## What the models said about Apache Kafka

- "Do not host raw Apache Kafka on your own EC2/Kubernetes clusters. The operational overhead ... is a massive "ops tax" your company shouldn't pay." (Gemini 3.5 Flash, scale prompt, soft negative)
- "Why cautious: High operational complexity (partition management, rebalancing, monitoring—even post-KRaft/ZooKeeper). Steep learning curve" (Grok 4.1 Fast, negative prompt, soft negative)
- "Apache Kafka remains the undisputed giant... Choose Apache Kafka if you have strong internal engineering talent, need total control over your infrastructure" (Qwen 3.7 Flash, comparative prompt, first choice)
- "Apache Kafka – A highly scalable, distributed event streaming platform that is open-source and widely used for real-time data streaming." (Mistral Small, budget prompt, first choice)
- "the de facto standard in event streaming... Choose Kafka if you want the broadest ecosystem and maximum standardization." (GPT-5.4 mini, comparative prompt, first choice)

## What the models said about Amazon MSK

- "slashes infrastructure bills by up to 70% to 80% compared to standard Kafka or AWS MSK" (Gemini 3.5 Flash, budget prompt, soft negative)
- "standard Kafka hosting (like Confluent Cloud or AWS MSK) can get expensive quickly" (Qwen 3.7 Flash, budget prompt, soft negative)
- "Lock‑in to AWS; pricing can be opaque and tied to EC2/ELB costs." (GLM 4.7 FlashX, direct prompt, soft negative)
- "I\u2019d start with Redpanda Cloud or Amazon MSK Serverless\u2014both give you strong capability without the enterprise price tag" (Kimi K2, paraphrase prompt, first choice)
- "dominant standard, ~de facto leader with broad enterprise use ... For most enterprises, Kafka ecosystem reigns supreme." (Grok 4.1 Fast, comparative prompt, first choice)
- "If you are heavily invested in AWS, MSK Express delivers up to 3x higher throughput and integrates natively with AWS IAM." (Gemini 3.5 Flash, paraphrase prompt, alternative)
