Days of 503 overloaded or 504 etc on images, YouTube lookups

Gemini API

Hello everyone,

Paid tier 1, project in Cloud, billing set up, etc.

It’s not usable like this, even for me to build something, never mind a product for a client. The exception this week appears to be that it works, but when seems to be completely random.

Simplest test prompt possible for one basic image. Run it through 3 models. gemini-3-pro-image-preview and nano-banana-pro-preview, the ones we would actually like to use for the project, of course, are just returning 504 or 503 errors.

How can Google have overload problems for a few api images? It’s Google.

Any help appreciated. [EDIT: happy to use Vertex or whatever if there are actually live working api versions of the top models somewhere else I am unaware of]
