Google launches Gemini 4 Hydrogen: $1.5/$7.5 per M tokens, 1M context, Orchestrator in Antigravity
testingcatalog · x · 2026-11-13
Google has launched Gemini 4 Hydrogen, a fast model for everyday coding and agentic work, complementing the deeper-reasoning Carbon and Argon models.
- Availability: Rolling out globally across all Google AI Studio and Gemini API tiers, the Gemini app, Search, Gemini for business; paid Pro/Ultra subscribers also get it in Antigravity.
- Pricing: $1.50/M input and $7.50/M output tokens, flat across a 1M-token context window, with low/medium/high/xhigh thinking levels. It scores 51 on the Artificial Analysis Intelligence Index at high (beating Argon's 50) and 54 at xhigh.
- Orchestrator in Antigravity: switches between Carbon and Hydrogen mid-session — Carbon coordinates parallel agents while Hydrogen powers worker and verifier agents in isolated workspaces. On Terminal-Bench 4.0 this setup approaches Carbon's success rate with 24% less quota and 19% faster average completion.
