To be clear, we’ll want to see how this performs against the hold-out set. If it holds up, though, it’s a big deal, and kind of in line with the vibes this year, which I’d typify as ‘harness matters’. Maybe we’d upgrade to ‘harness matters immensely’ if this can 100% ARC-AGI-3 on existing models (more in the 13% range without this harness).

I’m pretty excited to see what sort of generalization we come to over the next 12 months on the harness side: if it turns out this can be RLed in as ‘consider if building a world model might help here’ and we get this as another native capacity, that will be interesting. If we get 100 of those problem-solving strategies all included, feels like we will see another hurdle cleared in terms of usefulness.

they could take open weight model, and check what will be impact from that harness on hold-out
