 ## Model Card for lyraSD
 
-lyraSD is a tensorRT implementation of Stable diffusion model, with stable 1.5 weights. Main features 
+lyraSD is currently the fastest Stable Diffusion model available, boasting an inference cost of only 0.36 seconds for a 512x512 image, accelerating the process up to 10 times faster than the original version. Among its main features are:
 
-- weights: original stable diffusion 1.5 weights
+- weights: original stable diffusion 1.4 weights
 - input image: 512x512 (in img2img mode)
 - output image: 512x512
 - device requirements: Nvidia Ampere architecture (A100) or compatable
 - super-resultion: 4x by default, optional.
 
-lyraSD is a part of TME lyralab Fast Model Plan.
