Meta has paused its AI hiring after adding 50 new employees earlier this year, aligning with a wider industry trend of reducing AI team sizes as AI tools increasingly handle coding tasks. Microsoft reports that AI now generates 20% to 30% of its code, while Amazon claims similar metrics. Amid a broader tech hiring freeze, AI job postings peaked at 16,000 in October 2024, indicating a potential shift towards optimizing existing AI capabilities over expanding teams.
