ChatGPT yesterday

OpenAI launched a free ChatGPT app for US iPhone users yesterday, representing the first official mobile version of its revolutionary AI chatbot.

📱🤖 How it works: Like the website, users must first log in after downloading to access the chatbot. But unlike the website, ChatGPT’s new smartphone app now accepts voice inputs as well as text, similar to Apple’s Siri or Amazon’s Alexa (or the robot from Her, which doesn’t scare us at all).

• All US iPhone users running iOS 16 can access ChatGPT’s base features, aka GPT-3.5, by downloading the app and creating an account for free.
• OpenAI also offers a $20/month subscription that gives mobile and/or desktop users access to the improved GPT-4 chatbot, which has a range of upgrades over the free version including faster response speeds and increased input capacity (25,000 words, up from 3,000).

The ChatGPT iPhone app began rolling out to US users yesterday, and will expand to other countries within the next few weeks. A version of the app for Android phones is also coming “soon,” OpenAI said.

📈 Big picture: ChatGPT first launched to the public on November 30. It quickly became the fastest-growing consumer application in history, per investment bank UBS, attracting an estimated 100 million users within the first two months – far faster than second-place TikTok, which took nine months to reach a user base of that size.
