+# MLflow
+
+## What is MLflow?
+
+**MLflow** is an end-to-end open source MLOps platform for [experiment tracking](https://www.mlflow.org/docs/latest/tracking.html), [model management](https://www.mlflow.org/docs/latest/models.html), [evaluation](https://www.mlflow.org/docs/latest/llms/llm-evaluate/index.html), [observability (tracing)](https://www.mlflow.org/docs/latest/llms/tracing/index.html), and [deployment](https://www.mlflow.org/docs/latest/deployment/index.html). MLflow empowers teams to collaboratively develop and refine LLM applications efficiently.
+
+MLflow’s integration with LiteLLM supports advanced observability compatible with OpenTelemetry.
+
+
+<Image img={require('../../img/mlflow_tracing.png')} />
+
+
+## Getting Started
+
+Install MLflow:
+
+```shell
+pip install mlflow
+```
+
+To enable LiteLLM tracing:
+
+```python
+import mlflow
+
+mlflow.litellm.autolog()
+
+# Alternative, you can set the callback manually in LiteLLM
+# litellm.callbacks = ["mlflow"]
+```
+
+Since MLflow is open-source, no sign-up or API key is needed to log traces!
+
+```
+import litellm
+import os
+
+# Set your LLM provider's API key
+os.environ["OPENAI_API_KEY"] = ""
+
+# Call LiteLLM as usual
+response = litellm.completion(
+    model="gpt-4o-mini",
+    messages=[
+      {"role": "user", "content": "Hi 👋 - i'm openai"}
+    ]
+)
+```
+
+Open the MLflow UI and go to the `Traces` tab to view logged traces:
+
+```bash
+mlflow ui
+```
+
+## Exporting Traces to OpenTelemetry collectors
+
+MLflow traces are compatible with OpenTelemetry. You can export traces to any OpenTelemetry collector (e.g., Jaeger, Zipkin, Datadog, New Relic) by setting the endpoint URL in the environment variables.
+
+```
+# Set the endpoint of the OpenTelemetry Collector
+os.environ["OTEL_EXPORTER_OTLP_TRACES_ENDPOINT"] = "http://localhost:4317/v1/traces"
+# Optionally, set the service name to group traces
+os.environ["OTEL_SERVICE_NAME"] = "<your-service-name>"
+```
+
+See [MLflow documentation](https://mlflow.org/docs/latest/llms/tracing/index.html#using-opentelemetry-collector-for-exporting-traces) for more details.
+
+## Combine LiteLLM Trace with Your Application Trace
+
+LiteLLM is often part of larger LLM applications, such as agentic models. MLflow Tracing allows you to instrument custom Python code, which can then be combined with LiteLLM traces.
+
+```python
+import litellm
+import mlflow
+from mlflow.entities import SpanType
+
+# Enable LiteLLM tracing
+mlflow.litellm.autolog()
+
+
+class CustomAgent:
+    # Use @mlflow.trace to instrument Python functions.
+    @mlflow.trace(span_type=SpanType.AGENT)
+    def run(self, query: str):
+        # do something
+
+        while i < self.max_turns:
+            response = litellm.completion(
+                model="gpt-4o-mini",
+                messages=messages,
+            )
+
+            action = self.get_action(response)
+            ...
+
+    @mlflow.trace
+    def get_action(llm_response):
+        ...
+```
+
+This approach generates a unified trace, combining your custom Python code with LiteLLM calls.
+
+
+## Support
+
+* For advanced usage and integrations of tracing, visit the [MLflow Tracing documentation](https://mlflow.org/docs/latest/llms/tracing/index.html).
+* For any question or issue with this integration, please [submit an issue](https://github.com/mlflow/mlflow/issues/new/choose) on our [Github](https://github.com/mlflow/mlflow) repository!

+# Anthropic `/v1/messages`
+
+Pass-through endpoints for Anthropic - call provider-specific endpoint, in native format (no translation).
