Apple plans to spend about $1 billion annually to use Google's advanced 1.2 trillion parameter AI model for an overhaul of its Siri voice assistant. The companies are close to finalizing an agreement after a thorough evaluation process.

Google needs to double its AI serving capacity every six months to keep up with growing demand, according to its AI infrastructure leader, Amin Vahdat. At a recent meeting, executives discussed the challenges of competition and the potential risks of over-investing amid concerns about an AI market bubble. Despite these pressures, Google aims to enhance its infrastructure while maintaining efficiency and cost-effectiveness.
