Ollama

Configure Ollama as an embedding provider in Mem0 to generate embeddings locally using open-source models.

You can use embedding models from Ollama to run Mem0 locally.

Usage

Python

import os
from mem0 import Memory

os.environ["OPENAI_API_KEY"] = "your_api_key" # For LLM

config = {
    "embedder": {
        "provider": "ollama",
        "config": {
            "model": "mxbai-embed-large"
        }
    }
}

m = Memory.from_config(config)
messages = [
    {"role": "user", "content": "I'm planning to watch a movie tonight. Any recommendations?"},
    {"role": "assistant", "content": "How about thriller movies? They can be quite engaging."},
    {"role": "user", "content": "I'm not a big fan of thriller movies but I love sci-fi movies."},
    {"role": "assistant", "content": "Got it! I'll avoid thriller recommendations and suggest sci-fi movies in the future."}
]
m.add(messages, user_id="john")

import { Memory } from 'mem0ai/oss';

const config = {
  embedder: {
    provider: 'ollama',
    config: {
      model: 'nomic-embed-text:latest', // or any other Ollama embedding model
