But I assume it was tested on a GTX5090 - unusably slow for my laptop.

Works just fine on my laptop, it's got a RTX5000 Ada GPU w/16GB VRAM in it.

Where should the business logic rather be? My tests are typically calling APIs to test the business logic. Trying to improve myself here.

There aren‘t any hard rules here, but you can try to build your business logic as if it was a library, where your HTTP API is merely a interface to it.
