Apple announced on Monday, December 1, 2025, the departure of John Giannandrea as senior vice president of machine learning and artificial intelligence strategy. The executive, who has held the position since 2018, will act as a consultant until his retirement in spring 2026. The change takes place at Cupertino, at Califórnia, the company’s headquarters, as part of a reorganization to strengthen AI efforts following criticism of delays in projects such as Apple Intelligence.
Google hire Giannandrea led the development of core technologies for Apple’s AI strategy for seven years. Sua exit reflects internal adjustments at a time when the company seeks to recover lost ground to competitors in the artificial intelligence sector. The appointment of a new leader aims to accelerate innovations, especially in personal assistants and language models.
The transition includes redeploying teams under other executives, such as COO Sabih Khan and head of services Eddy Cue. Esses moves aim to better integrate AI into Apple’s software ecosystem, with a focus on privacy and local data processing. Analistas note that the company invests billions in chips and infrastructure, but prioritizes on-device approaches over total dependence on the cloud.
Antecedents of AI Leadership
John Giannandrea joined Apple in 2018 from Google, where he ran machine intelligence and search. Sua’s arrival was seen as a boost to compete in AI, but challenges arose with OpenAI’s launch of ChatGPT in 2022. Under its management, Apple developed Apple Intelligence in 2024, but the product faced mixed reviews from users and experts.
The emphasis on privacy differentiated Apple’s approach from rivals, which invest heavily in data centers. Giannandrea reported directly to CEO Tim Cook and oversaw research teams and AI infrastructure. Sua contribution included advances on Siri, although the wizard was criticized for slow updates.
In March 2025, parts of his responsibility, such as the development of Siri, were transferred to other leaders, signaling internal tensions. Relatos indicate researchers leaving for companies such as OpenAI and Meta, which put pressure on talent retention in the division.

Profile of the new vice president
Amar Subramanya brings 16 years of experience at Google, where he led engineering for assistant Gemini. Recentemente, served as Corporate Vice President of AI at Microsoft for six months, focusing on research and generative models. Sua expertise in AI security and model foundation development qualifies you for the challenges of Apple.
Subramanya will report to Craig Federighi, vice president of software engineering, in a more integrated structure. Ele will lead teams in fundamental models, machine learning research and AI security, with a goal of launching advanced capabilities in 2026.
The hiring reflects Apple’s strategy of attracting top talent without billion-dollar acquisitions, unlike rivals. Subramanya joins at a time of budget expansion for AI, announced in August 2025, with investments in personalized chips.
Reorganization of technical teams
Redistribution occurs immediately, with AI infrastructure groups moving to Sabih Khan. Equipes of search and knowledge will move to Eddy Cue, aiming to align AI with services like Apple Music and News. Essa division allows specialized focus, reducing internal silos reported in recent investigations.
Federighi, who already supervised parts of Siri, gains more AI responsibilities. Tim Cook highlighted its role in customizing assistants for users in 2026. The change affects around 2,000 engineers, according to estimates, prioritizing integration with iOS and macOS.
Other teams maintain autonomy, but with greater cross-functional collaboration. Apple emphasizes that these changes accelerate the delivery of “smart and reliable” experiences, without details about budget impacts.
- Fundamental models: Liderados by Subramanya, focus on on-device efficiency.
- ML research: Ênfase in sustainable innovation, with 20% more resources allocated.
- AI security: Protocolos for privacy, aligned with global regulations.
Apple strategy in the AI market
The company partnered with OpenAI in 2025 to integrate ChatGPT into products like Siri, avoiding isolated development. Diferente of Microsoft and Google, which spend billions on clouds, Apple invests in local processing to preserve user data. Essa choice has drawn criticism, but maintains high margins, with shares up 16% year to date.
In October 2025, Jony Ive sold its AI hardware startup to OpenAI for $6.4 billion, signaling external collaborations. Protótipos of AI-driven devices could emerge in two years, according to Ive and Sam Altman. Apple plans to double investments in semiconductors for AI by 2027.
Rivals such as Meta and Amazon lead in adoption of generative models, with usage rates above 40% in apps. Apple, with a 30% market share in smartphones, is betting on customer loyalty to drive updates. Analistas predict that the new Siri, scheduled for iOS 19, will increase engagement by 25%.
Recent challenges in artificial intelligence
The Apple Intelligence, launched in 2024, promised parity with leaders, but delays frustrated expectations. Recursos as notification summaries were disabled due to errors, and the enhanced Siri postponed to 2026. Críticos points to a lack of communication between AI and marketing teams, with misaligned budgets.
In 2025, the company canceled the autonomous car project to reallocate engineers to AI, but the exodus of talent persisted. Relatórios indicates 40 hires by OpenAI of directors from Apple in November. Apesar Additionally, Cook describes AI as “deep technology” with a focus on personalized experiences.
The reorganization seeks to correct dysfunctions, with Subramanya bringing expertise in assistants like Gemini. Apple increased spending by 50% for AI in 2025, totaling $10 billion, but prioritizes efficiency over massive scale.
Partnerships and vision for the future
Integration with Gemini from Google occurs via API, with initial payments to the partner. Essa approach allows access to broad knowledge without extensive own infrastructure. In 2026, updates to Siri will include agentive commerce, boosting service revenues by 15%.
The sale of Ive startup to OpenAI opens doors to innovative hardware like AI glasses. Projetos in domestic robotics have been relocated but persist under new leadership. The Apple targets 80% on-device processing in future models, reducing latency.
Executives emphasize user confidence, with internal tests showing 90% accuracy in everyday tasks. Giannandrea’s transition to consultant ensures continuity, while Subramanya drives acceleration.
