Had account of Pay as you go but do not see this option now. Does this option still exist? I used it a few times last year and had a small balance but now not seeing this
Welcome to the community!
Assuming that you’re referring to API billing, then yes, API billing still exists. But the current setup is mostly handled as Prepaid Billing/API credits rather than the older “pay as you go” wording.
You can check about prepaid billing here: https://help.openai.com/en/articles/8264644-how-can-i-set-up-prepaid-billing
OpenAI’s Help Center explains that new API accounts use prepaid billing: you purchase credits upfront, API usage is deducted from those credits and you can optionally set auto-recharge.
