Google Releases Gemini 4 Hydrogen Agentic Model
Google released Gemini 4 Hydrogen, a fast agentic model that edges out Gemini 4 Argon on the Artificial Analysis Intelligence Index (51 vs. 50) at a lower price. Its key design is role-splitting: in Google Antigravity, an Orchestrator mode has Gemini 4 Carbon plan while Hydrogen edits files, updates packages and runs tests, handing control back on friction. It scores 57% on Terminal-Bench 4.1 and finishes tasks 2.5x faster, though at $1.50/$7.50 per 1M tokens it costs twice the 3.8 Flash intro rate.

▲ Google just released Gemini 4 Hydrogen, a fast agentic model that scores above Gemini 4 Argon at a lower price.
The key idea is role-splitting. In Google Antigravity, an Orchestrator mode lets Gemini 4 Carbon plan while Hydrogen edits files, updates packages and runs tests. When Hydrogen hits friction, it hands control back to Carbon.
Google reports 51 on the Artificial Analysis Intelligence Index at high (54 at xhigh), versus Argon's 50. On Terminal-Bench 4.1 it hits 57%, versus 18.2% for Gemini 3.8 Flash, and finishes tasks 2.5x faster. It is a trade-off though: at 7.50 per 1M tokens, it costs 2x 3.8 Flash's current 3.75 intro rate, and synchronous output caps at 65,536 tokens.
