Google Antigravity Quotas Drop 97% as Pricing Model Shifts to Paid Credits

Google has restructured pricing for Antigravity, its agentic AI coding tool launched in preview in November 2025, moving from vague quota guarantees to an explicit pay-as-you-go credits system. The shift has triggered developer backlash over dramatic quota reductions and lack of transparency.

Pricing Structure Changes

Google announced the new pricing model yesterday, introducing AI credits purchasable at $25 per 2,500 credits. The exact conversion rate between credits and token usage remains undisclosed. The company now positions its plans as:

• AI Pro ($20/month): For "hobbyists, students and developers who live in the IDE," primarily for lighter Flash model usage
• AI Ultra ($249.99/month): For "consistent, high-volume access to our most complex models"

Both tiers include built-in credits, with additional credits available for purchase.

Quota Collapse Reported

Developers report severe quota restrictions compared to pre-January 2026 limits. One tracked case shows: previously 300M input tokens and 1-2M output tokens per week; this week, under 9M input and 200K output tokens before hitting rate limits—a 97% reduction in input tokens.

The AI Pro plan originally promised a "high, generous quota, refreshed every five hours until weekly limit reached." According to user reports, this has changed to a weekly refresh cycle with extended wait periods between resets, effectively blocking work without purchasing additional credits or upgrading.

Google's AI for Developers forum shows widespread complaints, with threads titled "Unacceptable Antigravity Quotas for Gemini 3.1 Pro—Workflow Completely Blocked" and demands for "transparent explanation of how these Antigravity quotas are calculated."

Model Support

Antigravity supports five LLM options:

• Gemini 3.1 Pro (High and Low variants)
• Gemini 3 Flash
• Anthropic Claude Sonnet 4.6
• Anthropic Claude Opus 4.6
• OpenAI GPT-OSS 120B

Flash is positioned as the cheapest option.

Transparency Issues

Google launched Antigravity without disclosed pricing in November 2025, using deliberately vague terminology like "high," "generous," and "meaningful" to describe quota limits. The new credits model introduces another layer of opacity: the credit-to-token conversion rate for Antigravity remains unexplained in Google's documentation.

The Register has asked Google to clarify what changed and what AI credits actually purchase when used with Antigravity.

What This Means

Google is shifting AI tool pricing from predictable (if unclear) monthly quotas to consumption-based models similar to API pricing. For AI Pro users, this represents a practical price increase from $20/month to $20+ monthly once quota overages become frequent. The 97% quota reduction suggests Google is either (1) recalibrating usage patterns post-launch, (2) reducing subsidies to improve margins, or (3) deliberately steering users toward the $250/month tier.

The lack of credit conversion transparency mirrors common vendor tactics: ambiguous pricing creates friction that drives tier upgrades. Developers seeking consistent access now face a $250/month commitment instead of $20/month—a 12.5x increase—with no intermediate option for moderate users.
