 # Benchmark tool for transformers int4 (separate 1st token and rest)
 
-`benchmark_util.py` is used to provide a simple benchmark tool for transformer int4 model to calculate 1st token performance and the rest on CPU and GPU.
+[benchmark_util.py](https://github.com/intel-analytics/ipex-llm/tree/main/python/llm/src/ipex_llm/utils/benchmark_util.py) is used to provide a simple benchmark tool for transformer int4 model to calculate 1st token performance and the rest on CPU and GPU.
 
 ## CPU Usage
 Just put this file into your benchmark directory, and then wrap your transformer int4 model with `BenchmarkWrapper` (`model = BenchmarkWrapper(model)`).
