AMD 6700XT owner here (12Gb VRAM) - Can confirm.

Once I figured out my local ROCm setup Ollama was able to run with GPU acceleration no problem. Connecting an OpenWebUI docker instance to my local Ollama server is as easy as a docker run command where you specify the OLLAMA_BASE_URL env var value. This isn't a production setup, but it works nicely for local usages like what the immediate parent is describing.
