Description

Here you can find the code used for creating Cosmopedia, a dataset of synthetic textbooks, blogposts, stories, posts and WikiHow articles generated by Mixtral-8x7B-Instruct-v0.1. It contains over 30 million files and 25 billion tokens, making it the largest open synthetic dataset to date.

Cosmopedia covers a variety of topics; we tried to map world knowledge present in Web datasets like RefinedWeb and RedPajama, and generate synthetic content that covers them. This is the v0.1 of Cosmopedia, with ample room for improvement and topics to be more comprehensively covered. We hope this dataset will help the community's research efforts in the increasingly intriguing domain of synthetic data.

Code structure

• prompts: the code for building the prompts in each seed_data in Cosmopedia. In web_samples, you can also find pointers for the topic clustering we did.
• generation: the code to run large scale synthetic generations with llm-swarm using the prompts you built. Cosmopedia consists of 25B tokens and was generated in > 10k H100 GPU hours.
• deduplication: the script we used to run MinHash deduplication with datatrove.
• decontamination: the code we used to run n-gram decontamination against evaluation benchmarks, when training models on the dataset like cosmopedian-1b.
