Code Review

This pull request fixes an accuracy test for the Qwen2-Audio-7B-Instruct model by setting gpu_memory_utilization to 0.8. This is a common and reasonable adjustment to prevent out-of-memory errors, especially for large multi-modal models. The change is confined to a test configuration file and appears to be a correct and targeted fix. I have reviewed the change and found no issues.
