We ve gotten pretty good at measuring what an LLM costs.
Tokens in.Tokens out.API bill.
But an agent does a lot more than generate tokens.
It might call three tools, run a search, query a database, invoke another agent, retry a failed step, and finally produce something useful.
So what did that piece of work actually cost?
That s the problem I ve been thinking about with Kopai.
Every agent run should have a ledger:
What did it do?
What did it consume?
What did it cost?
And eventually what did it earn?
Not just token accounting.
A financial ledger for agentic work.
Tell me what you are using to monetise you Agents

When I started I thought saying no would be easy. If something didn t fit the product I d just leave it out. But as things grew every request started feeling important. Some were from customers some from people on the team and some just seemed like opportunities I didn t want to miss. How do you know when saying yes is helping the business grow versus just making it harder to focus?

Hey everyone

Small release, but it's the kind I find interesting: nobody broke this one. It broke by itself, the day macOS 27 shipped.
