### Select Your AI Provider

Choose the AI model you would like to use from the list of available providers.

For most users, we recommend:

**GLM-5**

GLM-5 offers excellent performance while keeping the **cost per AI call very low**, making it a great choice for everyday trading and backtesting.

You can switch to a different AI model at any time if you wish to compare performance.
