Ask HN: For Enterprise coding agents, what's your company doing to control cost?

For those of you with enterprise pay-as-you-go plans, what's your company doing to keep costs from exploding? Do you have monthly limits? How do those limits spread across vendors? Does everyone have the same limit? What happens if you hit that limit halfway through the month?

My company is a medium size startup trying to support multiple vendors and harnesses. We're thinking of having tiers of limits (tech vs non tech) and allowing users to decide where they want to spend that.

Curious to hear what others are doing as prices and usage get higher and higher.
