## What the models said about KeyCDN

- "KeyCDN has a smaller network and less global coverage compared to larger CDN providers" (Claude Haiku 4.5, negative prompt, soft negative)
- "No-SLA/consumer tiers (Bunny.net, KeyCDN): Avoid for critical/production systems" (Grok 4.1 Fast, negative prompt, soft negative)
- "small providers — While some are decent, small CDNs often lack" (DeepSeek V4 Flash, negative prompt, soft negative)
- "KeyCDN is another popular choice, offering transparent pricing ... a good fit for mid-market B2B organizations" (Mistral Small, direct prompt, first choice)

- "I'd suggest starting with Bunny.net or KeyCDN for cost-effectiveness" (MiniMax M2.5, direct prompt, first choice)

## What the models said about Amazon CloudFront

- "It's best to avoid unless you have strict cost controls and predictable traffic patterns." (Mistral Small, negative prompt, hard negative)

- "Lambda@Edge is generally slower and more expensive to execute than Cloudflare Workers or Fastly's Compute@Edge, and AWS data transfer pricing can become complex and costly at scale" (Claude Haiku 4.5, comparative prompt, soft negative)
