Gpt-Assistant
by SPRUT14K_
Gpt-Assistant adds an in-game chat assistant that answers questions through the Mistral AI service, with a settings screen for the API key.
What it does
Players type a question in the Minecraft chat and the assistant replies in the same window, using a Mistral API key that the player enters once in the mod settings. Responses can include multiple lines, and an option turns off the removal of text formatting so replies keep their original layout.
The API key is set up by opening the Gpt-Assistant screen from the Mods menu, pasting the key, and pressing Verify. The mod checks the key and shows a warning in the chat when no valid key is saved. The mod needs Fabric API and Mod Menu, and it is published for Fabric only.
Servers do not need it; each player installs it for their own game. The code is not open source; it is released under All rights reserved.
