They claim unlimited access, but in practice couldn't a user wrap an API around the app and use it for a service? Or perhaps the client effectively throttles use pretty aggressively?
Interesting to compare this $200 pricing with the recent launch of Amazon Nova, which has not-equivalent-but-impressive performance for 1/10th the cost per million tokens. (Or perhaps OpenAI "shipmas" will include a competing product in the next few days, hence Amazon released early?)
