If RLVR is strictly better for reasoning, why do produc...

RLVR is superior only within its specific domain. Once math and code competence are established, the model must handle open-ended tasks such as writing, instruction following, and multi-turn chat, where no verifier exists. RLHF with AI-judge feedback is the only practical signal source for these domains. The two stages address orthogonal capabilities and are used sequentially in all known production reasoning-model pipelines.
