Kimi K3 scored 57 on the Artificial Analysis Intelligence Index, with an intelligence level comparable to Opus 4.8 and GPT-5.5, but still behind Fable 5 and GPT-5.6 Sol. Artificial Analysis is widely regarded in the industry as one of the most independent and rigorous AI model benchmarking platforms. Reaching this level is already impressive. As an open-source large model that can rival the previous generation flagship products of cutting-edge closed-source models, it's already pretty awesome.
