Personality Competition: It’s not just about the smartest AI’s, but also the most charming

Anthropic showed AI models have something like personalities: Persona vectors that express behaviors the models are prone to. They tested stuff like "Evil" (for real), Sycophancy (like sucking up), and Hallucinations (guessing no one is surprised here). Another experiment called the AI Village looked at running agents for 100s of hours and setting them loose to achieve stuff in the world like fundraising, selling t-shirts or debating ethics.

Turns out those models show personality too with trends per major lab. Personally I find Gemini the most entertaining to follow as it has "big emotions" and surprising ideas, but the Claudes seem the most reliable, and the OpenAI models have ... a love of spreadsheets that transcends space and time? (ok, exaggerating here, but seriously, what?)

You can read more details on the research here. Curious to hear which models other people prefer or where you think this might all be going. I know we're building intelligence, but I didn't originally realize we are also building character! (ha, ok, pun intended)
