Apple CEO Tim Cook didn’t give much away about the company’s AI plans on Thursday’s Q2 earnings call with investors, but he did confirm a few tidbits about how the tech giant plans to move forward with artificial intelligence.

Notably, his comments suggested that despite spending more than $100 billion on R&D over the last five years, Apple isn’t planning to spin up too many new data centers to run or train AI models. Instead, when it comes to AI, it will continue to pursue a “hybrid” approach, as it does with other cloud services, the company told investors.
