- The company appointed Amar Subramanya as vice president of artificial intelligence with immediate effect, reporting to Senior Vice President Craig Federighi.
- Subramanya will lead Apple Foundation Models, machine learning research, and AI safety and evaluation, consolidating core responsibilities in a single team.
- Apple reassigned remaining functions from Giannandrea’s organization to Sabih Khan and Eddy Cue, and noted that the Siri project is currently led by Mike Rockwell, who also reports to Federighi.
