RadLE 2.0

Claude Fable 5 758.0 leads since July 2026
Not in model cards

Models diagnose single-image radiology cases with a confidence score from 0 to 4, or say they do not know. A confidence-weighted index rewards right answers and penalizes confident errors.

The primary metric RadLE-C runs from 0 to 2000. It is larger than 1.0 and adds open-source and medical vision-language models, so scores do not compare.
