+## What's New
+
+### 1. New Thinking Levels: `thinkingLevel` with MINIMAL & MEDIUM
+
+Gemini 3.1 Pro introduces support for **medium** thinking level
+
+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!
+
+---
+## Supported Endpoints
+
+LiteLLM provides **full end-to-end support** for Gemini 3.1 Pro 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
+- Conversion of provider specific thinking related param to thinkingLevel
+

+### Proxy: Always Include Streaming Usage
+
+When using the LiteLLM Proxy, you can configure it to automatically include usage information in all streaming responses, even if the client doesn't send `stream_options={"include_usage": True}`.
+
+#### Configuration
+
+Add the following to your config.yaml:
+
+```yaml
+general_settings:
+  always_include_stream_usage: true
+```
+
+Alternatively, configure it through the UI:
+
+1. Navigate to the LiteLLM Proxy UI
+2. Go to `Settings` >  `Router Settings` > `General`
+3. Find the `always_include_stream_usage` setting
+4. Toggle it to `true`
+5. Click `Update` to save
+
+#### How it works
+
+When `always_include_stream_usage` is enabled:
+- All streaming requests will automatically have `stream_options={"include_usage": True}` added
+- Clients will receive usage information in the final chunk, even if they didn't explicitly request it
+- If a client already provides `stream_options`, `include_usage: True` will be added without overwriting other options
+- Non-streaming requests are not affected
+
+#### Example
+
+With this setting enabled, a simple streaming request like:
+
+```bash
+curl -X POST http://localhost:4000/v1/chat/completions \
+  -H "Authorization: Bearer sk-1234" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "gpt-4o",
+    "messages": [{"role": "user", "content": "Hello!"}],
+    "stream": true
+  }'
+```
+
+Will automatically receive usage information in the response, without needing to explicitly include `stream_options`.

 In this example, when a client makes a request with the `X-GITHUB_PERSONAL_ACCESS_TOKEN` header, the proxy forwards that value into the stdio process as the `GITHUB_PERSONAL_ACCESS_TOKEN` environment variable.
 
+## Control MCP Access for End Users
+
+Control which MCP servers end users of your AI application can access (e.g. users of an internal chat UI). Pass the customer ID in the `x-litellm-end-user-id` header to:
+- Enforce object permissions (limit which MCP servers they can access)
+- Apply customer-specific budgets
+- Track spend per customer

-## Setting Customer Budgets 
+## Setting Customer Object Permissions
+
+Control which resources (MCP servers, vector stores, agents) a customer can access.
+
+### What are Object Permissions?
+
+Object permissions allow you to restrict customer access to specific:
+- **MCP Servers**: Limit which MCP servers the customer can call
+- **MCP Access Groups**: Assign customers to predefined groups of MCP servers
+- **MCP Tool Permissions**: Granular control over which tools within an MCP server the customer can use
+- **Vector Stores**: Control which vector stores the customer can query
+- **Agents**: Restrict which agents the customer can interact with
+- **Agent Access Groups**: Assign customers to predefined groups of agents
+
+### Creating a Customer with Object Permissions
+
+```bash showLineNumbers title="Create customer with object permissions"
+curl -L -X POST 'http://localhost:4000/customer/new' \
+-H 'Authorization: Bearer sk-1234' \
+-H 'Content-Type: application/json' \

+      "agents": ["agent_1"],
+      "agent_access_groups": ["basic_agents"]
+    }
+  }'
+```
+
+**Parameters:**
+- `mcp_servers` (Optional[List[str]]): List of allowed MCP server IDs
+- `mcp_access_groups` (Optional[List[str]]): List of MCP access group names
+- `mcp_tool_permissions` (Optional[Dict[str, List[str]]]): Map of server ID to allowed tool names
+- `vector_stores` (Optional[List[str]]): List of allowed vector store IDs
+- `agents` (Optional[List[str]]): List of allowed agent IDs
+- `agent_access_groups` (Optional[List[str]]): List of agent access group names
+
+**Note:** If `object_permission` is `null` or `{}`, the customer has no object-level restrictions.

