 ## Optimizations
 
+> [!TIP]
+> Optimization is dependent on hardware specs such as memory. Use this [Space](https://huggingface.co/spaces/diffusers/optimized-diffusers-code) to generate code examples that include all of Diffusers' available memory and speed optimization techniques for any model you're using.

 Modern diffusion models are very large and have billions of parameters. The iterative denoising process is also computationally intensive and slow. Diffusers provides techniques for reducing memory usage and boosting inference speed. These techniques can be combined with quantization to optimize for both memory usage and inference speed.
