ArtificialAnlys · x · 2026-07-28
Artificial Analysis says Kimi K3 has pushed open-weights intelligence forward again, cutting the gap to the leading proprietary models to 4 points — the smallest margin since the GLM-5 release in February.
According to the new ranking, Kimi K3 scores 57 on the Artificial Analysis Intelligence Index. Only two labs are ahead: Anthropic with Claude Opus 5 at 61 and Claude Fable 5 at 60, and OpenAI with GPT-5.6 Sol at 59. The chart also shows the open-weights line continuing to close in on proprietary models over time.
