Reinforcement learning from verifiable rewards
Also called RLVR
What does “Reinforcement learning from verifiable rewards” mean?
Reinforcement learning from verifiable rewards: Scores a model's outputs with an automatic check instead of a learned preference model. The check might be whether a math answer is correct or whether code passes its tests. It has become a common way to train reasoning models on tasks with clear right answers.

What is an example of “Reinforcement learning from verifiable rewards”?
A unit test either passes or fails, so coding tasks give a clear reward signal that is harder for the model to game than a vague quality rating.
