Apple is set to integrate OpenAI's ChatGPT into its products with the iOS 18.2 update, enhancing Siri and other features with advanced AI capabilities. This partnership allows Apple users to upgrade to ChatGPT Plus directly through the Settings app, offering a premium subscription for USD20 a month. While this could significantly boost OpenAI's revenue, as the free version of ChatGPT has limitations, the financial dynamics of the deal remain unclear. Apple isn't paying OpenAI directly but is providing exposure, which could lead to increased ChatGPT Plus signups. However, if users don't subscribe, OpenAI might face higher AI inference costs due to a surge in free users. It's uncertain if Apple will take a share of the revenue from these signups, but the company is also exploring AI integrations with other developers like Google. Meanwhile, OpenAI is navigating financial challenges and executive departures, with Apple reportedly withdrawing from a recent funding round.
