 ### Model Optimizations
 
-This model was obtained by quantizing the weights of [phi-4]https://huggingface.co/microsoft/phi-4) to INT4 data type.
+This model was obtained by quantizing the weights of [phi-4](https://huggingface.co/microsoft/phi-4) to INT4 data type.
 This optimization reduces the number of bits per parameter from 16 to 4, reducing the disk size and GPU memory requirements by approximately 75%.
 
 Only the weights of the linear operators within transformers blocks are quantized.
