is a recent sampler now we have developed with the goal of improving overall coherency and quality, especially at higher resolutions. Based on the Euler ancestral sampler, we create a recent sine-based schedule that interpolates between multiple passes of the regular diffusion model as sampling progresses. This approach ensures that SD attends to each local and global features. Oftentimes when sampling at higher resolutions with the traditional samplers, SD can produce repeats of the identical subjects or bizarre anatomy, this is basically resulting from poor global attention at higher resolutions, and smea goals to resolve that.

nai_smea & nai_smea_dyn are perfect for higher resolutions!

The differences between the 2 recent samplers are most blatant when higher image resolutions are used. nai_smea_dyn focuses less time on lower generations and begins to shine dynamically within the mid to high range of a generation. We’ve noticed barely more refined compositions. Ultimately, the effectiveness of every sampler will depend upon the particular use case and image resolution.

Nai_smea runs multiple passes of the unet during each step, it costs barely greater than the opposite samplers based on the increased compute cost. The rise is relative to the increased period of time it takes the GPU to process a request.

We’ve even added a nifty choice to A for images over 1024×1024 and above pixels. You possibly can toggle this setting as needed — so you continue to have the choice to experiment to your heart’s content with other samplers!

The nai-smea & nai_smea_dyn sampler generations vary between the various Step and Scale counts.

The nai_smea & nai_smea_dyn sampler Scale values can go much higher before becoming unpredictable. It’s possible you’ll wish to increase the Scale value in the event you are generating at higher resolutions.

If you might have a very short prompt that seemingly performs badly please try copy-pasting it into the prompt field repeatedly. We’ve noted that this could solve issues during testing.

Sometimes the sampler may deal with different features of your prompt that differ from the previous defaults:
You possibly can alleviate this with emphasis and de-emphasizing features of your prompt.

Get able to see your world in stunning detail, and let your imagination run wild with the limitless possibilities of nai_smea and better resolutions!
We are able to’t wait to see what recent masterpieces you create.
