Cline ran Ox Alpha and Fable on an actual bug from the Cline repository. Both fixed it correctly, but Ox Alpha used far fewer thinking tokens, and Cline's write-up notes Fable announced it had found the root cause seven separate times before acting. The r/singularity thread (143 upvotes) reads this as a lab optimizing for reliability and token efficiency rather than raw capability, and the counter-argument in the comments is worth keeping: trusting a first conclusion can also mean missing edge cases, so fewer reasoning loops is not automatically better.
