To summarise the full results table further down the page (which doesn't render on the page for me!):

  Kimi K3 beats each model (out of 35 benchmarks, excluding missing):
  vs Fable 5           : 12/35 (34%)  (ties: 1)
  vs GPT 5.6 Sol       : 19/34 (56%)  (ties: 1)
  vs Opus 4.8          : 30/35 (86%)
  vs GPT 5.5           : 30/34 (88%)  (ties: 2)
  vs GLM-5.2           : 19/19 (100%)

Beats Opus 4.8 and GPT 5.5 on all programming and agentic programming benchmarks except Toolathlon-Verified, often by a lot!
