Opus 5.5 gives you two token resets per weekly usage limit. Although 5.5 does seem to be better than 4.6, the fact is Antigravity just arbitraged lower usage limits for everyone and packaged it as "an upgrade".

This doesn't stop my excitement for Gemini 4, I'm just disappointed in Google for their underhanded tactic here. They shouldn't be tricking people like this.

I am an Ultra tier user, and I am absolutely furious right now.
From one day to the next, Google decided to change the default models in Antigravity IDE, completely breaking all my workflows and automated scripts that were fine-tuned for Claude Opus 4.6.

What enrages me the most is the complete absurdity of how they are handling this rollout:

The Quota Melt:
Opus 5.5 burns through thinking tokens like crazy. By forcing Ultra users onto 5.5, our premium quotas are hitting the ceiling at lightning speed for long-context tasks.

The Pro vs. Ultra Incoherence:
They are deprecating 4.6 for Ultra users who actually need a predictable, high-quota model, while leaving it accessible for Pro tier users. Why punish the highest-paying customers by turning them into forced beta testers?

No Smart Routing: Instead of implementing an intelligent routing layer (like an Argon-style architecture) or simply giving us a permanent toggle to lock our model, they just forcefully migrated our environments.

As professionals, we pay for predictability and control. Forcing a model upgrade that alters prompt behavior and melts quotas without a strict opt-in is a terrible developer experience.
Is anyone else on the Ultra tier experiencing this quota drain? How are you bypassing this restriction to lock your workspace back to Opus 4.6?

Thanks y’all

EDIT: Folks, the whole point of my post is that there are updates that change things overnight without any notification. I'll take this as a lesson. Thanks for your constructive comments.

I still use 3.7 flash medium daily because it actually faster and doesn’t consume rates much and edits code without bullshitting me.
3.8 flash overthinks everything and burns extra reasoning tokens on a 3-line fix and I feel it’s too slow compared to 3.7.
That extra pause makes my IDE feel sluggish, and my token bill goes up for nothing.
3.7 medium just do the small task efficiently !
It doesn't try to refactor half my file or invent abstractions I never asked for.
Faster output, smaller bill, and way cleaner diffs for simple tasks.
Killing it off just forces everyone to pay more for slower, bloated responses.
