Gemini 3 Pro Image Preview - Persistent Timeout Issues (Tier 1 Paid Account)

Gemini API
, ,
1

I’m experiencing consistent timeout failures when using gemini-3-pro-image-preview

for image generation via the @google/genai SDK. This issue persists even on a Tier 1 paid account, making the model unusable for production workloads.

Environment

  • SDK:

    @google/genai

    v1.38.0

  • Model:

    gemini-3-pro-image-preview

    (Nano Banana Pro)

  • Account Tier: Tier 1 (Pay-as-you-go)

  • Region: Europe

Issue Description

Every API call to gemini-3-pro-image-preview hangs indefinitely. I have implemented a 90-second client-side timeout, and the API consistently fails to respond within this window.

  • Unreliable Service: Paying for Tier 1 but unable to access the premium model.

  • Production Blocked: My app depends on the reasoning capabilities of Gemini 3 Pro and image generation.

  • Negative UX: Users are waiting for minutes only to get a fallback image or an error.

Any solution?

Thanks

Manuel
