Meta Demands Engineers Write 75% of Code With AI

Meta has set concrete targets for how much of its engineers' code should be written with AI tools. Some teams are expected to reach over 75 percent AI-assisted code by the first half of 2026.

Internal documents reviewed by Business Insider reveal that targets vary by division. Meta's creation org, the team behind Messenger, WhatsApp, and Facebook, has set a first-half 2026 goal requiring 65 percent of engineers to write more than 75 percent of their committed code using AI coding tools. The Scalable Machine Learning team had a February target of 50 to 80 percent AI-assisted code.

A company-wide Q4 2025 goal called for 55 percent of all code changes to be AI-generated.

The tools being used include Meta's own Metamate and Google Gemini. The company has also restructured parts of Reality Labs into small AI "pods" with new job titles.

The push comes alongside layoffs affecting hundreds of employees this week across multiple divisions, including Reality Labs, recruitment, and other departments. CEO Mark Zuckerberg has repeatedly stated that AI enables smaller, highly talented teams to accomplish what previously required large workforces.

For CIOs and technology leaders, this sends a clear signal: AI-assisted coding is no longer experimental. It has become a KPI.
