AI costs

What do AI models and agents cost, and how do you cut it?

What AI agents and the tools around them really cost: plan limits, prices per task, enterprise agent pricing, and the levers that cut the bill, from routing and caching to cheaper models.

The most intelligence for the money, right now

Every model below is one no other model beats on both counts: none scores higher for less. The blended price is a million tokens at three input to one output, the usual mix of a chat or an agent; cached input is what a repeated prompt prefix costs instead. Every figure is read from OpenRouter's model feed every 6 hours, so the table changes when a lab reprices.
