+## Generative AI Policy
+
+Contributions written using large language models (LLMs) or other generative 'AI' programs are prohibited. LLMs produce errors so frequently and in a way that is so unlike human error that issues will regularly remain undetected and slip through, even with stringent review. This is not a worthwhile tradeoff for Reticulum, especially considering the limited time maintainers have to correct these issues, and we ask that you refrain from using any such output in your contributions.
+
+This applies to all official Reticlulm projects and documentation as well as all submitted issues and discussion in official channels, except in cases where language translation and/or speech recogntion technologies are required for communication.  We also ask that you avoid using LLMs for troubleshooting, as results can be misleading, and instead request help in one of our [various communities](https://reticulum.network/start.html).
