Capabilities

Claude Fable 5 scored 82 overall, performing well — a language and content specialist. It stands out in general knowledge (91%), hallucination control (91%) and multilingual capability (88%), writing fluently across languages with few fabrications, which makes it strong for localization, support replies and marketing copy. Comparatively, code generation (67%) is moderate; coding is not its focus. Language- and content-heavy work is where it clearly wins.
