The pipeline uses Google Document AI for parallel OCR across all PDF pages simultaneously, Google Translate API with automatic retries, Gemini for context-aware LLM cleanup, and Pydantic for schema validation of LLM outputs. Temporal's durable execution model means if any step fails mid-pipeline, it resumes from that point rather than restarting entirely. The full pipeline processes a 20-page manual in ~50 seconds for about 43 cents. The resulting static site is version-controlled JSON/HTML served from a CDN, allowing community members to submit translation corrections via pull requests. ## Full article daily.dev links to this article rather than hosting it.
