Unsloth is an open-source framework for fine-tuning large language models up to 2x faster while using 70% less VRAM. Built with custom Triton kernels, it supports 500+ model architectures including Llama 4, Qwen 3, and DeepSeek on consumer NVIDIA GPUs. Unsloth Studio adds a no-code web UI for dataset creation, training observability, model comparison, and GGUF export for Ollama and vLLM deployment.
Unsloth provides an open-source LLM fine-tuning library (Apache 2.0) that is 2x-5x faster with 80% less VRAM on single GPUs. Commercial Pro and Enterprise tiers offer multi-GPU scaling (up to 8 GPUs), multi-node support, and full parameter fine-tuning via custom sales quotes.Review →
