FastAPI lets LLMs drive its translations

The FastAPI project's translation pipeline is now almost fully automated by LLMs, and it's shipping five updates in a single day.

FastAPI's docs are getting a machine-driven refresh, with five PRs from the pr-submit bot updating Hindi, Russian, Traditional Chinese, Ukrainian, and German translations [1][2][3][4][5]. Each PR was "created automatically using LLMs," using a prompt file to generate the translations rather than manual edits [1]. The bot itself recommends that contributors update the llm-prompt.md file for better results instead of submitting changes directly [1]. This approach scales translation maintenance across multiple languages with minimal human intervention, but it also means reviewers should treat these PRs with extra scrutiny since the text isn't handcrafted. The activity totals show 22 commits and 11 PRs this period, with these five translation PRs leading the repo's momentum. If you maintain a FastAPI docs translation, check whether your language's prompt file is current to keep the automated output accurate.
