I write the benchmarks and field notes on this blog. Spendassay audits AI spend for a living — idle seats, duplicate tools, metered pricing, and the gap between what an AI tool costs and what it actually ships — and this is where I write down what that work turns up.

The rule for everything here is the rule for the product: every number carries a proof level, and every figure that can be cited is cited to a primary source, with the date I read it. When the research makes our own case harder — as the METR and DX findings on AI coding ROI do — we lead with it anyway.

How we measure is public, layer by layer, in the methodology. For corrections or a source we got wrong, email hello@spendassay.com.
