RL engineers, you’ll want this one.

AI labs used to buy private training data for RL environments through brokers, NDAs and weeks of testing.

HUD just released DataVendor, an online marketplace where companies sell their private data to AI labs for training AI models.
Here a lab browses, checks automated quality results, tries a sample and buys at a listed price.

The marketplace won’t list or price public repositories, since frontier models have already trained on that code. Buyers see quality results and redacted file trees, and can run 1 random task from a taskset inside their own HUD workspace.

Another reminder that in the AI economy, proprietary data is one of the most valuable assets there is.
