Google has launched Gemini 4 Hydrogen, a high-speed and efficient model for everyday coding and agentic workflows, succeeding Gemini 3.8 Flash and immediately available to all users. It supports a full 1 million token context window, priced at $1.5 per million input tokens and $7.5 per million output tokens, with no tiered pricing and a 95% discount on cached input.

Hydrogen forms a tiered product matrix with Carbon and Argon, which focus on deep reasoning, and introduces a new xhigh reasoning level above high. It tops 7 of 10 benchmarks published by Google, with Terminal-Bench 4.1 score jumping from 18.2% to 57% and 2.5x faster task completion at default high thinking level. On the Artificial Analysis Intelligence Index, it scores 54, just 1 point behind Claude Sonnet 5.5 and GPT-6.1 Sol, while costing about 32% of Sonnet. The accompanying Orchestrator dynamically switches between Carbon and Hydrogen, reducing average quota consumption by 24%.

Hydrogen is fully integrated into Google AI Studio, Gemini API, Gemini for business, the Gemini app, and Google Search, and is available to paid AI Pro/Ultra subscribers. Its cost-effectiveness and speed are poised to lower the barrier for agentic workflow development, intensifying competition with Anthropic and OpenAI in the mainstream model race and driving broader AI adoption.

LATEST/Google released Gemini 4 Hydrogen, its third new model in six weeks, introducing the xhigh reasoning tier and scoring 54 on the Artificial Analysis Intelligence Index, just 1 point behind Claude Sonnet 5.5 and GPT-6.1 Sol. It fully replaces 3.8 Flash and debuts the Orchestrator feature that dynamically switches between Carbon and Hydrogen, reducing average quota consumption by 24%.

    • Hydrogen replaces Gemini 3.8 Flash, forming a three-tier Gemini 4 lineup with Carbon and Argon for everyday coding and agent work
    • API pricing is $1.5/$7.5 per million input/output tokens, cheaper than Sonnet 5.5 but pricier than GPT-6.1 Terra
    • It leads 7 of 10 Google-published benchmarks with 13.5% on SWE-sweep, but trails Sonnet 5.5 on Terminal-Bench and OSWorld
    • Per-task cost at max setting is about $3 versus roughly $10 for Sonnet 5.5 at similar scores, while Terra is cheaper but scores lower
