deepchat
by wh0oo
Installed on a Fabric server, deepchat connects the in-game chat to the DeepSeek AI service so players can ask questions and receive answers in chat.
What it does
Once a DeepSeek API key is set, chat messages sent through the mod are forwarded to DeepSeek and the replies appear in the same chat window. The mod is server-side only, so players join without installing anything and only the server holds the key. Required dependency: Fabric API must be present on the server alongside deepchat.
A file named api key.txt holds the DeepSeek API key, and the model used for replies can be changed in the configuration. Files are generated on first launch, so the server needs one start before the key can be entered. The code is released under CC0 1.0 Universal, which places it in the public domain and makes it open source, and public source code and an issue tracker are available.
Fabric builds are published for game versions 1.21.5 – 26.2 across nine release versions, with 1.0.3+26.2 for 26.2 as the latest file, dated 2026-06-16. The first public release came on 2025-05-19 and the most recent update on 2026-06-16.

Use cases

Who it’s for: Server owners running Fabric who have a DeepSeek API account and want AI replies in chat. Players on such a server need nothing extra.
