Why Strong Models Still Fail

Same model, same prompt, wildly different results — the variable isn't intelligence.

Two teams gave the same model the same task and got opposite results. This course shows you why capable AI coding agents fail on real engineering work, and how to tell a harness problem apart from a model problem before you waste an afternoon fixing the wrong thing.
