   Google Releases Gemini 4 Hydrogen: 2.5x Faster Than Gemini 3.8 Flash

   Google released Gemini 4 Hydrogen, a closed-weights model from Google DeepMind for coding and agentic work, with a 1,048,576-token unified window, four thinking levels (default high, plus a new xhigh), and API pricing of $1.50/$7.50 per 1M input/output tokens. Google reports it scores 51 on the Artificial Analysis Intelligence Index at high, 57% on Terminal-Bench 4.1 versus 18.2% for Gemini 3.8 Flash, and finishes tasks 2.5x faster than 3.8 Flash. It is available via the Gemini API, AI Studio, Android Studio and Google products, with Antigravity access requiring Google AI Pro or Ultra.

   Google launched Gemini 4 Hydrogen, the lowest-cost member of the Gemini 4 family, priced at $1.50/M input, $0.075/M cached input and $7.50/M output, compared with Carbon and Argon at $2.00/$0.10/$10.00 through Nov 30, 2026, doubling from Dec 1, 2026. The post notes Carbon and Argon share the same price, that Hydrogen is only a 25% discount until December 1st (then 75%), and that it remains far more expensive than Claude Haiku 5.5 and GPT-6 Luna at $0.10/$0.50. Hydrogen is described as the new free tier model and the model powering AI features in Google Search.

   Google’s new Gemini model is better at understanding complicated questions

   Google says its new Gemini 4 Hydrogen model can give more helpful answers to complex questions, including ones with multiple parts, hard-to-understand typos, or highly specific requests, by breaking them down and addressing each part. It is available starting today in Search, the Gemini app, all tiers of Google AI Studio, the Gemini API, Gemini for business, and Google Antigravity for AI Pro and Ultra subscribers, and is now the default model in AI Mode. Google says it delivers significant leaps in speed and intelligence compared to Gemini Flash 3.8 and matches or outperforms competing models like Claude Sonnet 5.5 and GPT-6.1 Terra.

   Google's Gemini 4 Hydrogen outscores the bigger Argon just four weeks after its launch

   Google released Gemini 4 Hydrogen, a fast general-purpose model for developers and everyday users that scores 51 on the Artificial Analysis Intelligence Index at its default "high" thinking level (54 at the new "xhigh" tier), beating the larger Gemini 4 Argon's 50. It has a one-million-token input and output window and costs $1.50 per million input tokens and $7.50 per million output tokens, with Google reporting a jump from 18.2% to 57% on Terminal-Bench 4.1 versus Gemini 3.8 Flash. Artificial Analysis found Hydrogen hallucinates only 8% of the time but lags on agentic terminal work, scoring 54% on Terminal-Bench 4.0 and 50% on Terminal-Bench-Science 0.1.

   Google rolls out Gemini 4 Hydrogen, finally replacing 3.8 Flash

   Google has released Gemini 4 Hydrogen, which replaces Gemini 3.8 Flash across its products with immediate access and more relaxed limits than earlier Argon and Carbon rollouts. Google says Hydrogen runs at four thinking levels (low, medium, high, and new xhigh), is 2.5 times faster than Flash 3.8 even in high mode, cuts "fabricated claims" by more than 5x, and more than triples 3.8 Flash's Terminal-Bench score. It scored 54 on the Artificial Analysis Intelligence Index in xhigh mode versus 50 for Argon.

   Introducing Gemini 4 Hydrogen

   Google announced Gemini 4 Hydrogen, a fast, efficient model for everyday coding and agentic workflows, available across the Gemini API, AI Studio, Gemini for business, the Gemini app, Google Search, and paid Google AI Pro and Ultra subscribers in Google Antigravity. It is priced at $1.50 per million input tokens and $7.50 per million output tokens across its 1 million-token context window, and surpasses Argon on the Artificial Analysis Intelligence Index at its default high thinking level (51 vs. 50, reaching 54 at xhigh). Google also introduced Orchestrator in Google Antigravity, which switches between models like Carbon and Hydrogen within a session and reached near-Carbon task success rates on Terminal-Bench 4.0 while consuming 24% less quota and completing 19% faster.
