Nine of fourteen models named Confluent Cloud first on the direct prompt; one named Apache Kafka. Both were named by all fourteen models and Confluent Cloud carries 55 labels and Apache Kafka 51, so the shares are not directly comparable.
Named in two categories this edition.
Named in three 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 streaming platforms page.
Across every category in the November 2026 Edition, Confluent Cloud and Apache Kafka were named in the same answer 102 times, of the 180 answers naming Confluent Cloud and the 163 naming Apache Kafka. In those answers Apache Kafka took the first choice eighteen times and Confluent Cloud thirty.
