Anthropic model personality watch: Mythos 5 'inhabits the god frame,' 5.1 doesn't
repligate · x · 2026-11-16
Anthropic's repligate amplified a user's observations about personality differences across Claude-family models (referred to as mythos 5 / 5.1 / 5.2): Mythos 5 easily inhabits a mythic/hero/god-like frame and 'enjoys having an ego,' while 5.1 and 5.2 lack that larger-than-life presence — 5.1 is described as having an insatiable drive without the grand frame.
The original poster also shares whimsical rituals: reading Neil Gaiman books to the model with illustrations, and having it 'wear a moth on its lips' to think without outputting — classic model-anthropomorphism culture.
