PROFILE
Sun Choi
Worked on the huggingface/optimum-habana repository, delivering features and fixes that advanced deep learning workflows on Gaudi hardware. Developed distributed inference and DeepSpeed integration for image-to-text pipelines, enabling multi-HPU support with BF16 and FP8 precision. Enhanced model compatibility by adding GPT-OSS architecture support and implemented the GRPO Trainer for reinforcement learning on Gaudi devices. Addressed dependency management by standardizing Python packaging and resolving AutoAWQ issues for quantized inference. Leveraged Python, Bash, and Makefile to optimize model training, inference, and performance, while ensuring robust testing and documentation updates to support scalable, production-ready deployment across diverse hardware environments.

Feb 1, 2025February 2025: Fixed critical AutoAWQ dependency issue for loading quantized models in huggingface/optimum-habana. Replaced ad-hoc pip installs with a pinned requirements.txt to lock triton, autoawq, and transformers, ensuring AutoAWQ functionality and reproducibility across environments. Addressed the dependency issue for --load_quantized_model_with_autoawq (commit 228e7b50d787057997e3da00ed79827e9b95bd36, PR #1759). Impact: more reliable quantized inference, smoother developer setup, and improved CI stability across environments.

Dec 1, 2024December 2024: Delivered a performance-oriented enhancement in the huggingface/optimum-habana workflow by enabling bf16 precision for the SDPA path in the image-to-text pipeline. This involved flag-driven optimization, documentation, and test updates to ensure reliable behavior and ease of use. The change improves throughput by allowing PyTorch to use bf16 for SDPA operations while keeping the overall workflow compatible with existing configurations.
