Overview

InMemoryStorage provides a fast, ephemeral storage backend. Ideal for development, testing, and scenarios where persistence isn’t required.
Data is lost when the process terminates. Use a persistent storage for production.

​
Basic Usage

from upsonic import Agent, Task
from upsonic.storage.memory import Memory
from upsonic.storage.in_memory import InMemoryStorage

storage = InMemoryStorage()

memory = Memory(
    storage=storage,
    session_id="session_001",
    user_id="user_123",
    full_session_memory=True,
    summary_memory=True,
    user_analysis_memory=True,
    model="anthropic/claude-sonnet-4-5"
)

agent = Agent("anthropic/claude-sonnet-4-5", memory=memory)

result1 = agent.do(Task("My name is Alice"))
result2 = agent.do(Task("What's my name?"))
print(result2)  # "Your name is Alice"
