Apple and OpenAI have entered into a partnership to integrate ChatGPT into iOS 18 without any direct financial transactions between the companies. Instead, Apple will offer exposure to OpenAI's technology, potentially leading users to subscribe to ChatGPT Plus. This move could impact Apple's search revenue from Google. The deal signifies OpenAI's shift from a non-profit research lab to a for-profit company aiming to become a major consumer tech giant. Apple users will get free ChatGPT use, and no data will be allowed to be used in exchange for awareness. The partnership is seen as a strategic effort for both companies to leverage each other's strengths and expand their user base.
