I really like local models for code reviews / security audits.
Even if they don't run super fast, I can let them work overnight and get comprehensive reports in the morning.
I used Qwen3.6-27B on an M5 (oq8, using omlx) and Swival (https://swival.dev) /audit command on small code bases I use for benchmarking models for security audits.
It found 8 out of 10, which is excellent for a local model, produced valid patches, and didn't report any false positives. which is even better.
