High VRAM need?

[Euchale]

I have just tried using it on a 1 Megapixel image together with Flux.Klein and it completely filled the VRAM of my 5090. Its running at 7s/it. Is this normal? I am very surprised it would be that slow despite being used together with a relatively small model.

Could you please check the VRAM you use when using Flux Klein t2i? LanPaint should take the same vram but 2-5 times slower than a normal t2i

Its completely maxed out with Lanpaint, and around 30% if I just use Flux Klein.
