 # Latent Diffusion Models
 
 Latent diffusion models use an auto-encoder to map between image space and
-latent space. The diffusion model works on the diffusion space, which makes it
+latent space. The diffusion model works on the latent space, which makes it
 a lot easier to train.
 It is based on paper
 [High-Resolution Image Synthesis with Latent Diffusion Models](https://papers.labml.ai/paper/2112.10752).
