Google's Fifth AI Release in Four Days: Gemini 4 Hydrogen Lands as Jensen Huang Exits Nvidia

Google shipped Gemini 4 Hydrogen on Wednesday — a Flash-tier replacement optimized for everyday coding and agent workflows, scoring 54 at its extended thinking level, with native routing from Carbon to Hydrogen in Antigravity multi-agent pipelines. It was Google's fifth distinct AI release in four days alongside Carbon, Gemini Robotics 2.5, AlphaGenome 2, and Gemini for Healthcare. Meanwhile: Jensen Huang resigned as Nvidia CEO effective immediately after a second affairs report, with CFO Colette Kress as interim CEO and $108B earnings on Tuesday. And nonprofits filed the first lawsuit naming all five frontier AI labs, seeking a court order to halt development.
