# Mem0 Integration Patterns

Working code examples for integrating Mem0 Platform with popular AI frameworks.
All examples use `MemoryClient` (Platform API key).

Code examples are sourced from official Mem0 integration docs at docs.mem0.ai, simplified for quick reference.

---

## Common Pattern

Every integration follows the same 3-step loop:

1. **Retrieve** -- search relevant memories before generating a response
2. **Generate** -- include memories as context in the LLM prompt
3. **Store** -- save the interaction back to Mem0 for future use

---

## LangChain

Source: [docs.mem0.ai/integrations/langchain](https://docs.mem0.ai/integrations/langchain)

```python
from langchain_openai import ChatOpenAI
from langchain_core.messages import SystemMessage, HumanMessage
from langchain_core.prompts import ChatPromptTemplate, MessagesPlaceholder
from mem0 import MemoryClient

llm = ChatOpenAI(model="gpt-5-mini")
mem0 = MemoryClient()

prompt = ChatPromptTemplate.from_messages([
    SystemMessage(content="You are a helpful travel agent AI. Use the provided context to personalize your responses."),
    MessagesPlaceholder(variable_name="context"),
    HumanMessage(content="{input}")
])

def retrieve_context(query: str, user_id: str):
    """Retrieve relevant memories from Mem0"""
    memories = mem0.search(query, user_id=user_id)
    memory_list = memories['results']
    serialized = ' '.join([m["memory"] for m in memory_list])
    return [
        {"role": "system", "content": f"Relevant information: {serialized}"},
        {"role": "user", "content": query}
    ]

def chat_turn(user_input: str, user_id: str) -> str:
    # 1. Retrieve
    context = retrieve_context(user_input, user_id)
    # 2. Generate
    chain = prompt | llm
    response = chain.invoke({"context": context, "input": user_input})
    # 3. Store
    mem0.add(
        [{"role": "user", "content": user_input}, {"role": "assistant", "content": response.content}],
        user_id=user_id
    )
    return response.content
```

---

## CrewAI

Source: [docs.mem0.ai/integrations/crewai](https://docs.mem0.ai/integrations/crewai)

CrewAI has native Mem0 integration via `memory_config`:

```python
from crewai import Agent, Task, Crew, Process
from mem0 import MemoryClient

client = MemoryClient()

# Store user preferences first
messages = [
    {"role": "user", "content": "I am more of a beach person than a mountain person."},
    {"role": "assistant", "content": "Noted! I'll recommend beach destinations."},
    {"role": "user", "content": "I like Airbnb more than hotels."},
]
client.add(messages, user_id="crew_user_1")

# Create agent
travel_agent = Agent(
    role="Personalized Travel Planner",
    goal="Plan personalized travel itineraries",
    backstory="You are a seasoned travel planner.",
    memory=True,
)

# Create task
task = Task(
    description="Find places to live, eat, and visit in San Francisco.",
    expected_output="A detailed list of places to live, eat, and visit.",
    agent=travel_agent,
)

# Setup crew with Mem0 memory
crew = Crew(
    agents=[travel_agent],
    tasks=[task],
    process=Process.sequential,
    memory=True,
    memory_config={
        "provider": "mem0",
        "config": {"user_id": "crew_user_1"},
    }
)

result = crew.kickoff()
```

Source: [docs.mem0.ai/integrations/openai-agents-sdk](https://docs.mem0.ai/integrations/openai-agents-sdk)

```python
from agents import Agent, Runner, function_tool
from mem0 import MemoryClient

mem0 = MemoryClient()

@function_tool
def search_memory(query: str, user_id: str) -> str:
    """Search through past conversations and memories"""
    memories = mem0.search(query, user_id=user_id, top_k=3)
    if memories and memories.get('results'):
        return "\n".join([f"- {mem['memory']}" for mem in memories['results']])
    return "No relevant memories found."

@function_tool
def save_memory(content: str, user_id: str) -> str:
    """Save important information to memory"""
    mem0.add([{"role": "user", "content": content}], user_id=user_id)
    return "Information saved to memory."

agent = Agent(
    name="Personal Assistant",
    instructions="""You are a helpful personal assistant with memory capabilities.
    Use search_memory to recall past conversations.
    Use save_memory to store important information.""",
    tools=[search_memory, save_memory],
    model="gpt-5-mini"
)

result = Runner.run_sync(agent, "I love Italian food and I'm planning a trip to Rome next month")
print(result.final_output)
```

