## What the models said about GitHub Advanced Security

- "GHAS is sold as an add-on license that can be quite expensive for a mid-sized B2B budget." (Gemini 3.5 Flash, paraphrase prompt, soft negative)
- "Top Recommendation: GitHub Advanced Security (GHAS)" (Kimi K2, paraphrase prompt, first choice)
- "GitHub Advanced Security / CodeQL if your company is deeply GitHub-native and wants SAST in the same platform." (Muse Glimmer 30B, comparative prompt, alternative)
