OpenAI, an American artificial intelligence research laboratory, has launched an iOS app for ChatGPT built on GPT-3.5, a free-to-use version similar to the original web model that was released six months ago. Current ChatGPT Plus subscribers will have exclusive access to GPT-4’s features and faster response times on iOS. The new mobile app synchronizes the user’s chat history with its bot across devices and features voice input supported by the company’s open-source speech recognition model Whisper. At launch, the app is only available in the US, with plans to expand to other countries in the coming weeks, followed by Android device expansion. Although OpenAI did not hint at a new mobile incarnation, the move is unsurprising since ChatGPT’s popularity has skyrocketed in a very short span of time. The chatbot attracted 100 million users just two months after launching, with nearly 590 million visits in January. OpenAI made it accessible to the public for free last November, just five days after which ChatGPT acquired a million users, surpassing Instagram’s achievements in 2.5 months and Netflix’s in over three years. Recently, ChatGPT predicted scenarios on what could happen in the digital asset space within the next decade. The roaring success of ChatGPT has ignited a frantic rush to release new AI products to market, with various tech giants and startups such as Google and Baidu working on their own AI chatbots.
