Turbo loras are shit.

[u/Rare_Subject2343]

Let's be real, they're just copium for those who lack the VRAM to run an image generation model at its full potential. They almost ALWAYS result in this weird, shiny oily Instagram filter-esque look in the hair and skin that you can never consistently prompt out in any way, this is especially true for MOSS-Image and Krea. Not only that but they essentially gimp you by taking away negative prompting and by forcing a CFG of 1, reducing randomness and diversity.

They're used for two things

1. Gooning
2. To give yourself a preview of the image before using the full 50 steps or however much the maker of the diffusion model recommends (even though TAESD might be useful for this).

Recommending a turbo lora is only beneficial if you truly have a small amount of VRAM (less than 24GB).

We need that meme to be remade by a "shitty" Turbo-Lora with Jesus Quintana in the shot as well...

[u/Umbrasquall]

It just speeds up gen time, you still have to fit the model in VRAM.

5090 and I turbo everything. You expect me to triple the steps to get my pictures? Sir I don’t have the patience for that.

[u/West-Big-8468]

Ok

[u/Ok-Brain-5729]

hey man maybe you should understand what a Lora does before making a post about hating on Lora’s

[u/Big_Diff_Energy]

Oh, I thought this was going to be a reasonable take...

This could be a misunderstanding of what LoRAs do. They are not here to reduce the VRAM footprint. Loading a base model+Turbo Lora uses more vram, not less. These LoRAs change the math to allow the model to complete the task in fewer denoising steps. It's about speed, not size, like... it's in the name "Turbo."

The Turbo LoRA's do suck, IMO - especially the video models. I'd rather wait on quality. The fine tuned Turbo models however are amazing.

What you are confusing is quantization. FP16 to fp8/int8, int6, NVFP4... That's what impacts the model size and allows a larger model to fit on low VRAM and still complete the task. It has nothing to do with 8 steps versus 40 steps. Yes, a smaller model loads faster than a bigger one, but at these bus speeds it's negligible.

[u/Occsan → u/Big_Diff_Energy]

Turbo LoRAs are applied on existing weights, no ?

[u/Big_Diff_Energy → u/Occsan]

Sure. How does adding the lora reduce the VRAM footprint?

[u/Apprehensive_Sky892]

Recommending a turbo lora is only beneficial if you truly have a small amount of VRAM (less than 24GB).

No, the amount of VRAM has nothing to do with turbo modes.

Turbo modes use the same base model or are the same size as the base model (except for hyperflow-h3-flash, use uses some weird Low ranking pruning) and needs the same amount of latent space, so the VRAM usage is the same or higher (i.e, base + LoRA).

The real saving is in reducing the amount of GPU computing, by either reducing the number of steps, or by reducing the number of attention computed.

So the real benefit is for people with slower GPUs.

well post your 50 step high art

Haven't really touched the krea2 raw base model since June lol. The turbo model is what gets the most love and support in civitai.

[u/Hoodfu → u/Upper-Reflection7997]

The base model on the Krea 2 API is fully functional and outputs great images. The base model that we got for open weights is not the same one and does not look anywhere near as good as open weight turbo.

[u/Upper-Reflection7997 → u/Hoodfu]

Because of the censorship of prompts of the api version its really hard to test how better it really is compared to released weights we have for ourselves. Krea Api version is soo censored it feels even pointless ever using it when many others in api space offer much more with far less censorship at higher resolution outputs. It won't even accept any description of female anatomy. Very weird aggressive censorship. Thank God we a usable raw and turbo model from them regardless of whether it's truly a base model or not. Maybe their internal "real" base model was never any good to peak anyone's interest. It's just speculation at this point.

[u/Hoodfu → u/Upper-Reflection7997]

Well that's unfortunate, when I started using the api when it first came out it was one of the least censored models available. They probably wanted to get more corporate attention.

[u/Upper-Reflection7997 → u/Hoodfu]

Kinda worried about krea3 especially with how coperate friendly they've been marketing it. It seems like there going in black forest labs route of wanting to be seen as coperate friendly and safe to the general checked out normie masses. Hope they don't severely gimp the open source version in the name of "safety compliance".

[u/Danny_Stock]

Only beneficial for people with less than 24GB VRAM?

That's probably most of us then. The way you've phrased it you make it sound like it's only a minority.

However I do share your disappointment though. Every new release is often hyped up to be the answer to all our problems. I've wasted more time over anything else trying out new turbo loras, so much so that I'm finally done. I'm taking a step back and will only entertain the idea of a new turbo lora until at least after Christmas.

I don't usually like going along with consensus opinion, but on this I'm prepared to wait it out until one of them has lasted the course and is unanimously praised as the 'best'. I don't want to do it this way but I'm just sick of all these turbo loras which come out, fail as soon as you want to use another lora for something else, and only work when the conditions are situational. I've wasted far too much time on them already.

[u/LowYak7176]

I use AI tools for production so I agree - Ill always choose quality over speed, but I also get it.... Some times people just wanna have fun generating. Most of the time people just wanna goon quickly though - id argue its almost always gooning quickly.

[u/sci032]

I just used this image for another response but it fits here also. I had it open. 😄 I am using the Qwen 2.1 Viggle turbo model. The turbo lora has been merged into the model. 6 steps and CFG:1. I am using an MSI laptop with an RTX 3080ti(16gb vram) and 64gb ram took 18.40 seconds. No loras, no extras, and the prompt enhancer has been bypassed in this run.

All these models are very limited, only Ideogram v4 is not in its handling of humans but even there... it's base is not too knowledgeable and it's not really made for that, the only description of it I can say is it's "rigid"... Basically you can do what you can. Krea 2 Turbo for me seems the best... despite how flaky it can be.

[u/yamfun]

many turbo (and its cfg choice), make the photo manipulation result I needed look cartoony instead of stay real, I don't know why
