SenBlend 1.10版本SenBlend v1.9 (ID: 121202)

If this model seems like a clone of picXreal: blame it on convergent evolution rather than plagiarism -- one can only continuously say "no, THIS is the pinnacle of 1.5" so many times before the prophecy slowly becomes a reality. Indeed, the major difference between picXreal and SenBlend 1.9 is that the former manages to capture much deeper, richer shadows than the latter. And with that marks the final iteration of SenBlend: 1.10, because "how much better do you expect a 1.5 model to get". This adds all the new weights from picXreal on top of SenBlend with the intention of widening the variety and correcting any style problems that could be present on picXreal, a merge that is already incredibly hard to top.

With that said, I cannot prove that this model is any better, or any worse: it is an alternative in which, realistically, improvements present are so minute that they might as well be a matter of opinion. Through arduous testing, this model performed slightly better in some diffusions while picXreal performed better in others. It is for these reasons that I will no longer update this model: anything that does manage to objectively improve this model or picXreal will be so farther ahead that attempting to merge would no longer be a strategy. We have gotten that far with 1.5.

It also seems my initial prediction regarding SDXL is on the right track: we are roughly 6 months into SDXL, and we now have very promising leaps with Cascade and SD3. Another 6 months seems reasonable for a monster model that can make classic 1.5 diffusers turn their heads. We will wait and see... but for now, enjoy the latest and greatest 1.5 model.

描述:

With SDXL right around the corner, it seems that the era of 1.5 models is about to come to an end. That doesn't mean that 1.5 models will instantly be left in the dust, in fact, it will probably take a considerable amount of time before we get the same level of customization and finetuning for XL as we currently have with 1.5 models, so 1.5 models will continue to dominate until further work is done to XL, and SenBlend 1.9 represents the pinnacle of the old era of models. This is hopefully the last and best 1.5 model for realism.

SB1.9 is made up of a carefully curated mix of ZovyaV2, Reliberate, Photon, and of course, SenBlend 1.8.

Tips for Dreamboothers:

This model works bonkers for Dreambooth, much more so than previous models. I am going to share my magic formula for creating perfect dreambooths every single time. (Keep in mind that current dreambooth versions are usually broken or complete crap. You have to use an older version!):

-A1111 (not Kohya!). Get yourself an older version. Specifically, I use this commit: ea9bd9fc7409109adcd61b897abc2c8881161256

-Use this dreambooth revision: 43ae9d55531004f1dedaea7ac2443e9b16739913

-Software versions (you can see this list when you boot up A1111):

[+] bitsandbytes version 0.35.0 installed.

[+] diffusers version 0.10.2 installed.

[+] transformers version 4.25.1 installed.

[+] xformers version 0.0.16rc425 installed.

[+] torch version 1.13.1+cu117 installed. This is the most important component, do not upgrade it!

[+] torchvision version 0.14.1+cu117 installed.

Dreambooth Training Parameters (leave anything not listed at default):

-Extract EMA Weights.

-Training Steps Per Image (Epochs) = 7,360/X where X == Total Number of Subject Images. If you can spare the training time, multiply this by 3 for extra leeway.

-Batch Size: 1-8 depending on your VRAM, it is suspected (though not confirmed) that lower batch size = better quality results. Experiment and report back with your findings.

-Gradient: 1.

-Set Gradients to None: Check.

-No Gradient Checkpointing.

-Gradient Acc Steps: 1

-Class Batch Size: 1

-Learning Rate Scheduler: constant

Learning Rate = 1.5e-06 to 1.65e-06 works best! Experiment around this range and try not to deviate too much from it.

Constant/Linear Starting Factor = 0.5

Scale Position = 0.25

-Use EMA: Yes

-8bit Adam

-Mixed Precision: bf16 (if you have puny VRAM, go for fp16)

-Memory Attention: flash_attention (using xformers WILL break your model, don't say I didn't warn you!)

Happy Dreamboothing and let me know in the comments if you have questions!
