Apple is reportedly considering integrating third-party AI models from companies like Anthropic or OpenAI into its revamped Siri, according to Mark Gurman. This move comes after Apple's well-documented difficulties in enhancing Siri's capabilities with its own AI technology. Utilizing external AI models could provide Apple with a faster and more effective solution for improving Siri's performance and user experience, potentially bypassing the challenges they've faced in developing their own advanced AI.
