Someone built Vork, a 3D and VFX engine where coding agents write the scene, render a frame, look at it, and revise. A new demo has Claude recreating an autumn-tree painting as a 3D simulation; the creator says it rendered in 37 minutes on one NVIDIA L4. Those figures weren't independently checked.

Grok’s leap isn’t just in coding—it’s showing up in 3D simulation, too 🏗️ Grok 4.7 (xhigh) scores 0.783 on BuildingBench, taking Grok from #9# to #3#! A big jump from 4.6’s 0.695. It now trails only GPT‑6 Astra (ultra, 0.843) and Fable 5.1 (max, 0.814). Median cost per building: $11.43, versus Astra’s $7.11 and Fable 5.1’s $33.15. Around 66% cheaper than Fable. Congrats @SpaceXAI and @ElonMusk! Coding agents are getting better at building the world.

Learjet N722BD's final flight, recreated using our models in a 3D simulation with its flight track and the real air traffic control audio. Miami Center warned the crew the turn to Freeport looked "pretty bad." Moderate to extreme precipitation, 25 miles out, a storm about 100 miles across. Controllers cleared them to deviate left or right. The pilot answered "Roger, we'll look at it" and stayed direct Freeport. Then she reported ice and moderate turbulence. Then the mayday. Descending 10,000 feet per minute. Overspeed. Descending 20,000 feet per minute. Banking 60 degrees. "We're going to crash into the ground." The controller's answer: "I'm here with you. Talk to me." The jet fell from about 37,300 feet to 325 feet over Greenacres, Florida in roughly 75 seconds...
