 OpenTelemetry is an open source community, and as such, greatly encourages contributions from anyone interested in the project. With that being said, there is a certain level of expectation from contributors even after a pull request is merged, specifically pertaining to instrumentations. The OpenTelemetry Python community expects contributors to maintain a level of support and interest in the instrumentations they contribute. This is to ensure that the instrumentation does not become stale and still functions the way the original contributor intended. Some instrumentations also pertain to libraries that the current members of the community are not so familiar with, so it is necessary to rely on the expertise of the original contributing parties.
 
+### Use of AI coding assistants
+
+AI coding assistants can be valuable tools for contributors. They may help with understanding the codebase, drafting changes, writing tests and improving documentation. Contributors are welcome to use AI tools as a part of their contribution workflow. 
+
+However, contributors remain responsible for the quality and correctness of their contributions. AI generated material must be carefully reviewed, validated and adapted by the contributor before being submitted to the project.
+
+Maintainers reserve the right to close pull requests or other contributions that appear to have been primarily generated by AI with little or no meaningful review from the contributor. This includes, but is not limited to:
+
+- Opening a large number of low quality pull requests in a short period of time.
+- Submitting changes that are incomplete, incorrect, unrelated to the issue or not aligned with project conventions.
+- Posting review replies, issue comments or other responses that appear to be AI generated and/or do not meaningfully address maintainer feedback.
+- Submitting pull requests that require maintainers to spend significant time correcting or explaining basic issues that should have been caught by the contributor before submission.
+
+This policy is intended to reduce unnecessary burden on maintainers and ensure that AI tools are used responsibly in support of high quality contributions.

 ### Guidelines for native OpenTelemetry instrumentation
 
 The preferred approach to supporting instrumentation of a tool or framework is native OpenTelemetry instrumentation. Compared to adding a new instrumentation library to this community repository, native instrumentation is better for:
