New paper turns open-ended LLM tasks into rule-verifiable games for self-improvement

A new paper proposes RLSVR, a way to make open-ended LLM tasks self-verifiable by turning them into rule-checkable games.

The approach starts from the limits of RLVR: open-ended writing and summarization tasks often lack a clean verifier, and learned judges can be gamed.
Inspired by multi-agent debate, the method creates an information asymmetry so one player is genuinely worse.
Reward comes from correctly identifying the worse player, which removes the need for a judge or reward model.
The authors say it improves writing, summarization, and reasoning tasks.
