World models
Models that predict future states and enable real-time planning and decision-making for robot control. Every Robotics Weekly story on World models, newest first. 6 stories since September 2026.
- RPG robot watches one demo, practices in sim, goes 30 for 30
A real-to-sim-to-real pipeline that rebuilds the task in simulation, practices it, and updates a shared skill set from its own failures.
- FLUX 3 Action takes first place on RoboLab at 7B
Black Forest Labs put numbers on its open weights world action model, and Animesh Garg pulled out the ones that matter.
- Flex-pi world action model predicts 3D, not just video
A 6 billion parameter model adds geometry and object semantics to video prediction, and the authors say it needs far fewer demos.
Sound like you were at the demo
One email a day. Under three minutes. The demos, the deployments and the part the press release left out.
- Grounded Action Model beats pi-0.5 when the target changes
A robot policy built on a frozen 3D grounding backbone posts 61% average success on LIBERO-PRO, and the authors still call grounding errors an open problem.
- Lerrel Pinto sees "deep despair" as Astra zero-shots benchmarks
Chris Paxton started it, then walked part of it back within minutes.
- Unitree says its humanoids now fight fully autonomously
The claim is Unitree's own, and nobody in the sources has checked it yet.
