Before you start

What is SU8?

SU8 lets you call OpenAI, Claude, Gemini, and other models with one API key. Pricing is public, billing supports packages and pay-as-you-go, and the console keeps each call easy to review.

Which models and providers are supported?

SU8 currently covers mainstream modern models from OpenAI, Anthropic, Google, Mistral, Alibaba, ByteDance, and more. The model page shows the current catalog.

How does billing work?

Packages are better for steady usage. Pay-as-you-go balance is better for trials or bursts. Both can coexist on the same account.

Is it compatible with OpenAI SDKs?

Yes. Point the OpenAI SDK base_url to SU8 and reuse your existing Chat Completions code. Additional protocol adapters are being expanded.

Does the console show usage?

Yes. The console includes request logs, token usage, cost analysis, key management, package quota, and per-key troubleshooting.
