A new ranking of the top 10 Large Language Models (LLMs) for October 2026, based on the Artificial Analysis Intelligence Index v4.3.2, reveals significant discrepancies between overall scores and practical performance metrics like latency and cost. While the top-ranked model boasts a high score, its first-token latency is over 12 minutes, contrasting sharply with a second-ranked model that achieves a first-token response in under a second. The analysis also highlights that model availability can be an issue, with some ranked models not being directly callable, and that cost does not scale linearly with performance, with some models offering substantial performance gains for a fraction of the price.
