The NLnet Labs policy page, revised 26 June 2026, restricts how large language models (LLMs) may be used in contributions to the organisation and its projects. The policy states, "We require all code and documentation contributions to be authored by a human," and requires contributors to disclose any LLM use when opening issues, vulnerability reports, or posting on the community forum. The page permits an exception for an LLM-suggested fix included with a vulnerability or bug report, and allows LLM use for linting, analysis, or review so long as the human contributor verifies and takes responsibility for the output, per the policy. The policy warns non-compliant submissions "may be closed or deleted without prior notice." Editorial analysis: This formal restriction mirrors a wider trend of infrastructure projects tightening provenance and verification requirements for LLM-assisted inputs.
