Summary
According to a post on X by @arena, Gemini 4 Hydrogen is the fastest model in Arena's Agent Arena top 10, with a typical step taking 7.3 seconds. The post says this is about 2.7 times faster than Claude Sonnet 5.5 and 3.1 times faster than GPT-6.1 Sol. The model is now widely available on Google Cloud, according to launch partner Parallel, and has been added to the Antigravity CLI. One demo in the post ran 16 parallel Hydrogen builders under a Gemini 4 Carbon coordinator.

What happened
Arena says Gemini 4 Hydrogen is the fastest model in its Agent Arena top 10, with a typical step taking 7.3 seconds, about 2.7x faster than Claude Sonnet 5.5 and 3.1x faster than GPT-6.1 Sol. The model is now widely available on Google Cloud, per launch partner Parallel, and has landed in the Antigravity CLI,...
Why it matters
Developers building AI agents may weigh these reported speed gaps when choosing models for multi-step tasks. Teams on Google Cloud or using the Antigravity CLI can test the model directly. Watch for independent benchmarks, since the speed figures in the source come from Arena's post and its launch partner.
