I worked on a feature with GPT-4, then worked on a blog post, and now I'm proud of it. Here ya go: https://semgrep.dev/blog/2023/gpt4-and-semgrep-detailed
We put GPT-4 in Semgrep to point out false positives & fix code
Semgrep is a code search tool many use for security scanning (SAST). We added GPT-4 to our cloud service to ask which Semgrep findings matter before we notify developers, and on our internal projects, it seemed to reason well about this task. We also tried to have it automatically fix these findings, and its output is often correct.
