Does API access to GPT-4 depend on reaching a minimum billed amount?

Below is some clarification on your situation:

1. Billing Setup vs. Usage Amount:
   Access to models (including GPT‑4) isn’t gated by reaching a specific billed amount. Rather, it’s tied to having entered billing information and having an approved usage limit. Even if your usage was very low last month (for example, $0.03), as long as your billing info is set up, you should have API access to the available models.

2. Model Availability:
   The latest updates (for example, the release of GPT‑4o) indicate that our flagship models are available provided you meet the billing setup requirements. There isn’t a prerequisite based on prior billed amounts to gain immediate access to GPT‑4. If your account is active with billing details, you can use the available GPT‑4 models right away.

3. No Waiting Period Required:
   Your concern about having to wait until the end-of-month isn’t applicable; access isn’t delayed by your previous billing or usage levels. Once your billing setup is complete, you’re in a tier with a preset usage limit—regardless of whether you’ve reached that limit or not. If there’s any issue with your access, the support email you sent is a good step, but generally, you should be able to start using GPT‑4 immediately.

In summary, ensure your billing information is current in your account settings, and you should have immediate access to GPT‑4 even if your prior usage was low.
