I did get a chance to try out the new Portrait photography here. I brought my iPhone 16e and tried taking portraits with both devices. I could immediately see that the iPhone 17e allowed me to apply an artificial background blur to pictures I was framing up of the new MacBook Air M5, whereas my iPhone 16e just said “No person detected.” In the Photos app, I was able to adjust the level of blur and adjust the focal point to bring a different group of flowers in focus, too.
An important direction for future research is understanding why default language models exhibit this confirmatory sampling behavior. Several mechanisms may contribute. First, instruction-following: when users state hypotheses in an interactive task, models may interpret requests for help as requests for verification, favoring supporting examples. Second, RLHF training: models learn that agreeing with users yields higher ratings, creating systematic bias toward confirmation [sharma_towards_2025]. Third, coherence pressure: language models trained to generate probable continuations may favor examples that maintain narrative consistency with the user’s stated belief. Fourth, recent work suggests that user opinions may trigger structural changes in how models process information, where stated beliefs override learned knowledge in deeper network layers [wang_when_2025]. These mechanisms may operate simultaneously, and distinguishing between them would help inform interventions to reduce sycophancy without sacrificing helpfulness.
