ChatGPT 5.1 vs. Claude Opus 4.5 vs. DeepSeek-V3.2 (left) (middle) (right) prompt I used: Create a single HTML file containing a realistic cloth simulation using HTML5 Canvas and JavaScript. The cloth should be a grid of points connected by constraints using Verlet integration. Implement gravity and mouse interaction: the user should be able to click and drag particles to tear the cloth. The physics must remain stable without exploding.

There's a lot of speculation about whether OpenAI's video generation model Sora has a 'physics engine' (bolstered by OAI's own claims about 'world simulation'). Like the debate about world models in LLMs, this question is both genuinely interesting and somewhat ill-defined. 🧵1/

We gave Grok 4.5 and GPT-5.6 Sol the exact same prompt and compared the outputs side by side. The task: generate a fully interactive HTML5 glass bridge simulation with realistic physics, structural failure, cinematic visuals, polished UI, and smooth animations. The difference is actually visible.

With the recent three-mesh-bvh changes you can finally make a full scene-wide BVH to accelerate physics, raycasting, etc. And at some point Pathtracing 😁 Its just a prototype so far but it "just works" with objects and batched instances in a single structure. #threejs #gamedev

Robora Sim: A PyBullet-Powered Environment for Learning Robotic Physical Intelligence We are currently building our Robora simulation environment setup for our sim based learning, leveraging PyBullet, an industry-standard physics engine widely used in AI-driven robotics research and development. The environment is optimized with GPU-accelerated learning algorithms, enabling high-speed imitation learning and reinforcement learning within a safe and controlled virtual setup before shipping out to real world. This simulation platform allows our models to learn, adapt, and generalize across different robot morphologies, terrain types and task objectives - all before deployment to the real world. At it's core, the system combines a VLA-powered high-level planner with low-level motion control algorithms, working cohesively to produce emergent, physically intelligent behaviors. This synergy between simulation, learning, and real-world transfer marks a major step forward in our pursuit of adaptive and intelligent robotic systems. Through advanced domain randomization and synthetic data generation, the Robora Simulation Environment ensures that policies trained in simulation transfer effectively to real-world robots, minimizing the sim-to-real gap. Moreover, users will be able to test and integrate their own hardware kits within selected simulation environments in the Robora Dapp, ensuring seamless compatibility and safer real-world implementation.

Always wanted to try combining my paper with NCA, and turns out this approach is a perfect starting point It decouples grid with rules from rendering by using SIREN as a decoder, so I just replaced it with SAD Same rules, different way to render them in higher resolution

For years Yann LeCun has argued that generative video models can't truly learn physics. DeepMind's Physics-IQ benchmark proved him right, reporting "a striking lack of physical understanding in current generative video models". The best one scored just 29.5%. This CVPR 2026 paper finds the fix in LeCun's own playbook. "Inference-time Physics Alignment" doesn't retrain the generator. It steers a video model's denoising at inference using a reward from VJEPA-2, LeCun's Joint Embedding Predictive Architecture. - Won first place in the ICCV 2025 PhysicsIQ Challenge with a 62.64% score, beating the previous state of the art by 7.42%. - Repurpose VJEPA-2's "surprise" score as a reward, then search and rank multiple candidate denoising trajectories at test time. - Why it matters: It's a neat vindication of LeCun's thesis. The pixel-prediction generator alone doesn't get physics, but the JEPA world model approach he champions supplies the physics the video model lacks.

One warrior. One impossible battle. Only one survives. Created with Seadance 2.0 on Lart AI Here is the link to try: Prompt: A cinematic, hyper-realistic 12-second action sequence in a ruined modern city at sunset. A fearless female warrior in realistic tactical combat armor faces a towering 40-foot monster with rough stone-like skin and glowing eyes. The monster charges with immense weight, causing the ground to crack, dust to erupt, and nearby vehicles to shake realistically. The woman sprints, slides under a massive punch, and uses momentum to leap from a collapsed concrete slab, delivering a powerful strike with an energy-infused sword. The monster staggers backward with believable body mechanics, destroying a building facade as debris falls naturally under gravity. She performs one final spinning aerial attack, slicing through the monster's glowing core. The giant collapses with realistic physics, creating a massive dust cloud, flying rubble, shockwave, and ground vibration. The woman lands in a controlled three-point stance, breathing heavily as the dust settles and sunlight shines through the smoke. Ultra-photorealistic, Hollywood blockbuster quality, handheld cinematic camera, dynamic tracking shots, physically accurate motion, realistic muscle movement, cloth simulation, debris, lighting, shadows, HDR, volumetric smoke, motion blur, 4K, 60fps, dramatic sound design, seamless action, no cartoon style, no exaggerated superhero physics, every movement follows real-world momentum and gravity.

