In the FrontierCode v1.1 row, Anthropic highlighted Opus 5's 53.4% as if it were the best result. Fable 5 scored 53.5%—0.1 percentage points higher.
The two scores are effectively tied, but the visual treatment still contradicts the numbers. A winner's highlight belongs on the higher score—or on neither score when the difference is too small to emphasize.
Anthropic later corrected the graphic, moving the highlight to Fable 5's 53.5%. The cover image preserves the version before the correction.
