Overview

What is MemGPT?

MemGPT is a framework that teaches large language models how to manage their own memory, enabling them to handle unbounded context. This makes it ideal for applications requiring long-term memory and complex reasoning.

Key differentiator

MemGPT stands out by focusing on teaching LLMs to manage their own memory, a unique approach enabling unbounded context and complex reasoning that is not commonly addressed in other frameworks.
