It didn't click for me. I haven't used those words since grade school. In addition, references will often only cite one model. For example, the title here used "Opus" which to a layman would mean absolutely nothing. If this title was "Claude 3 Pro has stunned AI researchers...", it's becomes much clearer to me. I'm sure the marketing person who presented this idea to the execs had slides showing explaining what an Opus, Sonnet, and a Haiku meant and everyone thought it was a good idea. But even if a small percentage of people don't understand the naming scheme, it has already failed.
