Field notes on AI coding agents: what they cost, where they break, and what shipped. Figures without a traceable source were cut.
24 write-ups on running AI coding agents in production — token bills, tool switching costs, where the agents actually break, and what the numbers looked like afterwards.
On the figures. Every number here traces back to a named source or a run we did. Numbers we could not trace were cut before publishing, not rounded or guessed. Each piece says up front that it was drafted with AI assistance.
Corrections wanted. If a figure is stale, a tool changed its pricing, or you ran the same thing and got something else — open an issue. That is what this repo is for.
Follow along. Atom feed — new write-ups land there first.
