Everyone is responding to the intellectual property issue, but isn't that the less interesting point? If Deepseek trained off OpenAI, then it wasn't trained from scratch for "pennies on the dollar" and isn't the Sputnik-like technical breakthrough that we've been hearing so much about. That's the news here. Or rather, the potential news, since we don't know if it's true yet.
That's not correct. First of all, training off of data generated by another AI is generally a bad idea because you'll end up with a strictly less accurate model (usually). But secondly, and more to your point, even if you were to use training data from another model, YOU STILL NEED TO DO ALL THE TRAINING. Using data from another model won't save you any training time.
That is not true at all.
We have known how to solve this for at least 2 years now.
All the latest state of the art models depend heavily on training on synthetic data.
