New Papers Push Back on Paying Frontier Prices to Grade Model Output
One study asks whether cheap open-weight models can judge natural-language mathematical proofs reliably, as forecasters put the model evaluation tools market near $1.15 billion in 2025.
Grading is now a recurring cost in evaluating reasoning systems, and frontier judges are expensive. A paper posted to arXiv on August 4 asks the direct question: can cheap open-weight models serve as reliable judges of natural-language math…
