A new free phone app, ChatGPT, has introduced a feature called "Santa Mode," allowing users to converse with an AI version of Santa Claus just before Christmas. The festive upgrade, part of OpenAI's 12-day campaign, enables iPhone and Android users to interact with a voice mimicking Hollywood's depiction of Santa. Aimed at families, the feature emphasizes accessibility and fun, while raising ongoing discussions about AI's impact on society and various industries.
