SSD Latent Preview at Half-Size

The decoder provides a preview image.

Max supported resolution is between 768 and 1024px.

The model processes a latent representation that has been reshaped from 4 channels to 64 channels, which differs from the original implementation.

Inference

from diffusers import AutoencoderKL, StableDiffusionXLPipeline
from safetensors.torch import load_model
from tea_64_model import TeaDecoder

    latents = latents / pipe.vae.config.scaling_factor

    tea.to(device='cuda')
    output = tea(latents.float()) / 2.0 + 0.5
    preview = transforms.ToPILImage()(output[0].clamp(0, 1))
