When it is fully up, open the web UI and log in with the default account root and password 1234.

Running your own instance still means a Docker deployment.

Libraries can be reused and mixed, chunks edited or deleted, retrieval is hybrid with rerank, and API-based knowledge bases are supported.

More advanced orchestration debugging is still on the roadmap.

Operators also get centralized chat history with data annotation and app operation logs.
