Anthropic's models are fantastic, but they are -- by far -- one of the most expensive providers on an API basis. That's a large part of what makes the Max plans a great deal, right now.

All it takes is another provider to land a combination of model and cost that makes Code less of a deal for vendor lock-in to become a problem.
