 The following is a list of common Architecture ID values, both to serve as a reference for implementation, and as an example for other architecture IDs to be chosen by. This is not a complete list, just several examples.
 
 - **Stable Diffusion:** `stable-diffusion-v1`, `stable-diffusion-v2-512`, `stable-diffusion-v2-768-v`, `stable-diffusion-xl-v1-base`, `stable-diffusion-xl-v1-refiner`
