What stands out
What its maker marketed at launch, and what people found later, each with its source.
In-context learning from one video, long-horizon
First
Learns tasks never seen in pretraining (potting a plant, cooking pancakes, pour-over coffee, kit assembly) from a single video prompt with no fine-tuning, for tasks up to ~10 minutes long; Skild calls this the first robotics foundation model to show in-context learning on such long unseen tasks.
Video prompting beats language prompting
66% success on unseen tasks vs 9% for an equivalently trained language-prompted policy (~7x); 96% on seen tasks; one demo video worth ~380 post-training episodes; 11 minutes from demonstration to autonomous execution in the plant-potting example.
Omni-bodied brain
Skild Brain is pitched as one model controlling quadrupeds, humanoids, arms and mobile manipulators without prior knowledge of the body; S1 trains on teleop, human video, simulation and data-capture gloves.
Notes
Announced on X 2026-08-25 (https://x.com/SkildAI/status/2092300842900865389); press 2026-08-31; NVIDIA blog 2026-09-10 (https://blogs.nvidia.com/blog/skild-ai-s1-physical-ai/) cites a $100M revenue run rate 10 months after first commercial deployment, 60+ deployment partnerships and Blackwell assembly work with Foxconn. Skild raised a $1.4B Series C at >$14B (2026-01-14, led by SoftBank). No public API, pricing or weights; company says S1 is “already at work with our commercial partners” and plans wider real-world rollout by 2027. Results are company-reported.
