I won't argue with your point; both Anthropic and OpenAI name their models poorly, and it is hard to follow unless you're already following it.
"Sonnet" only makes sense relative to other things but not by itself. If you don't know those other things, it is difficult to understand.
But, if you were asking (and I'm not sure that you are): "Sonnet 4.6 is a cheaper, but worse, version of Opus 4.6 which itself is like GPT-5.3 Codex with Thinking High. Making Sonnet 4.6 like a ChatGPT 5.3 Thinking Standard model."
