Briefings

Artificial Analysis Intelligence Index v5 was released on October 28, 2026, marking a major update that significantly widens the performance gap between open-weight and closed-weight models. The new index incorporates 60% of evaluations from private test sets or held-out answers, rendering results unrepeatable for users. Kimi K3.1 Pro is identified as the top open-weight model at 46 points, while DeepSeek V4.1 Flash 1017 and GLM-5.3 lead released weights at 32 and 26 points respectively, trailing Claude Haiku 5.5 at 36 points.

Key points

• The Artificial Analysis Intelligence Index v5 is a major update released on October 28, 2026, which significantly widens the performance gap between open-weight and closed-weight models.
• Kimi K3.1 Pro is identified as the top open-weight model at 46 points, while DeepSeek V4.1 Flash 1017 and GLM-5.3 lead released weights at 32 and 26 points respectively.

Context

This update is part of a series of AI model evaluations conducted by Artificial Analysis Intelligence, with findings shared on r/LocalLLaMA. The index aims to provide a more accurate ranking of large language models by incorporating more rigorous private test set evaluations.

Limitations

The index relies on 60% of evaluations from private test sets or held-out answers, making it impossible to reproduce results. The specific ranking of Kimi K3.1 Pro as the top open-weight model is based on unverified data from the source community.
