Google opened Gemini 4 Argon to everyone who pays for it.
On Tuesday Google opened its flagship model Gemini 4 Argon to developers and to Pro and Ultra subscribers worldwide. Developers pay $2 per million input tokens until 30 November, and then the price doubles. An independent ranking puts it level with OpenAI's best model but below Anthropic's top one.
Why it mattersFree Gemini users still cannot pick Argon, so trying it means a paid plan. If you build on it, plan your budget for the December price rise now.
