First, there could have been industrial espionage involved so who knows. Ignoring that, you’re missing what I’m saying. Think of it this way - if it requires O1’s input to reach almost the same task performance, then this approach gives you a cheap way to replicate the performance of a leading edge model at a fraction of the cost. It does not give you a way to train something that beats a cutting edge model. Cutting edge models require a lot of R&D & capital expenditure - if they’re just going to be trivially copied after public availability, the response is going to be legislation to keep the incentive there to keep meaningful investments in that area. Otherwise you’re going to have another AI winter where progress shrivels because investment dollars dry up.

That’s why it’s so hard to understand the true cost of training Deepseek whereas it’s a little bit easier for cutting edge models (& even then still difficult).

When you build a new model, there is a spectrum of how you use the old model: 1. taking the weights, 2. training on the logits, 3. training on model output, 4. training from scratch. We don't know how much advantage #3 gives. It might be the case that with enough output from the old model, it is almost as useful as taking the weights.
