Installing Letta Desktop
Letta Desktop bundles the Letta server and ADE into a single local application. When running, it provides full access to the Letta API at https://localhost:8283.

Note: Since version 0.8.9, Letta uses sqlite as the embedded DB. If you wish to continue using Postgres, migrate your data and use the external Postgres support.
Adding LLM backends
The Letta server can be connected to various LLM API backends. You can add additional LLM API backends by opening the integrations panel (clicking the icon). When you configure a new integration (by setting the environment variable in the dialog), the Letta server will be restarted to load the new LLM API backend.
You can also edit the environment variable file directly, located at ~/.letta/env.
For this quickstart demo, we’ll add an OpenAI API key (once we enter our key and click confirm, the Letta server will automatically restart):
