Agent Data Curation
Data curation and evolutionary optimization for AI agents.
Data curation and RL environment recipes from ex-Google DeepMind researchers
Bespoke Labs builds tools and curated datasets for post-training, including the Curator open-source library and RL environment work for coding and enterprise tasks. Co-founded by Mahesh Sathiamoorthy (ex-Google DeepMind) and Alex Dimakis, it co-created the OpenThoughts reasoning datasets.
