Unsloth
FreemiumOpen-source library for faster, low-memory LLM fine-tuning
What is Unsloth?
Unsloth is an open-source library that fine-tunes and trains language, vision and audio models about twice as fast with much less GPU memory. It lets developers fine-tune mid-sized models on a single consumer GPU or a free Colab notebook.
Custom kernels and dynamic quantization cut memory use for LoRA, QLoRA, full fine-tuning and reinforcement learning. Unsloth Studio adds a local browser interface for no-code training and chat.
The team also publishes quantized GGUF versions of new open models and fixes for model bugs. The core library is free under Apache 2.0, with paid Pro and Enterprise tiers for multi-GPU speedups.
