PANews reported on December 19 that according to the official announcement of OpenAI, ChatGPT now supports interaction with users over the phone. US users can call the exclusive number 1-800-CHAT-GPT (1-800-242-8478), which supports landlines and old mobile phones. This feature is also integrated with WhatsApp, and users can send information consultations through this number, which is similar to the existing Web and mobile versions. Currently, US users can use 15 minutes of voice calls for free each month, and specific rules and restrictions may be adjusted. OpenAI said that in order to get a more comprehensive experience and use more features (such as search, higher limits, and more personalization), existing users should continue to use ChatGPT directly through their accounts.
