I asked @claudeai Opus 5.5 to build the iPhone Duo in three.js. Every feature is within 0.08 mm of Apple's own AR model. It folds, unlocks, and runs a working OS. Safari loads any real website. Then it shot the film
iPhone Duo Review: 10,000 Folds Later...

Very excited to try out Claude Duet! Made with @claudeai Opus 5.5
We’re opening a research preview of Claude Duet, a new app where Claude works as a proactive agent. It comes to you with what needs your attention, completes tasks you ask of it, keeps working when you step away, and checks with you before it acts on your behalf.

A visualization on how @OpenAI solved a Millennium Prize Problem
We’re sharing a solution to the Navier-Stokes Millennium Prize Problem, one of the deepest problems at the frontier of mathematics. The proof was produced by a group of agents, using an OpenAI next-generation model significantly more capable than GPT-6 Astra. The problem concerns whether the description of smooth three-dimensional fluid motion modeled by the Navier-Stokes equations can break down. It has remained unresolved for roughly 90 years.

This is how @AnthropicAI used Mythos 5 to improve quantum circuit efficiency Made with @claudeai Opus 5.5
New from our STEM Fellows Program: Designing more efficient quantum circuits with Claude. Given plain-language instructions, Claude Mythos 5 designed quantum circuits that improve on the best published ones, sometimes by an order of magnitude or more. More efficient circuits reduce the resources needed by quantum algorithms, which could bring quantum computing applications in chemistry and materials science within reach sooner.

A visualization on how @AnthropicAI's new Scion source control works Made with @claudeai Opus 5.5
New on our Engineering blog: Creating in-house source control. In May, we merged around 2,500 code changes per day. In September, we merged more than 30,000 per day. As a result, we became bottlenecked by developer infrastructure built for human (rather than agent) scale. Here, we share how we built a new version control system—and fully migrated our monorepo from git—in five months: anthropic.com/engineering/re…

Has @claudeai just achieved Recursive Self Improvement?
We keep improving performance across Claude, and you may have noticed it starts responding sooner! Claude Code now gzips the conversation it sends on every turn, so it reaches the model faster. Cloud sessions also start up as soon as you start typing.
