Bespoke Labs is an applied AI research lab building environment infrastructure, data curation, and evaluation tooling for AI agents and post-training. Its open-source Bespoke Curator library generates high-quality synthetic data at scale for model finetuning and structured extraction, and its Bespoke MiniCheck ("Argus") API offers a lightweight grounded-factuality / hallucination-detection service that scores whether a claim is supported by a given context. The lab is also known for OpenThoughts reasoning datasets, Terminal-Bench, the GEPA prompt optimizer, MiniChart, and OpenThinker. Backed by 8VC, Mayfield, and Wing Venture Capital.
