Study probes persona consistency by simulating eating-disorder patients with LLMs

arXiv·low signal

arXiv:2606.26109 (June 26) tests how well LLMs hold a consistent psychological persona across extended agent conversations by simulating eating-disorder patients. The work surfaces where long-horizon persona fidelity breaks down — a recurring failure mode for character and companion agents. Builders of long-running conversational agents should note persona drift as a measurable, not just anecdotal, problem.
