Google tests internal 'hydrogen' model, signaling push for faster AI options

Google is currently testing an internal AI model named Hydrogen, which engineers describe as being very capable, fast, and efficient. This new model is being accessed by staff through Google's internal development platform, Jetski, suggesting a potential future public release. Hydrogen is being compared by one employee to Google's earlier Flash models, which were designed as cost-effective workhorses. This development follows the recent launch of the Gemini 4 family, including Gemini 4 Carbon, which Google announced is strongest for cybersecurity and multi-step tasks, though both Carbon and Argon are currently restricted to paying subscribers. This internal testing comes amid heightened competition; Anthropic recently unveiled its Fable and Mythos lines, claiming superior abilities in finding cybersecurity flaws and designing physical hardware. The company has not commented on the Hydrogen model's potential pricing structure, though Google does offer other Flash models for free in its Gemini app.
