Simple Diffusion XS (sdxs-2b alpha version)

XS Size, Excess Quality

Train status: 4xRTX5090 / we need more gold / support us please..

At AiArtLab, we strive to create a free, compact and fast model that can be trained on consumer graphics cards.

  • CosmosTransformer3D: 2b parameters
  • Qwen3.5: 0.8b parameters
  • Qwen vae: 16ch8x
  • Resolution: Default 768x1152, trained from 576 to 1152 with step 64
  • Limitations: trained on small datasets ~2.5kk, focused on art / illustrations / anime and photo
  • Captions: danbooru, natural (short/medium), trained with 250 max toks

Key points

  • Apr 2026: Started research of Cosmos Transformer
  • May 2026: 1st preview (Initial model weights)
  • May 2026: finetuned Qwen3.5-0.8B
  • May 2026: hybrid EDM/Karras scheduler
  • May 2026: img2img pipeline and txt2video pipeline (not trained)
  • May 2026: telegram bot
