AI Usage

I write a lot about building software with AI agents. This page shows what that actually costs. Every agent reports its token usage, and the charts read straight from that data.

cc-sync, a Raycast extension I wrote, runs ccusage every 12 hours and remote-writes the result to my own Prometheus.

Everything spent so far, running. The dashed tail is a straight-line projection, not a forecast.

Dashed line projects 60 days at the last 30-day run rate of $120.54/day.

Model mix

share of daily spend

The daily spend chart normalised to 100%. This is where model migrations show up as bands taking over.

Cost per million tokens

weekly

What a million tokens cost me each week. When the dashed blended line falls while the model lines hold flat, the mix got cheaper rather than the models.

Input, output, and the two halves of prompt caching. Cache reads dominate, which is the whole reason the bill is survivable.

Every day this year, shaded by spend. Gaps are holidays, sick days, and weeks I was doing something other than shipping code.

These are list prices, not my bill. ccusage prices the tokens each agent consumed at published per-token rates. Wherever a flat-rate plan covered that work, the number I actually paid is lower. Read this as value consumed, not money out the door.

Today is missing on purpose: the extension only exports completed calendar days, so the newest day appears after the first sync past midnight UTC. Days with no bar are days I genuinely ran nothing.

Want the same page for yourself? The extension is on GitHub; point it at any Prometheus remote-write endpoint.
