ChatGPT update lets users customize a 'warmer' and more enthusiastic bot

ChatGPT can act even friendlier now, with new personality customization options that let users choose just how warm and enthusiastic the bot is in conversation.

OpenAI announced the new personality settings in a Friday post on X. The update rolled out immediately to ChatGPT users alongside a long-awaited pinned chats feature, new ways to generate or edit emails, and updates to ChatGPT browser Atlas.

The new tools add more fine tuning of ChatGPT's personality using levels of warmth and enthusiasm (labelled as "more," "less," or "default"). Users can also adjust the way the bot organizes its responses, such as how frequently it generates lists, as well as the amount of emojis it employs, in addition to its base style and tone. There's still no option to exclude emojis entirely.

Professionals have warned that overly anthropomorphic and sycophantic chatbots can exacerbate mental health concerns, including AI psychosis and dependency. A previous ChatGPT model, the still-available GPT-4o, was adjusted earlier this year after facing criticism for "overly agreeable" behavior. CEO Sam Altman has referred to the issue as a "personality problem."

OpenAI launched its new GPT-5.2 model series one week ago, boasting new capabilities for "professional knowledge work" that include better processing benchmarks and less hallucinations, the company reports.

ChatGPT's developers also recommitted itself to its mental health and teen safety promises amid escalating lawsuits. In a blog post published Thursday, OpenAI explained it was introducing a new set of under-18 user principles to GPT-5.2 intended to create additional guardrails around sensitive topics and encourage age-appropriate interactions. It's also working on a new age verification system for young users. GPT-5.2 reportedly scores higher on internal mental health safety tests, including stress testing for self harm, than previous models.
