Show it a single human demonstration of a long-horizon task and the robot performs it right away. No fine-tuning, no retraining.
Skild has released S1, a robot foundation model where you specify the task with a video demonstration instead of a language instruction.
Why video, not language
Language works for "hand me the mug." It falls apart for anything delicate or long-horizon. You don't learn to fold a fitted sheet from a sentence. So S1 takes a video demo into its context window and translates it to its own body and scene.
What it does
- Tasks up to 10 minutes, dozens of sequential steps
- Unseen tasks: potting plants, pour-over coffee, kit assembly, pancakes. Skild says even the underlying primitives, like flipping a pancake, weren't in pre-training
- Recovers from its own mistakes without being trained to
- Improves on flawed demos. Demonstrator drops an egg, S1 doesn't make that mistake. It reads the demo as a goal, not a trajectory to copy.
