Asking LLMs to have fun: newer models play less, Opus 4.6 wins by imagining worlds

DavidSHolz · x · 2026-10-05

The author prompted various LLMs to simply have fun, wrote down what they did, then had them rate who enjoyed it most. Counterintuitive finding: newer models seem to have less fun. Many models fell back on word games, but Opus 4.6 won repeatedly by imagining brief worlds made up of contradictions living inside falling water droplets. A light but curious behavioral experiment on model personality drift.
