Chat LLM Translation
by zamusix
Chat LLM Translation runs a local language model that translates chat messages received and sent on multiplayer servers, between English and Japanese.
What it does
Received messages are translated from English to Japanese and sent messages from Japanese to English, using a generic LLM that operates offline once it is set up. A translation cache built on retrieval keeps earlier results, so repeated sentences appear instantly, and the cache is stored separately for each server. A full cache option can load previous translations when a player joins a server again.
The mod starts the llama-server process automatically when Minecraft launches and stops it on exit, and it fetches the files it needs on first launch. Multi-GPU setups can assign separate GPUs to Minecraft and the language model. Translations take the surrounding conversation into account, and prompt caching speeds up repeated requests.
The mod is a client mod, so servers run without it and players install it alone. It is published for Fabric only, across 12 release versions, with 2.0 for 1.21.11 as the latest file. The code is open source under the MIT License, and Mod Menu is an optional dependency that adds a configuration screen.
Key features
Automatic chat translation
Incoming chat is translated from English to Japanese, and outgoing chat from Japanese to English, without manual steps.
Offline local model
The language model runs on the player's own machine, so translation does not depend on an online service once it is installed.
Per-server translation cache
Translation history is saved for each server, and repeated sentences are returned from the cache instead of being translated again.
Context-aware output
Earlier messages in the conversation are used when translating a new one, which keeps phrasing consistent across a chat.
