Presumably this is all because OpenAI offers free ChatGPT to logged out users and don't want that being abused as a free API endpoint.
Yup.
Coincidentally about an hour ago, I wanted to look something up in ChatGPT and I happened to be in a browser window I don’t normally use, with no logged in accounts. I assumed it wouldn’t work, but to my surprise with no account, no cookies of any kind it took my query and gave me an answer.
It is also intended to protect the usage patterns of pro subscribers.
As has been amply explained, the API pricing per token is far more for equivalent use when maximizing a subscription plan.
It isn’t really a massive hurdle to deal with this full SPA load check. If one is even aware it exists they already have the skills to bypass it anyway.
I get why people would “what about” the automation inherit in what OpenAI is doing but that is a separate matter.
Other businesses and applications can put into place their own hurdles and anti bot practices to protect the models they’ve leaned into—-and they have been.
Using 5.2 at 20 a month would also be a steal. Other shoe will drop on codex sooner or later
Its probably same for copilot.microsoft.com and their cloudfart usage
But do they do it whether you're logged in or not?
I noticed the ChatGPT app also checks Play Integrity on Android (because GrapheneOS snitches on apps when they do this), probably for the same reason. Claude's app doesn't, by the way, but it also requires a login.
