Unsloth vs Axolotl vs TRL vs LLaMA-Factory: A Fine-Tuning Framework Comparison on Speed, VRAM, and Multi-GPU

A comparison of four open-source LLM fine-tuning frameworks—Unsloth, Axolotl, TRL, and LLaMA-Factory—shows their distinct engineering priorities. Unsloth focuses on kernel rewrites for speed, Axolotl on parallelism strategies, TRL on trainer APIs, and LLaMA-Factory on broad model coverage. The article explores trade-offs in speed, VRAM usage, and multi-GPU support.

Why it matters: This comparison informs developers about the strengths of each framework, aiding in selecting the best tool for specific fine-tuning requirements.
