Worked on NVIDIA/Megatron-LM to deliver FP8 quantization and export support for TensorRT-LLM, enabling efficient model conversion and deployment in distributed and single-device environments. Extended core components in C++ and Python to handle FP8 weights and KV cache quantization, updating weight converters and adding comprehensive unit tests to validate export reliability. In a subsequent cycle, addressed a critical bug affecting key mappings during Mixtral mixture-of-experts model export, ensuring correct handling of expert layers and the MLP decoder router. This work enhanced the stability of the export pipeline, reducing deployment risk and supporting robust inference workflows for large language models.
