Tests suggest cheap verifiers can work well in LLM post-training
A post quotes a paper reporting that, in Qwen3 tests on HealthBench and PRBench, higher agreement with frontier LLM reference judges did not consistently identify the best training verifier.
TLDR
The paper excerpt shared in the post says expensive verifiers need not outperform inexpensive ones across the tested domains. It reports strong training outcomes from open-weight Gemma verifiers, even though higher agreement with frontier LLM reference judges did not consistently identify the best training verifier.
