The best AI agents

The category that barely existed two years ago and now has the most money chasing it. The useful distinction is between an agent you supervise and one you don't, and between a product that runs agents and infrastructure that lets you build them. Read the pricing carefully; per-run billing behaves very differently from per-seat.
