general_settings:
master_key: sk-1234
public_routes:
- "LiteLLMRoutes.public_routes"
- "/api/v1/*" # All routes under /api/v1/
- "/health/*" # All health check routes
```
#### Restrict Admin Routes with Wildcards
```yaml
general_settings:
master_key: sk-1234
admin_only_routes:
- "/admin/*" # All admin routes
- "/internal/*" # All internal routes
```
### Testing Wildcard Routes
**Config:**
```yaml
general_settings:
master_key: sk-1234
public_routes:
- "/public/*"
```
**Test:**
```shell
# This works without auth (matches /public/*)
curl http://localhost:4000/public/status
# This also works without auth (matches /public/*)
curl http://localhost:4000/public/health/detailed
# This requires auth (doesn't match /public/*)
curl http://localhost:4000/private/data
```

# Custom Callback
### Step 1 - Create your custom `litellm` callback class
We use `litellm.integrations.custom_logger` for this, **more details about litellm custom callbacks [here](https://docs.litellm.ai/docs/observability/custom_callback)**
Define your custom callback class in a python file.
```python
from litellm.integrations.custom_logger import CustomLogger
import litellm
import logging
# This file includes the custom callbacks for LiteLLM Proxy
# Once defined, these can be passed in proxy_config.yaml
class MyCustomHandler(CustomLogger):
def log_pre_api_call(self, model, messages, kwargs):
print(f"Pre-API Call")
async def async_log_success_event(self, kwargs, response_obj, start_time, end_time):
try:
# init logging config
logging.basicConfig(
filename='cost.log',
level=logging.INFO,
format='%(asctime)s - %(message)s',
datefmt='%Y-%m-%d %H:%M:%S'
)
response_cost: Optional[float] = kwargs.get("response_cost", None)
print("regular response_cost", response_cost)
logging.info(f"Model {response_obj.model} Cost: ${response_cost:.8f}")
except:
pass
proxy_handler_instance = MyCustomHandler()
# Set litellm.callbacks = [proxy_handler_instance] on the proxy
# need to set litellm.callbacks = [proxy_handler_instance] # on the proxy
```
### Step 2 - Pass your custom callback class in `config.yaml`
We pass the custom callback class defined in **Step1** to the config.yaml.
Set `callbacks` to `python_filename.logger_instance_name`
In the config below, we pass
- python_filename: `custom_callbacks.py`
- logger_instance_name: `proxy_handler_instance`. This is defined in Step 1
`callbacks: custom_callbacks.proxy_handler_instance`
```yaml
model_list:
- model_name: gpt-3.5-turbo
litellm_params:
model: gpt-3.5-turbo
litellm_settings:

```shell
litellm --config proxy_config.yaml
```
```shell
curl --location 'http://0.0.0.0:4000/chat/completions' \
--header 'Authorization: Bearer sk-1234' \
--data ' {
"model": "gpt-3.5-turbo",
"messages": [

### Select Team via Request Header
When a JWT token contains multiple teams (via `team_ids_jwt_field`), you can explicitly select which team to use for a request by passing the `x-litellm-team-id` header.
```bash
curl -X POST 'http://0.0.0.0:4000/v1/chat/completions' \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer <your-jwt-token>' \
-H 'x-litellm-team-id: team_id_2' \
-d '{
"model": "gpt-4",
"messages": [{"role": "user", "content": "Hello"}]
}'
```
**Validation:**
- The team ID in the header must exist in the JWT's `team_ids_jwt_field` list or match `team_id_jwt_field`
- If an invalid team is specified, a 403 error is returned
- If no header is provided, LiteLLM auto-selects the first team with access to the requested model

Here's how to use `thinking` blocks by Anthropic with tool calling.
### Important: OpenAI-Compatible API Limitations
:::warning Compatibility Notice
Anthropic extended thinking with tool calling is **not fully compatible** with OpenAI-compatible API clients. This is due to fundamental architectural differences between how OpenAI and Anthropic handle reasoning in multi-turn conversations.
:::
When using Anthropic models with `thinking` enabled and tool calling, you **must include `thinking_blocks`** from the previous assistant response when sending tool results back. Failure to do so will result in a `400 Bad Request` error.
**OpenAI vs Anthropic Architecture:**
| Provider | API Architecture | Reasoning Storage | Multi-turn Handling |
|----------|------------------|-------------------|---------------------|
| **OpenAI** (o1, o3) | Responses API (Stateful) | Server-side | Server stores reasoning internally; client sends `previous_response_id` |
| **Anthropic** (Claude) | Messages API (Stateless) | Client-side | Client must store and resend `thinking_blocks` with every request |
1. OpenAI's Chat Completions spec has **no field** for `thinking_blocks`
2. OpenAI-compatible clients (LibreChat, Open WebUI, Vercel AI SDK, etc.) **ignore** the `thinking_blocks` field in responses
3. When these clients reconstruct the assistant message for the next turn, the thinking blocks are lost
4. Anthropic rejects the request because the assistant message doesn't start with a thinking block
:::tip LiteLLM supports thinking_blocks
LiteLLM's `completion()` API **does support** sending `thinking_blocks` in assistant messages. If you're using LiteLLM directly (not through an OpenAI-compatible client), you can preserve and resend `thinking_blocks` and everything will work correctly.
:::
**Solutions:**
1. **Use LiteLLM's built-in workaround** (recommended): Set `litellm.modify_params = True` and LiteLLM will automatically handle this incompatibility by dropping the `thinking` param when `thinking_blocks` are missing (see below)
2. **For client developers**: Explicitly handle and resend the `thinking_blocks` field (see example below)
3. **Disable extended thinking** when using tools with OpenAI-compatible clients that don't support `thinking_blocks`
4. **Use Anthropic's native API** directly instead of OpenAI-compatible endpoints
### LiteLLM Built-in Workaround
LiteLLM can automatically handle this incompatibility when `modify_params=True` is set. If the client sends a request with `thinking` enabled but the assistant message with `tool_calls` is missing `thinking_blocks`, LiteLLM will automatically drop the `thinking` param for that turn to avoid the error.

thinking:

```
</TabItem>
</Tabs>
:::info
When `modify_params=True` and LiteLLM drops the `thinking` param, the model will **not** use extended thinking for that specific turn. The conversation will continue normally, but without reasoning for that response.
:::
**Correct way to include `thinking_blocks`:**
```python
# After receiving a response with tool_calls, include thinking_blocks when sending back:
assistant_message = {
"role": "assistant",
"content": response.choices[0].message.content,
"tool_calls": [...],
"thinking_blocks": response.choices[0].message.thinking_blocks # ← Required!
}
