Who is responsible for code that Copilot suggests once it is merged?
Why C is the answer
The developer and team who accepted it
Copilot is an assistant. People who accept code remain accountable for reviewing, testing and securing it.
In detail
- Once code is accepted and merged, it belongs to the team.
- They own its quality and its consequences.
- Apply your normal review and testing to generated code.
Use case
An illustrative scenario, not a real incident.
A bug from Copilot-generated code reaches production. The incident review treats it like any other code, because the team accepted it and merged it.

Key point: Accepting code makes it yours.
Why the other options are wrong
- A. The model provider, because its model wrote the code
- A model provider does not own your codebase.
- B. Nobody, because the code was generated automatically by a tool
- Automation does not remove accountability.
- D. GitHub, because its service generated the code in the first place
- GitHub provides a tool, and you decide what to merge.
