MemGPT Has a Free API: Build AI Agents with Unlimited Memory

MemGPT is an open-source framework that gives large language models (LLMs) unlimited memory through a virtual context management system, allowing for persistent memory, infinite context, self-organizing memory, and tiered storage.

Details

MemGPT (now called Letta) is an open-source framework that addresses the limitations of current LLMs, which are typically constrained by a fixed context window. MemGPT introduces a virtual context management system that allows AI agents to manage their own memory, storing, retrieving, and organizing information like a human would. This enables features like persistent memory across conversations, the ability to process documents larger than any context window, self-organizing memory that decides what to remember and forget, and tiered storage with hot/warm/cold memory. The MemGPT API allows developers to create AI agents with customizable memory and persona, and load documents into an archival memory that can be searched semantically. The memory architecture includes a core memory for the current context, a searchable recall memory for past conversations, and an unlimited archival memory for documents and knowledge.
