Google is rolling out Gemini 4 Argon in the Gemini app and Antigravity, but access is restricted to paid tiers. Argon excels at solving spatial problems in 3D environments and is now available today for Gemini app users on AI Pro ($20/mo) and AI Ultra (starting at $99/mo) plans. Free users remain limited to Flash-Lite models, continuing Google’s trend of reserving advanced AI for subscribers.
In Antigravity and AI Studio, Argon is available exclusively to AI Ultra subscribers due to the high compute demands of code generation and multi-threaded agentic workflows. While Pro users can use Argon in Gemini app’s Canvas mode for code generation, the more intensive workflows in Antigravity are likely too costly for lower tiers. Google confirms Gemini 3.1 Pro will remain available for those needing more capability than Flash models.
For API users, Argon tokens are priced at $2 per million input tokens and $10 per million output tokens, with a 95% discount on cached tokens—valid only through November 30, after which rates increase to $4 and $20 respectively. Developers are advised to account for these costs when building workflows around the new model.
