A Coding Information to Unlock mem0 Reminiscence for Anthropic Claude Bot: Enabling Context-Wealthy Conversations

On this tutorial, we stroll you thru organising a completely purposeful bot in Google Colab that leverages Anthropic’s Claude mannequin alongside mem0 for seamless reminiscence recall. Combining LangGraph’s intuitive state-machine orchestration with mem0’s highly effective vector-based reminiscence retailer will empower our assistant to recollect previous conversations, retrieve related particulars on demand, and keep pure continuity throughout periods. Whether or not you’re constructing assist bots, digital assistants, or interactive demos, this information will equip you with a strong basis for memory-driven AI experiences.

!pip set up -qU langgraph mem0ai langchain langchain-anthropic anthropic

First, we set up and improve LangGraph, the Mem0 AI consumer, LangChain with its Anthropic connector, and the core Anthropic SDK, guaranteeing we’ve got all the most recent libraries required for constructing a memory-driven Claude chatbot in Google Colab. Operating it upfront will keep away from dependency points and streamline the setup course of.

import os
from typing import Annotated, TypedDict, Listing


from langgraph.graph import StateGraph, START
from langgraph.graph.message import add_messages
from langchain_core.messages import SystemMessage, HumanMessage, AIMessage
from langchain_anthropic import ChatAnthropic
from mem0 import MemoryClient

We convey collectively the core constructing blocks for our Colab chatbot: it hundreds the operating-system interface for API keys, Python’s typed dictionaries and annotation utilities for outlining conversational state, LangGraph’s graph and message decorators to orchestrate chat move, LangChain’s message courses for establishing prompts, the ChatAnthropic wrapper to name Claude, and Mem0’s consumer for persistent reminiscence storage.

os.environ["ANTHROPIC_API_KEY"] = "Use Your Personal API Key"
MEM0_API_KEY = "Use Your Personal API Key"

We securely inject our Anthropic and Mem0 credentials into the atmosphere and an area variable, guaranteeing that the ChatAnthropic consumer and Mem0 reminiscence retailer can authenticate correctly with out hard-coding delicate keys all through our pocket book. Centralizing our API keys right here, we keep a clear separation between code and secrets and techniques whereas enabling seamless entry to the Claude mannequin and protracted reminiscence layer.

llm = ChatAnthropic(
    mannequin="claude-3-5-haiku-latest",
    temperature=0.0,
    max_tokens=1024,
    anthropic_api_key=os.environ["ANTHROPIC_API_KEY"]
)
mem0 = MemoryClient(api_key=MEM0_API_KEY)

We initialize our conversational AI core: first, it creates a ChatAnthropic occasion configured to speak with Claude 3.5 Sonnet at zero temperature for deterministic replies and as much as 1024 tokens per response, utilizing our saved Anthropic key for authentication. Then it spins up a Mem0 MemoryClient with our Mem0 API key, giving our bot a persistent vector-based reminiscence retailer to save lots of and retrieve previous interactions seamlessly.

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


graph = StateGraph(State)


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


    reminiscences = mem0.search(messages[-1].content material, user_id=user_id)


    context = "n".be part of(f"- {m['memory']}" for m in reminiscences)
    system_message = SystemMessage(content material=(
        "You're a useful buyer assist assistant. "
        "Use the context beneath to personalize your solutions:n" + context
    ))


    full_msgs = [system_message] + messages
    ai_resp: AIMessage = llm.invoke(full_msgs)


    mem0.add(
        f"Person: {messages[-1].content material}nAssistant: {ai_resp.content material}",
        user_id=user_id
    )


    return {"messages": [ai_resp]}

We outline the conversational state schema and wire it right into a LangGraph state machine: the State TypedDict tracks the message historical past and a Mem0 person ID, and graph = StateGraph(State) units up the move controller. Throughout the chatbot, the newest person message is used to question Mem0 for related reminiscences, a context-enhanced system immediate is constructed, Claude generates a reply, and that new change is saved again into Mem0 earlier than returning the assistant’s response.

graph.add_node("chatbot", chatbot)
graph.add_edge(START, "chatbot")
graph.add_edge("chatbot", "chatbot")
compiled_graph = graph.compile()

We plug our chatbot perform into LangGraph’s execution move by registering it as a node named “chatbot,” then connecting the built-in START marker to that node. Therefore, the dialog begins there, and at last creates a self-loop edge so every new person message re-enters the identical logic. Calling graph.compile() then transforms this node-and-edge setup into an optimized, runnable graph object that can handle every flip of our chat session routinely.

def run_conversation(user_input: str, mem0_user_id: str):
    config = {"configurable": {"thread_id": mem0_user_id}}
    state = {"messages": [HumanMessage(content=user_input)], "mem0_user_id": mem0_user_id}
    for occasion in compiled_graph.stream(state, config):
        for node_output in occasion.values():
            if node_output.get("messages"):
                print("Assistant:", node_output["messages"][-1].content material)
                return


if __name__ == "__main__":
    print("Welcome! (sort 'exit' to give up)")
    mem0_user_id = "customer_123"  
    whereas True:
        user_in = enter("You: ")
        if user_in.decrease() in ["exit", "quit", "bye"]:
            print("Assistant: Goodbye!")
            break
        run_conversation(user_in, mem0_user_id)

We tie every little thing collectively by defining run_conversation, which packages our person enter into the LangGraph state, streams it via the compiled graph to invoke the chatbot node, and prints out Claude’s reply. The __main__ guard then launches a easy REPL loop, prompting us to sort messages, routing them via our memory-enabled graph, and gracefully exiting once we enter “exit”.

In conclusion, we’ve assembled a conversational AI pipeline that mixes Anthropic’s cutting-edge Claude mannequin with mem0’s persistent reminiscence capabilities, all orchestrated by way of LangGraph in Google Colab. This structure permits our bot to recall user-specific particulars, adapt responses over time, and ship customized assist. From right here, take into account experimenting with richer memory-retrieval methods, fine-tuning Claude’s prompts, or integrating further instruments into your graph.
