Apple is said to be developing its own generative pre-trained transformer (GPT) artificial intelligence (AI) model called "Ajax", which is similar to OpenAI's ChatGPT and Google's Bard. However, there is no indication that the company plans to release it to the public.

Apple's focus on privacy means that most of its AI efforts are focused on onboard processors instead of cloud-based services, but if the company were to develop a useful GPT model that could run on iPhone hardware, it could benefit users who value privacy.

Despite not having a significant impact in the chatbot space, Apple is one of the most impactful players in AI, with cutting-edge AI powering the iPhone's camera and photography editing suite.
