It's kind of hard to say this unless you go out of your way - the scaffolding for interacting with the raw model is a lot better now for many tasks. Is it that 4.7 is so much better than 4.5 or claude 1.119 is so much tuned to squeeze utility out of the LLM despite the hallucinations and lack of self awareness etc. Certainly the current products are great, but I think it's hard to separate the two things, the raw model and the agent workflow constraining the model towards utility.

You can use Claude Code with other models, so one could test that theory. https://openrouter.ai/docs/guides/coding-agents/claude-code-...
