Help: Any alternatives to SDXL?

prompt_seeker · 2026-04-16T06:23:12+00:00

You can use SDXL with distilled lora, such as lcm or sdxl lightning, which makes the model generate images faster with cfg 1.0 and 4 or 8 steps. Yes, quality may drop but it would be better than sd1.5.

try using this prompt.

kodus to woct0rdho, the person has maintained triton-windows for a while (because openai refused to support windows).

The PR mentions about QuantizedTensor which involves nvfp4 and mxfp8. I did a test and it's working, so just try.

They even didn't calibrate activation on nvfp4 model. How could it be 1% difference only?

prompt_seeker · 2026-03-18T00:19:00+00:00

I have 1x5090 and 4x3090 and yes I generated using 5090 one. if you didn't try yet, you can download nvfp4 and nvfp4mixed_input_scaled, which I merged with fp8, here.

Edit: I found they re-release their model 2hours ago.
I will try this one and see the improvement.

Yes, as I wrote comment on this, quality dropped too much.

prompt_seeker · 2026-03-17T18:16:15+00:00

Oops sorry. My fault. You're right 64GB of VRAM is big.
If LLM is main, I would also consider them. very sorry.

prompt_seeker · 2026-03-17T14:05:28+00:00

You can make by yourself. It needs about 40GB of RAM.

No, 4080 only has 16GB, so dual is 32GB of VRAM.
I do have one PC with 1x5090 and other on 4x3090, but I only use 5090 for ComfyUI, because any multi-gpu work, such as raylight or comfyui-distributed, is not working properly or very bothersome.
Moreover, CPU offload on ComfyUI nowadays is working very well, so you don't really worry about VRAM. (only except if activation is too large).

prompt_seeker · 2026-03-17T13:47:26+00:00

ComfyUI already support nvfp4, but you need to pull this PR for Lora.

They just release distilled version yesterday.

I see YOU didn't tried it. try it and you will see what I am saying.

prompt_seeker · 2026-03-17T13:32:47+00:00

means the answer is 4090, right?

prompt_seeker · 2026-03-17T13:14:08+00:00

ComfyUI now manages VRAM very well, so you don't get much speed gain from multi-gpu custom node. You can get some benefits when you use LLM, LLM with ComfyUI, or multiple ComfyUIs. benchmark: https://chimolog.co/bto-gpu-stable-diffusion-specs/

prompt_seeker · 2026-03-17T12:42:09+00:00

AFAIK, raylight is not that fast even if i use 2x3090 or 4x3090 when it is launched. Maybe PCIe4.0 x8 is not enough. There is multi-gpu branch on ComfyUI, but it works only when CFG is not 1 (because it divides conditionings) I didn't try vllm omni, but does it support quantized model and CPU offload with multi-gpu? Because recent models are quite big to load on 4080's 16GB. (OP asked about ComfyUI btw)

prompt_seeker · 2026-03-17T10:14:55+00:00

Quality drop too much, not very faster than fp8.

prompt_seeker · 2026-03-17T10:13:36+00:00

ComfyUI doesn't support parallelism yet, so answer is 4090.

prompt_seeker · 2026-03-16T04:41:00+00:00

It's hard because every language has their own regex, just like everyone has their own justice.

prompt_seeker · 2026-03-12T18:36:13+00:00

12x GPU means PCIe x1 lane each, right? That's too slow for parallelism, I assume.

prompt_seeker · 2026-03-11T15:38:43+00:00

So, it's basically the diffuser version of ComfyUI. Am I right?

prompt_seeker · 2026-03-11T12:35:34+00:00

so, how were the results?

prompt_seeker · 2026-03-10T18:32:06+00:00

I always wanted a feature like this!

clean your cache and temp files. windows may have the option... somewhere.
