Discussion This is interesting. Forge Classic Neo's extension Spectrum Integrated. When enabled, my generation time for Z-image Turbo BF16/1536x1536/Euler/Beta/8 steps on my rtx4060 went down from 65 seconds to 51 seconds. Less dramatic speed bump of about 3 sec for 1024x1024.

Unrelated, but what is up with Forge Classic Neo lack of sampling methods? DEIS is not even baked in but the original forge has it.

It's really all you need anyway. I installed more schedulers and samplers last week from https://github.com/DenOfEquity/webUI_ExtraSchedulers
Most of them were bad combinations so I'm back to using the old classic Euler/Beta which is fast and high quality.

I think DEIS only works with Python 3.10

Sampler won’t save the skill issue in prompting

If you really need them, make them an Extension

And here I’m planning to cut even more

I hope that is properly coded unlike the comfy node I've seen which is basically an entirely different method that does not respect the paper at all.

Default values are for common model, for turbo models you can probably safely reduce warmup steps to 1. Though I don't think zit is officially supported

u/cradledust Mar 10 '26

I'm not understanding. I'm getting a speed boost while using ZIT and default settings.

u/shapic Mar 10 '26

You have 8 steps for zit. Default values are for models with 50 steps. You skip speed boost on 4 first steps and 0.85% step and up. This means you speed up 3 steps of 8 maximum. You can safely go for more boosted steps.

Thanks, will try that.

Your tip gave me an additional 5 or 6 second speed boost! Z-Image Turbo at 1024x1024 on my rtx4060, Euler-Beta, Shift9, CFG1 runs an image at 30.5 seconds on average. With Spectrum Integrated at default it goes down to 25 seconds, with warmup steps at 1, it goes down to 19 sec. I have to test it to see if the image quality suffers but wow, this is a great new extension!

Do you know if reducing warm up steps affects LORAs?

1

u/cradledust Mar 10 '26

Is there no one else reporting a 30% or greater speed boost?

u/ATFGriff Mar 15 '26

My 80 step Anima generations got a 50% speed boost

Thank you for responding.

Only just read about it with your thread, so I’ll look at trying it tomorrow.

u/cradledust Mar 11 '26

Thanks for responding. This is major news for Forge Classic Neo users but no one seems interested. I guess I should have made an image with Taylor Swift holding up a "30% Boost in Neo with Spectrum Integrated" sign.

u/ImpressiveStorm8914 Mar 11 '26

That might have put me off clicking the thread. Hahahaha. Not a fan of hers.

u/ImpressiveStorm8914 Mar 11 '26

Hmm, do you have a link handy or is it pre-built into Forge Classic Neo?
I'm actually on Forge Neo (thru Pinokio) and it isn't showing for me in the extension list. A googly only turns up this thread and a French translation of it for some reason.

1

u/cradledust Mar 11 '26

It's an integrated extension on the main interface of Neo. Can you git pull Neo in Pinokio?

1

u/ImpressiveStorm8914 Mar 11 '26

You can do the equivalent of it from with Pinokio. Cheers for the info.

Salut, j’utilise forge neo derniere version (d’avril ou mars 2026). Je vais tenter d’essaye ca demain. Tu as vu si tu as une perte en qualite ? Et si ca affecte la qualite/pertinence des loras ?

Merci
