In a recent announcement, Apple revealed that its artificial intelligence models powering Apple Intelligence were trained using processors developed by Google. This decision signifies a shift in the industry as major tech companies seek alternatives to Nvidia for cutting-edge AI training. Apple’s adoption of Google’s Tensor Processing Unit (TPU) for training was outlined in a newly published technical paper, showcasing a strategic move towards diversifying hardware providers.
Nvidia has long been the dominant player in the market for high-end AI training chips with its expensive graphics processing units (GPUs). However, the surge in demand for Nvidia’s GPUs over recent years has resulted in supply shortages, prompting companies like Apple to explore other options. Apart from Nvidia, tech giants such as Google, Meta, Oracle, and Tesla have also been investing in AI infrastructure to enhance their capabilities.
Although Apple refrained from explicitly mentioning Google or Nvidia in its 47-page paper, the company indicated that its Apple Foundation Model (AFM) and AFM server were trained on “Cloud TPU clusters.” By leveraging cloud-based servers, Apple was able to efficiently scale its AI training models, including both on-device and server-based applications. The strategic partnership with Google allowed Apple to harness the computational power of TPUs for accelerating its AI system development.
Apple Intelligence Features
On the heels of its industry peers, Apple recently unveiled Apple Intelligence, a comprehensive AI system encompassing several innovative features. The platform boasts a revamped Siri interface, improved natural language processing capabilities, and AI-driven text summaries. Additionally, Apple outlined plans to introduce generative AI functions, such as image and emoji generation, alongside an enhanced Siri experience that integrates personal data and enables in-app actions.
Google’s TPUs have emerged as a cost-effective alternative to Nvidia’s GPUs, with the latest version priced at under $2 per hour when booked for extended periods. Originally developed for internal workloads in 2015, Google’s TPUs have evolved into mature custom chips optimized for artificial intelligence tasks. Despite this progress, Google remains one of Nvidia’s key customers, utilizing a mix of TPUs and GPUs for AI training and offering access to Nvidia’s technology through its cloud services.
Apple’s decision to incorporate Google’s TPUs into its AI training process aligns with the company’s broader strategy of leveraging in-house hardware for AI inference tasks. By partially offloading inferencing to its proprietary chips in data centers, Apple aims to enhance the efficiency and performance of its AI models. The recent technical paper on Apple’s AI system represents a step towards building a robust foundation for future advancements in artificial intelligence.
Apple’s collaboration with Google for AI training using TPUs underscores the evolving landscape of hardware choices within the tech industry. As companies seek to overcome supply chain challenges and optimize computational resources for AI development, strategic partnerships and diversification of hardware providers will continue to shape the future of artificial intelligence. This shift towards innovation and flexibility reflects a broader trend towards enhancing AI capabilities through strategic hardware investments.
