Qwen3-4B-Instruct-2507 hidden states reveal code correctness

By PulseAugur Editorial · [2 sources] ·

Researchers have investigated whether code correctness can be identified within the hidden states of the Qwen3-4B-Instruct-2507 large language model. Their study on the LiveCodeBench dataset revealed that code correctness is linearly decodable from the prompt-final hidden state with high accuracy, even after accounting for prompt length. Furthermore, the model's attempts to repair failed code snippets showed a detectable shift in hidden states, though this signal was found to be a correlate of the repair context rather than an isolated comprehension feature.
