It’s becoming a developer workflow. **[All Things Open](https://daily.dev/sources/allthingsopen)** · 8 min read · 0 upvotes · 0 comments ## Summary LLM fine-tuning has shifted from a research-lab activity to a practical developer workflow, thanks to open source tools like Unsloth, Axolotl, LoRA, and QLoRA. The post walks through the full fine-tuning stack layer by layer — dataset preparation (Hugging Face Datasets), efficient training (LoRA/QLoRA reducing trainable parameters by ~90%), orchestration (Axolotl, Unsloth, LLaMA-Factory, TRL, torchtune), scaling (DeepSpeed, FSDP), evaluation (lm-eval-harness plus custom test sets), and deployment (vLLM, llama.cpp, Ollama with LoRA adapters). A concrete support-ticket classification example shows a team achieving 98% accuracy for under $100 in training costs. The post also clarifies when to choose fine-tuning over RAG or prompting: fine-tuning is best for stable, repeatable behavioral tasks, while RAG suits volatile knowledge and prompting handles simpler cases. The emerging 2026 consensus is to combine all three approaches in production. ## Full article daily.dev links to this article rather than hosting it.
