Google Launches Gemini 4 Argon With 1 Million Token Context

Google has made Gemini 4 Argon globally available, the company said in a blog post. Developers and enterprises can use it through the API in AI Studio and the Gemini platform, Google AI Ultra subscribers can use it in Google Antigravity, and Ultra and Pro subscribers get it in the Gemini app and AI Mode in Search. The release follows Google's introduction of the model earlier this month, when access started with a limited rollout.

The model launches at an introductory price of $2 per million input tokens and $10 per million output tokens, with cached input tokens at 95% off. Google says Argon outperforms other frontier models on benchmarks across domains and ranks first on the Vals Index, which measures performance in sectors such as finance, coding, legal and tax work.

According to the model card from Google DeepMind, Gemini 4 Argon is a new frontier model rather than a fine-tune of a prior model: a sparse mixture of experts transformer with native support for text, image, audio and video input and a combined input and output context window of up to 1 million tokens. Google says that inside the company, Argon in Antigravity helped teams increase agentic code submissions by more than 35% while reducing code rollbacks by nearly a third.
