R&D World reports that Kimi K3.1 Pro scored 55 on Artificial Analysis’s intelligence index, ranking fourth among 215 models, with a reported cost of $2.11 per task. That makes performance-versus-cost comparisons relevant, but the aggregate result does not imply leadership everywhere: scientific terminal tasks and other categories still showed gaps from leading systems. Costs and speed also depend on evaluation timing and output-token usage. These external results are distinct from the developer’s claims at launch; the numerical findings here come from the accessible report because the benchmark page did not expose its chart values.
