# Code Hallucination Detection on BigCode Source: [Code Hallucination Detection on BigCode]() Collection index: [llms.txt]() Data updated: 2026-04-10T08:00:08.825Z Evaluation of model performance on detecting code hallucinations using the BigCode dataset, measured by OP, OR, and IF R. A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Code Hallucination Detection | | Dataset (including any stated split) | BigCode | | Metric | OP | | Unit | SCALAR | | Direction | Higher is better | | Results loaded | 16 of 16 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [OP](): Higher is better; unit: SCALAR. - [OR](): Higher is better; unit: SCALAR. - [IF R](): Higher is better; unit: SCALAR. ## Recorded results | Method | OP | Result date | Report paper | | --- | --- | --- | --- | | o3-mini | 0.77 | Not recorded | 69d883f27d0172140ec778fd | | o3-mini | 0.64 | Not recorded | 69d883f27d0172140ec778fd | | Pyright | 0.62 | Not recorded | 69d883f27d0172140ec778fd | | o3-mini | 0.57 | Not recorded | 69d883f27d0172140ec778fd | | o3-mini | 0.56 | Not recorded | 69d883f27d0172140ec778fd | | Mypy | 0.47 | Not recorded | 69d883f27d0172140ec778fd | | Grammar | 0.45 | Not recorded | 69d883f27d0172140ec778fd | | Pyright | 0.34 | Not recorded | 69d883f27d0172140ec778fd | | Pyright | 0.32 | Not recorded | 69d883f27d0172140ec778fd | | Pyright | 0.28 | Not recorded | 69d883f27d0172140ec778fd | | Mypy | 0.24 | Not recorded | 69d883f27d0172140ec778fd | | Grammar | 0.24 | Not recorded | 69d883f27d0172140ec778fd | | Grammar | 0.23 | Not recorded | 69d883f27d0172140ec778fd | | Mypy | 0.22 | Not recorded | 69d883f27d0172140ec778fd | | Grammar | 0.19 | Not recorded | 69d883f27d0172140ec778fd | | Mypy | 0.16 | Not recorded | 69d883f27d0172140ec778fd | ### o3-mini OP: 0.77.
