## Working with Global LLMs

- GUI
- API

You can view, create, edit, and delete global LLMs in the [Admin Center](https://docs.cognigy.com/ai/administer/access/admin-center/global-resources/overview) under **Resources > LLMs** as well as copy their Reference ID. To assign a global LLM to a Project, go to the global LLM page, click  or  in the **Assigned Projects** section, and select the Project. You can also view global LLMs in **Build > LLMs** and edit their settings.

You can view, create, delete, and edit global LLMs using the [Cognigy.AI API](https://api-trial.cognigy.ai/openapi#tag--LargeLanguageModels-v2.0). To do so, set the `resourceLevel` parameter to `organisation` in the JSON body.
