**Issue Overview:** I am encountering a persistent connectivity error while using the **Gemini 3.7 Flash High** agent on Antigravity. I am an active **Pro Plan** subscriber.

**Error Message:** `"Model unavailable, retrying in 3s (attempt 2/9), Agent execution terminated due to error."`

**Steps to reproduce / Behavior:**

1. Select the `Gemini 3.7 Flash High` agent/model.

2. Submit any prompt.

3. The request hangs and enters an infinite retry loop without ever completing.

4. **Workaround:** Changing the agent/model to a different one immediately resolves the issue and prompts are processed normally.

**Environment Details:**

- **Account Tier:** Pro Plan

- **Affected Model/Agent:** Gemini 3.7 Flash High

It seems like the request pool or API route for this specific high-reasoning agent is hitting a bottleneck or server-side failure.

I have attached a screenshot showing the error interface. Any insights or fixes from the team would be greatly appreciated!

Hi @bito_bobli,

Thanks for the screenshots! “Model unavailable” means Gemini 3.7 Flash High couldn’t respond at that moment. That’s on our side, not your account, which is why switching models works.

I also noticed this conversation is quite long (2 days, with many steps), and you’re asking it to continue. Very long conversations can sometimes keep failing on one model. Please try:

1. **Start a new conversation** with Gemini 3.7 Flash High, give a short summary of where you left off, and continue from there.
2. **If it still fails,** use another model for now and try High again later.
3. **Update Antigravity** to the latest version.

If the new conversation hits the same error too, let us know!.
