+# AI Policy
+
+Using AI (i.e., LLMs) as tools for coding is welcome. A high bar is held for
+all contributions to this project. Moreover, the project maintainers remain
+responsible for any code that is published as part of a release. Contributors
+are expected to be responsible for any code they publish.
+
+**AI should not be used to generate comments when communicating with
+maintainers**. Comments are expected to be written by humans. Comments that are
+believed to be written by AI may be hidden without notice.
+
+If you are opening an issue, you should be able to describe the problem in your
+own words.
+
+If you are opening a pull request, you are expected to be able to explain the
+proposed changes in your own words. This includes the pull request body and
+responses to questions. **Do not copy responses from the AI when replying to
+questions from maintainers.**
+
+This project requires a human in the loop who understands the work produced by
+AI. **Autonomous agents are not allowed to be used for contributing to this
+project**. Pull requests that appear in violation of this will be closed,
+perhaps without notice.
+
+If you wish to include context from an interaction with AI in your comments, it
+must be in a quote block (e.g., using `>`) and disclosed as such. It must be
+accompanied by human commentary explaining the relevance and implications of
+the context. Do not share long snippets.
+
+AI is useful when communicating as a non-native English speaker. If you are
+using AI to edit your comments for this purpose, please take the time to ensure
+it reflects your own voice and ideas. If using AI for translation, we recommend
+writing in your native language and including the AI translation in a quote
+block.
+
+This policy was adapted from [uv's AI policy].
