+> [!NOTE]  
+> **Looking for MemGPT?**
+> 
+> The MemGPT package and Docker image have been renamed to `letta` to clarify the distinction between **MemGPT agents** and the API server / runtime that runs LLM agents as *services*.
+> 
+> You use the **Letta framework** to create **MemGPT agents**. Read more about the relationship between MemGPT and Letta [here](https://www.letta.com/blog/memgpt-and-letta).

 See [documentation](https://docs.letta.com/introduction) for setup and usage.
