Google Antigravity Launches 'AI Ultra' $100/Month Tier with Bonus Credits

Google Antigravity has officially announced the launch of its new Google AI Ultra subscription tier. Priced at $100/month, this premium plan is engineered to bring peak frontier performance and substantially higher rate limits to professional developers running intensive AI workflows.

To celebrate the launch, Google is also running a limited-time promotion: new Ultra subscribers will receive $100 in bonus credits to act as a buffer if they exceed their monthly quota limits.

What is Included in the $100/Month Google AI Ultra Plan?

The Google AI Ultra tier is designed specifically to address the heavy token demands of autonomous agent loops (such as Antigravity's Planning Mode and multi-subagent delegation).

• Higher Usage & Rate Limits: Runs deep code search, parallel testing, and multi-file code replacement tasks concurrently without hitting API rate-limit caps.
• Frontier Performance: Provides prioritized routing to Gemini 1.5 Pro and Gemini 1.5 Flash models, ensuring ultra-low latency (TTFT) and high reasoning precision.
• Quota Buffer (Limited Time Offer): A $100 bonus credit automatically kicks in if you exhaust your plan's standard monthly limits, ensuring zero downtime in your development flow.
• Bundled Ecosystem Extras: The subscription also integrates with Gemini App Limits, Google Flow, YouTube Premium, and 20TB of cloud storage.

Why This Matters for Antigravity Workflows

When running complex coding tasks via Antigravity 2.0, the CLI agent frequently invokes parallel subagents for repository research and runs iterative test validations. Under the free or standard tiers, heavy codebases could occasionally trigger rate-limiting.

The Google AI Ultra tier directly solves this bottleneck, offering enterprise-level reliability for solo developers and startup engineering teams who want to delegate entire coding sprints to autonomous agents.
