This pull request enhances the document translation workflow by
switching to the new GPT-4.1 model. The generator script’s prompt now
includes a “workflow” section that guides the model to iterate
self-reviews on its outputs to autonomously achieve the highest quality.
This addition has noticeably improved the naturalness and consistency of
the wording in the translated outputs.
This is a pretty minor improvement to the docs: `model_settings`
parameter is only mentioned on the agent doc page, but first-time
visitors may want to know it’s also available on the models page.
