Users protest as Google Antigravity price floats upward

Developers using Google's Antigravity agentic AI coding tool are complaining about higher prices following an announcement yesterday that the company is evolving its AI plans.

The company posted to X that it is "evolving Google AI plans to give you more control over what you can build."

According to the new post, AI credits can now be used for Antigravity, with subscriptions providing some built-in credits while further credits are available for purchase as needed, at a cost of $25 for 2,500. Exactly what a credit is worth when used with Antigravity is not described in the documentation.

Google's AI for Developers forum is filled with complaints, especially from those with AI Pro ($20.00 per month) subscriptions. According to the plan description, still current at the time of writing, AI Pro plans offer a "high, generous quota, refreshed every five hours until weekly limit reached." However, users report that this appears to be no longer the case (other than with the cheapest model), with a weekly wait between refreshes, rather than five hours, during which time they cannot continue work without purchasing credits or upgrading the plan.

Antigravity supports five LLMs (large language models): these being Gemini 3.1 Pro (with High and Low options), Gemini 3 Flash, Anthropic Claude Sonnet 4.6 or Claude Opus 4.6, and OpenAI's GPT-OSS 120B. Flash is the cheapest model, tuned for efficiency. With its latest post, Google states that the Pro plan is suitable for "hobbyists, students and developers who live in the IDE," as opposed to relying on agents, and that these users can use Flash as a "taste test" for more advanced models. Professional developers are pointed towards the AI Ultra ($249.99 per month) plan, for "consistent, high-volume access to our most complex models."

On Reddit, a developer on AI Pro who has tracked their token usage posted that "before January I could use over 300 million input / 1-2 million output in a week for the Gemini Pro models," but that "this week I hit my weekly rate limits at less than 9 million input / 200 thousand output tokens."

Antigravity was launched in preview in November 2025, at which time pricing was not yet announced. The company soon pointed users towards its Google AI Pro and Ultra subscriptions, using vague terms such as "high", "generous" and "meaningful" to describe quota limits. This wording makes it hard to know the actual limits and how they may change.

Although the latest post appears to indicate new pricing, complaints about unexpected quota drops and inadequate limits are not new.

"Unacceptable Antigravity Quotas for Gemini 3.1 Pro – Workflow Completely Blocked" said another developer towards the end of last month. "We need a transparent explanation of how these Antigravity quotas are calculated and an immediate fix for these ghost-drains on our limits."

AI processing makes intensive use of compute resources, and how much resource will be used by any one prompt is unpredictable, making pricing a difficult problem for both users and providers. Another unknown is the extent to which providers are willing to subsidize users while building market share, though we have seen sudden, sharp increases in prices before.

We have asked Google to clarify what has changed and what an AI credit buys, when used with Antigravity.
