Our Take

Unsloth is nailing the efficiency game for running LLMs locally, which sounds simple but actually matters a ton when you're trying to fine-tune models without burning through cloud costs. Their day-0 support for Gemma 4 tells me they have real connections with the major labs, not just a marketing angle — they actually got in the door when it mattered. If you're building anything with LLMs and don't want to bleed money on API calls every time you iterate, this is worth a look.

Unsloth Studio runs 100% offline on Mac and Windows devices. It runs GGUF and Safetensors models with tool-calling, web search, and OpenAI compatible API. The platform supports custom kernels for optimized training for LoRA, FP8, FFT, PT and 500+ models including text, vision, audio and embeddings.

Key Features

Run models locally 100% offline, GGUF and Safetensors support, Tool-calling and web search, OpenAI compatible API, No-code training with dataset creation from PDF, CSV, JSON, Model Arena for side-by-side model comparison, Data Recipes for document-to-dataset transformation, Export to safetensors, GGUF, llama.cpp, vLLM, Ollama, Custom kernels for LoRA, FP8, FFT, PT, MultiGPU support (Pro and Enterprise), Audio, vision, and embedding support