+### Viewing Customer Object Permissions
+
+When you query customer info, object permissions are included in the response:
+
+```bash showLineNumbers title="Get customer info with object permissions"
+curl -X GET 'http://0.0.0.0:4000/customer/info?end_user_id=user_1' \
+    -H 'Authorization: Bearer sk-1234'
+```
+
+**Response:**
+```json showLineNumbers title="Response with object permissions"
+{
+  "user_id": "user_1",
+  "blocked": false,
+  "alias": "John Doe",
+  "spend": 0.0,

+```
+
+### Use Cases
+
+**1. Tiered Access Control**
+Create different permission tiers for your customers:
+
+```bash showLineNumbers title="Free tier customer"
+# Free tier - limited access
+curl -L -X POST 'http://localhost:4000/customer/new' \
+-H 'Authorization: Bearer sk-1234' \

+      "agent_access_groups": ["basic_agents"]
+    }
+  }'
+```
+
+```bash showLineNumbers title="Premium tier customer"
+# Premium tier - full access
+curl -L -X POST 'http://localhost:4000/customer/new' \
+-H 'Authorization: Bearer sk-1234' \

+      "agents": ["agent_1", "agent_2", "agent_3"]
+    }
+  }'
+```
+
+**2. Department-Specific Access**
+Restrict customers to resources relevant to their department:
+
+```bash showLineNumbers title="Sales team customer"
+curl -L -X POST 'http://localhost:4000/customer/new' \
+-H 'Authorization: Bearer sk-1234' \

+      "agents": ["sales_assistant"],
+      "vector_stores": ["sales_knowledge_base"]
+    }
+  }'
+```
+
+**3. Tool-Level Restrictions**
+Grant access to specific tools within an MCP server:
+
+```bash showLineNumbers title="Limited tool access"
+curl -L -X POST 'http://localhost:4000/customer/new' \
+-H 'Authorization: Bearer sk-1234' \
+-H 'Content-Type: application/json' \

+### Default Query Parameters
+
+Pass-through endpoints support default query parameters that are automatically added to every request. This is useful for API versioning, format specifications, authentication tokens, or any default configuration.
+
+#### How It Works
+
+**Parameter Precedence (highest to lowest priority):**
+1. **Client-provided parameters** (in the request URL)
+2. **URL parameters** (from the target URL)
+3. **Default parameters** (from configuration)
+
+#### Example Configuration
+
+```yaml
+general_settings:
+  pass_through_endpoints:
+    - path: "/api/v1"
+      target: "https://external-api.com/service?timeout=60"  # URL has timeout=60
+      default_query_params:
+        version: "v1"          # Always add version=v1
+        format: "json"         # Default format=json (can be overridden)
+        auth_level: "basic"    # Always add auth_level=basic
+```
+
+#### Request Examples
+
+**Client Request:** `GET /api/v1/users`
+**Actual Backend Call:** `https://external-api.com/service?version=v1&format=json&auth_level=basic&timeout=60`
+
+**Client Request:** `GET /api/v1/users?format=xml&custom=value`
+**Actual Backend Call:** `https://external-api.com/service?version=v1&auth_level=basic&timeout=60&format=xml&custom=value`
+- Client `format=xml` overrides default `format=json`
+- Default `version=v1` and `auth_level=basic` are preserved
+- URL `timeout=60` is preserved
+- Client `custom=value` is added
+
+#### Use Cases
+
+- **API Versioning**: Always send `version=v2` to maintain compatibility
+- **Authentication**: Add authentication tokens like `api_key=default_key`
+- **Format Control**: Default to `format=json` but allow client override
+- **Rate Limiting**: Set `rate_limit=standard` as default
+- **Feature Flags**: Enable `experimental=false` by default
+
+---
+
+You can configure different target URLs for the same path using different HTTP methods. This is useful when different backends handle different operations:
+
+<Image 
+  img={require('../../img/passthrough_method_setup.png')}
+  style={{width: '60%', display: 'block', margin: '2rem auto'}}
+/>
+
+```yaml
+general_settings:
+  pass_through_endpoints:
+    # GET requests to /azure/kb go to read API
+    - path: "/azure/kb"
+      target: "https://read-api.example.com/knowledge-base"
+      methods: ["GET"]
+      headers:
+        Authorization: "bearer os.environ/READ_API_KEY"
+    
+    # POST requests to /azure/kb go to write API
+    - path: "/azure/kb"
+      target: "https://write-api.example.com/knowledge-base"
+      methods: ["POST"]
+      headers:
+        Authorization: "bearer os.environ/WRITE_API_KEY"
+    
+    # PUT requests to /azure/kb go to update API
+    - path: "/azure/kb"
+      target: "https://update-api.example.com/knowledge-base"
+      methods: ["PUT"]
+      headers:
+        Authorization: "bearer os.environ/UPDATE_API_KEY"
+```
+
+**Key Points:**
+- If `methods` is not specified, the endpoint supports all HTTP methods (GET, POST, PUT, DELETE, PATCH)
+- Multiple endpoints can share the same path as long as they have different methods
+- You can specify multiple methods for a single endpoint: `methods: ["GET", "POST"]`
+- This allows you to route to different backends based on the operation type
+
+---
+
 ## Advanced: Custom Adapters
 
 For complex integrations (like Anthropic/Bedrock clients), you can create custom adapters that translate between different API schemas.

