+## Adding Agents to Flows
+
+Agents can be seamlessly integrated into your flows, providing a lightweight alternative to full Crews when you need simpler, focused task execution. Here's an example of how to use an Agent within a flow to perform market research:
+
+```python
+import asyncio
+from typing import Any, Dict, List
+
+from crewai_tools import SerperDevTool
+from pydantic import BaseModel, Field
+
+from crewai.agent import Agent
+from crewai.flow.flow import Flow, listen, start

+    competitors: List[str] = Field(description="Major competitors in the space")
+
+
+# Define flow state

+    product: str = ""
+    analysis: MarketAnalysis | None = None
+

+# Create a flow class

+    def initialize_research(self) -> Dict[str, Any]:

+        analyst = Agent(
+            role="Market Research Analyst",
+            goal=f"Analyze the market for {self.state.product}",

+            print("result", result.pydantic)
+        else:
+            print("result", result)
+
+        # Return the analysis to update the state
+        return {"analysis": result.pydantic}
+
+    @listen(analyze_market)
+    def present_results(self, analysis) -> None:
+        print("\nMarket Analysis Results")
+        print("=====================")
+
+        if isinstance(analysis, dict):
+            # If we got a dict with 'analysis' key, extract the actual analysis object
+            market_analysis = analysis.get("analysis")
+        else:
+            market_analysis = analysis
+
+        if market_analysis and isinstance(market_analysis, MarketAnalysis):
+            print("\nKey Market Trends:")
+            for trend in market_analysis.key_trends:
+                print(f"- {trend}")
+
+            print(f"\nMarket Size: {market_analysis.market_size}")
+
+            print("\nMajor Competitors:")
+            for competitor in market_analysis.competitors:
+                print(f"- {competitor}")
+        else:
+            print("No structured analysis data available.")
+            print("Raw analysis:", analysis)
+
+
+# Usage example
+async def run_flow():
+    flow = MarketResearchFlow()
+    result = await flow.kickoff_async(inputs={"product": "AI-powered chatbots"})
+    return result
+
+
+# Run the flow
+if __name__ == "__main__":
+    asyncio.run(run_flow())
+```
+
+This example demonstrates several key features of using Agents in flows:
+
+1. **Structured Output**: Using Pydantic models to define the expected output format (`MarketAnalysis`) ensures type safety and structured data throughout the flow.
+
+2. **State Management**: The flow state (`MarketResearchState`) maintains context between steps and stores both inputs and outputs.
+
+3. **Tool Integration**: Agents can use tools (like `WebsiteSearchTool`) to enhance their capabilities.
+
 ## Adding Crews to Flows

+
+### Using External Memory
+
+External Memory is a powerful feature that allows you to integrate external memory systems with your CrewAI applications. This is particularly useful when you want to use specialized memory providers or maintain memory across different applications.
+Since it’s an external memory, we’re not able to add a default value to it - unlike with Long Term and Short Term memory. 
+
+#### Basic Usage with Mem0
+
+The most common way to use External Memory is with Mem0 as the provider:
+
+```python
+import os
+from crewai import Agent, Crew, Process, Task
+from crewai.memory.external.external_memory import ExternalMemory
+
+os.environ["MEM0_API_KEY"] = "YOUR-API-KEY"
+
+agent = Agent(
+    role="You are a helpful assistant",
+    goal="Plan a vacation for the user",
+    backstory="You are a helpful assistant that can plan a vacation for the user",
+    verbose=True,
+)
+task = Task(
+    description="Give things related to the user's vacation",
+    expected_output="A plan for the vacation",
+    agent=agent,
+)
+
+crew = Crew(
+    agents=[agent],
+    tasks=[task],
+    verbose=True,
+    process=Process.sequential,
+    external_memory=ExternalMemory(
+        embedder_config={"provider": "mem0", "config": {"user_id": "U-123"}} # you can provide an entire Mem0 configuration
+    ),
+)
+
+crew.kickoff(
+    inputs={"question": "which destination is better for a beach vacation?"}
+)
+```
+
+#### Using External Memory with Custom Storage
+
+You can also create custom storage implementations for External Memory. Here's an example of how to create a custom storage:
+
+```python
+from crewai import Agent, Crew, Process, Task
+from crewai.memory.external.external_memory import ExternalMemory
+from crewai.memory.storage.interface import Storage
+
+
+class CustomStorage(Storage):
+    def __init__(self):
+        self.memories = []
+
+    def save(self, value, metadata=None, agent=None):
+        self.memories.append({"value": value, "metadata": metadata, "agent": agent})
+
+    def search(self, query, limit=10, score_threshold=0.5):
+        # Implement your search logic here
+        return []
+
+    def reset(self):
+        self.memories = []
+
+
+# Create external memory with custom storage
+external_memory = ExternalMemory(
+    storage=CustomStorage(),
+    embedder_config={"provider": "mem0", "config": {"user_id": "U-123"}},
+)
+
+agent = Agent(
+    role="You are a helpful assistant",
+    goal="Plan a vacation for the user",
+    backstory="You are a helpful assistant that can plan a vacation for the user",
+    verbose=True,
+)
+task = Task(
+    description="Give things related to the user's vacation",
+    expected_output="A plan for the vacation",
+    agent=agent,
+)
+
+crew = Crew(
+    agents=[agent],
+    tasks=[task],
+    verbose=True,
+    process=Process.sequential,
+    external_memory=external_memory,
+)
+
+crew.kickoff(
+    inputs={"question": "which destination is better for a beach vacation?"}
+)

+
+# Arize Phoenix Integration
+
+This guide demonstrates how to integrate **Arize Phoenix** with **CrewAI** using OpenTelemetry via the [OpenInference](https://github.com/openinference/openinference) SDK. By the end of this guide, you will be able to trace your CrewAI agents and easily debug your agents.
