Kind: release · Impact: high

## In brief

- Google launched Gemini 4 Hydrogen on 2026-11-12, available in AI Studio, the Gemini API, Google Search, and paid AI Pro and Ultra tiers in Antigravity.
- Hydrogen is priced at $1.50 per 1M input tokens and $7.50 per 1M output tokens.
- Hydrogen replaces the Flash series, and The Decoder reports it outscores the larger Argon model on the Artificial Analysis Intelligence Index.

## Why it matters

Developers using the Gemini API or AI Studio get a new model with published per-token pricing, and teams relying on Flash models will need to evaluate the replacement. Vercel AI Gateway also lists the model.

## What to do

- Evaluate Gemini 4 Hydrogen against your current Flash or Argon model if you rely on those for cost or latency reasons.
