Firefox Translations models — mirror for Pisar
Unmodified copy of Mozilla Firefox Translations models used by Pisar (Pozdnekov Labs) for on-device translation. Authors: Mozilla and the Bergamot project. License: MPL-2.0, same as the originals.
Files are the originals from Mozilla's model registry (db/models.json, generated 2026-11-09T00:45:24Z), un-gzipped; SHA-256 match Mozilla's uncompressedHash.
Each pair folder holds model.*.intgemm.alphas.bin, lex.*.s2t.bin (lexical shortlist) and vocab.*.spm.
Run with bergamot-translator, gemm-precision: int8shiftAlphaAll.
Pairs without English translate through English. models.json lists files, sizes and hashes.
