hugging-face-model-trainer

Trains and fine-tunes language models on Hugging Face's cloud GPU infrastructure using TRL. Supports SFT, DPO, GRPO, and reward modeling. Handles job submission, dataset validation, cost estimation, and GGUF conversion for local deployment. Instead of manually managing cloud VMs, writing job configs, and remembering to push checkpoints before the environment is destroyed, this skill handles submission, Hub authentication, timeout sizing, and Trackio monitoring as part of a single workflow.
