Best service to rent GPU and run ComfyUI and other stuff for making LORAs and image/video generation ?

I’m looking for recommendations on the best GPU rental services. Ideally, I need something that charges only for actual compute time, not for every minute the GPU is connected.

Here’s my situation: I work on two PCs, and often I’ll set up a generation task, leave it running for a while, and come back later. So if the generation itself takes 1 hour and then the GPU sits idle for another hour, I don’t want to get billed for 2 hours of usage — just the 1 hour of actual compute time.

Does anyone know of any GPU rental services that work this way? Or at least something close to that model?

Why are there no 4 step loras for Chroma?

Schnell (which Chroma is based on) is a 4 steps fast model and Flux Dev has multiple 4-8 step loras available. Wan and Qwen also have 4 step loras. The currently available flash loras for Chroma are made by one person and they are as far as I know just extractions from Chroma Flash models (although there is barely any info on this), so how come nobody else has made a faster lightning lora for Chroma?

Both the Chroma flash model and the Flash Loras barely speed up generation, as they need at least 16 steps, but work the best with 20-24 steps (or sometimes higher), which at that point is just a regular generation time. However for some reason they usually make outputs more stable and better (very good for art specifically).

So is there some kind of architectural difficulty with Chroma that makes it impossible to speed it up more? That would be weird since it is basically Flux.

@ Heavy users, professionals and others w/ a focus on consistent generation: How do you deal with the high frequency of new model releases?

* Do you test every supposedly ‘better’ model to see if it works for your purposes?
* If so, how much time do you invest in testing/evaluating?
* Or do you stick to a model and get the best out of it?

Is an RTX 5090 necessary for the newest and most advanced AI video models? Is it normal for RTX GPUs to be so expensive in Europe? If video models continue to advance, will more GB of VRAM be needed? What will happen if GPU prices continue to rise? Is AMD behind NVIDIA?

ComfyUi on new AMD GPU - today and future

Hi, I want to get more invested in AI generation and also lora training. I have some experience with comfy from work, but would like to dig deeper at home.
Since NVidia GPUs with 24GB are above my budget, I am curious about the AMD Radeon AI PRO R9700.
I know that AMD was said to be no good for comfyui. Has this changed? I read about PyTorch support and things like ROCm etc, but to be honest I don't know how that affects workflows in practical means. Does this mean that I will be able to do everything that I would be able to do with NVidia? I have no background in engineering whatsoever, so I would have a hard time finding workarounds and stuff. But is this even the case with the new GPUs from AMD?

Would be greatful for any help!

Sharing the winners of the first Arca Gidan Prize. All made with open models + most shared the workflows and LoRAs they used. Amazing to see what a solo artist can do in a week (but we'll give more time for the next edition!)

Link here. Congrats to prize recipients and all who participated! I'll share details on the next one here + on our discord if you're interested.
