Kunavo vs calling OpenAI directly

Same GPT-Image-2 weights, same responses. What a gateway changes is the account, the SDK and the bill — here is the honest side-by-side.

Go direct to OpenAI when you need a contractual rate limit, an enterprise SLA, or a provider-only feature on day one. Use Kunavo when you want one key, one bill and a lower per-token rate across every provider.

FAQ

How much does GPT-Image-2 cost?

On Kunavo, GPT-Image-2 is $0.0633 per image — about 50% under OpenAI's official price. Failed requests are never billed, and it's pay-as-you-go — you only pay for successful calls.

Can I call GPT-Image-2 with the OpenAI SDK?

Yes. Set base_url to https://api.kunavo.com/v1, pass your Kunavo key, and set model to "gpt-image-2". Requests and responses are OpenAI-compatible.

What endpoint does GPT-Image-2 use?

GPT-Image-2 is called via POST /v1/images/generations on Kunavo's OpenAI-compatible API.

What is different from calling OpenAI directly?

The model is the same, at about 50% under OpenAI's list price. What changes is around it: one key and one Stripe balance instead of a OpenAI account with its own billing, the OpenAI SDK with base_url swapped instead of a provider-specific SDK, and the same key also reaching Claude, Gemini, GPT, image, video and audio models. The tradeoff is that gateway capacity is shared — if you need a contractual rate limit or an enterprise SLA on GPT-Image-2 specifically, go direct to OpenAI.

Is GPT-Image-2 cheaper on Kunavo?

Yes — GPT-Image-2 is about 50% under OpenAI's official list price on Kunavo, with no subscription and no minimum monthly spend. You pay per token from a $5 top-up, failed requests are never billed, and the balance never expires.
