AI code correctness predictors tested for robustness across languages and benchmarks

By PulseAugur Editorial · [2 sources] ·

A new research paper investigates the reliability of large language models in judging code correctness, particularly when faced with distribution shifts across different projects and programming languages. The study compares six execution-free predictors on models like Qwen3-Coder-30B and GPT OSS 20B, evaluating their ability to predict both the model's verdict and the program's actual correctness. Causal localization methods showed improved robustness to language shifts for verdict correctness, outperforming non-causal predictors, though this advantage was not consistent across all models or benchmark shifts.

    Which Signals of Code Correctness Survive Distribution Shift? Hidden-State and Causal Predictors of Program and Verdict Correctness

    Large language models increasingly judge code, yet without external feedback such judgments are unreliable, and verifying them by executing tests or by extended reasoning is costly. Instead, execution-free correctness predictors use signals from the model's output probabilities, …
