It can be used on fixed-line phones and WhatsApp as well as ChatGPT and smartphones.

ChatGPT is now available not only on smartphones but also on regular landline phones and social media WhatsApps.

OpenAI said ChatGPT can answer users' questions and translate sentences into other languages by calling "1-800-242-8478" (1-800-CHATGPT).

ChatGPT's advanced voice mode for more natural conversation is supported, but images and videos are not supported.

OpenAI explained that it will offer free 15-minute calls to U.S. users, after which regular carrier charges may apply.

"OpenAI's goal is to create general-purpose artificial intelligence (AGI) that is beneficial to mankind and increase accessibility to many people," he said. "We brought ChatGPT to the next step, the phone."

ChatGPT will then be available on WhatsApp, one of the most popular SNSs in the world with 2 billion monthly active users.

WhatsApp users can have basic Q&A conversations with ChatGPT as ChatGPT is installed on WhatsApp, the SNS of Facebook parent Meta Platforms.

OpenAI has introduced the "Chat GPT Pro" with a monthly pricing plan of $200 and the "Sora" and "Visual" functions of video generation AI, and explained that it will also provide additional image analysis and web search functions in the future.
