bindx-dev/stable_diffusion_v2_1

Stable Diffusion 2.1, BindX QNN context (SM8750)

BindX QAIRT context binaries for Snapdragon 8 Elite (SM8750, Hexagon HTP v79). Compiled with Qualcomm AI Runtime 2.50.0.260828221209. These files are a BindX conversion. They are not Qualcomm sample networks.

Original model

• Model: stabilityai/stable-diffusion-2-1
• License: CreativeML OpenRAIL++-M.
• LICENSE is the CreativeML OpenRAIL-M text. OpenRAIL++-M keeps that text and shortens paragraph 7 to: "To the maximum extent permitted by law, Licensor reserves the right to restrict (remotely or otherwise) usage of the Model in violation of this License." The Stability AI raw license URL returned 404 on 2026-11-11. The catalog page is https://github.com/Stability-AI/stablediffusion/blob/main/LICENSE-MODEL.

If you redistribute these binaries, pass on the same use restrictions and include LICENSE. You may not use the model to deliberately produce illegal or harmful content. The authors of the original model claim no rights in images you generate. You are responsible for how those images are used.

Files BindX opens

• text_encoder.bin
• unet.bin
• vae.bin
• metadata.json records the tensor shapes and quantization scales
• bindx.json

The weights are W8A16. UNet and VAE run on the Hexagon NPU, not on CPU.

Load status

The BindX loader still looks for the graph name stable_diffusion_v1_5_text_encoder inside a text-encoder context. This 2.1 binary does not use that graph name, so a curated suite does not offer this pack until that load succeeds. The files are published so the conversion is not lost.
