Researchers have investigated how large language models can identify and correct their own mistakes without external input, drawing parallels to second-order confidence models in decision neuroscience. Their findings suggest that a specific internal signal, cached after the answer, plays a crucial role in error detection and self-correction, going beyond simple token log-probabilities. This signal not only indicates a likely error but also whether the model possesses the knowledge to fix it, as demonstrated through experiments with Gemma 3 27B and Qwen 2.5 7B models. AI
