In a significant reversal of strategy, Apple is reportedly considering utilizing external AI models from OpenAI and Anthropic to enhance its Siri voice assistant. As the tech giant faces challenges in developing its in-house AI capabilities, engaging with established AI firms may allow Apple to deliver advanced features for Siri without the need for extensive investment. This decision has positively impacted Apple stock, which rose 3% following the news. Observers describe this as a crucial moment for the company as it aims to regain its competitive edge in the rapidly evolving AI landscape.
