Last version as MemGPT

[AtakanTekparmak]

I've recently had to chance to read the MemGPT Paper and wanted to implement and test it with new SLMs like the Qwen2.5 series locally. Now however I see the repo for the paper implementation of MemGPT turned into Letta, which has a lot of features on top of the MemGPT implementation. My questions following this are:

1. When did the transition from MemGPT to Letta occur? This could be helpful in finding the last commit with the MemGPT implementation.
2. Where can I find the last stable version of MemGPT before it became Letta? A commit, a branch, anything could be helpful, since I need just the implementation of the paper and nothing else.

Thanks in advance 🙏

Hi @AtakanTekparmak - the default agent created in Letta is a MemGPT agent. The primary difference with Letta is that we allow you to add additional tools beyond the base MemGPT memory management tools, extensible memory, and running as a service. You can see our documentation on running locally with LMStudio and Ollama.

I think if you go back to version ~0.2, you will be able to see the original CLI-only version of MemGPT. But the underlying implementation is the same, the primary difference is the extensibility and service model.
