Gemini Hydrogen: HLE-Diamond Debut?

On November 5, 2026, OfficeChai reported that Google was internally testing a Gemini 4 Flash-tier model codenamed "Hydrogen," described as a lighter, faster sibling to Gemini 4 Argon and Gemini 4 Carbon (https://officechai.com/ai/gemini-4-hydrogen/). This market will resolve to "Yes" if the Google "Hydrogen" model added to the Humanity's Last Exam results at https://agi.safe.ai/ has an HLE-Diamond Accuracy of at least the specified percentage at 12:00 PM ET on the calendar date following the date on which it first appears on the site. Otherwise, this market will resolve to "No". A qualifying model must be a Google AI model named "Hydrogen" (including variants or successor branding such as Gemini Hydrogen, Gemini 4 Hydrogen, or similar naming) or be confirmed to be the same model referenced in the report by Google or by a consensus of credible reporting. A model listed under any other name, including a new Gemini Flash model (e.g., Gemini 4 Flash) or an update to an existing Gemini model, will qualify only if it is confirmed by June 30, 2027, 11:59 PM ET to be the same model previously codenamed "Hydrogen". Models merely derived from, distilled from, or incorporating improvements from Hydrogen will not qualify unless confirmed to be the same model. The percentage displayed as "HLE-Diamond Accuracy" for the model in its result card on the "AI Progress on HLE-Diamond" chart at https://agi.safe.ai/ will be used to resolve this market. This market will resolve solely based on t
