> Contributions must not include content generated by large language models or other probabilistic tools, including but not limited to Copilot or ChatGPT. This policy covers code, documentation, pull requests, issues, comments, and any other contributions to the Servo project.

> For now, we’re taking a cautious approach to these tools due to their effects — both unknown and observed — on project health and maintenance burden. This field is evolving quickly, so we are open to revising this policy at a later date, given proposals for particular tools that mitigate these effects.

The references to ChatGPT and Copilot suggest it was authored before the Codex and Claude Code revolution. I wonder if they'll revise it at some point soon.

Update: no, it looks like that policy document was added on a October 5th this year, so it's actually very recent: https://github.com/servo/book/commit/b80695f761798fd21c4b1f4...
