Usage

import os
from mem0 import Memory

os.environ["OPENAI_API_KEY"] = "your-api-key"

config = {
    "llm": {
        "provider": "openai",
        "config": {
            "model": "gpt-4o",
            "temperature": 0.2,
            "max_tokens": 2000,
        }
    }
}

# Use Openrouter by passing it's api key
# os.environ["OPENROUTER_API_KEY"] = "your-api-key"
# config = {
#    "llm": {
#        "provider": "openai",

m = Memory.from_config(config)
messages = [
    {"role": "user", "content": "I'm planning to watch a movie tonight. Any recommendations?"},
    {"role": "assistant", "content": "How about a thriller movies? They can be quite engaging."},

m.add(messages, user_id="alice", metadata={"category": "movies"})
We also support the new OpenAI structured-outputs model.