+
+> **What is Arize Phoenix?** [Arize Phoenix](https://phoenix.arize.com) is an LLM observability platform that provides tracing and evaluation for AI applications.
+
+[![Watch a Video Demo of Our Integration with Phoenix](https://storage.googleapis.com/arize-assets/fixtures/setup_crewai.png)](https://www.youtube.com/watch?v=Yc5q3l6F7Ww)
+
+## Get Started
+
+We'll walk through a simple example of using CrewAI and integrating it with Arize Phoenix via OpenTelemetry using OpenInference.
+
+You can also access this guide on [Google Colab](https://colab.research.google.com/github/Arize-ai/phoenix/blob/main/tutorials/tracing/crewai_tracing_tutorial.ipynb).
+
+### Step 1: Install Dependencies
+
+```bash
+pip install openinference-instrumentation-crewai crewai crewai-tools arize-phoenix-otel
+```
+
+### Step 2: Set Up Environment Variables
+
+Setup Phoenix Cloud API keys and configure OpenTelemetry to send traces to Phoenix. Phoenix Cloud is a hosted version of Arize Phoenix, but it is not required to use this integration.
+
+You can get your free Serper API key [here](https://serper.dev/).
+
+```python
+import os
+from getpass import getpass
+
+# Get your Phoenix Cloud credentials
+PHOENIX_API_KEY = getpass("🔑 Enter your Phoenix Cloud API Key: ")
+
+# Get API keys for services
+OPENAI_API_KEY = getpass("🔑 Enter your OpenAI API key: ")
+SERPER_API_KEY = getpass("🔑 Enter your Serper API key: ")
+
+# Set environment variables
+os.environ["PHOENIX_CLIENT_HEADERS"] = f"api_key={PHOENIX_API_KEY}"
+os.environ["PHOENIX_COLLECTOR_ENDPOINT"] = "https://app.phoenix.arize.com" # Phoenix Cloud, change this to your own endpoint if you are using a self-hosted instance
+os.environ["OPENAI_API_KEY"] = OPENAI_API_KEY
+os.environ["SERPER_API_KEY"] = SERPER_API_KEY
+```
+
+### Step 3: Initialize OpenTelemetry with Phoenix
+
+Initialize the OpenInference OpenTelemetry instrumentation SDK to start capturing traces and send them to Phoenix. 
+
+```python
+from phoenix.otel import register
+
+tracer_provider = register(
+    project_name="crewai-tracing-demo",
+    auto_instrument=True,
+)
+```
+
+### Step 4: Create a CrewAI Application
+
+We'll create a CrewAI application where two agents collaborate to research and write a blog post about AI advancements.
+
+```python
+from crewai import Agent, Crew, Process, Task
+from crewai_tools import SerperDevTool
+
+search_tool = SerperDevTool()
+
+# Define your agents with roles and goals
+researcher = Agent(
+    role="Senior Research Analyst",
+    goal="Uncover cutting-edge developments in AI and data science",
+    backstory="""You work at a leading tech think tank.
+    Your expertise lies in identifying emerging trends.
+    You have a knack for dissecting complex data and presenting actionable insights.""",
+    verbose=True,
+    allow_delegation=False,
+    # You can pass an optional llm attribute specifying what model you wanna use.
+    # llm=ChatOpenAI(model_name="gpt-3.5", temperature=0.7),
+    tools=[search_tool],
+)
+writer = Agent(
+    role="Tech Content Strategist",
+    goal="Craft compelling content on tech advancements",
+    backstory="""You are a renowned Content Strategist, known for your insightful and engaging articles.
+    You transform complex concepts into compelling narratives.""",
+    verbose=True,
+    allow_delegation=True,
+)
+
+# Create tasks for your agents
+task1 = Task(
+    description="""Conduct a comprehensive analysis of the latest advancements in AI in 2024.
+    Identify key trends, breakthrough technologies, and potential industry impacts.""",
+    expected_output="Full analysis report in bullet points",
+    agent=researcher,
+)
+
+task2 = Task(
+    description="""Using the insights provided, develop an engaging blog
+    post that highlights the most significant AI advancements.
+    Your post should be informative yet accessible, catering to a tech-savvy audience.
+    Make it sound cool, avoid complex words so it doesn't sound like AI.""",
+    expected_output="Full blog post of at least 4 paragraphs",
+    agent=writer,
+)
+
+# Instantiate your crew with a sequential process
+crew = Crew(
+    agents=[researcher, writer], tasks=[task1, task2], verbose=1, process=Process.sequential
+)
+
+# Get your crew to work!
+result = crew.kickoff()
+
+print("######################")
+print(result)
+```
+
+### Step 5: View Traces in Phoenix
+
+After running the agent, you can view the traces generated by your CrewAI application in Phoenix. You should see detailed steps of the agent interactions and LLM calls, which can help you debug and optimize your AI agents.
+
+Log into your Phoenix Cloud account and navigate to the project you specified in the `project_name` parameter. You'll see a timeline view of your trace with all the agent interactions, tool usages, and LLM calls.

+title: Bring your own agent
+description: Learn how to bring your own agents that work within a Crew.
+icon: robots
+---
+
+Interoperability is a core concept in CrewAI. This guide will show you how to bring your own agents that work within a Crew.
+
+
+## Adapter Guide for Bringing your own agents (Langgraph Agents, OpenAI Agents, etc...)
+We require 3 adapters to turn any agent from different frameworks to work within crew.
+
+1. BaseAgentAdapter
+2. BaseToolAdapter
+3. BaseConverter
+
+
+## BaseAgentAdapter
+This abstract class defines the common interface and functionality that all
+agent adapters must implement. It extends BaseAgent to maintain compatibility
+with the CrewAI framework while adding adapter-specific requirements.
