Reddit user wants to learn fine-tuning (QLoRA/RL LoRA) before spending money

A Reddit user asks how to learn local model fine-tuning deeply before spending money.
- They note a flood of new techniques: RL, RL LoRA, QLoRA, CPT LoRA, and believe they have a use case but don't know where to learn.
- YouTube search yields low-quality tutorials, and good channels (fireship, bycloud) don't cover these newer concepts.
- They want "practical depth" to successfully fine-tune Qwen 27B on a custom corpus without spending $100 only to find they didn't need CPT or picked the wrong rank and wasted a two-day run.
Context: they're building a legal general-purpose chatbot with a large corpus and are stuck on next steps, asking the community for pointers.
