Google opens Gemini 4 Argon to everyone with a 1M-token limit

Google has opened Gemini 4 Argon, its latest frontier AI model, to a broad audience. Developers and enterprises can use it through the Gemini API in AI Studio and on the Gemini platform. Google AI Ultra subscribers get it in Google Antigravity, and Ultra and Pro subscribers can try it in the Gemini app and AI Mode in Search.

What Google claims

Google says Argon is built for hard, multi-step work in coding, finance, legal, cybersecurity and science. It ranks #1 on the Vals Index, a benchmark Google cites for performance across those economic sectors. Via the API, Argon offers an industry-leading 1 million unified input-output token limit.

Inside Google, Argon in Antigravity has reportedly raised agentic code submissions by more than 35% and cut code rollbacks by nearly a third. Google also describes Chrome refactoring, Agent Development Kit speed-ups and open-source science package improvements as early wins.

Pricing

Argon launches at an introductory $2 per million input tokens and $10 per million output tokens, with cached input at a 95% discount. After 30 November 2026, Google says public-access Argon moves to $4 / $20 per million input/output tokens.

Who can use it

• Developers: Gemini API paid tier in AI Studio and Android Studio; Ultra users also in Antigravity.
• Enterprises: Gemini for business, the API and Antigravity.
• Consumers: Gemini app and AI Mode in Search for AI Ultra or Pro.
• Scientists: Google is offering up to 10,000 researchers Antigravity’s highest usage tier free for six months (eligibility and capacity apply).
