[Bug] Omni 1.1 video generation fails on Agent Platform with "AgentPlatform quota exhausted" while Omni 1.0 previously worked

Gemini API
1

Hello,

I would like to report a possible issue with Omni 1.1 video generation.

Before the Omni 1.1 update, I was able to successfully generate videos through Gemini Enterprise Agent Platform using Omni 1.0.

However, since Omni 1.1 was released, I have not had a single successful video generation through Agent Platform.

Every attempt fails with the following error:

“AgentPlatform quota exhausted”

My Google Cloud free trial is still active, with approximately 40,000 JPY worth of trial credits remaining. The trial is also close to expiration, with approximately 2 days remaining.

I also tested Omni 1.1 video generation through Google AI Studio.

To use the API project through AI Studio, I enabled billing by adding approximately 1,000 JPY.

After enabling billing, Omni 1.1 video generation through AI Studio succeeded once.

The usage for that successful generation appeared to be deducted from my remaining Google Cloud free trial credits.

However, after that single successful generation, AI Studio video generation also stopped working.

When attempting to generate a video, the AI Studio page fails during generation and needs to be reloaded.

At the same time, video generation continues to work normally through other Google interfaces:

  • Gemini Web: Working normally
  • Google Flow: Working normally

So the current situation is:

  • Agent Platform + Omni 1.0: Previously worked
  • Agent Platform + Omni 1.1: Never succeeded; consistently returns “AgentPlatform quota exhausted”
  • Google AI Studio + Omni 1.1: Succeeded once, then stopped working and the page fails during generation
  • Gemini Web: Working normally
  • Google Flow: Working normally

Because Agent Platform worked with Omni 1.0 but has not succeeded even once with Omni 1.1, while Gemini Web and Google Flow continue to generate videos normally, I am wondering if there may be an issue related to quota provisioning, entitlement, billing/trial credit routing, or backend configuration for Omni 1.1 on the API / Agent Platform side.

Could you please confirm whether this is a known issue, or advise what I should check on my project/account side?

I can provide screenshots, timestamps, model names, or additional error details if needed.

Thank you.
