Moving Atoms (YC S26) — World models for training and evaluating robots

Our first model, Atom 1, pre-trained on the internets video, and fine tuned for physics, already tops the Physics IQ benchmark. It has been action conditioned, so you can simulate robot actions within it.

In their words

Our first model, Atom 1, pre-trained on the internets video, and fine tuned for physics, already tops the Physics IQ benchmark. It has been action conditioned, so you can simulate robot actions within it. This lets Robot Labs train their robots using GPUs instead of relying on human collected manual data that is slow and expensive. In unseen and hard to replicate environments, this is the only path to getting ANY training data.

If you're behind Moving Atoms: acceptance into a YC batch is one of the few weeks a young company gets looked up by people who matter — investors, other founders, press. FoxPlug turns the commits, deploys, and releases you're already making into that story automatically, so anyone who looks finds something current. GetFoxChat puts a guide on your own site so the people YC's own page just sent you don't read one line and leave.
