DECISION GUIDE
When to pick each, and when to skip both.
Three plain-English paths: the case for Unsloth, the case for Axolotl, and the free bring-your-own-key route that avoids seat fees entirely.
When to Pick Unsloth
94.5 / 100- 78k+ GitHub stars; custom Triton kernels cut QLoRA VRAM by 70% and double training speed
- Fits 14B-32B parameter QLoRA fine-tunes on a single 24GB consumer GPU or free Colab
- Direct 1-command export to GGUF (llama.cpp), Ollama, and vLLM
When to Pick Axolotl
91.5 / 100- 12.5k+ GitHub stars; declarative single-YAML config for multi-node FSDP and DeepSpeed ZeRO-3
- First-class support for RLHF, DPO, ORPO, and multimodal dataset packing
- Turnkey cloud cluster launch templates for multi-node H100 training runs
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.
