Nllb
App in the BluixApps catalog
What it is
NLLB-200 (No Language Left Behind) is Meta AI's neural machine translation model — translates across 200 languages including 150+ low-resource ones. The most comprehensive open translation system, particularly valuable for languages underserved by Google Translate / DeepL.
When you need translation for languages outside the top 30, NLLB is often the only good option.
What it's for
- 200-language translation — broad coverage
- Low-resource languages — indigenous, regional, African dialects
- Batch document translation — privacy-preserving alternative to commercial APIs
- API-driven workflows — programmatic translation at scale
- Multi-lingual content production for catalogs, support, education
Who it's for
- NGOs working with indigenous languages
- Educational platforms offering multilingual courses
- E-commerce platforms translating product catalogs to many markets
- Operula translating artisan content across cultures
- GuardianPlug Alexa skill translating intent data
- Hosting providers offering translation tier
Why teams pick NLLB over alternatives
- Distilled variants CC-BY-NC 4.0 (research/non-commercial)
- Full models CC-BY-NC 4.0 for now (CTranslate2 community port has commercial-friendly fork)
- 200 languages — broader than DeepL (33), competitive with Google
- Low-resource excellence — primary use case advantage
- Meta backing — well-funded research
- Privacy-preserving vs commercial APIs (your data stays on your server)
- No per-character pricing at scale
Integrations
- Gradio web UI included
- HuggingFace Transformers native
- FastAPI wrapper for production REST
- Pair with: Surya OCR (image → text → translate)
- Pair with: WhisperX (audio → transcript → translate)
- Pair with: BluixApps catalog (translate descriptions to 18+ languages)

Tips & operations
- Model variants:
- nllb-200-distilled-600M (default, 4 GB VRAM)
- nllb-200-distilled-1.3B (better quality, 8 GB VRAM)
- nllb-200-1.3B (full, 8 GB VRAM)
- nllb-200-3.3B (best quality, 16 GB VRAM)
- Language codes: FLORES-200 codes (eng_Latn, ita_Latn, ara_Arab, etc.)
- VRAM: scales with model size
- Speed: ~50-100 tokens/sec on RTX 4090 (distilled-600M)
- Quality: matches DeepL for major EU pairs, exceeds Google for many low-resource
- Production: FastAPI wrapper recommended over Gradio for high throughput
- License caveat: distilled = research; for full commercial use CTranslate2 community port may be cleaner
