API credits are not a ChatGPT plan
Prepaid credits sit on the API Platform. ChatGPT subscriptions are a different product. Naming mix-ups go to ChatGPT API Credits. Official: OpenAI prepaid billing guide. Last verified: 2026-08-18.
OpenAI API Credits Explained
OpenAI credits here means OpenAI Platform / Playground prepaid API balance — not ChatGPT Plus or Pro. Use this hub for billing, limits, and GPT model unit prices.

Prepaid billing, auto-recharge, and empty balance
Add prepaid credits, optionally enable auto-recharge, and set spend limits in Platform billing. If the balance hits zero and no backup payment is enabled, API calls fail. Setup: OpenAI prepaid billing setup. Last verified: 2026-08-18.
03
Balance, usage, and limits
Check remaining prepaid credits and usage on the Platform billing and usage dashboards for the organization that owns the key — not in ChatGPT settings. Manage API Credits covers budget practice.
04
Credits, tokens, requests, and dollars
The wallet is in dollars (credits). Tokens meter the model. Requests are call volume. Convert only with that model’s official $ / 1M rates from the table below. See AI Credits vs Tokens. Free and startup paths: Free OpenAI API Credits. Expiry and refunds: only as stated on OpenAI’s billing pages the day you check — we do not invent a global rule. Last verified: 2026-08-18.
