According to PANews, Apple reached a cooperation agreement with OpenAI this week to integrate ChatGPT into iPhone, iPad and Mac devices. People familiar with the matter revealed that Apple did not pay OpenAI for the cooperation, but believed that the value of promoting OpenAI's brand and technology to hundreds of millions of Apple devices was equal to or even higher than direct payment. ChatGPT will be available for free on Apple devices, but OpenAI and Apple can make a profit by converting free users into paying users. OpenAI's subscription plan starts at $20 per month, which includes additional features such as analyzing data and generating more types of images.
