Skild AI open-sources Steel physics solver with NVIDIA: 13× faster than PhysX, ~3× less GPU memory
deepakpathak · x · 2026-11-10
Skild AI, in partnership with NVIDIA, open-sourced Steel, a scalable physics solver for heterogeneous environments. It runs simulations up to 13× faster than PhysX while using 3× less GPU memory, unlocking scalable simulation for manipulation. The team argues coding agents can now generate environments at scale, making simulation the next bottleneck, and invites industry contributions to close the sim2real gap.
