Meta built its own in-house Copilot
Meta just unveiled CodeCompose, an internal AI coding tool designed to rival GitHub Copilot. The largest 6.7B model is tuned on Meta’s own repositories and integrated directly into engineers' IDEs, with thousands of employees adopting suggestions at a 20%+ acceptance rate. Why it matters: Meta is prioritizing proprietary internal developer tooling over external cloud assistants, keeping its proprietary codebase strictly in-house.
