Firefox Translations models (mirror)

A byte-for-byte mirror of the translation models Mozilla ships in Firefox (mozilla/translations), made for runonweb (runonweb/translate). Mozilla's buckets send no CORS headers, so browsers can't load the models from there directly.

• 106 direct pairs between English and 58 languages, the architecture Firefox ships in release for each pair (base-memory > base > tiny). int8 Marian NMT students, 17–44 MB per pair.
• Files are gunzipped; nothing else is changed. Each <pair>/ holds the model, the shortlist (lex) and the SentencePiece vocab(s). runtime/ holds the Bergamot WASM runtime (@mkljczk/bergamot-translator 0.4.16).
• index.json lists the hosted pairs. Revisions and checksums come from Mozilla's model registry; the SDK requests <pair>/<file>?rev=<revision>.

Regenerate with node scripts/translate-models.mjs fetch --all in the runonweb repo.

Use

import { Translator } from 'runonweb/translate'

const t = new Translator({ from: 'en', to: 'es' })
const { text } = await t.translate('Hello world')
