# Unsloth - Fast LLM Fine-Tuning

Fine-tune LLMs 2-5x faster with 50-80% less VRAM. Supports SFT, RL (GRPO), vision, TTS, and 300+ models with zero accuracy loss.

## When to Use Unsloth

**Use Unsloth when:**
- Fine-tuning on a single GPU with LoRA/QLoRA (consumer or datacenter)
- Training reasoning models with GRPO, Dr. GRPO, DAPO, BNPO, or GSPO
- Fine-tuning vision models (Qwen3-VL, Gemma 3, Llama 3.2 Vision)
- Fine-tuning TTS models (Orpheus, Sesame-CSM, Whisper)
- Exporting to GGUF for Ollama, llama.cpp, or LM Studio
- Need padding-free training and uncontaminated packing (automatic)
- Using FP8 precision for additional memory savings on Ampere+ GPUs
