 # Improved Image Tokenizer
 
-This is an improved image tokenizer of NextStep-1,  featuring a fine-tuned decoder with a frozen encoder. The decoder refinement **improves performance** while preserving robust reconstruction quality. We **recommend using this Image Tokenizer** for optimal results with NextStep-1 models.
