CraftGPT
by ahtism
CraftGPT lets a player send a prompt to ChatGPT from inside the game, without leaving Minecraft, on the Fabric loader.
What it does
The mod is completely client-sided, so a player adds it to their own game and a server does not need it. Players enter an API key in the config file, and Mod Menu can open that config as well. A second option changes which model the AI uses. The default is the cheapest one, while more expensive models give more accurate responses. Responses come back in the game window, and the AI remembers what was said earlier in the conversation.
The chat is set up to answer questions about Minecraft and works as an assistant for building and playing. It can read information about the held item and about the block entity being looked at, so a question can refer to what is on screen. The model is trained on data up to October 2023, so it has no knowledge of recent game releases. Generating a response freezes the game until it finishes, which the author states is probably unfixable.
CraftGPT requires Fabric API, Fabric Language Kotlin and oωo (owo-lib) to run. It is published for Fabric only, in 2 release versions for 1.21 – 1.21.1, and its latest file is 1.2.0 for 1.21.1. The mod is released under the MIT License and is not open source.
Key features
Client-only install
The whole mod runs on the player's client, so a server can stay vanilla and players need nothing extra beyond this mod.
Prompting from in-game
A prompt can be sent to ChatGPT while the player stays in the world, with no need to switch to a browser.
Model selection
A config option changes which AI model answers, letting a player trade cost against accuracy.
Held item and block context
Information about the currently held item and the targeted block entity can be passed along with a question.
Conversation memory
The AI keeps what was said earlier, so follow-up questions refer back to the earlier answers.
