I am not able to use the tokens provided by a Claude Max account either.
But if someone tries to be clever and have 10 employees use a single Max account, they probably run into the limits often. And if the response is to let them just buy API-prized tokens instead of getting more accounts, that gets very expensive very fast. The single-user accounts are subsidized. The extra token prices are not.
Actual business accounts are prohibitively expensive. And at least Anthropic terminates subsidized accounts when they see extensive use.

Real token prices are insane. Most businesses couldn’t afford them. And eventually the VC capital will dry up. The cheap AI bubble will burst. And then the market is in for a real sticker shock.
Better be prepared to switch to local inference for as many use cases as possible.
