Strengths

  • Source-backed model profile

Limitations

  • Restricted trusted-access programs
  • Fable 5.1 uses the same underlying model with different safeguards; evaluation scores cannot be copied between configurations
Task lenses preserve raw scores. Radar axes use score / current leader × 100; overall is the equal-weight average of all five indices. Missing evidence is not a zero or a low rank.
