[Claude Suspected to Have Stopped Displaying Complete Thought Traces, Explainability Questioned] Deep Tide TechFlow reports that on July 25, University of Pennsylvania professor Ethan Mollick discovered that Claude may have stopped displaying complete summary thought traces and released a comparison of before and after. Mollick believes this is a significant loss that could undermine the model's explainability. He pointed out that even summarized thought traces can help users diagnose errors in ways that would otherwise be impossible, and these traces themselves hold insightful value. As of now, Anthropic has not provided an official explanation for this change.
