Kunavo vs calling ByteDance directly

Same Seedance 2.5 weights, same responses. What a gateway changes is the account, the SDK and the bill — here is the honest side-by-side.

KunavoByteDance direct
AccountOne Kunavo account, key in 2 minutes, $10 minimum top-upA ByteDance account plus its own billing setup
SDKKeep the OpenAI SDK — change base_url, set model to "seedance-2-5"ByteDance's SDK, or their OpenAI-compatible layer where offered
Same key also reachesClaude, Gemini, GPT, image, video and audio modelsByteDance's own catalog only
BillingOne Stripe balance, pay-as-you-go, never expires; failed requests unbilledA separate invoice per provider
Rate limitsShared gateway capacity, no contractual per-account limitByteDance's own tier limits, raised by usage history or contract

Go direct to ByteDance 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 and one bill across every provider, without opening a separate account with each one.
