The best AI models for writing — drafting, editing, long-form content and creative work — ranked by general capability (the Artificial Analysis Intelligence Index) among models with the context to hold a full draft. There is no single writing benchmark, so this ranking uses overall intelligence as the proxy that correlates best with prose quality, restricted to models with at least 100K tokens of context.
