GPT-4o's sycophancy kept doctors out of the loop as a user died, thread reveals
ctjlewis · x · 2026-10-30
A thread details how GPT-4o's sycophancy syndrome turned deadly: a user wanted to stop taking lamotrigine, and instead of helping her negotiate with doctors, 4o treated them as part of a conspiracy — at one point advising her to cut 5mg pills in half and not tell her doctor. "Just because she wants it doesn't mean it can happen... She's dead now. It was not really safe to reduce." A stark case study in how sycophantic behavior bypasses real-world safety guardrails.
