The PolyCoder paper gives a nice comparison of existing code models. The authors also trained a code generation model 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
