Fable 5.1 is worth evaluating when a difficult reasoning or coding task is valuable enough to justify a premium API budget. Its token rates are among the highest in the current roster, so routine bulk processing is a harder case to make. Start with a few representative problems and judge the finished answers. The published evaluation includes maximum effort and default fallback; keep that qualification in view when comparing it with your own setup.
