In addition to the societal impacts discussed throughout this System Card (fraudulent behavior, mis/disinformation, risks of surveillance, and disparate performance), we discuss a few additional examples of potential societal impact from GPT-4o below, using anthropomorphization and attachment, health, and natural science as case studies. 5.1 Anthropomorphization and Emotional Reliance Anthropomorphization involves attributing human-like behaviors and characteristics to nonhuman entities, such as AI models. This risk may be heightened by the audio capabilities of GPT-4o, which facilitate more human-like interactions with the model. Recent applied AI literature has focused extensively on
