GPU support in quickstart and inquiry about repository maintenance

**Issue Description:**
I started using the quickstart guide in this repository and noticed that it's utilizing the CPU instead of the GPU. I would like to know how to configure it to use GPU acceleration.

**Additional Information:**
- I have a compatible GPU installed on my system.
- I have installed the necessary GPU drivers and libraries.

**Question:**
Is there any specific configuration or command-line option that needs to be set in order to utilize GPU resources during the quickstart process?

Also, I wanted to inquire about the maintenance status of this repository. Is it still actively maintained and supported?

Thank you.
