 The profiler is default to function across all stages. But It is highly recommended to profile specific stages by passing the stages list, preventing from producing too large trace files:
 ```python
 # Profile all stages
-omni_llm.start_profile()
+omni.start_profile()
 
 # Only profile Stage 1
-omni_llm.start_profile(stages=[1])
+omni.start_profile(stages=[1])
 ```
 
 ```python
 # Stage 0 (Thinker) and Stage 2 (Audio Decoder) for qwen omni
-omni_llm.start_profile(stages=[0, 2])
+omni.start_profile(stages=[0, 2])
 ```
 
 **Python Usage**: Wrap your generation logic with `start_profile()` and `stop_profile()`.
 
 ```python
-from vllm_omni import omni_llm
