Gemini 3 Pro Image Preview returning persistent 503 errors despite enabled billing

[AIKIZI_Team]

We’ve been experiencing persistent failures with the Gemini 3 Pro Image Preview model over the past 24–48 hours.

Initially, requests were failing with 499 errors, and they’ve now escalated to consistent 503 (model overload). This is happening despite billing being enabled, usage well within documented limits, and operating as a Tier-1 user.

Details:

• Model: Gemini 3 Pro Image Preview

• Errors observed: 499 → 503

• Region: South India

• Billing: Enabled

• Usage limits: Not exceeded

• Impact: Production image generation workloads are timing out or failing entirely

From logs, the failures appear to be upstream model capacity or regional availability issues, not client-side errors.

Is this a known outage, regional capacity constraint, or degradation affecting Gemini 3 Pro Image Preview?
If so, is there an ETA, mitigation strategy, or recommended fallback model?

Any confirmation from the Google team would be appreciated, as this is currently blocking production use cases.

yeah similar issue being faced by me i tried to contact google team but also i got no response form them i think this problem is going to take a long time to fix we should start looking for alternative.

This is extremely concerning for a production-ready API. The issue appears to be region-specific underperformance, and while we have temporarily wired a fallback model (SeedDream 4.5) to keep the site running, that is not an ideal or long-term solution.

When teams trust APIs, especially from large providers like Google that actively encourage production adoption of AI models, there is an expectation of baseline reliability and capacity transparency. It is not acceptable for production websites to experience sustained failures like this, particularly when billing is enabled and access is via a company account.
