Apple's AI foundation model team had initially envisioned open-sourcing several self-developed models as a means to showcase technological advancements. However, this proposal was rejected by Craig Federighi, Apple's Senior Vice President of Software Engineering. Federighi's concern centered around the potential exposure of performance shortcomings in the models, which he feared could undermine the iPhone's competitive edge in AI. This decision has stirred discontent within the team, prompting the exit of some of its top AI experts. Apple's steadfast commitment to a "device-first" approach may be hindering its ability to attract and retain top AI talent in an increasingly competitive landscape.
