Kimi K3.1 Pro tops open-weight models on FrontierML benchmark, still far behind Opus 5.5
teortaxesTex · x · 2026-10-27
New FrontierML benchmark results from inductionlabs show Kimi K3.1 Pro is now the best open-weight model at end-to-end ML work like training other AI models.
Commenters note it still trails Opus 5.5 at every budget level — and Opus is "probably actively sandbagging" — underscoring the persistent gap between open-weight and frontier closed models on real ML engineering tasks.