In a masterclass at Sequoia Capital AI Ascent, Jim Fan laid out the "Great Parallel": how robotics is speedrunning the LLM playbook. 🔹 VLA → WAM: Moving from language-heavy models to "World Action Models" that dream in physics. 🔹 Teleop → EgoScale: Replacing manual data with human egocentric video. 🔹 Simulation 2.0: Using neural simulators like DreamDojo to turn compute into environments. "Our generation was born too late to explore the earth and too early to explore the stars. But we are born just in time to solve robotics." He believes that robots will pass the Physical Turing Test in the coming 2–3 years.

If you are using an if statement inside a for loop, did you know there's a better way of doing this is Swift? I'm talking about the where clause. Using the where clause in a for loop can provide several benefits over using an if statement inside a for loop: Readability: It explicitly states the condition that must be met for an element to be processed, making the purpose of the loop clearer to anyone reading the code. Efficiency: When using a where clause, the filtering of elements is done at the level of the sequence, which can be more efficient than filtering within the loop with an if statement. Brevity: Using a where clause often results in more concise code, as it eliminates the need for an if statement and associated braces. This can make the code more manageable and easier to maintain.

🚨 SCIENTISTS MAY HAVE DISCOVERED AN ENTIRELY NEW TYPE OF MAGNET. It’s called an altermagnet. And it behaves in a way physicists thought shouldn’t be possible. Unlike normal magnets… the material has almost ZERO net magnetism yet it still behaves electronically like a ferromagnet. That means it may combine: • the stability of antiferromagnets • with the speed and functionality of ferromagnets Researchers just observed a giant magneto-optical Kerr effect inside hematite one of Earth’s most common iron minerals. Why this matters: This could open the door to: • ultra-fast memory • low-power computing • next-generation spintronics • advanced quantum materials • AI hardware beyond silicon The strangest part? The magnetism is hidden in the material’s symmetry itself. Not in obvious magnetic alignment. Physics may have just uncovered an entirely new way matter can store and process information. We are entering the era of programmable quantum materials. Follow for more future physics and technology breakthroughs.

Multi-robot learning is getting a serious boost! 📚 Researchers have extended Isaac Lab to train heterogeneous multi-agent robotic policies at scale. The new framework supports high-resolution physics, GPU-accelerated simulation, and both homogeneous and heterogeneous agents working together on coordination tasks. They benchmarked different approaches (MAPPO: Multi-Agent Proximal Policy Optimization and HAPPO: Heterogeneous Agent PPO) across six challenging scenarios and showed that large-scale multi-robot training is not only feasible, but efficient. It’s an important step for real-world robotic collaboration, where teams of robots need to coordinate, split tasks, adapt roles, and interact dynamically, not just operate as identical clones. The code is open-source, and it pushes Isaac Lab closer to what robotics actually needs: scalable, physics-driven environments where many different robots can learn to work together. Here's the project page: ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

New nature paper today : Sony's Ace robot beats 3 of 5 elite table tennis players. Loses to professionals. Human players win points with faster-than-average shots (p<0.001 between won vs returned). Ace wins with ordinary shots. Same speed and spin profile whether it wins or loses the rally (p=0.88). It's playing a completely different sport than the humans are. Trained entirely in simulation. Zero sim-to-real tricks beyond good physics modeling and asymmetric actor-critic (critic sees ground truth, actor sees noisy sensors). Best part — after watching a point, 1992 Olympian Kinjiro Nakamura said: "I didn't think it was possible. But the fact that it was possible... means that there is a possibility that a human could do it too." Code: Paper:
