Skild's S1 learns brand-new robot tasks from a single video — no retraining
Robotics has its "just prompt it" moment — or at least the strongest claim yet. Skild AI, the Pittsburgh startup behind the $14 billion-valued Skild Brain, says its flagship foundation model S1 can execute tasks it has never seen in training after watching one video of a human doing them — with no fine-tuning and no post-training. The company laid out the evidence in a technical blog post this week that is worth reading as a benchmark claim, not just a product pitch.
