Apple’s elite AI team hit hard by departures to Meta and others

Apple showed us a glossy demo of a smarter, more conversational Siri at WWDC last year. It framed “Apple Intelligence” as the company’s slow-and-steady answer to the chatbot arms race. But while product teams refined demos, something quietly more dangerous was happening: a steady trickle of the company’s small, elite foundational-models crew walking out the door — often to rivals offering eye-watering pay and the promise of faster, risk-on work. The Financial Times reports Apple has lost roughly a dozen AI staff to companies such as Meta, OpenAI, xAI and Cohere since January — a blow that cuts deep because Apple’s core foundation-models group numbers only about 50–60 people.

What looks like a personal story is actually a strategic one. Ruoming Pang, who ran Apple’s Foundational Models team, is the most visible example — decamped to Meta after being offered a package reported in the hundreds of millions. That kind of money (and the signal it sends) accelerates a feedback loop: once one senior figure leaves, recruiters say it becomes easier to poach others.

The roll call

Names matter because this is not an exodus of junior engineers. According to reporting, departures this year include Brandon McKinzie and Dian Ang Yap (to OpenAI), Liutong Zhou (Cohere), Ruoming Pang (Meta), and several others who went to Meta or to stealth startups. Many of them contributed to Apple’s research papers last year — meaning they aren’t just implementers, they helped shape the models Apple was building. For a tiny team, losing half-a-dozen senior contributors is not marginal — it’s structural.

Recruiters and AI-industry watchers describe the moment bluntly: elite model builders are strategic assets on par with IP or product units. As one recruiter told the FT, there are maybe “a thousand, maybe two thousand people in the world who have real foundational model experience,” and those people are being fiercely competed for. That scarcity explains the massive offers and why companies such as Meta are willing to spend big to assemble research power quickly.

Siri’s delay and the monolithic gamble

All this is unfolding against the backdrop of a delayed product story. Apple trotted out an ambitious, LLM-powered vision for Siri at WWDC 2024, but the full, conversational upgrade has not materialized for consumers. Internally, Apple has reportedly been rewriting Siri’s architecture entirely: teams in Zurich are said to be working on a so-called “monolithic” model — an LLM-first engine intended to replace years of accreted, hybrid systems and make Siri better at synthesis and conversation. That rewrite is complex, and losing model experts while you’re rebuilding the foundation makes the work harder and riskier.

Apple has not been silent about timing: during its recent earnings call CEO Tim Cook said the company is “making good progress on a more personalized Siri” and reiterated that the features are expected next year, while emphasizing privacy and tighter platform integration. But product timelines and talent supply runs on different clocks; investors and product rivals are already betting on the speed advantage that comes with big, concentrated recruiting pushes.

Why compensation isn’t the whole story

The headlines focus on multi-million dollar signing packages, and firms like Meta have been unusually lavish. But pay is only part of the pull. Engineers tell a consistent story across companies: a desire to work on frontier problems with fewer internal guardrails, faster iteration, and immediate access to massive compute. Apple’s culture — famously cautious, privacy-first, and product-quality obsessed — can be less appealing to researchers who want to publish rapidly, experiment boldly, and ship research at web scale. That cultural trade-off has always been part of Apple’s competitive posture; in the whirlwind of 2024–25 AI hiring, it looks like an increasingly costly one.

Options on the table

The exits force Apple into a set of imperfect choices:

Double down on hiring and compensation. Match the market and try to rebuild the bench — expensive and uncertain, given the tiny talent pool.
Buy capability. Tim Cook signaled openness to acquisitions; buying teams or startups would be a faster way to bulk up specialized expertise.
Partner or license. Reporters have said Apple is weighing using models from Anthropic or OpenAI to power parts of Siri — essentially outsourcing the hardest modeling while keeping integration and privacy work in-house. That would be a big strategic pivot for a company that prizes in-house engineering.

None of those solutions is frictionless. Buying talent is expensive and integration-heavy; partnering raises the very privacy and control trade-offs Apple markets itself on; and hiring at the Meta-level comp packages reshapes margins and incentives.

What to watch next

If you care about the product roadmap, watch two things closely: first, whether Apple announces acquisitions or major hiring blitzes aimed specifically at foundation models; and second, whether it publicly partners with a third-party LLM provider for Siri or developer APIs. Both moves would signal Apple adjusting its playbook from “we’ll build it ourselves” to a hybrid strategy that acknowledges the realities of the talent market.

For investors and the product-minded, the core question is this: can Apple preserve its unique combination of hardware, software and privacy while assembling enough model expertise to keep pace with rivals who are building faster and spending wildly? The answer will depend as much on people — hiring, culture, retention — as on chips and architectures.

A final thought

Apple’s PR and product demos show a company intent on cautious, integrated AI. But in the current sprint, where the winners are often the organizations that can move fastest and amass specialized talent, “cautious” risks translating into “behind.” The talent drain isn’t just a headline about paychecks; it’s a practical problem for an ambitious AI roadmap. If Apple wants to lead in AI on its own terms, it will need to prove it can keep and attract the small set of engineers who actually know how to build and deploy foundational models at scale — and quickly.
