I wrote a similar post about a week ago, but for an [unsupported] Radeon RX 5500 with 4Gi RAM with ollama and fedora 41. Can only run llama:3.2 or deepseek-r1:1.5b, but they're pretty usable if you're ok with a small model and it's for personal use.

I didn't go into detail about how to setup openweb-ui, but there is documentation for the on the project's site.
