Opus 5.5 still leads a month later, but open-weight decision models are closing in
airesearch12 · x · 2026-10-16
Responding to the claim that Opus 5.5, nearly a month after release, still beats everything and shows how far ahead Anthropic is, @airesearch12 offers a counterpoint: that holds for LLMs, but decision models are smaller, so no big capital is needed to stay competitive — and open-weight models already lead many leaderboards in those categories. Anthropic's edge is largely confined to frontier LLMs.
