Apple is secretly working on AI tools and an internally used AI chatbot, Bloomberg reports, which engineers in the company have nicknamed "Apple GPT."

The news could be the first serious sign that the tech monolith is finally entering the generative AI race, though it reportedly has no plans to release its product anytime soon.

According to Bloomberg, an experimental version of Apple's chatbot was created by a small team before the end of last year. Though "Apple GPT" has gradually been used by more engineers, the company is keeping access to it tight over security concerns. Intriguingly, employees have been forbidden from using the chatbot to develop products that will be used by customers.