## LangGraph

Source: [docs.mem0.ai/integrations/langgraph](https://docs.mem0.ai/integrations/langgraph)

State-based agent workflows with memory persistence. Best for complex conversation flows with branching logic.

```python
from typing import Annotated, TypedDict, List
from langgraph.graph import StateGraph, START
from langgraph.graph.message import add_messages
from langchain_openai import ChatOpenAI
from mem0 import MemoryClient
from langchain_core.messages import SystemMessage, HumanMessage, AIMessage

llm = ChatOpenAI(model="gpt-5-mini")
mem0 = MemoryClient()

class State(TypedDict):
    messages: Annotated[List[HumanMessage | AIMessage], add_messages]
    mem0_user_id: str

def chatbot(state: State):
    messages = state["messages"]
    user_id = state["mem0_user_id"]

    # Retrieve relevant memories
    memories = mem0.search(messages[-1].content, user_id=user_id)
    context = "Relevant context:\n"
    for memory in memories["results"]:
        context += f"- {memory['memory']}\n"

    system_message = SystemMessage(content=f"""You are a helpful support assistant.
{context}""")

    response = llm.invoke([system_message] + messages)

    # Store the interaction
    mem0.add(
        [{"role": "user", "content": messages[-1].content},
         {"role": "assistant", "content": response.content}],
        user_id=user_id
    )
    return {"messages": [response]}

graph = StateGraph(State)
graph.add_node("chatbot", chatbot)
graph.add_edge(START, "chatbot")
app = graph.compile()

# Usage
result = app.invoke({
    "messages": [HumanMessage(content="I need help with my order")],
    "mem0_user_id": "customer_123"
})
```

## LlamaIndex

Source: [docs.mem0.ai/integrations/llama-index](https://docs.mem0.ai/integrations/llama-index)

Install: `pip install llama-index-core llama-index-memory-mem0`

LlamaIndex has native Mem0 support via `Mem0Memory`. Works with ReAct and FunctionCalling agents.

```python
from llama_index.memory.mem0 import Mem0Memory

context = {"user_id": "alice", "agent_id": "llama_agent_1"}
memory = Mem0Memory.from_client(
    context=context,
    search_msg_limit=4,  # messages from chat history used for retrieval (default: 5)
)

# Use with LlamaIndex agent
from llama_index.core.agent import FunctionCallingAgent
from llama_index.llms.openai import OpenAI

llm = OpenAI(model="gpt-5-mini")
agent = FunctionCallingAgent.from_tools(
    tools=[],
    llm=llm,
    memory=memory,
    verbose=True,
)

response = agent.chat("I prefer vegetarian restaurants")
# Memory automatically stores and retrieves context
response = agent.chat("What kind of food do I like?")
# Agent retrieves the vegetarian preference from Mem0
```

---

## AutoGen

Source: [docs.mem0.ai/integrations/autogen](https://docs.mem0.ai/integrations/autogen)

Install: `pip install autogen mem0ai`

Multi-agent conversational systems with memory persistence.

```python
from autogen import ConversableAgent
from mem0 import MemoryClient

memory_client = MemoryClient()
USER_ID = "alice"

agent = ConversableAgent(
    "chatbot",
    llm_config={"config_list": [{"model": "gpt-5-mini", "api_key": os.environ["OPENAI_API_KEY"]}]},
    code_execution_config=False,
    human_input_mode="NEVER",
)

def get_context_aware_response(question: str) -> str:
    # Retrieve memories for context
    relevant_memories = memory_client.search(question, user_id=USER_ID)
    context = "\n".join([m["memory"] for m in relevant_memories.get("results", [])])

    prompt = f"""Answer considering previous interactions:
    Previous context: {context}
    Question: {question}"""

    reply = agent.generate_reply(messages=[{"content": prompt, "role": "user"}])

    # Store the new interaction
    memory_client.add(
        [{"role": "user", "content": question}, {"role": "assistant", "content": reply}],
        user_id=USER_ID
    )
    return reply
```
