How it did it (Claude Code, Fable 5.2, effort Extra): no AI video generator. It installed Blender, built the bathroom as a 3D scene, and ray-traced it on a 4-core machine with no GPU. 9 shots, 41 seconds, with captions and a soundtrack it generated but couldn't listen to. It dropped its first idea, a battery-swap charger, after finding one already on sale.

I gave Claude Fable 5.2 one prompt before I went to sleep last night. I woke up to an invention and a finished video. "Invent a new machine that is innovative, actually useful, and seems obvious in retrospect. Then create a short photorealistic video that explains this new machine. Work hard until you are finished." Ladies and gentlemen, please meet Sweep.
Introducing Claude Fable 5.2 and Claude Mythos 5.2, designed to tackle the most daunting technical challenges. They’re capable collaborators on ambitious projects in many fields, and show improvements in areas like coding, reasoning, and vision.

Yes!
Multiple studies estimate that repealing the tariffs in full would immediately save every American about $100 per month. It should be one of the first things the new Congress does.

Over the past few months, Anthropic scientists have engaged in deep research partnerships with six organizations developing new medicines. We've also begun drug discovery efforts of our own. In doing so, we’ve learned much more about how Claude can support the many stages of drug development. In this blog post, we share some early results from these efforts, and describe how this work fits in with our wider ambitions in the life sciences. anthropic.com/research/early…

It's shocking how bad Siri has been for so long.

I had never used @ExaAILabs until 30 minutes ago. I saw @jasonlk's post, created a free account in 30 seconds, and connected it to @Muse. In minutes it pulled state and federal DUI and crash fatality data and built charts. (I'm in the alcohol monitoring space.) 👉 California DUI arrests: 366,834 in 1990 → 124,141 in 2019. Down 66%. 👉 In 2024, 912 of California's 3,876 road deaths were in crashes where a driver was at .15 BAC or higher -- nearly 2x the legal limit. Pretty incredible to have vast source data paired with an AI agent.
Our agents use a LOT of Exa For us, it just covers all the gaps. The gaps all the APIs and enrichment services we use for our agents don't cover. It's relatively cheap, so we basically run it unmetered (like Jev now, too) Something cheap enough to run unmetered 24x7 = something really big Especially if your agents use it all day and night long. As our agents do.

We got the Bambu P2S for my son's 9th birthday this past June and it's been great so far. Somehow we printed a sweet collapsible sword. The mini castle is a small test print of our much bigger 'vibe-manufactured' castle; we used Opus 5.5 and only a prompt to create the printable file.

Medical, tax, and legal. If you are not using a frontier model as a partner in reviewing the work product, that's a huge mistake. Fable found a serious prescription error post-ER visit for me.

@bot send them to me too.

We are now entering into an era where any product can be created exactly to a consumer's preferences & needs. I vibe-fabricated a dog door with a wifi-controlled lock, perfectly to the specifications & design of my house. I know nothing about metal fabrication or electrical engineering. It's now getting manufactured and delivered in 2 weeks -- for almost the same cost if I bought a mass-produced item off-the-shelf.

Terrible
Two years ago today this man told us "I will cripple you" (referring to the entire U.S. economy) if we didn't give his east coast port union workers what they wanted (60%+ wage increases and a pledge of no automation of our ports). It worked btw, he got all his demands.
