AI Companion Fabric

By

An autonomous AI companion driven by your own LLM. It navigates, gathers, crafts, builds on request, and fights alongside you. Runs fully local with llama.cpp (nothing leaves your network) or any hosted OpenAI-compatible API. Singleplayer & LAN.

Early-build test run with Grok as the brain. Delightfully derpy, but you can see how the companion thinks and acts. Better models = better behavior (and higher token cost). Local LLMs work too.
Chitty chitty chat chat — just hanging out talking with the companion.
Early proof-of-concept — first working build of the AI companion
The Identity tab: set your companion's name, description, and system prompt to shape its personality, then pick a skin file and toggle slim arms to control its look.
The LLM tab: connect the companion to any OpenAI-compatible endpoint — local llama.cpp or a hosted API like xAI. Set the model, temperature, max tokens, and API key, plus cost guardrails (per-session request cap and periodic token-usage reports).
The TTS tab: give your companion a voice. Toggle it on, point the endpoint at your local Kokoro server (the included docker-compose file starts one), then pick a voice and playback speed. Fully local — no cloud, no API key.
Behavior tab: trigger prefix (respond only when addressed, e.g. @Vetta) and think throttle (minimum seconds between LLM turns). Keeps a chatty server from running up your token bill.
Where to find things in your CurseForge instance: run docker compose up -d in config/aicompanion/tts/ for voice output (enable TTS in the in-game config too), and drop custom skin PNGs into config/aicompanion/skins/.
I'm a solo dev. This mod runs on real AI tokens (local or paid APIs) which aren't free. Donations go straight to covering those costs so I can keep improving it. Even $1 helps more than you think. Thanks for the support!
