+Alternatively, we can use a two-stage pipeline as follows: 
 First, the base model is used to generate latents of the desired output size. 
 In the second step, we use a specialized high-resolution model and apply a technique called SDEdit (https://arxiv.org/abs/2108.01073, also known as "img2img") 
-to the latents generated in the first step, using the same prompt. Note that this technique is slightly slower than the first one, as it requires more function evaluations.

 ### Model Description
 
 - **Developed by:** Stability AI
 - **Model type:** Diffusion-based text-to-image generative model
-- **License:** [OpenRAIL-M CreativeML](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/blob/main/LICENSE.md)
+- **License:** [CreativeML Open RAIL++-M License](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/blob/main/LICENSE.md)
 - **Model Description:** This is a model that can be used to generate and modify images based on text prompts. It is a [Latent Diffusion Model](https://arxiv.org/abs/2112.10752) that uses two fixed, pretrained text encoders ([OpenCLIP-ViT/G](https://github.com/mlfoundations/open_clip) and [CLIP-ViT/L](https://github.com/openai/CLIP/tree/main)).
