This skill facilitates training and fine-tuning language models using Transformer Reinforcement Learning (TRL) on Hugging Face Jobs. It supports methods like SFT, DPO, GRPO, and reward modeling, including GGUF conversion for local deployment. Use this skill for cloud GPU training tasks, GGUF conversion, or when users mention training on Hugging Face Jobs without local GPU setup, leveraging the TRL Jobs package and related tools.
