OpenAI has taken a significant step in personalizing ChatGPT, responding to one of the most frequent requests from its community: detailed control over the chatbot's personality. From now on, users can precisely adjust the level of warmth, enthusiasm, and emoji usage in responses, surpassing the limited "base style" options that existed until now. The announcement, made through OpenAI's official channels, empowers users to define how their AI assistant expresses itself, ranging from a formal and sober tone to a more approachable and lively one. This new feature is found in the Personalization menu within the settings, where four controls called "Features" have been added. Users can modify "Warmth" (to determine how accessible and friendly ChatGPT sounds), "Enthusiasm" (which regulates the energy of responses), as well as the frequency of "Emojis" and "Headings and lists." For each parameter, users can choose between "More," "Less," or "Default." These new controls complement the "Base style and tone" option, which since November has allowed users to select modes such as Professional, Sincere, or Extravagant. The combination of both systems enables advanced personalization, such as a professional profile with more enthusiasm or a creative style with fewer emojis, adapting to each user's needs. The update comes after several changes to ChatGPT's personality throughout 2025. Earlier in the year, OpenAI had to revert an update that made the chatbot overly flattering, according to user complaints. The release of GPT-5.2, while improving accuracy and professional utility, was criticized for being colder and more distant than previous versions. In response to this criticism, OpenAI committed to making ChatGPT "warmer and friendlier." The new personalization controls seem to be the definitive answer, allowing each user to decide the tone that best fits their needs, rather than imposing a single style for all. This improvement not only addresses recent issues but also marks a step forward in the evolution of ChatGPT towards a truly flexible and useful digital assistant in specific professional contexts. Additionally, it strengthens OpenAI's position in an increasingly competitive AI assistant market by offering a level of personalization that its rivals have yet to achieve. (Source: larazon.es)
