CodeRabbit’s GPT-6 Cyber Scan Finds More Flaws

The real story is pipeline lift, not model mystique. The gain is meaningful, but vendor-run known-vulnerability testing should be paired with false-positive, cost, latency, and independent holdout evaluations.

• –22/33 versus 19/33 is a modest absolute recall improvement, so the severity breakdown matters more than the headline count.
• –CodeRabbit’s ensemble, codegraph, static verification, and repository context likely contribute substantially to the result.
• –Known-vulnerability detection does not prove exploitability, patch quality, or performance on novel flaws.
• –GPT-6 Cyber looks best suited as an additional high-risk review pass alongside deterministic scanners and human approval.
