NLLB-200 3.3B
Full-size No Language Left Behind model for 200-language translation.
About
NLLB-200 3.3B is the full-size model from Meta's No Language Left Behind project, released in July 2022. The encoder-decoder model translates across more than 200 languages, with 3.3 billion parameters making it the most accurate variant of the NLLB-200 family.
It is one of Hugging Face's most-downloaded translation model families, supported by Transformers, CTranslate2 and llama.cpp, with GGUF builds for local inference. The weights are released under a non-commercial license (CC-BY-NC), so production use requires that restriction.
