Orchestrator

Google has launched Gemini 4 Hydrogen, targeting everyday coding and agentic workflows at $1.50 per million input tokens and $7.50 per million output tokens, covering the full 1M-token context with no tiered pricing. Versus Gemini 3.8 Flash it completes tasks 2.5x faster at the default high thinking level and lifts Terminal-Bench 4.1 from 18.2% to 57%, alongside an Orchestrator feature that dynamically switches between Carbon and Hydrogen within a session.
