Video gen looks nice, but editing it is hard, especially when physics is involved. Text2Sim turns a text prompt into a sim + render setup, giving you a physically grounded video you can actually edit, and unlimited data for training video models & VLMs. simulation-intelligence.gith…

Compositional 3D reconstruction now feeds physics sim, but mostly with rigid bodies. Real scenes are full of deformable and thin objects like cords & paper. CoDimRecon reconstructs them as sim-ready curves, surfaces & volumes from multi-view photos 👇 shuzhaoxie.github.io/CoDimRe…

Do coding agents understand the dynamics of the world well enough to reconstruct it from video? We introduce 4DCodeBench to evaluate this ability through 4D inverse graphics. 4DCodeBench.com/ <🧵>

Nunchux AI (nunchux.ai) comes out of stealth today. Ten years ago at Berkeley, we spent whole nights on a Titan X in Theano, trying to make iGAN, pix2pix, and CycleGAN real-time so creators could see the results the moment they asked for them. Image models now cost about 10,000x more to run. Video is another two orders of magnitude beyond that. The reason for speed has not changed. Every attempt is a question, and the answer changes the next question. Latency decides whether the result arrives while the idea is still yours. Cost decides how many questions you get to ask. Quality decides whether the answers were worth asking for. So we are building fast, cheap, and high-quality multimodal inference for every developer and enterprise, and we are building with researchers from MIT, CMU, and Berkeley, along with engineers who have shipped at AMD, NVIDIA, and Snowflake. We are now opening access through the waitlist. New accounts get $10 in credits.
Nunchux is live at nunchux.ai! We’re building the frontier of multimodal generative AI inference: fast, affordable, high-quality serving for image, video, and world models. Our Modelverse brings 30+ image, video, and avatar models behind one API. Use Nunchux-optimized models in Radical Speed and Radical Value tiers, alongside partner APIs. More models are on the way. We’re opening access through the waitlist now. New accounts get $10 in credits. Read our launch blog: nunchux.ai/blog/building-the…

1st summer @ Genesis AI ✅ Heading back to CMU after an amazing few months working on simulation, real-to-sim-to-real, policy evaluation, and more. I’ll miss the Bay Area and the Genesis team—but the work together continues from Pittsburgh. Lots more to build 🚀

Try out Sheng-Yu's latest work with pip install tpips. TPIPS is a text-prompted image perceptual similarity metric and a revisit of the classic LPIPS metric.
How similar are two images? Prior metrics (e.g., LPIPS, DreamSim) give just a single score. But actually, there are multiple *senses* of similarity (color, pose, etc.) We introduce TPIPS -- Text-Prompted Image Perceptual Similarity "pip install tpips" peterwang512.github.io/TPIPS 🧵

Untangling a self-intersecting Möbius strip. Our SIGGRAPH 2026 paper "Untangling Surfaces via Shape and Mesh Repulsion" removes all intersections while preserving mesh connectivity and staying close to the input shape. Joint work with @Appled0reM, @keenanisalive and @minchen_li_.

A packed final day at #SIGGRAPH2026: 5 papers I’m excited to share, spanning barrier-free IPC, adaptive GPU IPC, symbolic simulation, robot design, and surface untangling. Grateful to all the collaborators behind these works 👇

Two new ways to push deformable simulation: - scalable GPU multibody dynamics and - an effective B-spline formulation for cloth. Both at #SIGGRAPH 2026 this Wednesday. Come see the ideas and the results 👇

High-order FEM has long promised higher accuracy, but was still slow for graphics. We changed that! Our quadratic B-spline FEM is 2× faster than standard linear FEM, improving #simulation accuracy and wrinkling details. See our #SIGGRAPH2026 paper at simulation-intelligence.gith…!

Humanoid robots don't need to look human. Meet Eno, our first general-purpose robot. Not a machine pretending to be human, but intelligence given a body. At Genesis, we’re building a future where robots don’t feel cold or distant, but capable, calm, and ready to help. Available Q4 this year.

Using AI to migrate IPC friction from one codebase to another, spent several days (chatting only, without me touching the code), ended up with these failed and passed unit tests. Not bad, but not surprisingly great yet :)

How well can a model watch a short video of some physical dynamics and actually predict what happens next? Introducing MPMWorlds: a new dataset and benchmark to evaluate how well models can reconstruct and extrapolate physical dynamics from video. zzigak.github.io/mpmworlds/ 🧵👇 (1/n)
