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 balance and a lower per-token rate across every provider.
