- **[Add a Foundation Model](https://help.salesforce.com/s/articleView?id=data.c360_a_ai_foundation_models_create.htm&release=264.0.0&type=5)**  
    Adding a foundation model in AI Models (formerly Einstein Studio) establishes an endpoint connection between the external model provider and Salesforce. After you connect the model, create a new model configuration and evaluate your model’s response to custom prompts.
- **[Edit or Delete a Foundation Model](https://help.salesforce.com/s/articleView?id=data.c360_a_ai_foundation_models_edit_delete.htm&release=264.0.0&type=5)**  
    You can edit most of your foundation model settings as long as the model isn’t a source for other models. If it’s used as a source, you must first delete all associated model configurations. You can delete a foundation model if it’s no longer needed.
- **[Monitor Model Activity](https://help.salesforce.com/s/articleView?id=data.c360_a_ai_foundation_models_configured_monitor.htm&release=264.0.0&type=5)**  
    View your model inference use and errors in a dashboard. Use important indicators to help you track, adjust, and improve model performance.
