Unsloth vs Axolotl vs TRL vs LLaMA-Factory: A Fine-Tuning Framework Comparison on Speed, VRAM, and Multi-GPU
Four open supply tasks dominate LLM fine-tuning at present. Unsloth, Axolotl, TRL, and LLaMA-Factory all wrap the identical underlying PyTorch and Hugging Face stack. They diverge on the place they spend engineering effort. Unsloth rewrites kernels. Axolotl composes parallelism methods. TRL defines the coach APIs the others construct on. LLaMA-Factory optimizes for breadth of mannequin…