See [OpenAI Compaction guide](https://developers.openai.com/api/docs/guides/compaction) for details.
 
+> **Note:** You can use openai `context_management` format with Anthropic models via LiteLLM via responses API. LiteLLM will automatically translate this format for Anthropic and handle context management for you.
+
 For explicit control over when compaction runs, use the standalone compact endpoint (`POST /v1/responses/compact`) instead.

+# Latency Overhead Troubleshooting
+
+Use this guide when you see unexpected latency overhead between LiteLLM proxy and the LLM provider.
+
+## Quick Checklist
+
+1. **Collect the `x-litellm-overhead-duration-ms` response header** — this tells you LiteLLM's total overhead on every request. Start here.
+2. **Is DEBUG logging enabled?** This is the #1 cause of latency with large payloads.
+3. **Are you sending large base64 payloads?** (images, PDFs) — see [Large Payload Overhead](#large-payload-overhead).
+4. **Enable detailed timing headers** to pinpoint where time is spent.
+
+## Diagnostic Headers
+
+### `x-litellm-overhead-duration-ms` (always on)
+
+Every response from LiteLLM includes this header. It shows the total latency overhead in milliseconds added by LiteLLM proxy (i.e. total response time minus the LLM API call time). Collect this on every request to understand your baseline overhead.
+
+```bash
+curl -s -D - http://localhost:4000/v1/chat/completions \
+  -H "Authorization: Bearer sk-..." \
+  -d '{"model": "gpt-4o", "messages": [{"role": "user", "content": "hi"}]}' \
+  2>&1 | grep x-litellm-overhead-duration-ms
+```
+
+### `x-litellm-callback-duration-ms` (always on)
+
+Shows time spent building callback/logging payloads (ms). If this is high (>100ms), your payloads may be too large for efficient logging.
+
+```bash
+curl -s -D - http://localhost:4000/v1/chat/completions \
+  -H "Authorization: Bearer sk-..." \
+  -d '{"model": "gpt-4o", "messages": [{"role": "user", "content": "hi"}]}' \
+  2>&1 | grep x-litellm
+```
+
+### Detailed Timing Breakdown (opt-in)
+
+Set `LITELLM_DETAILED_TIMING=true` to get per-phase timing in response headers:
+
+| Header | What it measures |
+|--------|-----------------|
+| `x-litellm-timing-pre-processing-ms` | Auth, routing, request processing (before LLM call) |
+| `x-litellm-timing-llm-api-ms` | Actual LLM API call duration |
+| `x-litellm-timing-post-processing-ms` | Response processing (after LLM returns) |
+| `x-litellm-timing-message-copy-ms` | Message copy time in logging layer |
+
+```bash
+# Enable detailed timing
+export LITELLM_DETAILED_TIMING=true
+```
+
+## Large Payload Overhead
+
+When sending large payloads (>1MB, e.g. base64-encoded images/PDFs), three things can add overhead:
+
+### 1. DEBUG Logging (most common)
+
+When `LITELLM_LOG=DEBUG` or `set_verbose=True` is enabled, every request payload is serialized with `json.dumps(indent=4)` synchronously. For a 2MB+ payload, this alone can take **2-5 seconds**.
+
+**Fix:** Don't use DEBUG logging in production. Use `INFO` level instead:
+
+```bash
+export LITELLM_LOG=INFO
+```
+
+If you need DEBUG logging but have large payloads, you can increase the size threshold for full payload logging:
+
+```bash
+# Only fully serialize payloads under 100KB for DEBUG logs (default)
+export MAX_PAYLOAD_SIZE_FOR_DEBUG_LOG=102400
+```
+
+### 2. Base64 in Logging Payloads
+
+Callback payloads (sent to Langfuse, etc.) include message content. Large base64 strings are automatically truncated to size placeholders in logging payloads.
+
+You can control the truncation threshold:
+
+```bash
+# Max base64 characters before truncation (default: 64)
+export MAX_BASE64_LENGTH_FOR_LOGGING=64
+```
+
+## Environment Variables Reference
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `LITELLM_DETAILED_TIMING` | `false` | Enable per-phase timing headers |
+| `MAX_PAYLOAD_SIZE_FOR_DEBUG_LOG` | `102400` | Max payload bytes for full DEBUG serialization |
+| `MAX_BASE64_LENGTH_FOR_LOGGING` | `64` | Max base64 chars before truncation in logging |
