 ## Use of generative AI
 
-We generally discourage PRs entirely generated by an LLM. For any part generated by an LLM, please put extra effort into your self-review. By using generative AI without proper self-review, the time you save ends up being more work we need to put in for proper reviews and code cleanup. Please keep that in mind when submitting code by an LLM. Clearly state the use of LLMs/(generative) AI in your pull request as requested by the template.
+We ask you not to open PRs generated with an LLM. We find that code generated like this tends to need a large amount of back-and-forth, which is a very inefficient use of our time. If we want LLM-generated code, it's much faster for us to use an LLM ourselves than to go through an intermediary via a pull request.
