These are exciting times with open models. With Kimi K3, we now have a model that offers intelligence that is comparable to Opus 4.8 and GPT 5.5. It has an ELO rating of 1668 on GDPval v2, which is better than Opus 4.8, GPT 5.5, and GLM 5.2. Moonshot AI is going to release the 2.8T model’s weights, which means Kimi K3 will become the leading open weight model.
Kimi K3 scores 57 on the Artificial Analysis Intelligence Index. Its intelligence is comparable to Opus 4.8 and GPT-5.5 but remains behind Fable 5 and GPT-5.6 Sol.
