Overview
- Google rolled out Gemini 4 Argon on Tuesday, Oct. 13, making the model available to developers through the paid Gemini API and to Google AI Pro and AI Ultra subscribers in the Gemini app and Search.
- The API launches at an introductory rate of $2 per million input tokens and $10 per million output tokens through Nov. 30, after which prices double and the model enforces a single 1 million‑token budget that counts both input and output.
- Access is gated: Argon is limited to paid tiers for general users, reserved for AI Ultra in Google Antigravity for agentic coding, and Google is expanding its Fairwind program to give vetted cyber defenders an unguarded version.
- Google cites internal wins — faster engineering refactors, fewer code rollbacks and benchmark leads such as the Vals Index and an 87% embodied reasoning score — while independent tests show mixed results and prediction markets currently favor Google in October.
- The rollout could lower token costs for heavy users during the promotional window, speed multi‑step enterprise workflows if quality holds up, and intensify scrutiny of safety controls as firms and regulators watch how Argon is used in security and science.
