Zero of fourteen models named Couchbase first on the direct prompt; zero named Redis. Both were named by all fourteen models and Couchbase carries 43 labels and Redis 55, so the shares are not directly comparable.
Named in one category this edition.
Named in four categories this edition.
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; every quote names the model and the prompt it came from. Both figures come from the nosql databases page.

“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
