Defines the motivation and gives a tag-based example, but does not specify reward computation, weighting, or optimization details.

Response-formatting reward

As explained in Reinforcement Learning from Human Feedback

A format reward is a reward signal assigned according to whether a model output follows a required structural presentation convention.

A response-formatting reward is a small reinforcement-learning signal that encourages a model to present reasoning and answers in a required structural form. It makes the reasoning process more predictable by rewarding conventions such as placing reasoning inside <redacted_thinking>...</redacted_thinking> before the final answer. section 7.3.3

Applied alongside outcome-oriented rewards, response-formatting rewards:

Guide the model toward predictable output boundaries without defining the substantive correctness of the answer. section 7.3.3
Serve as one of several auxiliary RLVR techniques, alongside language-consistency rewards, length penalties, and difficulty filtering. section 7.3.3
Appear in reasoning-model training practice, including systems associated with DeepSeek R1, OpenReasonerZero, Magistral, and Skywork OR-1. section 7.3.3