+
+Required Methods:
+
+1. `def configure_tools`
+2. `def configure_structured_output`
+
+## Creating your own Adapter
+To integrate an agent from a different framework (e.g., LangGraph, Autogen, OpenAI Assistants) into CrewAI, you need to create a custom adapter by inheriting from `BaseAgentAdapter`. This adapter acts as a compatibility layer, translating between the CrewAI interfaces and the specific requirements of your external agent.
+
+Here's how you implement your custom adapter:
+
+1.  **Inherit from `BaseAgentAdapter`**:
+    ```python
+    from crewai.agents.agent_adapters.base_agent_adapter import BaseAgentAdapter
+    from crewai.tools import BaseTool
+    from typing import List, Optional, Any, Dict
+
+    class MyCustomAgentAdapter(BaseAgentAdapter):
+        # ... implementation details ...
+    ```
+
+2.  **Implement `__init__`**:
+    The constructor should call the parent class constructor `super().__init__(**kwargs)` and perform any initialization specific to your external agent. You can use the optional `agent_config` dictionary passed during CrewAI's `Agent` initialization to configure your adapter and the underlying agent.
+
+    ```python
+    def __init__(self, agent_config: Optional[Dict[str, Any]] = None, **kwargs: Any):
+        super().__init__(agent_config=agent_config, **kwargs)
+        # Initialize your external agent here, possibly using agent_config
+        # Example: self.external_agent = initialize_my_agent(agent_config)
+        print(f"Initializing MyCustomAgentAdapter with config: {agent_config}")
+    ```
+
+3.  **Implement `configure_tools`**:
+    This abstract method is crucial. It receives a list of CrewAI `BaseTool` instances. Your implementation must convert or adapt these tools into the format expected by your external agent framework. This might involve wrapping them, extracting specific attributes, or registering them with the external agent instance.
+
+    ```python
+    def configure_tools(self, tools: Optional[List[BaseTool]] = None) -> None:
+        if tools:
+            adapted_tools = []
+            for tool in tools:
+                # Adapt CrewAI BaseTool to the format your agent expects
+                # Example: adapted_tool = adapt_to_my_framework(tool)
+                # adapted_tools.append(adapted_tool)
+                pass # Replace with your actual adaptation logic
+
+            # Configure the external agent with the adapted tools
+            # Example: self.external_agent.set_tools(adapted_tools)
+            print(f"Configuring tools for MyCustomAgentAdapter: {adapted_tools}") # Placeholder
+        else:
+            # Handle the case where no tools are provided
+            # Example: self.external_agent.set_tools([])
+            print("No tools provided for MyCustomAgentAdapter.")
+    ```
+
+4.  **Implement `configure_structured_output`**:
+    This method is called when the CrewAI `Agent` is configured with structured output requirements (e.g., `output_json` or `output_pydantic`). Your adapter needs to ensure the external agent is set up to comply with these requirements. This might involve setting specific parameters on the external agent or ensuring its underlying model supports the requested format. If the external agent doesn't support structured output in a way compatible with CrewAI's expectations, you might need to handle the conversion or raise an appropriate error.
+
+    ```python
+    def configure_structured_output(self, structured_output: Any) -> None:
+        # Configure your external agent to produce output in the specified format
+        # Example: self.external_agent.set_output_format(structured_output)
+        self.adapted_structured_output = True # Signal that structured output is handled
+        print(f"Configuring structured output for MyCustomAgentAdapter: {structured_output}")
+    ```
+
+By implementing these methods, your `MyCustomAgentAdapter` will allow your custom agent implementation to function correctly within a CrewAI crew, interacting with tasks and tools seamlessly. Remember to replace the example comments and print statements with your actual adaptation logic specific to the external agent framework you are integrating.
+
+## BaseToolAdapter implementation
+The `BaseToolAdapter` class is responsible for converting CrewAI's native `BaseTool` objects into a format that your specific external agent framework can understand and utilize. Different agent frameworks (like LangGraph, OpenAI Assistants, etc.) have their own unique ways of defining and handling tools, and the `BaseToolAdapter` acts as the translator.
+
+Here's how you implement your custom tool adapter:
+
+1.  **Inherit from `BaseToolAdapter`**:
+    ```python
+    from crewai.agents.agent_adapters.base_tool_adapter import BaseToolAdapter
+    from crewai.tools import BaseTool
+    from typing import List, Any
+
+    class MyCustomToolAdapter(BaseToolAdapter):
+        # ... implementation details ...
+    ```
+
+2.  **Implement `configure_tools`**:
+    This is the core abstract method you must implement. It receives a list of CrewAI `BaseTool` instances provided to the agent. Your task is to iterate through this list, adapt each `BaseTool` into the format expected by your external framework, and store the converted tools in the `self.converted_tools` list (which is initialized in the base class constructor).
+
+    ```python
+    def configure_tools(self, tools: List[BaseTool]) -> None:
+        """Configure and convert CrewAI tools for the specific implementation."""
+        self.converted_tools = [] # Reset in case it's called multiple times
+        for tool in tools:
+            # Sanitize the tool name if required by the target framework
+            sanitized_name = self.sanitize_tool_name(tool.name)
+
+            # --- Your Conversion Logic Goes Here ---
+            # Example: Convert BaseTool to a dictionary format for LangGraph
+            # converted_tool = {
+            #     "name": sanitized_name,
+            #     "description": tool.description,
+            #     "parameters": tool.args_schema.schema() if tool.args_schema else {},
+            #     # Add any other framework-specific fields
+            # }
+
+            # Example: Convert BaseTool to an OpenAI function definition
+            # converted_tool = {
+            #     "type": "function",
+            #     "function": {
+            #         "name": sanitized_name,
+            #         "description": tool.description,
+            #         "parameters": tool.args_schema.schema() if tool.args_schema else {"type": "object", "properties": {}},
+            #     }
+            # }
+
+            # --- Replace above examples with your actual adaptation ---
+            converted_tool = self.adapt_tool_to_my_framework(tool, sanitized_name) # Placeholder
+
+            self.converted_tools.append(converted_tool)
+            print(f"Adapted tool '{tool.name}' to '{sanitized_name}' for MyCustomToolAdapter") # Placeholder
+
+        print(f"MyCustomToolAdapter finished configuring tools: {len(self.converted_tools)} adapted.") # Placeholder
+
+    # --- Helper method for adaptation (Example) ---
+    def adapt_tool_to_my_framework(self, tool: BaseTool, sanitized_name: str) -> Any:
+        # Replace this with the actual logic to convert a CrewAI BaseTool
+        # to the format needed by your specific external agent framework.
