Meta is replacing human content moderators with AI at scale—reaching 90% for some content types by year-end—but employees warn the shift is too fast and removing legitimate content.

What happened

Meta has already replaced roughly half of all human moderation requests with large language models in 2025 and plans to push that share above 90 percent for some content types by the end of the year. The company switched from using Google's Gemini for moderation to its own new foundation model called Muse Spark. According to tests since March, Meta's language models make 13 percent fewer errors than humans when enforcing content policies while catching 10 percent more actual violations.

What to watch

Meta disputes the cost argument and points to quality instead, emphasizing that its tests show improved performance. The core tension is whether the company's internal quality metrics reflect what actually happens when the AI moderates at scale across diverse languages and content types.
