Curating the best open reasoning datasets. A Bespoke Labs and DataComp community effort.

Our first goal is to curate a reasoning dataset to train state of the art small reasoning models that surpass DeepSeek-R1-Distill-32B and DeepSeek-R1-Distill-7B on math and code reasoning benchmarks.

We are a team of researchers and engineers from Bespoke Labs, Stanford, University of California Berkeley, University of Washington, Juelich Supercomputing Center (JSC), LAION, UCLA, UNC Chapel Hill, and Toyota Research Institute united around building the best datasets (and thus the best models). See our previous works at datacomp.ai and mlfoundations.
