Writing criteria

Lee Knowlton sorts work by whether an AI can verify it

Lee Knowlton posted a sorting rule: if an AI can independently tell whether its own output is good, build the verifier and scale it; if it cannot, you are the judge, so take one or two tasks at a time. For the middle case he says try an AI judge, but build evals to test the judge before trusting it.

sometimes a good judge is easy to build, sometimes it's so hard that you may as well not bother.
