How Reasoning Models Are Trained

You can't teach deep reasoning by showing a model more examples of good reasoning — because the best reasoning for a hard problem often isn't in any dataset, and imitation caps a model at the quality of what it imitates. The breakthrough behind modern reasoning models was to stop imitating and start rewarding: let the model try to solve problems, check whether it got them right, and reinforce whatever thinking led to correct answers. That shift — from imitation to reinforcement on verifiable outcomes — is why reasoning models can think in ways no one wrote down.
