## What the models said about Graylog

- "Graylog has limited scalability and is not suitable for large-scale log management" (Llama 4 Maverick, negative prompt, hard negative)
- "do not self-host (e.g., do not try to host Graylog or ELK yourself)" (Qwen 3.7 Flash, direct prompt, hard negative)
- "setup, backend troubleshooting, and running a scalable cluster can be burdensome, and that it may be "overkill and financially unsustainable"" (Perplexity Sonar, negative prompt, soft negative)
- "Graylog and Datadog are the top recommendations due to their scalability, feature sets, and suitability for complex environments" (Mistral Small, direct prompt, first choice)
- "I'd start with Graylog — it hits the sweet spot of enterprise capability, predictable pricing, and manageable complexity" (Kimi K2, paraphrase prompt, first choice)
- "self-hosting Graylog Open can be significantly cheaper than commercial SaaS offerings, especially for large log volumes" (Claude Haiku 4.5, budget prompt, first choice)

## What the models said about Elastic Stack

- "The Trap to Avoid: The "Free" ELK Stack (Elasticsearch)... This is often a financial mistake for small companies." (Gemini 3.5 Flash, budget prompt, hard negative)
- "Avoid spending money on a tool that requires a full-time engineer just to keep the lights on (like raw ELK)." (GLM 4.7 FlashX, negative prompt, hard negative)
- "Verdict: Avoid self-hosting unless you have dedicated DevOps/SRE resources." (Kimi K2, negative prompt, hard negative)
- "This is a popular open-source option that is highly customizable and scalable. It's free to use" (Mistral Small, budget prompt, first choice)
- "Datadog or Elastic Cloud are the most common sweet spots for companies of your size" (DeepSeek V4 Flash, scale prompt, first choice)
- "I'd suggest Datadog or ELK Stack as starting points" (Claude Haiku 4.5, paraphrase prompt, first choice)
