 ### Run the quantized model
 
 ```bash
 # start inference on a gguf model
-./main -m ./models/mymodel/ggml-model-q4_0.gguf -n 128
+./main -m ./models/mymodel/ggml-model-Q4_K_M.gguf -n 128
 ```
 
 When running the larger models, make sure you have enough disk space to store all the intermediate files.
