DECISION GUIDE
When to pick each, and when to skip both.
Three plain-English paths: the case for Unsloth, the case for LLaMA-Factory, and the free bring-your-own-key route that avoids seat fees entirely.
When to Pick Unsloth
95.4 / 100- 78,115+ GitHub stars with handwritten Triton backpropagation kernels cutting 8B QLoRA VRAM to 6.8GB (-70%)
- Trains 50k instruction rows for $1.85 on a single GPU vs $62.50 on managed cloud fine-tuning APIs (-97.0%)
- 1-click zero-loss quantization export to GGUF (llama.cpp/Ollama) and vLLM
When to Pick LLaMA-Factory
94.8 / 100- 75,518+ GitHub stars with turnkey LlamaBoard Gradio WebUI for zero-code dataset prep, training, and evaluation
- Supports 100+ text and multimodal vision-language models across SFT, QLoRA, DPO, ORPO, KTO, and PPO
- Integrates Unsloth, Liger Kernel, FlashAttention-2, and DeepSpeed ZeRO-3 under one unified CLI
When to Skip Both (BYOK OSS)
Aider / Cline- $0/mo Seat Fee: Pay pure upstream Anthropic/DeepSeek/OpenAI API rates or run local Ollama models for $0.
- Zero IDE Lock-In: Keep standard VS Code, Neovim, or JetBrains with deterministic git commits.
- 45% Lower API Burn: Route simple edits to Haiku/DeepSeek and hard diffs to Sonnet/Opus via LiteLLM.
