MCChatGPT
by Bawnorton
MCChatGPT brings a ChatGPT chat interface into Minecraft, letting a player ask questions to an OpenAI model from inside the game.
What it does
Players authenticate with an OpenAI API key, which is obtained from the OpenAI account page and then entered through the mcchatgpt-auth command. Once a key is set, the ask command sends a question to the model and returns its reply in the chat window, and the model can keep the last 10 messages as conversational context.
The setcontextlevel command controls how much information about the world the model receives with each request. Higher context levels give the model more detail about the player and surroundings, but each API request then costs more to send, so the default level is a balance between usefulness and cost. The model's training data ends around the release of the game's later updates, so it may not know about newer game content.
MCChatGPT is a client-side mod, so only the player's game needs it and servers run without it. It requires Fabric API and is published for Fabric and Forge, with files covering 1.18.2, 1.19.2, 1.19.3 and 1.19.4. The latest file is 0.2.1 for 1.19.4, released on 2023-04-24, and the code is open source under the MIT License.
