A test of what it costs to write the knowledge, run on 30 July 2026. Can one AI write a first draft and another AI catch its mistakes? Six short pieces of knowledge were written, with two mistakes put in on purpose. A reviewer that had not seen the answers checked them. In a second run, separate AI agents drafted, challenged and fixed the pieces in turn. The reviewer caught both planted mistakes, and two more that no one had planted. In the second run, both mistakes were fixed and none got through. No right piece was challenged by mistake. Six pieces is a small sample, and the mistakes were easy ones. The time a person would spend was never measured, so the cost question is still open.
