Gemini Krypton: Text Arena Rank Debut?

On November 9, 2026, OfficeChai reported that Google was internally testing a Gemini 4 checkpoint codenamed "Krypton," described by testers as an upgrade on Gemini 4 Carbon (https://officechai.com/ai/gemini-4-krypton/). This market will resolve to "Yes" if the Google "Krypton" model added to the Arena.AI Leaderboard (https://arena.ai/leaderboard/text/overall-no-style-control) holds a rank within the specified top ranks when the table under the "Leaderboard" tab is checked at 12:00 PM ET on the calendar date following the date on which it first appears on the leaderboard. Otherwise, this market will resolve to "No". A qualifying model must be a Google AI model named "Krypton" (including variants or successor branding such as Gemini Krypton, Gemini 4 Krypton, 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 model (e.g., Gemini 4.1) or an update to Gemini 4 Carbon, will qualify only if it is confirmed by June 30, 2027, 11:59 PM ET to be the same model previously codenamed "Krypton". Models merely derived from, distilled from, or incorporating improvements from Krypton will not qualify unless confirmed to be the same model.
