Apple Inc.’s top executive in charge of artificial intelligence models is leaving for Meta Platforms Inc., another setback in the iPhone maker’s struggling AI efforts.

Another setback for the iPhone maker could put its AI future in jeopardy, or push it even closer to using models from OpenAI or Anthropic instead of developing its own.

Apple has reportedly lost its top executive in charge of artificial models to Meta Platforms, as the Facebook parent continues to build up its new “Superintelligence” AI division.