+
+Just replace `https://api.anthropic.com` with `LITELLM_PROXY_BASE_URL/anthropic` 🚀
+
+#### **Example Usage**
+```bash
+curl --request POST \
+  --url http://0.0.0.0:4000/anthropic/v1/messages \
+  --header 'accept: application/json' \
+  --header 'content-type: application/json' \
+  --header "Authorization: bearer sk-anything" \
+  --data '{
+        "model": "claude-3-5-sonnet-20241022",
+        "max_tokens": 1024,
+        "messages": [
+            {"role": "user", "content": "Hello, world"}
+        ]
+    }'
+```
+
+Supports **ALL** Anthropic Endpoints (including streaming).
+
+[**See All Anthropic Endpoints**](https://docs.anthropic.com/en/api/messages)
+
+## Quick Start
+
+Let's call the Anthropic [`/messages` endpoint](https://docs.anthropic.com/en/api/messages)
+
+1. Add Anthropic API Key to your environment 
+
+```bash
+export ANTHROPIC_API_KEY=""
+```
+
+2. Start LiteLLM Proxy 
+
+```bash
+litellm
+
+# RUNNING on http://0.0.0.0:4000
+```
+
+3. Test it! 
+
+Let's call the Anthropic /messages endpoint
+
+```bash
+curl http://0.0.0.0:4000/anthropic/v1/messages \
+     --header "x-api-key: $LITELLM_API_KEY" \
+     --header "anthropic-version: 2023-06-01" \
+     --header "content-type: application/json" \
+     --data \
+    '{
+        "model": "claude-3-5-sonnet-20241022",
+        "max_tokens": 1024,
+        "messages": [
+            {"role": "user", "content": "Hello, world"}
+        ]
+    }'
+```
+
+
+## Examples
+
+Anything after `http://0.0.0.0:4000/anthropic` is treated as a provider-specific route, and handled accordingly.
+
+Key Changes: 
+
+| **Original Endpoint**                                | **Replace With**                  |
+|------------------------------------------------------|-----------------------------------|
+| `https://api.anthropic.com`          | `http://0.0.0.0:4000/anthropic` (LITELLM_PROXY_BASE_URL="http://0.0.0.0:4000")      |
+| `bearer $ANTHROPIC_API_KEY`                                 | `bearer anything` (use `bearer LITELLM_VIRTUAL_KEY` if Virtual Keys are setup on proxy)                    |
+

+## Advanced - Use with Virtual Keys 
+
+Pre-requisites
+- [Setup proxy with DB](../proxy/virtual_keys.md#setup)
+
+Use this, to avoid giving developers the raw Anthropic API key, but still letting them use Anthropic endpoints.
+
+### Usage
+
+1. Setup environment
+
+```bash
+export DATABASE_URL=""
+export LITELLM_MASTER_KEY=""
+export COHERE_API_KEY=""
+```
+
+```bash
+litellm
+
+# RUNNING on http://0.0.0.0:4000
+```
+
+2. Generate virtual key 
+
+```bash
+curl -X POST 'http://0.0.0.0:4000/key/generate' \
+-H 'Authorization: Bearer sk-1234' \
+-H 'Content-Type: application/json' \
+-d '{}'
+```
+
+Expected Response 
+
+```bash
+{
+    ...
+    "key": "sk-1234ewknldferwedojwojw"
+}
+```
+
+3. Test it! 
+
+
+```bash
+curl --request POST \
+  --url http://0.0.0.0:4000/anthropic/v1/messages \
+  --header 'accept: application/json' \
+  --header 'content-type: application/json' \
+  --header "Authorization: bearer sk-1234ewknldferwedojwojw" \
+  --data '{
+    "model": "claude-3-5-sonnet-20241022",
+    "max_tokens": 1024,
+    "messages": [
+        {"role": "user", "content": "Hello, world"}
+    ]
+  }'
+```
