The passage around this formula
…APIs, and leave the backend database in a state matching an annotated goal — the authors found that even strong agents succeeded on well under half of tasks at pass@1, and that reliability across repeats fell sharply as k increased: an agent’s pass ^k score in the retail domain dropped below 25% by k=8 , and airline-domain performance, already lower at k=1 , degraded further from there [ 3 ] . Put in words rather than symbols: an agent that a casual observer would call “usually right” on any given try is, on the…
