Zuckerberg Moves His Desk Into Meta's AI Lab and Starts Coding Again

The CEO Returns to Code

Mark Zuckerberg has made a striking symbolic and practical move: he has physically relocated his desk into Meta's Superintelligence Labs, the company's most important AI division. Meta President Dina Powell McCormick revealed the news at the Semafor World Economy Summit in Washington, D.C., noting that Zuckerberg is "coding all day long" alongside the unit's leaders.

According to the Financial Times, Zuckerberg has been dedicating 5 to 10 hours each week to hands-on coding on various AI projects, an unusual level of technical involvement for the CEO of a company valued at over $1.5 trillion.

Inside Superintelligence Labs

Zuckerberg now sits alongside Alexandr Wang, Meta's chief AI officer and former CEO of Scale AI, and Nat Friedman, the former GitHub CEO who serves as vice president of product and applied research. The pair were recruited last year as part of a sweeping reorganisation of Meta's AI efforts, which included a $14.3 billion investment in Scale AI.

Meta Superintelligence Labs comprises four groups covering large language models, fundamental research (FAIR), consumer products, and AI infrastructure.

Muse Spark Changes the Game

The hands-on leadership shift comes just days after MSL released its first model, Muse Spark, on 8 April. The natively multimodal reasoning model, codenamed Avocado and built over nine months, represents a significant upgrade over Meta's previous Llama models. Notably, Muse Spark is proprietary, marking a sharp departure from Meta's long-standing open-source strategy.

The model features a novel Contemplating mode that orchestrates multiple reasoning agents in parallel. Meta's stock rose 6.5% on the day of the announcement.

The Bigger Picture

Zuckerberg's move reflects a broader transformation at Meta. Internal documents have shown that some engineering teams are mandated to have 65-80% of their committed code written by AI by mid-2026. Meanwhile, Meta is also developing a photorealistic AI avatar of Zuckerberg that employees can interact with in real time.

McCormick has argued that the United States will need "a whole new workforce," including half a million electricians, within two years to build the infrastructure AI demands. Whether Zuckerberg's coding sessions yield breakthroughs or serve as a signal of priorities, they leave no doubt about where Meta is placing its bets.
