Available on the free tier and at paid-tier
[pricing](/docs/pricing#gemini-4-hydrogen) of $1.50 per 1M input tokens and
$7.50 per 1M output tokens, `gemini-4-hydrogen` introduces a fourth
[`xhigh`](/docs/thinking#understanding-thinking-levels) thinking level alongside `low`,
`medium`, and default `high`, and is now the default model for the
[Antigravity agent](/docs/antigravity-agent) in Gemini Managed Agents. See

Brand Impact
On 12 November 2026, Google made Gemini 4 Hydrogen generally available on the Gemini API — a fast, efficient model it is bringing to everyone on the free tier, priced at $1.50/$7.50 per 1M tokens, with a new xhigh thinking level, now the default for the Antigravity agent and the successor to Gemini 3.8 Flash. For brands, the story is the everyday tier getting sharper: Hydrogen is the kind of fast model that sits behind most quick AI answers, so a more capable free-tier model raises the floor on the replies most people actually see. It is an API model, not a placement you can buy — it names brands from the public sources it trusts, so the work is clear, consistent, verifiable evidence. (It is a Gemini API GA, not confirmed as the free Gemini app default or the engine behind AI Overviews.)
