Amazon is entering a new phase under Andy Jassy, using AI to streamline its workforce. The move continues a broader effort to reshape the company from within.

Amazon is currently using AI to optimize inventory in its fulfillment network, upgrade its customer service chatbot and improve product detail pages.

Amazon is warning its employees that artificial intelligence will help the company have a smaller workforce in the future. In a blog post Tuesday that was sent out earlier to employees, Amazon CEO Andy Jassy said that efficiency gains from AI would allow the company to eventually have a reduced human workforce.
