Google's Gemini 4 "Krypton" checkpoint leaks, topping Carbon in code gen and 3D scenes

APPSO · wechat · 2026-11-10

Early testers leaked screenshots of an internal Gemini 4 checkpoint codenamed Krypton in Google AI Studio, clearly beating the two-week-old Carbon in code generation, visuals and 3D scenes.- @Chetaslua generated a full animation with a single prompt in pure JavaScript, zero external assets: 39m16s at 105 tok/s. Under identical prompts Krypton took 2x Carbon/Argon's time and wrote 2x the code—"the hardest-working Google model I've tested." In a PS4-controller SVG test it used 386s and 930 lines for finer textures and port details, and was dubbed "king of audio," synthesizing music and sound effects note-by-note from oscillators. An interactive 3D sailing-ship demo showed surprisingly realistic water.- A leaked benchmark suggests the Flash-tier "Hydrogen" reaches GPT-6 Astra level. Some claim Google is at or nearing RSI; skeptics say "I'll get excited when there's a button." With Carbon arriving 15 days after Argon and Krypton leaking 12 days later, frontier releases now cycle weekly.