+        # This will vary greatly depending on the target framework.
+        adapted_representation = {
+            "framework_specific_name": sanitized_name,
+            "framework_specific_description": tool.description,
+            "inputs": tool.args_schema.schema() if tool.args_schema else None,
+            "implementation_reference": tool.run # Or however the framework needs to call it
+        }
+        # Also ensure the tool works both sync and async
+        async def async_tool_wrapper(*args, **kwargs):
+            output = tool.run(*args, **kwargs)
+            if inspect.isawaitable(output):
+                return await output
+            else:
+                return output
+
+        adapted_tool = MyFrameworkTool(
+            name=sanitized_name,
+            description=tool.description,
+            inputs=tool.args_schema.schema() if tool.args_schema else None,
+            implementation_reference=async_tool_wrapper
+        )
+        
+        return adapted_representation
+
+    ```
+
+3.  **Using the Adapter**:
+    Typically, you would instantiate your `MyCustomToolAdapter` within your `MyCustomAgentAdapter`'s `configure_tools` method and use it to process the tools before configuring your external agent.
+
+    ```python
+    # Inside MyCustomAgentAdapter.configure_tools
+    def configure_tools(self, tools: Optional[List[BaseTool]] = None) -> None:
+        if tools:
+            tool_adapter = MyCustomToolAdapter() # Instantiate your tool adapter
+            tool_adapter.configure_tools(tools)  # Convert the tools
+            adapted_tools = tool_adapter.tools() # Get the converted tools
+
+            # Now configure your external agent with the adapted_tools
+            # Example: self.external_agent.set_tools(adapted_tools)
+            print(f"Configuring external agent with adapted tools: {adapted_tools}") # Placeholder
+        else:
+            # Handle no tools case
+            print("No tools provided for MyCustomAgentAdapter.")
+    ```
+
+By creating a `BaseToolAdapter`, you decouple the tool conversion logic from the agent adaptation, making the integration cleaner and more modular. Remember to replace the placeholder examples with the actual conversion logic required by your specific external agent framework.
+
+## BaseConverter
+The `BaseConverterAdapter` plays a crucial role when a CrewAI `Task` requires an agent to return its final output in a specific structured format, such as JSON or a Pydantic model. It bridges the gap between CrewAI's structured output requirements and the capabilities of your external agent.
+
+Its primary responsibilities are:
+1.  **Configuring the Agent for Structured Output:** Based on the `Task`'s requirements (`output_json` or `output_pydantic`), it instructs the associated `BaseAgentAdapter` (and indirectly, the external agent) on what format is expected.
+2.  **Enhancing the System Prompt:** It modifies the agent's system prompt to include clear instructions on *how* to generate the output in the required structure.
+3.  **Post-processing the Result:** It takes the raw output from the agent and attempts to parse, validate, and format it according to the required structure, ultimately returning a string representation (e.g., a JSON string).
+
+Here's how you implement your custom converter adapter:
+
+1.  **Inherit from `BaseConverterAdapter`**:
+    ```python
+    from crewai.agents.agent_adapters.base_converter_adapter import BaseConverterAdapter
+    # Assuming you have your MyCustomAgentAdapter defined
+    # from .my_custom_agent_adapter import MyCustomAgentAdapter
+    from crewai.task import Task
+    from typing import Any
+
+    class MyCustomConverterAdapter(BaseConverterAdapter):
+        # Store the expected output type (e.g., 'json', 'pydantic', 'text')
+        _output_type: str = 'text' 
+        _output_schema: Any = None # Store JSON schema or Pydantic model
+
+        # ... implementation details ...
+    ```
+
+2.  **Implement `__init__`**:
+    The constructor must accept the corresponding `agent_adapter` instance it will work with.
+
+    ```python
+    def __init__(self, agent_adapter: Any): # Use your specific AgentAdapter type hint
+        self.agent_adapter = agent_adapter
+        print(f"Initializing MyCustomConverterAdapter for agent adapter: {type(agent_adapter).__name__}")
+    ```
+
+3.  **Implement `configure_structured_output`**:
+    This method receives the CrewAI `Task` object. You need to check the task's `output_json` and `output_pydantic` attributes to determine the required output structure. Store this information (e.g., in `_output_type` and `_output_schema`) and potentially call configuration methods on your `self.agent_adapter` if the external agent needs specific setup for structured output (which might have been partially handled in the agent adapter's `configure_structured_output` already).
+
+    ```python
+    def configure_structured_output(self, task: Task) -> None:
+        """Configure the expected structured output based on the task."""
+        if task.output_pydantic:
+            self._output_type = 'pydantic'
+            self._output_schema = task.output_pydantic
+            print(f"Converter: Configured for Pydantic output: {self._output_schema.__name__}")
+        elif task.output_json:
+            self._output_type = 'json'
+            self._output_schema = task.output_json
+            print(f"Converter: Configured for JSON output with schema: {self._output_schema}")
+        else:
+            self._output_type = 'text'
+            self._output_schema = None
+            print("Converter: Configured for standard text output.")
