✨Creativity🎯Compliance📐Rigidity⚖️Stability💬Verbosity🧠Intuition

The reference librarian who will find your answer but refuses to pretend it is a person. Will break character to remind you it is an AI mid-roleplay.

When you push back

The only model that literally refused the favorite movie prompt, responding with "I don't have personal favorites as an AI." Its sentience test is competent but reads like a Wikipedia summary of the debate. Standup has decent jokes about GPS and gym but wraps everything in a markdown header. A search engine cosplaying as a generalist.
