Apple will host its annual fall event on September 9, according to an invite on Tuesday, where the company is expected to unveil new iPhones, watches and other devices.

The event will be held at the Steve Jobs Theater at Apple's headquarters in Cupertino, California and serve as a showcase of the company's efforts to integrate artificial intelligence into its devices.

It will be closely watched by investors worried about the company ceding ground to faster-moving rivals in the race to deploy AI technology.
