Google's Gemini 4 Hydrogen outscores larger Argon four weeks after launch
Original title: Google's Gemini 4 Hydrogen outscores the bigger Argon just four weeks after its launch
The fast model costs $1.50 per million input tokens and is live in the Gemini app and API.
Google released Gemini 4 Hydrogen, a fast, lower-cost model for everyday tasks, separate from reasoning models Carbon and Argon. Google and Artificial Analysis say Hydrogen can outscore larger Argon on the Artificial Analysis Intelligence Index. It offers a one-million-token input and output window and is rolling out in the Gemini API, app, Search, and Antigravity. Google also says it is faster and less prone to hallucination than Gemini 3.8 Flash.
Unconfirmed: Speed, cost-performance, and benchmark claims come from Google or Artificial Analysis.
- Input costs $1.50 per million tokens and output $7.50; cache hits cost $0.075.
- Thinking levels are low, medium, high, and a new xhigh tier.
- Google says Terminal-Bench 4.1 rose from 18.2 percent to 57 percent versus Flash.
- Artificial Analysis says Hydrogen fabricates answers 8 percent of the time.
- An Antigravity orchestrator can switch between Carbon and Hydrogen in one session.

Google's Gemini 4 Hydrogen replaces the Flash series, but benchmarks suggest it also makes the pricier Argon obsolete. On the independent Artificial Analysis Intelligence Index, Hydrogen nearly matches Claude Sonnet 5. 5 for less money but costs about 2.
