FAQ

1. Which API endpoint should I use?

• Standard API: https://api.letai.run/v1
• CN2 accelerated API: https://cn-api.letai.run/v1
• Website: https://api.letai.run/

Use the standard endpoint by default. If you are in Mainland China and routing is unstable, try the CN2 endpoint.

2. What is different from the official OpenAI endpoint?

In most clients, you only need to replace Base URL and API key:

• Official: https://api.openai.com/v1
• Let AI Run: https://api.letai.run/v1

The request shape (for example /chat/completions) stays compatible.

3. How can I verify my setup?

Send a minimal curl request. If the response includes choices and model output, your setup is usually correct.
