New Technique Uses Weaker Models to Find Localized Reasoning Bugs in Stronger Ones
The method, called Woodpecker Distillation, argues many reasoning failures in large models come from specific, fixable bugs in intermediate steps rather than broad incompetence, and shows a smaller model can be used to locate them.
A paper posted to arXiv's artificial intelligence category this week, titled "Woodpecker Distillation," challenges a common assumption about why large language models fail on reasoning tasks they are otherwise capable of solving. The author…
