​
Message History Limit

Limit context size to reduce token usage: 
import asyncio
from upsonic import Agent, Chat


async def main():
    agent = Agent("openai/gpt-4o")

    chat = Chat(
        session_id="session1",
        user_id="user1",
        agent=agent,
        num_last_messages=20
    )

    for i in range(30):
        await chat.invoke(f"Message {i}")

    print(f"Total stored: {len(chat.all_messages)}")


if __name__ == "__main__":
    asyncio.run(main())

​
Summarization

Enable automatic conversation summarization: 
import asyncio
from upsonic import Agent, Chat


async def main():
    agent = Agent("openai/gpt-4o")

    chat = Chat(
        session_id="session1",
        user_id="user1",
        agent=agent,
        full_session_memory=True,
        summary_memory=True
    )

    await chat.invoke("Tell me about machine learning")
    await chat.invoke("What about deep learning?")
    await chat.invoke("Summarize what we discussed")


if __name__ == "__main__":
    asyncio.run(main())

​
Tool Call Results

Include tool execution results in memory: 
import asyncio
from upsonic import Agent, Chat


def get_weather(city: str) -> str:
    """Get current weather for a city."""
    return f"Sunny, 22°C in {city}"


async def main():
    agent = Agent("openai/gpt-4o", tools=[get_weather])

    chat = Chat(
        session_id="session1",
        user_id="user1",
        agent=agent,
        feed_tool_call_results=True
    )

    response = await chat.invoke("What is the weather in Paris?")
    print(response)


if __name__ == "__main__":
    asyncio.run(main())

​
Memory Mode

Control how user profiles are updated: 
import asyncio
from upsonic import Agent, Chat


async def main():
    agent = Agent("openai/gpt-4o")

    chat = Chat(
        session_id="session1",
        user_id="user1",
        agent=agent,
        user_analysis_memory=True,
        user_memory_mode="update"
    )

    await chat.invoke("I like Python")
    await chat.invoke("I also like JavaScript")


if __name__ == "__main__":
    asyncio.run(main())
