Google's Gemini 4 Hydrogen outscores the bigger Argon four weeks after its launch
Google has introduced Gemini 4 Hydrogen, which replaces the Flash series. On the independent Artificial Analysis Intelligence Index, the model nearly matches the pricier Gemini 4 Argon. Hydrogen scores close to Claude Sonnet 5.5 at a lower price, but costs about 2.5 times more per task than GPT-6.1 Sol and still trails on agentic coding.
