Now as you can see from the article, it starts turning. People are getting less pricey than agents on API pricing.
Copilot switches to API pricing starting next month (let's see how long it will last for our $39, and $19 since September), Anthropic switches all corps into API based pricing. From the most popular choices I think only Codex didn't switch yet (although it is hard to tell because I don't know their enterprise pricing).
