This code-related data from [Fineweb](https://huggingface.co/spaces/HuggingFaceFW/blogpost-fineweb-v1) was specifically used in [OpenCoder](https://huggingface.co/papers/2411.04905) pre-training. 
We employ fastText in three iterative rounds to recall a final dataset of 55B code and math-related data. 
You can find math-related data at [OpenCoder-LLM/fineweb-math-corpus](https://huggingface.co/datasets/OpenCoder-LLM/fineweb-math-corpus).
