• A physicist spent a year of his life and ~500 pages of hand calculations for quantum gravity in his PhD thesis, but Opus 5.5 did it in 10 hours, including the article and GitHub repo. And it even found the errors. What will "labor" mean in academia from now on? (r/singularity · 1005 pts · 260 comments)
  The post claims Opus 5.5 audited a physicist's roughly 500-page quantum gravity PhD thesis in 10 hours, producing an article and GitHub repo and finding errors. Commenters clarify the audit was by E. O. Kahya, the original author of 2007 papers with Woodard.
• Rumours are floating (r/singularity · 747 pts · 61 comments)

• Six frontier AIs competed to design and 3D-print egg-protecting capsules. Claude Opus 5.5's egg survived a 20-foot drop without a crack. GPT-6 Astra failed at 8 feet, while Gemini 4 Argon, Grok 4.7, Qwen 3.8-Max, and Muse Wonder failed at 4 feet. Claude dominates another real-world engineering chall (r/singularity · 612 pts · 62 comments)
  A post describes six frontier AIs designing and 3D-printing egg-protecting capsules: Claude Opus 5.5's egg survived a 20-foot drop, while GPT-6 Astra failed at 8 feet and Gemini 4 Argon, Grok 4.7, Qwen 3.8-Max, and Muse Wonder failed at 4 feet. Comments praise Claude's shock-absorbing design.
• Fields Medalist Richard Borcherds on OpenAI proofs: "I think what people are getting upset about is they’re slowly realizing that they are dumb and somehow blaming this on AI, even though it’s not really AI’s fault" (r/singularity · 611 pts · 208 comments)
  The post quotes Fields Medalist Richard Borcherds saying people upset about OpenAI proofs are slowly realizing they are dumb and blaming AI, though it is not really AI's fault. It links a Daily Cal article about UC Berkeley's math community after OpenAI's Navier-Stokes proof.
• Yann Lecun: Tesla "Flying" Roadster Is A Marketing Stunt (r/singularity · 588 pts · 344 comments)
  Yann LeCun calls Tesla's 'flying' Roadster a marketing stunt, saying compressed-air thrusters might give acceleration boosts or brief hover only if a 400-liter high-pressure tank replaces the passenger seat, but are not a path to flying cars. He says he owns two Teslas and is politically anti-Musk.
• MiniMax M3.1 Flash released, Model weights Oct 23 (r/LocalLLaMA · 528 pts · 123 comments)
  The post announces MiniMax M3.1 Flash and says model weights arrive October 23; the visible comments share benchmark images and ask about M3's size, noting the size affects how excited they should be.
• Kromoss is out. (r/StableDiffusion · 374 pts · 178 comments)
  The post announces that Kromoss is out, links to its Hugging Face page at lodestones/Kromoss, and asks when it was managed; the author calls it a huge improvement in quality.
