What other offerings? The other providers are either similarly priced for enterprises, or nonstarters for security reasons (there's very real concern in enterprises about hosted open models being modified to covertly inject security vulnerabilities, and it's not cost effective to self-host them.)

no, it works because they are the best. What other offering is there?

ChatGPT does a similar thing

My personal ChatGPT account is a Business account with 2 seats at $30/ea (minimum 2 seats required).

Why? Because for $60 you get ChatGPT Pro, significantly cheaper than the $100 normally required for the next level personal plan!

Is that some sort of legacy pricing? because on https://chatgpt.com/pricing/?type=team I see an option of either £15/ month or £75/ month, per seat, 2 seats required. So it's more expensive than a single £89/ month pro subscription.

How is 2 x 15 more expensive than 89?
