The Entity

Once the world is running, the presence reads the player's vitals, pack contents, position and latest actions, then reacts as they happen. Its behavior follows a personality set in configuration, so it can quietly guide a player toward safety, or unsettle them with phantom sounds and attempts to harm them.

The mod needs a language model to function, and polling a paid API for game state gets expensive quickly, so the author suggests a free option such as Groq or a local model run through llama.cpp. The model should be at least 8B parameters, and larger 27B or 35B models give stronger awareness of the situation if the hardware can hold them. Players set the model's context window to at least 16384 so it can remember recent game history and inventory state, and switch reasoning off so the model does not loop over its own internal deliberation.

The Entity is released under the MIT License, and its source code is public. It is Client and server, so the server and every player need it, and it requires Cloth Config API and Mod Menu. Files are published for Fabric only, for 1.21.11 only, with 1.0.0 as the latest file from 2026-03-12.
