Meta will lay off approximately 600 employees within its artificial intelligence division as part of efforts to streamline operations and reduce management layers, a spokesperson confirmed to CNBC on Wednesday.

The cuts were detailed in a memo from Chief AI Officer Alexandr Wang, who joined in June as part of Meta’s $14.3 billion investment in Scale AI. Affected roles span Meta’s AI infrastructure units, the Fundamental Artificial Intelligence Research (FAIR) unit, and other product-related positions.

Employees within TBD Labs, which includes many of Meta’s top-tier AI hires brought in over the summer, will not be affected, according to sources. The move highlights CEO Mark Zuckerberg’s strategic focus on retaining high-cost, high-potential talent over legacy staff.
