Access notes

Direct access

By Kunlun Tech, direct access in China.

Recommended path

Start from the main Tiangong AI profile and confirm whether it fits your task.

Create an API key after signup and use the Free tier first.

Run one or two real tasks before paying or switching providers.

If access is unstable, compare relay options or local alternatives.

Production decision checks

Production budget

Tiangong AI free credits are for validation. Before launch, record cost per 1K requests, retry-adjusted cost, and a monthly spend cap.

Compatibility check

If you already use the OpenAI SDK, verify Tiangong AI base URL, model names, streaming, tool calling, and JSON mode before migration.

Fallback rule

Keep one similar provider or OpenLLMAPI route ready so credit exhaustion, regional access issues, or model deprecations do not break users.
