Unsloth
A fine-tuning library focused on speed and low memory use, with optimised kernels that make LoRA and QLoRA training much faster and lighter. It is the tool to reach for when you want to fine-tune on a single consumer GPU.
Strengths
- Much faster training with far lower VRAM through optimised kernels
- Great for LoRA and QLoRA on a single consumer card
- Apache 2.0, with an open web UI in Unsloth Studio
Weaknesses
- Single-GPU focus, so less suited to large multi-GPU runs
- CUDA-centric, so mainly for NVIDIA hardware
- Fine-tuning still needs a solid grasp of the process to get good results
