Choosing the Right AI Fine-Tuning Tool

If you want to train your own AI model, you have four main options to choose from. Unsloth, Axolotl, TRL, and LLaMA-Factory all work with the same core technology. Even though they share the same foundation, they focus on very different goals.

Unsloth is built for speed and saves memory by rewriting internal code. Axolotl focuses on helping you run tasks across multiple graphics cards. TRL provides the basic training tools that others often use to build their own systems.

LLaMA-Factory is the best choice if you need to support many different types of models. You should pick your tool based on whether you care more about raw speed or having a wide range of features. Think about your hardware limits before you start training.
