English → Wolof Marian / Candle (Malinali)

Public on-device pack for Malinali. Fine-tuned MarianMT weights in safetensors form plus fast tokenizers for Candle (marian_flutter).

Upstream credit

• Fine-tune: LocaleNLP/eng_wolof (MIT)
• Base model: Helsinki-NLP/opus-mt-en-mul
• Base project: Helsinki-NLP / OPUS-MT

Malinali only repackages the root weights and converts SentencePiece to Hugging Face fast tokenizer JSON. We do not claim ownership of the trained model.

This pack is a dedicated English→Wolof fine-tune of opus-mt-en-mul, not a general multilingual model. Always prefix >>wol<< on the source text (token id 1136). Malinali sets sourcePrefix in the catalogue.

Tokenizer

source.spm, target.spm, and vocab.json are the opus-mt-en-mul pair (vocab size 64110, pad id 64109). >>wol<< is id 1136. tokenizer_config.json still says target_lang: mul; do not trust that label — pin Wolof via the prefix.

Files (required)

File	Role
config.json	Marian config

Direction: English → Wolof.

Quality

Upstream self-reported BLEU 76.12 on their custom ~84k English–Wolof dataset. Malinali shows this as BLEU 76.1 / 100. This is not an OPUS / SacreBLEU score computed by Malinali.
