OpenAI will now give you the ability to dial up — or down — ChatGPT’s warmth and enthusiasm. An update rolling out on Friday gives you the option to choose whether you want “more” or “less” of these personality traits, or stick with the default.

There are also options to tweak how often ChatGPT uses emoji, headers, and lists. You can find these settings by tapping the menu at the top left corner of the ChatGPT app, selecting your profile, heading to Personalization, and choosing Add Characteristics. Alongside these options, you can pick a “personality” for the AI chatbot, including whether it’s quirky, professional, friendly, cynical, and more.

Another update changes the way you write emails with ChatGPT, as you can now update and format text directly inside the chat. You can also highlight chunks of text and ask ChatGPT to make specific changes to it, rather than attempting to direct ChatGPT to that section in a separate prompt.
