Meta restricts internal use of Claude Code and Codex over distillation

Meta Platforms has restricted engineers in its Applied AI division from using Anthropic's "Claude Code" and OpenAI's "Codex," according to reporting based on internal documents. The stated reason is concern over "distillation" — the risk that outputs from these rival tools could seep into Meta's own AI training data and transfer competitors' capabilities into Meta's models.[](https://www.firstpost.com/tech/meta-limits-employee-access-to-claude-code-and-codex-amid-distillation-concerns-14027551.html)