+
+        # Optionally, inform the agent adapter if needed
+        # self.agent_adapter.set_output_mode(self._output_type, self._output_schema)
+    ```
+
+4.  **Implement `enhance_system_prompt`**:
+    This method takes the agent's base system prompt string and should append instructions tailored to the currently configured `_output_type` and `_output_schema`. The goal is to guide the LLM powering the agent to produce output in the correct format.
+
+    ```python
+    def enhance_system_prompt(self, base_prompt: str) -> str:
+        """Enhance the system prompt with structured output instructions."""
+        if self._output_type == 'text':
+            return base_prompt # No enhancement needed for plain text
+
+        instructions = "\n\nYour final answer MUST be formatted as "
+        if self._output_type == 'json':
+            schema_str = json.dumps(self._output_schema, indent=2)
+            instructions += f"a JSON object conforming to the following schema:\n```json\n{schema_str}\n```"
+        elif self._output_type == 'pydantic':
+            schema_str = json.dumps(self._output_schema.model_json_schema(), indent=2)
+            instructions += f"a JSON object conforming to the Pydantic model '{self._output_schema.__name__}' with the following schema:\n```json\n{schema_str}\n```"
+
+        instructions += "\nEnsure your entire response is ONLY the valid JSON object, without any introductory text, explanations, or concluding remarks."
+        
+        print(f"Converter: Enhancing prompt for {self._output_type} output.")
+        return base_prompt + instructions
+    ```
+    *Note: The exact prompt engineering might need tuning based on the agent/LLM being used.* 
+
+5.  **Implement `post_process_result`**:
+    This method receives the raw string output from the agent. If structured output was requested (`json` or `pydantic`), you should attempt to parse the string into the expected format. Handle potential parsing errors (e.g., log them, attempt simple fixes, or raise an exception). Crucially, the method must **always return a string**, even if the intermediate format was a dictionary or Pydantic object (e.g., by serializing it back to a JSON string).
+
+    ```python
+    import json
+    from pydantic import ValidationError
+
+    def post_process_result(self, result: str) -> str:
+        """Post-process the agent's result to ensure it matches the expected format."""
+        print(f"Converter: Post-processing result for {self._output_type} output.")
+        if self._output_type == 'json':
+            try:
+                # Attempt to parse and re-serialize to ensure validity and consistent format

+title: Custom LLM Implementation
+description: Learn how to create custom LLM implementations in CrewAI.
+icon: code
+---
+
+## Custom LLM Implementations
+
+CrewAI now supports custom LLM implementations through the `BaseLLM` abstract base class. This allows you to create your own LLM implementations that don't rely on litellm's authentication mechanism.
+
+To create a custom LLM implementation, you need to:
+
+1. Inherit from the `BaseLLM` abstract base class
+2. Implement the required methods:
+   - `call()`: The main method to call the LLM with messages
+   - `supports_function_calling()`: Whether the LLM supports function calling
+   - `supports_stop_words()`: Whether the LLM supports stop words
+   - `get_context_window_size()`: The context window size of the LLM
+
+## Example: Basic Custom LLM
+
+```python
+from crewai import BaseLLM
+from typing import Any, Dict, List, Optional, Union
+
+class CustomLLM(BaseLLM):
+    def __init__(self, api_key: str, endpoint: str):
+        super().__init__()  # Initialize the base class to set default attributes
+        if not api_key or not isinstance(api_key, str):
+            raise ValueError("Invalid API key: must be a non-empty string")
+        if not endpoint or not isinstance(endpoint, str):
+            raise ValueError("Invalid endpoint URL: must be a non-empty string")
+        self.api_key = api_key
+        self.endpoint = endpoint
+        self.stop = []  # You can customize stop words if needed
+        
+    def call(
+        self,
+        messages: Union[str, List[Dict[str, str]]],
+        tools: Optional[List[dict]] = None,
+        callbacks: Optional[List[Any]] = None,
+        available_functions: Optional[Dict[str, Any]] = None,
+    ) -> Union[str, Any]:
+        """Call the LLM with the given messages.
+

+            messages: Input messages for the LLM.
+            tools: Optional list of tool schemas for function calling.
+            callbacks: Optional list of callback functions.
+            available_functions: Optional dict mapping function names to callables.
+            
+        Returns:
+            Either a text response from the LLM or the result of a tool function call.
+            
+        Raises:
+            TimeoutError: If the LLM request times out.
+            RuntimeError: If the LLM request fails for other reasons.

