šŸ“¢ Announcing our research paper: Mem0 achieves 26% higher accuracy than OpenAI Memory, 91% lower latency, and 90% token savings! Read the paper to learn how we're revolutionizing AI agent memory.

To use the Gemini model, set the GEMINI_API_KEY environment variable. You can obtain the Gemini API key from Google AI Studio.

Note: As of the latest release, Mem0 uses the new google.genai SDK instead of the deprecated google.generativeai. All message formatting and model interaction now use the updated types module from google.genai.

Note: Some Gemini models are being deprecated and will retire soon. It is recommended to migrate to the latest stable models like "gemini-2.0-flash-001" or "gemini-2.0-flash-lite-001" to ensure ongoing support and improvements.

Usage

from mem0 import Memory

os.environ["OPENAI_API_KEY"] = "your-openai-api-key"  # Used for embedding model
os.environ["GEMINI_API_KEY"] = "your-gemini-api-key"
