The article discusses the challenge of controlling for accidental leakage in evaluating the coding abilities of models through an industry standard open-source evaluation benchmark called HumanEval. The authors found that even with conservative filtering heuristics, it was difficult to prevent data contamination from webpages and open-source code repositories. They discovered that continued pretraining on a dataset that included even a single epoch of the test split for HumanEval significantly boosted scores. The increase in scores persisted even when examples were embedded in extraneous formats like JSON or HTML. To minimize the risk of leakage, the authors recommend maintaining a small set of truly held-out test functions written in-house. They also introduced the Natural2Code benchmark as an alternative to HumanEval, which follows the same format but with different prompts and tests.
