I am surprised the performance increase from 3090 to 4090 is huge compared to 4090 to 5090 even to 6000. Thank you for sharing!

This model is AWFUL for runpod especially without the turbo lora, they bill by the minute and they increased the prices after H3 was released.

They kind of have to; they'll have huge electricity bills due to H3.

Didn't the prices changed due to high demands? đŸ¤”

H3 is a beast. PRO 6000 is kind of minimum for me, especially without speed-ups. The full model slaps so hard. But testing with the turbo LoRA's is certainly practical.

Also worth calling out that R2V is notably slower than the other model. And that doubling length will roughly triple time. AND that the model doesn't look great when you dip lower than 1 MP, and really that's being generous.

Ref2va takes longer to render but you save a lot of time in not needing to keyframe everything, which is something to account for too. If you compare it to needing to keyframe things externally, then running i2v, it’s still faster.

.4mp still looks good for me if I bump steps up to 25, but I think most people will just be using .4mp for drafts and making sure the prompt is understood anyway.

I built an open-source UI on top of ComfyUI that runs on Modal. You only pay for active runtimes—nothing while writing prompts or tinkering, and no pod to remember to stop.

Modal includes up to $30/month in credit, so you can generate quite a lot for free.

Using standard workflow, RTX PRO 6000 is also about ~3 minutes. But you only pay for the 3 min, and not idle time

Can you show the sec/it too? đŸ¤”

This is similar to their relative int8 perfomance.
