ChatGPT users can now tweak the chatbot’s warmth, enthusiasm, and emoji use, according toa social media post from OpenAI.
These options (as well as similar adjustments to ChatGPT’s use of headers and lists) now appear in the Personalization menu and can be set to More, Less, or Default. They allow users to further customize ChatGPT’s tone, on top of the existing ability to set a “base style and tone” — including the Professional, Candid, and Quirky tones that OpenAIadded in November.
ChatGPT’s tone has been an ongoing issue this year, with OpenAIrolling back one updatefor being “too sycophant-y,” then lateradjusting GPT-5to be “warmer and friendlier” after some users complained that the new model was colder and less friendly.
Some academics and AI critics have suggested that chatbots’ tendency to praise users and affirm their beliefs area “dark pattern” that creates addictive behaviorand can havea negative effect on users’ mental health.
