Google launches Gemini 4 Hydrogen for Pro and Ultra users
Hydrogen costs $1.50 per million input tokens and $7.50 per million output tokens, with flat pricing across its 1 million-token context window.
The rollout spans Google’s developer, business, consumer and Search products, with Antigravity access for paid Pro and Ultra subscribers. Four thinking levels let users trade quality against latency and cost. Google says Hydrogen runs 2.5 times faster than Gemini 3.8 Flash at its high setting. Ultra subscribers also get Antigravity’s Orchestrator, which pairs Carbon’s planning with Hydrogen workers; Google reports near-Carbon task success using 24% less quota and finishing 19% faster on Terminal-Bench 4.0.
