Meta built a program to watch how its own employees use their computers. Mouse movements, clicks, keystrokes, occasional screen snapshots. The goal was to feed that behavioral data into AI model training. Then, in late June, something went wrong.
Meta has paused its Model Capability Initiative, known internally as MCI, following a security incident that exposed sensitive employee data to broader internal access than intended. The program, which launched in April 2026, was suspended on June 22, 2026, while the company investigates how the exposure occurred.
To be clear about what this program actually was: Meta was logging the moment-to-moment computer behavior of US-based employees, not to monitor productivity in the traditional sense, but to generate training data for its AI models.
What happened on June 22
The incident that triggered the pause involved sensitive employee data becoming inadvertently accessible across the company. Meta’s own investigation found no evidence of external breaches or unauthorized access by outside parties.
