According to the official Google DeepMind blog, Gemini 4 Hydrogen is rolling out gradually to developers, enterprise users, and consumer services, with a focus on the rapid execution of everyday programming and agentic workflows. The company stated that it features unified pricing within its 1-million-token context window, priced at $1.50 per million input tokens and $7.50 per million output tokens, and offers four thinking tiers: low, medium, high, and xhigh, with high set as the default. The rollout spans Google AI Studio, the Gemini API, Gemini for Business, the Gemini app, and Search, while being made available in Google Antigravity to Google AI Pro and Ultra paid subscribers. Model capabilities and efficiency metrics were disclosed by the company, and the rollout scope does not imply that all access points are entirely free.
