And it scales up - the $200 plan gets you something like 20x what the Pro plan gets you. I've never come close to hitting that limit.

It's obviously capital-subsidized and so I have zero expectation of that lasting, but it's pretty anti-competitive to Cursor and others that rely on API keys.

Ignoring the training costs, the marginal cost for inference is pretty low for providers. They are estimated to break even or better with their $20/month subscriptions.

That being said, they can't stop launching new models, so training is not a one time task. Therefore one might argue that it is part of the marginal cost.
