Google launches Gemini 4 Hydrogen for coding and agentic workflows

Google positions Gemini 4 Hydrogen as a fast, lower-cost model across consumer, developer, and enterprise surfaces, with reported pricing of $1.50/$7.50 per million tokens and a one-million-token context. Documentation clarifies API access and its Managed Agents role; a Box evaluation reportedly beat Gemini 3.8 Flash by five points, but independent validation and adoption remain outstanding.
