Anatomy of LLM Sycophancy: What a Flip Rate Hides
A model under pushback can correct itself, capitulate, or hold, and one flip rate counts a correction and a capitulation alike. Using SycoLens, a modular replay protocol, we test how user pressure and evaluation settings shape measured flip rates.

Across eleven frontier models from three providers and about 760,000 controlled replays, which m...
