Findings

• IC-395Most mainstream LLMs exhibit positive ADCE across five tasks, indicating reliance on deep structure for problem-solving, with ADCE strongly correlated with accuracy (r² > 0.7) [eval]
• IC-396Closed-source LLMs (GPT, Claude) rely more on deep structure than open-source LLMs (Llama, Mistral), and open-source models' surface sensitivity decreases with model scale [eval]
