# Productionizing

> Use this checklist to ensure your C1 application is production-ready.

### 1. Use a stable model

Always use one of the latest stable models listed on the [Models & Pricing](/api-reference/models-and-compatibility) page. Avoid using deprecated models.

### 2. Verify model compatibility with your dependencies

Refer to the [Compatibility Matrix](/api-reference/models-and-compatibility) to confirm that your chosen model is compatible with your versions of the Crayon and GenUI SDKs. In general, if your SDK versions meet or exceed the minimum requirements listed, you are good to go. Any backwards-incompatible changes will be noted separately on that page.

### 3. Customize C1 with your brand colors and components (optional)

C1 is highly flexible and can be customized to match your brand colors and components before deployment.

<Tip>
  Learn how to customize C1 with your brand colors in the [UI Customizations](/guides/styling) guide.

  If you are using `C1Chat`, you may also want to add custom components, such as a sidebar or composer. See the [Integrating Custom Components](/guides/custom-components) guide for details.

  To add a footer with share or feedback buttons below each agent response, refer to the [Integrating a Response Footer](/guides/response-footer) guide.
