In-Memory Storage for Agents

InMemoryDb stores an Agent's sessions and run history in the current Python process. Data is lost when the process exits.

Usage

Start in a virtual environment and set the model key before running the example.

Set OpenAI Key

Set your OPENAI_API_KEY as an environment variable. You can get one from OpenAI.

export OPENAI_API_KEY=sk-***

Install dependencies:

uv pip install agno openai

from agno.agent import Agent
from agno.db.in_memory import InMemoryDb

db = InMemoryDb()

agent = Agent(db=db, add_history_to_context=True)

agent.print_response("Give me an easy dinner recipe")
agent.print_response("Which ingredients did you just recommend?")

Run the Example

Save the code as in_memory_for_agent.py, complete the prerequisites above, then run:

python in_memory_for_agent.py
