The QGIS open-source project has formally banned AI-assisted contributions as of September 24, 2026. The new policy, documented in QGIS Enhancement Proposal 428, explicitly prohibits any code or content generated with AI tools. The decision was confirmed on the project's GitHub repository and followed a developer mailing list discussion earlier that month.
The policy change was proposed and merged by contributor nyalldawson, who emphasized the need for clear guidelines on AI use within the project. The proposal received 38 positive reactions and was debated among core developers and contributors on the QGIS developer mailing list. The discussion highlighted concerns about code quality, maintainability, and the integrity of contributions generated by AI.
This move by QGIS reflects a broader trend among open-source projects grappling with the implications of AI-generated code. While some communities encourage AI tools to accelerate development, QGIS’s strict ban underscores caution about relying on AI for critical geospatial software. The policy aims to preserve human oversight and accountability in the project’s codebase, setting it apart from other projects that have adopted more permissive AI policies.
The updated AI policy is now officially part of QGIS’s contribution guidelines, accessible on their GitHub repository. The project’s next major release cycle will operate under this new rule, affecting all contributors worldwide. The QGIS community continues to monitor AI’s impact on open-source development through ongoing discussions on their developer mailing list.
