Introduction of opus-mt-fr-en-GGUF

Model Details of opus-mt-fr-en-GGUF

Opus-MT French → English — GGUF (ggml)

GGUF / ggml conversion of Helsinki-NLP/opus-mt-fr-en for use with CrispStrobe/CrispASR ( --backend marian ).

A small (~75M parameters, 6+6 layers, d=512) MarianMT model for one language pair. In CrispASR these are the fastest translators for live transcription + translation ( --live-translate ).

Licence and attribution

CC-BY-4.0. The weights are the opus-2020-02-26 release of the OPUS-MT project (Jörg Tiedemann and Santhosh Thottingal, University of Helsinki; OPUS-MT — Building open translation services for the World , EAMT 2020), trained on OPUS data. The project distributes its pre-trained models under CC-BY 4.0 ( Opus-MT README , OPUS-MT-train README ); that statement, not the tag on an individual model card, is what this repository follows. This is a format conversion: the weights are unchanged at f16 and quantized at q8_0. Redistribution requires attribution to the OPUS-MT project.

Files
File Size Output vs. the reference implementation
opus-mt-fr-en-f16.gguf 155 MB 8/8 sentences identical greedy, 8/8 with beam 4
opus-mt-fr-en-q8_0.gguf 85 MB 8/8 sentences identical greedy — any others differ in wording. Fastest; recommended.

"Reference" is MarianMTModel.generate from Hugging Face transformers on the original checkpoint, on 8 test sentences; input token ids were identical for 8/8.

Quick start
git clone https://github.com/CrispStrobe/CrispASR && cd CrispASR
cmake -B build -DCMAKE_BUILD_TYPE=Release && cmake --build build -j

# Text → text. -bs 1 is greedy; without it the checkpoint's own beam size is used.
./build/bin/crispasr --backend marian -m opus-mt-fr-en -sl fr -tl en -bs 1 \
    --text "Bonjour et bienvenue à la réunion d'aujourd'hui."
# Hello and welcome to today's meeting.

# Live: microphone in, transcript + translation out, sentence by sentence
./build/bin/crispasr --live-translate -l fr --tr-tl en \
    -m auto --backend parakeet --translate-backend marian

-m opus-mt-fr-en downloads opus-mt-fr-en-q8_0.gguf on first use. The recogniser in the live example must support French.

Notes
  • One model per direction; the opposite direction, where one exists, is cstr/opus-mt-en-fr-GGUF .
  • Live mode always decodes greedy.
  • Literal </s> , <unk> , <pad> in the input are treated as ordinary text here (the reference treats them as special tokens).
