The correct answer is The developer who accepts a Copilot suggestion owns the resulting code and should ensure it does not infringe third party rights.

Under GitHub terms users retain ownership of the content they create in their repositories and accepting an AI suggestion is treated as authoring that code. GitHub does not claim ownership of the generated output and no automatic open source license is applied. In response to the concern the team should review suggestions before committing them, enable the public code suggestions filter to reduce verbatim matches to public code, keep or add attribution where it is required, and use code review and license compliance checks to identify problematic snippets.

GitHub owns every snippet generated by Copilot and use requires a separate license is incorrect. GitHub does not take ownership of code you write with its tools and there is no special license you must apply to use accepted suggestions.

Copilot output is open source by default and projects must follow applicable open source licenses is incorrect. Copilot does not assign an open source license to output by default and your repository’s chosen license governs your code unless a suggestion reproduces licensed material which is what review and filtering are meant to prevent.

Ownership of Copilot suggestions varies based on the specific training data that informed the model at generation time is incorrect. Ownership does not change based on the model’s training sources and the real risk is potential infringement when a suggestion closely matches protected code which is mitigated through review and duplication filtering rather than variable ownership.
