Apple has confirmed its use of Amazon Web Services’ (AWS) custom AI chips, including Inferentia and Graviton, for services such as search and Siri. At the annual AWS Reinvent conference, Apple’s senior director of machine learning and AI, Benoit Dupin, detailed how these chips have improved efficiency by 40%. Dupin also revealed that Apple is evaluating AWS’s Trainium2 chip for pretraining its AI models, anticipating a potential 50% efficiency gain.

AWS CEO Matt Garman noted that Apple has been an early adopter of Trainium chips, leveraging the infrastructure for its “Apple Intelligence” generative AI capabilities. Apple’s collaboration with AWS underscores the growing competition among cloud providers, with AWS vying against Microsoft Azure and Google Cloud in the AI space.

Apple has used AWS for over a decade for various services, including Apple Maps and Apple Music. While the company also utilizes NVIDIA GPUs and Google Cloud TPUs, its interest in AWS’s custom chips signals a broader trend of exploring cost-effective alternatives in AI infrastructure.
