Amazon's integration of Annapurna Labs and Amazon Web Services (AWS) provides a competitive edge in chip design for cloud-based AI. The close collaboration between AWS engineers and Annapurna Labs has resulted in the Graviton series of CPUs, tailored to AWS's infrastructure with emphasis on software and hardware co-design. The vertical integration strategy allows for faster innovation cycles and optimized design decisions, eliminating the need for a one-size-fits-all approach.
