MemGPT: Extending LLM Context Limits

Even with massive context windows (like 128k or 1M tokens), LLMs eventually run out of space. MemGPT brings the concept of "memory hierarchy" from operating systems to AI, allowing agents to manage their own long-term memory store.

Virtual Memory for LLMs

MemGPT teaches the LLM how to "swap" data between a fast but small "main memory" (the prompt context) and a massive "disk" (a vector database). This allows an agent to hold a conversation spanning thousands of hours, retaining long-term memories that it can recall exactly when needed.

Autonomous Recall

By automating the storage and retrieval process, MemGPT allows your agents to manage their own personal knowledge base, making them vastly more capable at handling tasks that require persistent context over time.
