AI development at Google is gaining momentum. As Business Insider reports, citing internal correspondence, following the release of the Gemini 4 Argon and Carbon models, Google began internal testing of a new model, codenamed Hydrogen, focused on speed and efficiency.

In an internal email this week, one Google engineer described the Hydrogen as a “very capable, fast and efficient” model. The company’s employees accessed Hydrogen through Google’s internal development platform called Jetski. As a rule, the appearance of new tools on it precedes their public release.
One of the employees, who has already tested Hydrogen, compared the new product with previous Google Flash series models, which are considered “workhorses”: they work faster and are cheaper than, for example, the Argon model. The name Hydrogen, named after the lightest element on the periodic table, suits it perfectly.
With Google delaying and then canceling the release of Gemini 3.5 Pro earlier this year, many felt that the company was no longer keeping up with its competitors in the race to create frontier models of artificial intelligence.
But Google has put the doubts to rest and reasserted itself with the Gemini 4 family. On Tuesday, the company announced its latest cutting-edge model, the Gemini 4 Carbon, which it says is best suited for cybersecurity challenges and multi-step processes that require long-term planning. Currently, the Carbon and Argon models are subscription-only.
It is still unknown what access to Hydrogen will be in the event of its official release – paid or free. Other Google Flash series models are available for free to Gemini app users.
