For two years, AI got better and cheaper at the same time. Buy the latest model, pay less per token, win. That run is over.
Models still improve. But the bills climb with them, and almost nobody can tell you whether the extra spend is actually buying anything. The free-lunch era is over, and most teams are flying blind into the expensive one.
So I built something. Today I'm opening the private waitlist for Yolk: a free tool that shows you exactly what your AI spend is doing.
Why Build Yolk?
Every team I talk to is spending more on AI each month, across more providers, more tools, and more people. The only signal most of them get is the invoice. It tells you the number. It tells you nothing about whether the number is worth it.
The question that matters was never 'how much are we spending on AI?'. It is 'is any of this moving the needle?'. Right now that's almost impossible to answer, because the spend is scattered across a dozen accounts and nobody owns the full picture.
It's about to get harder, not easier. Frontier models are getting pricier and less predictable. The Claude Fable 5 ban showed how fast access can vanish, and the smart response is to spread across providers rather than bet everything on one. That's the right call, but it scatters your spend even further. You need one place to see all of it.
What Yolk Does
Yolk monitors your organisation's AI usage in one view. Model by model, provider by provider, member by member, task by task, and source by source. Instead of a stack of disconnected invoices, you get a clear read on where the money goes and what it produces.
No more guessing which team, which tool, or which workflow is quietly burning your budget. No more finding out at the end of the month. Just the picture, as it happens.
It's Free, and It Stays Free
Yolk is free. It will stay free. I'm not interested in charging you to look at your own spending.
It launches on web and Mac first, with a CLI for everyone else coming. The private waitlist is open now, and early access goes out from there.
Join the Waitlist
If you're spending real money on AI and want to know what it's actually buying, join the Yolk waitlist. Takes a few seconds.
And if you want a hand making sense of your AI spend, or building AI systems that are actually worth the bill, that's what we do at Valentis. Come and talk to us.
The free-lunch era is over. You may as well see the bill clearly.
