3 Key Points

What happened
Gemini 4 Argon is rolling out today in the Gemini app for AI Pro ($20/mo) and AI Ultra (starting at $99/mo) subscribers. In Antigravity and AI Studio, it is limited to AI Ultra.
Why it matters
Free users lose access to the newest model, and Google has declined to say when or if Argon will reach Antigravity on other tiers, so developers may need to weigh higher-tier plans.

WHO IT HITSDevelopers building coding workflows on Google's models and subscribers weighing AI Pro versus AI Ultra face higher costs and plan restrictions. Teams using Antigravity for multi-threaded agentic workflows must be on AI Ultra.

Context & Analysis

Google's decision to restrict Gemini 4 Argon to paid tiers follows its recent move to limit free users to Flash-Lite after pulling back Flash models. The company is keeping Gemini 3.1 Pro available for those who need more capability than Flash. For coding-focused products, the split is sharper: Antigravity and AI Studio require AI Ultra, while the Gemini app's Canvas mode allows Pro subscribers to generate code. Code generation has grown more important since Google's last Pro model release, but it consumes significant compute, which may explain the tiering. Google has not said whether Argon will reach Antigravity on lower tiers. For developers using the paid API, introductory token pricing runs through November 30 before doubling, a factor to consider before building workflows around the new model.