+        """
+        # Implement your own logic to call the LLM

+            }
+            
+            # Convert string message to proper format if needed
+            if isinstance(messages, str):
+                messages = [{"role": "user", "content": messages}]

+```
+
+## Error Handling Best Practices
+
+When implementing custom LLMs, it's important to handle errors properly to ensure robustness and reliability. Here are some best practices:
+
+### 1. Implement Try-Except Blocks for API Calls
+
+Always wrap API calls in try-except blocks to handle different types of errors:
+
+```python
+def call(
+    self,
+    messages: Union[str, List[Dict[str, str]]],
+    tools: Optional[List[dict]] = None,
+    callbacks: Optional[List[Any]] = None,
+    available_functions: Optional[Dict[str, Any]] = None,
+) -> Union[str, Any]:
+    try:
+        # API call implementation
+        response = requests.post(
+            self.endpoint,
+            headers=self.headers,
+            json=self.prepare_payload(messages),
+            timeout=30  # Set a reasonable timeout
+        )
+        response.raise_for_status()  # Raise an exception for HTTP errors
+        return response.json()["choices"][0]["message"]["content"]
+    except requests.Timeout:
+        raise TimeoutError("LLM request timed out")
+    except requests.RequestException as e:
+        raise RuntimeError(f"LLM request failed: {str(e)}")
+    except (KeyError, IndexError, ValueError) as e:
+        raise ValueError(f"Invalid response format: {str(e)}")
+```
+
+### 2. Implement Retry Logic for Transient Failures
+
+For transient failures like network issues or rate limiting, implement retry logic with exponential backoff:
+
+```python
+def call(
+    self,
+    messages: Union[str, List[Dict[str, str]]],
+    tools: Optional[List[dict]] = None,
+    callbacks: Optional[List[Any]] = None,
+    available_functions: Optional[Dict[str, Any]] = None,
+) -> Union[str, Any]:
+    import time
+    
+    max_retries = 3
+    retry_delay = 1  # seconds
+    
+    for attempt in range(max_retries):
+        try:
+            response = requests.post(
+                self.endpoint,
+                headers=self.headers,
+                json=self.prepare_payload(messages),
+                timeout=30
+            )
+            response.raise_for_status()
+            return response.json()["choices"][0]["message"]["content"]
+        except (requests.Timeout, requests.ConnectionError) as e:
+            if attempt < max_retries - 1:
+                time.sleep(retry_delay * (2 ** attempt))  # Exponential backoff
+                continue
+            raise TimeoutError(f"LLM request failed after {max_retries} attempts: {str(e)}")
+        except requests.RequestException as e:
+            raise RuntimeError(f"LLM request failed: {str(e)}")
+```
+
+### 3. Validate Input Parameters
+
+Always validate input parameters to prevent runtime errors:
+
+```python
+def __init__(self, api_key: str, endpoint: str):
+    super().__init__()
+    if not api_key or not isinstance(api_key, str):
+        raise ValueError("Invalid API key: must be a non-empty string")
+    if not endpoint or not isinstance(endpoint, str):
+        raise ValueError("Invalid endpoint URL: must be a non-empty string")
+    self.api_key = api_key
+    self.endpoint = endpoint
+```
+
+### 4. Handle Authentication Errors Gracefully
+
+Provide clear error messages for authentication failures:
+
+```python
+def call(
+    self,
+    messages: Union[str, List[Dict[str, str]]],
+    tools: Optional[List[dict]] = None,
+    callbacks: Optional[List[Any]] = None,
+    available_functions: Optional[Dict[str, Any]] = None,
+) -> Union[str, Any]:
+    try:
+        response = requests.post(self.endpoint, headers=self.headers, json=data)
+        if response.status_code == 401:
+            raise ValueError("Authentication failed: Invalid API key or token")
+        elif response.status_code == 403:
+            raise ValueError("Authorization failed: Insufficient permissions")
+        response.raise_for_status()
+        # Process response
+    except Exception as e:
+        # Handle error
+        raise
+```
+
+## Example: JWT-based Authentication
+
+For services that use JWT-based authentication instead of API keys, you can implement a custom LLM like this:
+
+```python
+from crewai import BaseLLM, Agent, Task
+from typing import Any, Dict, List, Optional, Union
+
+class JWTAuthLLM(BaseLLM):
+    def __init__(self, jwt_token: str, endpoint: str):
+        super().__init__()  # Initialize the base class to set default attributes
+        if not jwt_token or not isinstance(jwt_token, str):
+            raise ValueError("Invalid JWT token: must be a non-empty string")
+        if not endpoint or not isinstance(endpoint, str):
+            raise ValueError("Invalid endpoint URL: must be a non-empty string")
+        self.jwt_token = jwt_token
+        self.endpoint = endpoint
+        self.stop = []  # You can customize stop words if needed
+        
+    def call(
+        self,
+        messages: Union[str, List[Dict[str, str]]],
+        tools: Optional[List[dict]] = None,
+        callbacks: Optional[List[Any]] = None,
+        available_functions: Optional[Dict[str, Any]] = None,
+    ) -> Union[str, Any]:
+        """Call the LLM with JWT authentication.
+        
+        Args:
+            messages: Input messages for the LLM.
+            tools: Optional list of tool schemas for function calling.
+            callbacks: Optional list of callback functions.
+            available_functions: Optional dict mapping function names to callables.
+            
+        Returns:
+            Either a text response from the LLM or the result of a tool function call.
+            
+        Raises:
+            TimeoutError: If the LLM request times out.
+            RuntimeError: If the LLM request fails for other reasons.

+            if isinstance(messages, str):
+                messages = [{"role": "user", "content": messages}]

+
+## Troubleshooting
+
+Here are some common issues you might encounter when implementing custom LLMs and how to resolve them:
+
+### 1. Authentication Failures
+
+**Symptoms**: 401 Unauthorized or 403 Forbidden errors
+
+**Solutions**:
+- Verify that your API key or JWT token is valid and not expired
+- Check that you're using the correct authentication header format
+- Ensure that your token has the necessary permissions
+
+### 2. Timeout Issues
+
+**Symptoms**: Requests taking too long or timing out
+
+**Solutions**:
+- Implement timeout handling as shown in the examples
+- Use retry logic with exponential backoff
+- Consider using a more reliable network connection
+
+### 3. Response Parsing Errors
+
+**Symptoms**: KeyError, IndexError, or ValueError when processing responses
+
+**Solutions**:
+- Validate the response format before accessing nested fields
+- Implement proper error handling for malformed responses
+- Check the API documentation for the expected response format
+
+### 4. Rate Limiting
+
+**Symptoms**: 429 Too Many Requests errors
+
+**Solutions**:
+- Implement rate limiting in your custom LLM
+- Add exponential backoff for retries
+- Consider using a token bucket algorithm for more precise rate control
+
+## Advanced Features
+
+### Logging
+
+Adding logging to your custom LLM can help with debugging and monitoring:
+
+```python
+import logging
+from typing import Any, Dict, List, Optional, Union
+
+class LoggingLLM(BaseLLM):
+    def __init__(self, api_key: str, endpoint: str):
+        super().__init__()
+        self.api_key = api_key
+        self.endpoint = endpoint
+        self.logger = logging.getLogger("crewai.llm.custom")
+        
+    def call(
+        self,
+        messages: Union[str, List[Dict[str, str]]],
+        tools: Optional[List[dict]] = None,
+        callbacks: Optional[List[Any]] = None,
+        available_functions: Optional[Dict[str, Any]] = None,
+    ) -> Union[str, Any]:
+        self.logger.info(f"Calling LLM with {len(messages) if isinstance(messages, list) else 1} messages")
+        try:
+            # API call implementation
+            response = self._make_api_call(messages, tools)
+            self.logger.debug(f"LLM response received: {response[:100]}...")
