| [PolyCoder paper](https://arxiv.org/pdf/2202.13169v3.pdf) gives a nice comparison of existing code models. The model was trained on **254GB** of data, after preprocessing, consisting of popular repositories for 12 popular programming languages with at least 50 stars from GitHub in October 2021. The data used the following preprocessing: | |
| - Exact match deduplication | |
| - Filtering: | |
| - Average line length < 100 tokens | |
| - Maximum line length < 1000 MB |
