😶‍🌫️ Interactive Apps @gcduncombe used Argon to build a live app where you can "fog up" your camera lens and draw on it. It tracks her mouth position and mic input… perfect for distracting yourself in your next video call. xitter.cf/gcduncombe/status/2110…

A math problem older than Google has been solved, with AI doing much of the searching. Microsoft researcher proved this 31-year-old Math conjecture (Kannan-Lovász-Simonovits conjecture) after AI agents explored over 100 approaches. A 140-page proof, more than 100 AI-explored paths now have closed a question mathematicians had been working on since 1995. A human-directed search, with AI agents exploring roughly 100 research trajectories while a researcher cut weak directions between rounds, produced the criterion underpinning Song and Zhang’s proof of the Kannan-Lovász-Simonovits (KLS) conjecture. The AI explored candidate approaches, carried out derivations, helped prepare the manuscript and ran internal proof checks, while the recursive method and the error bound that finished the proof are credited to the 2 researchers. About the Kannan-Lovász-Simonovits conjecture: Picture a random walker wandering inside a convex shape: the conjecture says no secret narrow passage can trap it, so it can explore the whole shape efficiently, even in huge dimensions.

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.

Now *thats* some big upgrade: Tibo says logged-in Codex and Work users now get *permanent prompt caching.* That’s a big upgrade for long coding sessions. You can leave a large project conversation, come back hours or days later, and reuse the cached context without losing the benefit simply because you took a break.

Gemini 4 Argon built a 3D periodic table synced to Tom Lehrer’s song, “The Elements.” Created in @Antigravity, it animates orbiting electrons, atomic data, and light spectra.
