## What the models said about Radiant Security

## What the models said about SentinelOne Purple AI

- "I'm being a bit more cautious here because the comparison pages are vendor-curated and can be marketing-heavy." (GPT-5.4 mini, comparative prompt, soft negative)
- "frequently cited as the top choice for mid-market organizations because its pricing model does not scale with the number of alerts generated" (Qwen 3.7 Flash, direct prompt, first choice)
- "SentinelOne Purple AI is highly recommended for mid-market to enterprise SOCs" (Mistral Small, direct prompt, first choice)
