During July 2025, Wutao Peng developed and integrated mixed-precision quantization kernels for the ModelTC/LightX2V repository, focusing on MXFP6 and MXFP4 formats to enhance quantization throughput and accuracy. He expanded GEMM kernel capabilities by implementing per-column bias support across multiple data types, updating epilogue operations and adding comprehensive tests to ensure correctness. Using C++, CUDA, and Python, he refactored function names for clarity and maintainability, and authored detailed documentation in both English and Chinese to lower onboarding barriers. The work demonstrated depth in performance optimization, technical writing, and kernel development, addressing both engineering challenges and user accessibility.
