A Polish company from Wrocław just signed a lunar mineralogy contract with @Int_Machines Intuitive Machines.

Engineering failures teach. Scale is built company by company. The optical instruments do the real work.

What if robots could imagine the future before acting?

Researchers from Fudan, NUS, and Shanghai Innovation Institute unveil World Action Models (WAMs).

They merge predictive world models with action generation, so robots plan by simulating how the environment evolves, not just reacting.

Outperforms standard VLA models in physical reasoning and action plausibility across simulations and real-world tasks.

AI is unlocking breakthroughs in quantum computing.

🤝 We collaborated with the University of Innsbruck to tackle a core challenge in building useful quantum supercomputers: automatically designing efficient quantum circuits.

Using NVIDIA CUDA-Q, we built a multimodal diffusion model to synthesize quantum circuits from scratch, optimizing circuit structure and gate parameters simultaneously to produce shorter, lower-error circuits.

💡 The standout result: the AI model independently rediscovered the Quantum Fourier Transform — without being told what the solution should look like.

Introducing WALL-WM, our open-source World Model for embodied AI and the next piece of our open-source robotics stack.

Carving World Action Modeling at the Event Joints
Read the blog: https://t.co/50XVN1ZjaA

Why it matters

WALL-WM shifts robot world modeling from fixed-length action chunks to event-grounded video-action pretraining. It learns around events like reaching, contact, grasping, lifting, moving, and placing, so language, vision, and action align more naturally.

Why you should care
WALL-WM brings together:
•Event-grounded VLA pretraining
•Prior-aligned video-action architecture
•Wan-based video tower + randomly initialized action DiT
•Multi-view perception with sight-cone masking, tube patch masking, and Camera RoPE
•Event Mode for variable-length execution
•Unified Mode with Staircase Decoding
•DMuon for large-scale training

The goal: help robots learn what physically matters, not just what happens in the next fixed slice of time.

SpaceX filed 685 pages with the SEC. $18.7B revenue. $41.3B accumulated deficit. $1.75T valuation.

Both are the same industry. Different scales. Different timelines.
