Verifiable Reward
A reward you can compute mechanically: tests pass, the answer matches, the schema validates. The precondition for RLVR and the cheapest kind of eval you can build.

Where reasoning models come from, what they cost, and when to pay for them. The SFT to DPO to GRPO pipeline, reinforcement learning with verifiable rewards, test-time compute as a dial, and a method for deciding which of your requests deserve a thinking model.

GRPO, DPO, and RLVR: Post-Training Explained Without the Notation
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.
