How does ChatGPT code security compare to GitHub Copilot?

Both ChatGPT and GitHub Copilot generate code with security vulnerabilities, but they differ in context awareness. Copilot has access to your project files and can generate code that better fits your existing patterns, while ChatGPT works from isolated prompts without project context. However, Copilot can also propagate insecure patterns already present in your codebase. Research indicates both tools produce vulnerable code at similar rates, with neither consistently outperforming the other on security metrics. Regardless of which AI tool generated the code, UNPWNED can scan the resulting application to identify security weaknesses.
