## What the models said about Redis

- "Redis is extremely fast but should be used with caution for data that needs to persist on disk or for applications requiring complex queries" (Mistral Small, negative prompt, soft negative)
- "Cautious when: Using it as a primary database rather than a cache — it's an in-memory store, and data durability can be a concern." (DeepSeek V4 Flash, negative prompt, soft negative)
- "early versions lacked auth. Redis 7+ is solid; use ACLs and avoid as a primary durable store unless clustered with persistence." (Grok 4.1 Fast, negative prompt, soft negative)
- "Redis is the most popular and versatile key-value store... ideal for mid-sized B2B applications" (Mistral Small, paraphrase prompt, first choice)
- "Redis receiving the highest rating of 8.9 among the leaders" (Claude Haiku 4.5, comparative prompt, first choice)
- "Key-Value Stores
Top Examples: Redis, Amazon DynamoDB" (Qwen 3.7 Flash, comparative prompt, first choice)

## What the models said about Google Cloud Firestore

- "If you do not have IT staff and just want to launch an MVP quickly, start with Firebase (Firestore)" (Qwen 3.7 Flash, budget prompt, first choice)
- "For a managed cloud option, Azure Cosmos DB, Amazon DynamoDB, or Google Cloud Firestore are all common consumption-based choices." (Perplexity Sonar, paraphrase prompt, alternative)
- "Cloud Firestore has a free quota, including 1 GiB of stored data, 50,000 reads/day" (GPT-6 Luna, budget prompt, alternative)

Share is the count of first choices across the direct, paraphrase, budget and scale prompts over all fourteen models, for a mid-market B2B company; rank is within the category.
