This private Space has two HF-specific runners based on the customer Colab notebooks:
Quick Comparison: a short AdamW vs lbw_guard WikiText LoRA run.
Ablation Matrix: a selectable scenario sweep across optimizer, LR, schedule, steps, data, and LoRA rank.
Each run writes JSON and CSV artifacts. GPU hardware is recommended; CPU mode is only for tiny smoke checks.
Runs the HF version of the Easy Test flow: one shared WikiText slice, then AdamW and optional lbw_guard LoRA training with final perplexity and gain CSV output.
