Project information

NLLB-Translate: Multilingual Translation Service

Containerized translation service built on Meta's NLLB-200, providing translation between any pair of 202 languages via CLI and an OpenAI-compatible HTTP API. Built with FastAPI and facebook/nllb-200-distilled-600M. Features Docker deployment, model caching, health checks, an interactive client, and a regression suite that measures real translation quality.

Key Features: • 202 languages from a single loaded model, direction chosen per request • CLI and HTTP server interfaces • OpenAI-compatible /v1/chat/completions endpoint • Docker containerization with multi-stage builds • Automatic model downloading and caching • Interactive test client included • Environment-based configuration

Sibling project to opus-translate, which does German→French with one small model per direction.
