I can't run GLM 4.5 on those quants, I've been unable to get beyond 96gb vram (I know you can get 112, but I'm still a linux noob)
GPT OSS 120b (60gb) loads into clear memory in 37-45s (tested 3 times), but I think it can take up to 60s if there are other models in memory. I'm not sure what's going on there, it should take ~10s to read the model from disk, but I do get a lock error in lmstudio and an alloc failure.
I don't know how to measure idle power with a model in memory (linux noob), but it's been on my desk all day with either GPT120b or Qwen Code and has been pretty quiet (just PSU fan running off and on). With Framework the fan seems to start at aroudn 55C, the system idles with a model in memory at 45-50C.
I'll try and figure out comfyui or a nice way to run image models then get back to you. They're not really something I need/use, so I'm starting from zero on how to run them.
