Google DeepMind announced Gemini 4 Hydrogen on 12 Nov 2026. The model is rolled out globally for developers, enterprises and consumers through the Gemini API, Google AI Studio, the Gemini app and Search. Hydrogen is built for quick execution and costs $1.50 per million input tokens and $7.50 per million output tokens. It runs 2.5 × faster than Gemini 3.8 Flash and scores higher on several developer benchmarks. The model also powers the new Orchestrator feature that switches between Hydrogen and larger Gemini models.
Why it matters
Developers can accelerate coding and testing workflows while paying lower token fees.
