Gemini 4 Hydrogen nears frontier models in independent tests
Google DeepMind released Gemini 4 Hydrogen with a new xhigh reasoning level, according to Artificial Analysis. The model scored 54 on the Artificial Analysis Intelligence Index, one point below Claude Sonnet 5.5 and GPT-6.1 Sol at maximum reasoning, while the high setting matched Gemini 4 Argon at about 19% of its cost per task; Artificial Analysis also reported strengths in visual reasoning and low hallucination rates, but weaker agentic terminal-work scores. The model supports a 1M-token context window and text, image, video, and speech inputs, with pricing set at $1.50 per million input tokens and $7.50 per million output tokens.
Artificial Analysis measured Gemini 4 Hydrogen near the intelligence scores of leading models while reporting lower cost than Claude Sonnet 5.5 and higher cost than GPT-6.1 Sol, making its price-performance tradeoff notable.
Google's new Gemini 4 Hydrogen has Intelligence just below Claude Sonnet 5.5 and GPT-6.1 Sol, at a third of Sonnet’s cost but ~2.5x that of GPT-6.1 Sol
@GoogleDeepMind has released their third new model in six weeks. Gemini 4 Hydrogen introduces an xhigh reasoning level and scores 54 on the Artificial Analysis Intelligence Index, with strengths in visual reasoning and non-hallucination. This places it 1 point behind Claude Sonnet 5.5 (max) and GPT-6.1 Sol (max), at ~32% of Sonnet’s cost but ~2.5x that of GPT-6.1 Sol. With high reasoning, Gemini 4 Hydrogen matches the Intelligence of Gemini 4 Argon for ~19% of the Cost per Task
Key takeaways:
➤ The new xhigh reasoning level scores 54 on the Intelligence Index: xhigh is the first reasoning level above high on a Gemini model, and puts Hydrogen 1 point below Claude Sonnet 5.5 (max) and GPT-6.1 Sol (max), and 4 points ahead of Gemini 4 Argon (high). With default (high) reasoning, Gemini 4 Hydrogen scores 51, just behind GPT-6.1 Sol (xhigh, 52) and Claude Opus 5.5 (high, 52)
