As someone who actually had to build on Gemini, it was so indefensibly broken that I couldn't believe Google really went to production with it. Model performance changes from day to day and production is completely unstable as Google will randomly decide to tweak things like safety filtering with no notice. It's also just plain buggy, as the agent scaffolding on top of Gemini will randomly fail or break their own internal parsing, generating garbage output for API consumers.

Trying to build an actual product on top of it was an exercise in futility. Docs are flatly wrong, supposed features are vaporware (discovery engine querying, anybody?), and support is nonexistent. The only thing Google came back with was throwing more vendors at us and promising that bug fixes were "coming soon".

With all the funded engagements and credits they've handed out, it's at the point where Google is paying us to use Gemini and it's _still_ not worth the money.