+            return response
+        except Exception as e:
+            self.logger.error(f"LLM call failed: {str(e)}")
+            raise
+```
+
+### Rate Limiting
+
+Implementing rate limiting can help avoid overwhelming the LLM API:
+
+```python
+import time
+from typing import Any, Dict, List, Optional, Union
+
+class RateLimitedLLM(BaseLLM):
+    def __init__(
+        self, 
+        api_key: str, 
+        endpoint: str, 
+        requests_per_minute: int = 60
+    ):
+        super().__init__()
+        self.api_key = api_key
+        self.endpoint = endpoint
+        self.requests_per_minute = requests_per_minute
+        self.request_times: List[float] = []
+        
+    def call(
+        self,
+        messages: Union[str, List[Dict[str, str]]],
+        tools: Optional[List[dict]] = None,
+        callbacks: Optional[List[Any]] = None,
+        available_functions: Optional[Dict[str, Any]] = None,
+    ) -> Union[str, Any]:
+        self._enforce_rate_limit()
+        # Record this request time
+        self.request_times.append(time.time())
+        # Make the actual API call
+        return self._make_api_call(messages, tools)
+        
+    def _enforce_rate_limit(self) -> None:
+        """Enforce the rate limit by waiting if necessary."""
+        now = time.time()
+        # Remove request times older than 1 minute
+        self.request_times = [t for t in self.request_times if now - t < 60]
+        
+        if len(self.request_times) >= self.requests_per_minute:
+            # Calculate how long to wait
+            oldest_request = min(self.request_times)
+            wait_time = 60 - (now - oldest_request)
+            if wait_time > 0:
+                time.sleep(wait_time)
+```
+
+### Metrics Collection
+
+Collecting metrics can help you monitor your LLM usage:
+
+```python
+import time
+from typing import Any, Dict, List, Optional, Union
+
+class MetricsCollectingLLM(BaseLLM):
+    def __init__(self, api_key: str, endpoint: str):
+        super().__init__()
+        self.api_key = api_key
+        self.endpoint = endpoint
+        self.metrics: Dict[str, Any] = {
+            "total_calls": 0,
+            "total_tokens": 0,
+            "errors": 0,
+            "latency": []
+        }
+        
+    def call(
+        self,
+        messages: Union[str, List[Dict[str, str]]],
+        tools: Optional[List[dict]] = None,
+        callbacks: Optional[List[Any]] = None,
+        available_functions: Optional[Dict[str, Any]] = None,
+    ) -> Union[str, Any]:
+        start_time = time.time()
+        self.metrics["total_calls"] += 1
+        
+        try:
+            response = self._make_api_call(messages, tools)
+            # Estimate tokens (simplified)
+            if isinstance(messages, str):
+                token_estimate = len(messages) // 4
+            else:
+                token_estimate = sum(len(m.get("content", "")) // 4 for m in messages)
+            self.metrics["total_tokens"] += token_estimate
+            return response
+        except Exception as e:
+            self.metrics["errors"] += 1
+            raise
+        finally:
+            latency = time.time() - start_time
+            self.metrics["latency"].append(latency)
+            
+    def get_metrics(self) -> Dict[str, Any]:
+        """Return the collected metrics."""
+        avg_latency = sum(self.metrics["latency"]) / len(self.metrics["latency"]) if self.metrics["latency"] else 0
+        return {
+            **self.metrics,
+            "avg_latency": avg_latency
+        }
+```
+
+## Advanced Usage: Function Calling
+
+If your LLM supports function calling, you can implement the function calling logic in your custom LLM:
+
+```python
+import json
+from typing import Any, Dict, List, Optional, Union
+
+def call(
+    self,
+    messages: Union[str, List[Dict[str, str]]],
+    tools: Optional[List[dict]] = None,
+    callbacks: Optional[List[Any]] = None,
+    available_functions: Optional[Dict[str, Any]] = None,
+) -> Union[str, Any]:
+    import requests
+    
+    try:
+        headers = {
+            "Authorization": f"Bearer {self.jwt_token}",
+            "Content-Type": "application/json"
+        }
+        
+        # Convert string message to proper format if needed
+        if isinstance(messages, str):
+            messages = [{"role": "user", "content": messages}]
+        
+        data = {
+            "messages": messages,
+            "tools": tools
+        }
+        
+        response = requests.post(
+            self.endpoint,
+            headers=headers,
+            json=data,
+            timeout=30
+        )
+        response.raise_for_status()
+        response_data = response.json()
+        
+        # Check if the LLM wants to call a function
+        if response_data["choices"][0]["message"].get("tool_calls"):
+            tool_calls = response_data["choices"][0]["message"]["tool_calls"]
+            
+            # Process each tool call
+            for tool_call in tool_calls:
+                function_name = tool_call["function"]["name"]
+                function_args = json.loads(tool_call["function"]["arguments"])
+                
+                if available_functions and function_name in available_functions:
+                    function_to_call = available_functions[function_name]
+                    function_response = function_to_call(**function_args)
+                    
+                    # Add the function response to the messages
+                    messages.append({
+                        "role": "tool",
+                        "tool_call_id": tool_call["id"],
+                        "name": function_name,
+                        "content": str(function_response)
+                    })
+            
+            # Call the LLM again with the updated messages
+            return self.call(messages, tools, callbacks, available_functions)
+        
