Meta is requiring its engineers to submit at least one AI-assisted code fix per week, a move designed to improve the company’s internal coding agent through real-world feedback.
The mandate fits into a much larger, more aggressive AI integration strategy at Meta. The company is targeting 65% of its engineers to write over 75% of their code using AI by the first half of 2026.
The feedback loop strategy
The company has built a system called MetaMateCR, which automates code review fixes. It has already been tested on tens of thousands of engineers internally. The weekly code fix requirement ensures that engineers are constantly interacting with, correcting, and refining the AI’s output.
The company has also piloted AI-assisted coding interviews, which began in October 2025, with a broader rollout expected sometime in 2026.
