# Google releases Gemini 4 Hydrogen, a lower-cost model said to outscore Argon > Source: > Published: 2026-11-12 22:50:02+00:00 ### Google releases Gemini 4 Hydrogen, a lower-cost model said to outscore Argon Google LLC today released Gemini 4 Hydrogen, a lower-cost model in its Gemini 4 artificial intelligence family said to outscore Google’s frontier [Gemini 4 Argon](https://siliconangle.com/2026/09/30/googles-new-frontier-ai-model-gemini-4-argon-goes-to-cybersecurity-defenders-first/) model on an independent intelligence ranking. Measured on the Artificial Analysis Intelligence Index at its default high thinking level, Hydrogen scored 51 to Argon’s 50, according to Google. A fourth thinking level called xhigh, new with Hydrogen, takes the score to 54. The rollout is different, too. Argon spent nearly two weeks with members of Google’s Fairwind Program, a group of vetted cybersecurity defenders, before paying developers [could get at it](https://siliconangle.com/2026/10/13/gemini-4-argon-reaches-gemini-app-pro-and-ultra-subscribers-alongside-a-new-tasks-mode/) on Oct. 13. Hydrogen skipped that stage. Anyone can use it from today, including people on the free version of the Gemini app. Koray Kavukcuoglu, who became head of Google DeepMind [in August](https://siliconangle.com/2026/08/05/google-reveals-big-shake-ai-teams-jeff-dean-leaves-demis-hassabis-moves-upstairs/) when Demis Hassabis moved into a chairman role, wrote in [the announcement](https://blog.google/innovation-and-ai/models-and-research/gemini-models/introducing-gemini-4-hydrogen/) that Hydrogen is “built for rapid execution.” Orchestrator, which Google added to its Antigravity coding tool today, picks between Hydrogen and [Gemini 4 Carbon](https://siliconangle.com/2026/10/28/google-debuts-flagship-gemini-4-carbon-model-with-cybersecurity-upgrades/) as a session goes along. Google’s runs of the Terminal-Bench 4.0 coding test found Orchestrator getting close to Carbon’s success rate on an average of 24% less quota. [Gemini 3.8 Flash](https://siliconangle.com/2026/09/02/google-launches-two-gemini-3-8-models-with-cutting-edge-reasoning-capabilities/), which came out in September, is the yardstick for most of the other numbers in the announcement. Against it, Hydrogen finished tasks 2.5 times faster at the default setting. On Terminal-Bench 4.1, which tests work done at a command line, Hydrogen more than tripled the older model’s 18.2% with a score of 57%. Among the early testers Google quoted, Andrew Carr, a former OpenAI scientist who is now chief scientist at 3D animation startup Cartwheel Inc., said the model caught two problems with an approach his team had been stuck on for 10 days. Discovery Loop Inc., the startup former Google Chief Scientist Jeff Dean co-founded after leaving in August, was another. Kavukcuoglu said in late September that Google wanted Gemini 4 out “[much earlier](https://thenextweb.com/news/gemini-4-release-kavukcuoglu-post-training)” than the end of the year. Three Gemini 4 models have now shipped in just over six weeks. Hydrogen arrived two days after Carbon, which also started out with Fairwind members, opened up to paying developers and Google AI Ultra subscribers. Hydrogen is available today in the Gemini API, Google AI Studio and Google Search, and paid Google AI Pro and Ultra subscribers can also use it in Antigravity. It costs $1.50 per million input tokens and $7.50 per million output tokens across the full 1 million-token context window. Argon costs $2 and $10 until its introductory pricing ends Nov. 30, then moves to $4 and $20. ##### Image: Google # A message from John Furrier, co-founder of SiliconANGLE: Support our mission to keep content open and free by engaging with theCUBE community. **Join theCUBE’s Alumni Trust Network**, where technology leaders connect, share intelligence and create opportunities. - **15M+ viewers of theCUBE videos** , powering conversations across AI, cloud, cybersecurity and more - **11.4k+ theCUBE alumni** — Connect with more than 11,400 tech and business leaders shaping the future through a unique trusted-based network ### Are you an AWS customer?  Support SiliconANGLE financially by buying your AWS services from our Marketplace portal page and links: [https://siliconangle.com/aws-marketplace/](https://siliconangle.com/aws-marketplace/) ##### **About SiliconANGLE Media** [SiliconANGLE](https://cts.businesswire.com/ct/CT?id=smartlink&url=https%3A%2F%2Fsiliconangle.com%2F&esheet=54119777&newsitemid=20240910506833&lan=en-US&anchor=SiliconANGLE&index=9&md5=646b1b564e2259100a2b8638aab0a552), [theCUBE Network](https://cts.businesswire.com/ct/CT?id=smartlink&url=https%3A%2F%2Fwww.thecube.net%2F&esheet=54119777&newsitemid=20240910506833&lan=en-US&anchor=theCUBE+Network&index=10&md5=7de2a85f95ab4a4a495cede20b8cb1da), [theCUBE Research](https://cts.businesswire.com/ct/CT?id=smartlink&url=https%3A%2F%2Fthecuberesearch.com%2F&esheet=54119777&newsitemid=20240910506833&lan=en-US&anchor=theCUBE+Research&index=11&md5=7bb33676722925eb57d588ec343e4f6f), [CUBE365](https://cts.businesswire.com/ct/CT?id=smartlink&url=https%3A%2F%2Fwww.cube365.net%2F&esheet=54119777&newsitemid=20240910506833&lan=en-US&anchor=CUBE365&index=12&md5=d310fb35919714e66ad8d42c9c0c1bc6), [theCUBE AI](https://cts.businesswire.com/ct/CT?id=smartlink&url=https%3A%2F%2Fwww.thecubeai.com%2F&esheet=54119777&newsitemid=20240910506833&lan=en-US&anchor=theCUBE+AI&index=13&md5=b8b98472f8071b23ebb10ab9a8dd0683)and theCUBE SuperStudios — with flagship locations in Silicon Valley and the New York Stock Exchange — SiliconANGLE Media operates at the intersection of media, technology and AI.
