This was the older Gemini 3.7 submission and linked to the blog post; the submission you marked this as a dupe of occurred 20 min after this one, and linked to the much more barren https://ai.google.dev/gemini-api/docs/models/gemini-3.7-flas... URL.
We updated the primary submission's URL with the blog post URL from this one, and made the API doc a secondary link in the thread header.
