What Opendatabay is
Opendatabay is a marketplace where individuals, researchers, and enterprises can buy and sell datasets for AI and large language model use. Its catalogue includes text, image, audio, video, code, agentic trajectories, 3D spatial, tabular, time-series, human feedback, and synthetic data. The platform describes its search and recommendations as AI-powered. It says listings are pre-curated and labelled for model training or fine-tuning, and that this can reduce preprocessing time by 20–40%. Buyers receive licensing terms and provenance information; the company says datasets undergo seller verification and due diligence. Both free and paid data products are offered. Sellers can list for free, but self-serve sales carry commissions ranging from 30% for sales of $1–$100 to 5% for sales of $250,001 and above. Registered users who complete onboarding can download evaluation samples, but using those samples for production, commercial use, training, or redistribution requires a separate licence or purchase agreement. Opendatabay is available through the web and API, and the company identifies itself as Opendatabay Ltd., based in Beccles, United Kingdom.
