| A natural way to evaluate code programs is to see if they pass unit tests, it is the idea behind the [pass@k](https://huggingface.co/metrics/code_eval) metric, a popular evaluation framework for code generation models, on [HumanEval](https://huggingface.co/datasets/openai_humaneval) dataset, which was introduced in [Codex paper](https://arxiv.org/pdf/2107.03374v2.pdf). The dataset includes 164 handwritten programming problems. In the pass@k metric, k code samples are generated per problem, and a problem is considered solved if any sample passes the unit tests and the total fraction of problems solved is reported. | |
| In most papers, 200 candidate program completions are sampled, and pass@1, pass@10, and pass@100 are computed using an unbiased sampling estimator. | |
| This plot shows the pass@100 by model size, for CodeParrot, InCoder, PolyCoder, CodeGen and Codex (not open-source): | |
