There are a few ways to use AI files in Photoshop. The first way is to use the AI file as a source for the background of your image. To do this, you will need to open the AI file and then select it as the background layer in your Photoshop document. Then, you will need to change the opacity of the background layer so that it is at least 50%. Finally, you will need to save your document and then open it in Photoshop again.
