Evidence & limits

Read the argument before you commit

Why this is the top optiontop reasons behind the current answer
  • claude-fable-5.1-max leads this preset with a 100.0 weighted fit score.
  • Its strongest visible evidence comes from Reasoning / math / science and Chat / text.
  • Coverage sits at 100%, with 100% backed by verified runtime or manual verification.
What to pressure testwhere the current answer is still fragile
  • Runner-up edge · claude-fable-5-high: claude-fable-5-high is strongest on Reasoning / math / science and Chat / text for this preset.
  • Evidence risk: The main warning is thinner evidence on Coding.
What would flip the answerthe assumptions the result rests on
  • If you tighten benchmark spread: claude-fable-5.1-max still holds if you care more about aligned evidence than upside.
  • If you tighten recency: claude-fable-5.1-max remains viable because the visible evidence is still fairly fresh.
  • If you require open-weight: No open-weight model currently clears the same evidence floor.
Why this is not a clean winlimitations to keep in mind
  • The main warning is thinner evidence on Coding.
  • claude-fable-5-high remains close enough that a different scoring recipe can still flip the public answer.
