Meta is laying off approximately 600 employees from its artificial intelligence unit to streamline operations and reduce redundancy. The cuts primarily affect the AI infrastructure and research teams, while key personnel in the new Superintelligence Labs remain unaffected. CEO Mark Zuckerberg's dissatisfaction with AI progress and the recent lukewarm response to the Llama 4 models have prompted these measures as the company intensifies its AI investments amid competition from rivals like OpenAI and Google.
