Claude Code
RLVR (Reinforcement Learning with Verifiable Rewards)
A reinforcement learning method that rewards a model only when its output passes a programmatic check, such as a math answer matching the reference, code passing unit tests, or a response meeting a stated constraint.
In depth
A reinforcement learning method that rewards a model only when its output passes a programmatic check, such as a math answer matching the reference, code passing unit tests, or a response meeting a stated constraint. The reward comes from a verifier instead of a learned reward model, so no human preference data is needed and the signal is harder to game. AI2 named the method in its Tulu 3 paper. The same idea drove DeepSeek-R1, whose reasoning skills came from RL on verifiable math and coding tasks.
