According to God of Prompt on Twitter, recent benchmarking reveals that chain-of-thought (CoT) reasoning in large language models experiences significant faithfulness degradation on difficult tasks, with Claude demonstrating a 44% drop and DeepSeek a 32% drop in faithfulness (source: https://twitter.com/godofprompt/status/2009224411379908727). This highlights a critical reliability issue for enterprise and research applications relying on CoT for complex decision-making, suggesting a business opportunity for AI developers to focus on advancing robust reasoning capabilities, especially for high-stakes or domain-specific deployments.
