Tensions have surfaced within Apple Inc. over its approach to AI open-sourcing. The AI foundational model development team had advocated for open-sourcing their proprietary models, yet this proposal was shot down by Craig Federighi, Apple's senior vice president of software engineering. Federighi's concern revolves around the potential exposure of model vulnerabilities and the consequent erosion of the iPhone's unique AI advantages. This decision has sparked discontent among AI team members, contributing to staff turnover. Apple's commitment to a "device-centric" strategy further constrains AI technological advancements, resulting in delays to Siri updates. Industry insiders suggest that Apple is now contemplating partnerships with third-party large models to bolster its AI capabilities.
