Should models act as judges in reasoning contests?
JudgeLRM: Large Reasoning Models as a Judge
Published: 12 May 2026 · Updated: 13 July 2026
Read the original sourceWhat the paper says
JudgeLRM trains a model to evaluate the outputs of other reasoning models and assign scores. The authors propose using such a judge for automated evaluation and competition settings.
The Critique
Delegating judgment to a model introduces new biases and may incentivize optimizing for the judge’s quirks rather than for genuine quality. There is also a risk of reinforcing the judge’s biases over time.
Why It Matters
Automated evaluation could speed up benchmarking and reduce manual labour, but fairness must be maintained.
What They Missed
The paper does not explore calibration of the judge or how to prevent collusion among competing models.
The Big Question
Can we build unbiased, transparent evaluators for AI reasoning, or will we simply encode new preferences into our models?
