What if the cheapest way to reduce AI costs isn't a cheaper model?
We keep talking about AI agent costs as: model price × tokens × requests
But agentic systems add another cost: uncontrolled execution.
An agent retries a tool 5 times.
Calls an expensive model when a cheaper one would work.
Loops through unnecessary steps. Hits APIs it didn't need.
Delegates work to another agent.
You don't just pay for intelligence.
You pay for every action an agent takes.
So we're wondering:
Could an Agent Control Plane become a cost-control layer too?
Agent Control Plane lets you set policies like:
“This agent can spend $X per day.”
“Don't use Opus for this class of request.”
“Stop after N tool calls.”
“Don't retry this API more than twice.”
“Ask for approval before crossing this threshold.”
Maybe the cheapest AI agent isn't the one with the cheapest model. Maybe it's the one you can actually control.
How are you controlling agent spend today?

@vijaypoudel1 Honestly, it’s the loop cost that really keeps me awake at night, not the input tokens. Just last month, we had an edge-case agent that got trapped in an infinite retry loop due to a 429 rate limit. I woke up to a staggering $1,400 bill for an agent that didn’t achieve anything at all. Budget caps have become essential; without circuit breakers at the gateway layer, you’re essentially operating in production without any safety nets.

@mateo_rossi exactly the problem that we are solving with Traccia.
You can enforce policies around the maximum number of retries, tool calls and many more. The agent run gets killed in real time on violation
@mateo_rossi @vijaypoudel1 Agreed, there are several that I use often depending on the project, caps on retries, spend caps, deadlines, etc.
I like the idea of keeping an eye on how agents use resources, not just which model they use. That can make a real difference in costs.

@oliver_graf1 great that it resonated with you

The case I'd test is two agents sharing one budget. Each can pass a 'remaining spend' check before either charge is recorded, then together exceed the cap. I'd reserve budget before dispatch and reconcile it after the call. Does Traccia's limit cover a shared budget across concurrent runs, or is it per run today? Disclosure: I build Pushary, on the approval side.
