+We also provide a separate checkpoint for the custom KL autoencoder. As suggested by the Latent Diffusion paper, we found that training the autoencoder and the latent diffusion model separately improves the result. Since the official stable diffusion scripts does not support loading the other VAE, in order to run it in your script, you'll need to override state_dict for first_stage_model.
 
 The popular WebUI has the script to load separate first_stage_model parameters.
