# Create a Custom Model
You can create a custom model (tune a new model) by adding your own data to a model and subsequently prompt the custom model in a workbook. \
\
Go to the [Models](https://lastmileai.dev/models) section on the left-hand navigation bar and click Create Custom Model to get started
Follow the steps to add your dataset, make sure to give it a recognizable name.
Once you're passed in your data, your new model will be processing for a short amount of time. Refresh the page & wait until you see that the model is "Ready" in the "My Models" tab.
Once it's ready, you can start a new workbook by clicking the dots and using "Create new workbook".
Alternatively, after you have created a custom model, you can add it to any workbook. Navigate to your workbook, click on the plus sign and select your model under Text toText models
