Artificial Analysis scores open-weight Nanbeige4.3-33B 20 on its Intelligence Index, level with Qwen3.8 27B

Artificial Analysis says Nanbeige4.3-33B, the open-weight model from Nanbeige (the foundation-model team at the Chinese hiring platform BOSS Zhipin), scores 20 on its Intelligence Index v5, the same as Qwen3.8 27B (xhigh). Both are dense models, with 33B and 27B total parameters. Artificial Analysis says Nanbeige's model has stronger terminal use but weaker knowledge, and sets a new Pareto-optimal point for Intelligence Index against total parameters.

According to Artificial Analysis:

• Knowledge: on AA-Omniscience v1.1 the model's hallucination rate is 18%, against 29% for Qwen3.8 27B, because it answers selectively: an attempt rate of 29% against 43%. Qwen answers more questions correctly overall, 17% against 12%.
• Tokens: Nanbeige4.3-33B used 158K output tokens per Intelligence Index task, against 110K for Qwen3.8 27B, 44% more for the same score. The figure covers answer and reasoning tokens across the nine v5 evaluations, including agentic tool-use turns.

The weights are on Hugging Face. These are Artificial Analysis's own measurements; Nanbeige released the model on October 25.
