AWS charges $32/hr for an 8xA100s (p4d.24xlarge) which comes out to $4/hour/gpu. Yes you can get lower pricing with a 3 year reservation but thats not what this question is asking.

You also need 256 nodes to be colocated on the same fabric -- which AWS will do for you but only if you reserve for years.

Maybe they are using spot instances? $1/hr is about right for those.

AWS certainly isn't the cheapest for this, did they mention using AWS? Lamdba Labs is 12$/hr for 8xA100's, and there's others relatively close to this price on demand, I assume you can get a better deal if you contact them for a large project.

Replicate themselves rent out GPU time so I assume they would definitely know as that's almost certainly the core of their business.

Lambda labs charges about 11-12/hr for 8xA100.

Keep in mind that image transformer models like stable diffusion are generally smaller than language models, so they are easier to fit in wasm space. Also. you can finetune llama-7b on a 3090 for about $3 using LoRA.

Only for images. People want to generate videos next and those models will be likely GPT-sized.

lambdalabs will let you do on-demand 8xa100 @ 80GB VRAM/GPU for $12/hr, or reserved @ $10.86/hr

8xA100 @ 40gb for $8/hr

Replicate friend isn't far off.
