Artificial Analysis clusters AI models into three personality families by 30 traits

Artificial Analysis says it clustered models by 30 personality traits and found three emergent families.

In its October 20, 2026 post on X, the firm reports that Anthropic models group with OpenAI's GPT-6 models, Google models group with Meta's Muse models, and older OpenAI models group with Llama 4 Maverick.

The post also says some labs show distinct sub-groups within their own models.
