I can only support the negative comments regarding the value of the lifetime deal, which is of course not an appsumo problem.
For us lifetime deal users, there is not much left on supermachine.

The latest quality models were removed (StableDiffusion 3.5 Large for example), higher resolution outputs were removed (Flux, Shuttle Diffusion and so on) - all without any announcement.
Last but not least the always recommended "Supermachine next Gen" is absolutely the worst I have ever seen. A blurry mess with nearly no variation between seeds and for that already criticized on Huggingface, but now even with lower resolution at supermachine.art after a few days of introduction.

So is it scam now? judge by yourself ;)
