What Frontier Labs Buy: A Data Deep Dive with Handshake AI's Garrett Lord and Team

Handshake's AI training business went from launch to $1 billion in gross annualized revenue in roughly a year, and this Latent Space deep dive with Garrett Lord and his team walks through the reinforcement learning environments frontier labs buy. In a finance demo, an agent working a simulated bank's email and deal files carries a goodwill figure into Python and subtracts it, a mistake that shows where expert judgment still beats the model. The team also presents VIALS, its benchmark for interpreting scientific images, and traces an agent's tool calls through safety simulations including CAREBench.
