RLVR (Reinforcement Learning with Verifiable Rewards)
Post-training where the reward is computed by a checker (unit tests pass, the numeric answer matches, the output parses) instead of a learned reward model. The dominant recipe for reasoning models because it scales without human labels. Only works where you can write the verifier.

Three acronyms show up in every reasoning-model paper. Here is what each one does, why GRPO replaced PPO for most teams, what a verifiable reward is and why it is the whole constraint, and short runnable code for each idea.
