Your AI and this story
- GPT-6 Astra117 days after its cutoff
- Claude Opus 5.556 days after its cutoff
- Gemini 4 Hydrogen147 days after its cutoff
- Grok 4.786 days after its cutoff
None of these four assistants can know about it. The closest, Claude Opus 5.5, stops 56 days before it.
Key facts
- In-context learning from one video; tasks up to ~10 minutes and dozens of steps never seen in pretraining
- Success: 96% seen tasks, 66% unseen tasks vs 9% for language-prompting (~7x)
- One demo video ≈ 380 post-training episodes; 11 minutes from demo to autonomous execution (plant potting)
- Trained on teleop, human video, simulation and data-capture gloves; runs on arms, humanoids and quadrupeds
- NVIDIA (2026-09-10): Skild at $100M revenue run rate 10 months after first deployment; 60+ deployment partnerships
What happened
S1 treats a human demonstration video as the prompt, the way an LLM takes an example in context. Skild says it is the first robotics foundation model to show in-context learning on extremely long-horizon tasks unseen in pretraining. S1 is in use with commercial partners; there is no public API. Skild also acquired Fetch Robotics assets (Zebra’s robotics division, 2026-04-15; see Skild AI acquires Zebra Technologies’ robotics division (formerly Fetch Robotics) to put its robot brain in warehouses) to speed up deployment.
Why it matters
Along with Generalist GEN-1.5 six days earlier, S1 marks the arrival of prompt-by-demonstration in robotics, a possible “GPT-3 moment” where adding a skill no longer needs a new training run. Results are company-reported.
