I need Help with AI Server Guide

I want to build a home AI server using one of my PCs. It has an RTX 5080, a Core Ultra 265K, 64 GB of RAM, and 2 TB of Gen 4 M.2 storage. I have experience in web development and basic backend knowledge.

I’m planning to use Qwen3-VL, but I’m not sure which version would be better for my use case — the 4B or the 8B — considering I want fast responses but also good quality.

The idea is to upload an image to the server via HTTPS, have the AI analyze it, and then return a text description. I already tried setting this up on Debian, but I’m not sure how to properly implement it.

Is it possible to upload images to a local AI model like this? Also, could you recommend a good operating system for this kind of project and any general advice?

Finally, which programming languages and tools are typically used for something like this?
