Lingua Imperialis - NLLB-200 models (CTranslate2, int8)

CTranslate2 int8 conversions of Meta's NLLB-200 translation models, used by Lingua Imperialis, a free Warhammer 40,000: Darktide mod that translates in-game chat locally on the player's machine.

These are format conversions only. No retraining, no fine-tuning, no change to model behaviour.

Contents

Folder	Base model	model.bin	Notes
model/	facebook/nllb-200-distilled-600M	622,596,105 B	default; faster, lower memory
model-large/	facebook/nllb-200-1.3B	1,381,827,201 B	higher accuracy

Each folder contains the four files the CTranslate2 runtime needs: model.bin, config.json, shared_vocabulary.json, sentencepiece.bpe.model.

The mod pins the SHA-256 of each model.bin and refuses to load a model that does not match, so these files must not be modified in place.
