Cosmopedia: how to create large-scale synthetic data for pre-training Large Language Models
Synthetic data just beat the scarcity problem. Here's how Hugging Face is pre-training LLMs without relying on real-world corpora.
Why it matters
Cosmopedia demonstrates a scalable approach to generating synthetic training data at massive scale, directly addressing the data bottleneck that limits LLM capability development. This shifts the model-building equation: compute and architecture matter less if you can manufacture unlimited high-quality training signal.
