+/// Two of these names have to stand as a name part of their own. "kling" taken as a plain substring
+/// also matches the organization Klingspor, the model Inkling, and the fine-tune
+/// Llama-2-7b-chat-klingon -- all of them models to chat with, which would vanish from the user's
+/// list. The models themselves are called kling-v1 and kling-video, where the name ends at a
+/// separator. Google's veo is the same story with an even shorter word.