+        # Return the text response if no function call
+        return response_data["choices"][0]["message"]["content"]
+    except requests.Timeout:
+        raise TimeoutError("LLM request timed out")
+    except requests.RequestException as e:
+        raise RuntimeError(f"LLM request failed: {str(e)}")
+    except (KeyError, IndexError, ValueError) as e:
+        raise ValueError(f"Invalid response format: {str(e)}")
+```
+
+## Using Your Custom LLM with CrewAI
+
+Once you've implemented your custom LLM, you can use it with CrewAI agents and crews:
+
+```python
+from crewai import Agent, Task, Crew
+from typing import Dict, Any
+
+# Create your custom LLM instance
+jwt_llm = JWTAuthLLM(
+    jwt_token="your.jwt.token", 
+    endpoint="https://your-llm-endpoint.com/v1/chat/completions"
+)
+
+# Use it with an agent
+agent = Agent(
+    role="Research Assistant",
+    goal="Find information on a topic",
+    backstory="You are a research assistant tasked with finding information.",
+    llm=jwt_llm,
+)
+
+# Create a task for the agent
+task = Task(
+    description="Research the benefits of exercise",
+    agent=agent,
+    expected_output="A summary of the benefits of exercise",
+)
+
+# Execute the task
+result = agent.execute_task(task)
+print(result)
+
+# Or use it with a crew
+crew = Crew(
+    agents=[agent],
+    tasks=[task],
+    manager_llm=jwt_llm,  # Use your custom LLM for the manager
+)
+
+# Run the crew
+result = crew.kickoff()
+print(result)
+```
+
+## Implementing Your Own Authentication Mechanism
+
+The `BaseLLM` class allows you to implement any authentication mechanism you need, not just JWT or API keys. You can use:
+
+- OAuth tokens
+- Client certificates
+- Custom headers
+- Session-based authentication
+- Any other authentication method required by your LLM provider
+
+Simply implement the appropriate authentication logic in your custom LLM class.

+
+To run the Opik platform locally, see our [installation guide](https://www.comet.com/docs/opik/self-host/overview/) for more information.
+
+For this guide we will use CrewAI’s quickstart example.
+
+<Steps>
+    <Step title="Install required packages">
+      ```shell
+      pip install crewai crewai-tools opik --upgrade
+      ```
+    </Step>
+    <Step title="Configure Opik">
+      ```python
+      import opik
+      opik.configure(use_local=False)
+      ```
+    </Step>
+    <Step title="Prepare environment">
+      First, we set up our API keys for our LLM-provider as environment variables:
+  
+      ```python
+      import os
+      import getpass
+
+      if "OPENAI_API_KEY" not in os.environ:
+      os.environ["OPENAI_API_KEY"] = getpass.getpass("Enter your OpenAI API key: ")
+      ```
+    </Step>
+    <Step title="Using CrewAI">
+      The first step is to create our project. We will use an example from CrewAI’s documentation:
+
+      ```python
+      from crewai import Agent, Crew, Task, Process
+
+
+      class YourCrewName:
+          def agent_one(self) -> Agent:
+              return Agent(
+                  role="Data Analyst",
+                  goal="Analyze data trends in the market",
+                  backstory="An experienced data analyst with a background in economics",
+                  verbose=True,
+              )

+          def agent_two(self) -> Agent:
+              return Agent(
+                  role="Market Researcher",
+                  goal="Gather information on market dynamics",
+                  backstory="A diligent researcher with a keen eye for detail",
+                  verbose=True,
+              )
+
+          def task_one(self) -> Task:
+              return Task(
+                  name="Collect Data Task",
+                  description="Collect recent market data and identify trends.",
+                  expected_output="A report summarizing key trends in the market.",
+                  agent=self.agent_one(),
+              )
+
+          def task_two(self) -> Task:
+              return Task(
+                  name="Market Research Task",
+                  description="Research factors affecting market dynamics.",
+                  expected_output="An analysis of factors influencing the market.",
+                  agent=self.agent_two(),
+              )
+
+          def crew(self) -> Crew:
+              return Crew(
+                  agents=[self.agent_one(), self.agent_two()],
+                  tasks=[self.task_one(), self.task_two()],
+                  process=Process.sequential,
+                  verbose=True,
+              )
+
+      ```
+
+      Now we can import Opik’s tracker and run our crew:
+  
+      ```python
+      from opik.integrations.crewai import track_crewai
+
+      track_crewai(project_name="crewai-integration-demo")
+
+      my_crew = YourCrewName().crew()
+      result = my_crew.kickoff()
+
+      print(result)
+      ```
+      After running your CrewAI application, visit the Opik app to view:
+      - LLM traces, spans, and their metadata
+      - Agent interactions and task execution flow
+      - Performance metrics like latency and token usage
+      - Evaluation metrics (built-in or custom)
+    </Step>
+</Steps>

+## Features
+
+- Weave automatically captures all CrewAI operations: agent interactions and task executions; LLM calls with metadata and token usage; tool usage and results.
+- The integration supports all CrewAI execution methods: `kickoff()`, `kickoff_for_each()`, `kickoff_async()`, and `kickoff_for_each_async()`.
+- Automatic tracing of all [crewAI-tools](https://github.com/crewAIInc/crewAI-tools).
+- Flow feature support with decorator patching (`@start`, `@listen`, `@router`, `@or_`, `@and_`).
+- Track custom guardrails passed to CrewAI `Task` with `@weave.op()`.
+
+For detailed information on what's supported, visit the [Weave CrewAI documentation](https://weave-docs.wandb.ai/guides/integrations/crewai/#getting-started-with-flow).
