Startup credits · Varies (partner path)
OpenAI for Startups (and selected VC / accelerator partners) can grant prepaid API credits that spend against the OpenAI Platform — GPT and related models billed like normal API usage. This is not ChatGPT Plus / Team / Enterprise seat billing: winning a grant does not refill ChatGPT messages. Typical path: your investor or accelerator nominates you, or you apply through openai.com/startups when the window is open; OpenAI reviews stage, product, and use case, then issues credits into the API org if approved.
