}'Kunavo vs calling Google directly
Same Nano Banana 2 weights, same responses. What a gateway changes is the account, the SDK and the bill — here is the honest side-by-side.
| Kunavo | Google direct | |
|---|---|---|
| Price (per image) | $0.0469+ (−30%) | $0.07 |
| Account | One Kunavo account, key in 2 minutes, $10 minimum top-up | A Google account plus its own billing setup |
| SDK | Keep the OpenAI SDK — change base_url, set model to "nano-banana-2" | Google's SDK, or their OpenAI-compatible layer where offered |
| Same key also reaches | Claude, GPT, image, video and audio models | Google's own catalog only |
| Billing | One Stripe balance, pay-as-you-go, never expires; failed requests unbilled | A separate invoice per provider |
| Rate limits | Shared gateway capacity, no contractual per-account limit | Google's own tier limits, raised by usage history or contract |
Go direct to Google 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.
