Claude Opus 5.5 feels like the first model to have truly solved video animation. We one-shotted this promo video for @dubdotco using Opus 5.5 High via @cursor_ai and it worked remarkably well 🤯 h/t @pedrooladeira for the 🔥 vid

Claude just computed a nine-loop scattering amplitude in planar N=4 super-Yang-Mills, past the eight-loop record. What that means. Scattering amplitudes predict how particles behave & physicists compute them in layers of correction called loops. Each loop makes the answer more precise & costs exponentially, sometimes factorially, it’s more work. Most real amplitudes have only been taken to two or three loops. The most precise prediction in particle physics, the electron's anomalous magnetic moment, used five. The challenge came from physicist Matt von Hippel, who publicly asked whether an AI could push past eight loops using only compute an academic could afford. Given one prompt & periodic instructions to continue, Claude ran largely unsupervised for days & did it, using bootstrap methods that Lance Dixon & collaborators developed. Total cost: a few thousand dollars. Dixon, who held the prior record, checked the result independently. Three caveats that matter more than the headline: 1. N=4 super-Yang-Mills is a toy model which is a testing ground for techniques, not a theory describing our universe. No new real-world particle prediction came out of this. 2. Claude applied existing human methods rather than inventing new ones. 3. A human-led group at the Chinese Academy of Sciences, using GPT-6 for parts of it, had concurrently obtained most of the same result & published a dataset on September 17. So the honest version isn't that a machine beats humans. It's that a hard calculation at the edge of a field now costs only a few thousand dollars & takes several days, by more than one route at once.

Claude Opus 5.5 is the greatest AI model ever released It is the most intelligent model I've ever used, while be lightning fast and incredibly efficient The perfect trifecta In this video I cover why this should be your new daily driver and how to get the most out of it:

CLAUDE AUTONOMOUSLY DISCOVERED A NEW BIOLOGICAL SYSTEM Anthropic says Claude identified a previously uncharacterized enzyme system in bacteriophage DNA with CRISPR-like repeat arrays, which it calls ART. Around 950 Claude agents spent 21 hours and 210M tokens analyzing 200,000+ reverse transcriptases, finding 3,500 candidate systems and narrowing them to 20 before flagging ART for human review. Anthropic scientists then validated the system in its new molecular biology lab. Its function is still unknown, but Anthropic says the few known systems with similar features are programmable and can perform operations like cutting, copying and pasting DNA. The company says this is the first result from its new life sciences lab, where Claude generates biological hypotheses and human scientists test the most promising ones experimentally.

Claude Opus 5.5 is a very, very good model. Practically everyone at OpenAI was caught off-guard by this launch (not the timing, but the performance of the model!), and there's now a pretty "all hands on deck" atmosphere for 6.1 Astra - timelines are being compressed. But it'll face Fable 5.5! The RL magic really needs to do its work here
