Async GRPO with LoRA Across HF Jobs Without NCCL

Summary

Hugging Face's article presents an approach for running asynchronous Group Relative Policy Optimization (GRPO) with LoRA across HF Jobs. Its stated design uses a bucket and a proxy while avoiding NCCL, although the extract provides no implementation steps, measurements, or comparisons. The page metadata also lists deepseek-ai/DeepSeek-R1-Distill-Qwen-1.5B as a 2B-parameter text-generation model updated on February 24, 2025.
