I don't understand the appeal of investing in leaning and adapting your workflow to use an AI tool that is so tightly coupled to a single LLM provider, when there are other great AI tools available that are not locked to a single LLM provider. I would guess aider is the closest thing to claude code, but you can use pretty much any LLM.

The LLM field is moving so fast that what is the leading frontier model today, may not be the same tomorrow.

Pricing is another important consideration. https://aider.chat/docs/leaderboards/
