SDXS-512-DreamShaper, fp16 ONNX for the browser
A one-step 512x512 text-to-image model for onnxruntime-web over WebGPU, exported from
IDKiro/sdxs-512-dreamshaper at commit
76f720262bb051da75666b22c902a78c8e16c763 (distilled from Lykon's DreamShaper 8; image decoder
TAESD by madebyollin, MIT). No weights were retrained or modified - only exported.
| File | Size | Graph |
|---|---|---|
text_encoder.onnx | 246 MB | CLIP ViT-L/14 text model, fp16, input_ids int64 [1,77] -> last_hidden_state float32 [1,77,768] |
unet.onnx | 632 MB | UNet, fp16 inside, float32 IO: sample [1,4,64,64], timestep [1], encoder_hidden_states [1,77,768] -> out_sample |
vae_decoder.onnx | 2.5 MB | TAESD decoder, fp16 inside: latent [1,4,64,64] -> image [1,3,512,512] in [-1,1] |
Standard ai.onnx operators only, opset 17, no external data, single files.
Sampling (one step, no guidance)
sigma = 14.614646911621094 # Euler, trailing spacing, sigma_max
x = randn(1,4,64,64) * sigma
eps = unet(x / sqrt(sigma^2 + 1), t = 999, text_encoder(clip_tokens(prompt)))
x0 = x - sigma * eps
img = vae_decoder(x0) / 2 + 0.5
Checked against the reference diffusers StableDiffusionPipeline (fp32, one step, guidance 0) on
three prompts with identical noise: PSNR 41.8 / 50.4 / 47.9 dB. In Chrome (WebGPU, Apple silicon):
~0.5-0.7 s per image after a ~5 s session build.
