🚀 Playground v2.5 1024px Aesthetic on AMD AI PC NPU

Playground v2.5 is a diffusion-based text-to-image generative model that produces highly aesthetic images at 1024×1024 resolution, as well as portrait and landscape aspect ratios. For more information, please see the Playground v2.5 blog post.

More details about this model can be found on the original Hugging Face model card: playgroundai/playground-v2.5-1024px-aesthetic.

This model repo contains the optimized ONNX models required to run the image generation pipeline for Playground v2.5 on AMD NPUs.

Model Details

The folder structure is organized to mirror the main components of the SDXL-style diffusion pipeline (scheduler, text encoders, tokenizers, UNet, and VAE decoder).

├─ scheduler/
├─ text_encoder/
├─ text_encoder_2/
├─ tokenizer/
├─ tokenizer_2/
├─ unet/
└─ vae_decoder/

The scheduler folder contains the scheduler configuration (timesteps, betas, alphas, etc.) used during the diffusion sampling process.

The text_encoder and text_encoder_2 folders contain the OpenCLIP-ViT/G and CLIP-ViT/L text encoder models used to convert the input prompt into conditioning embeddings.

The tokenizer and tokenizer_2 folders contain the tokenizer configuration and vocabulary files required to preprocess text prompts for the respective text encoders.

The unet folder contains the UNet model used in the diffusion process. The UNet is exported and structured specifically to leverage the AMD NPU accelerator for the denoising steps.

The vae_decoder folder contains the VAE decoder model used to map latent representations back to the image space. The VAE decoder is also structured to make use of the NPU accelerator for efficient image reconstruction.

Note: UNet and VAE decoder models are optimized and structured to run on AMD NPUs. The other components (text encoders, tokenizers and scheduler) are shared between GPU and NPU pipelines, but are provided here for completeness.
