Cut my training memory usage in half instantly. Absolute legend of a toolkit.
Running local models and fine-tuning on my own GPU has never been this smooth.
Blazing fast training.
CLI can be finicky sometimes.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Train and run nearly every major open model locally, with Day Zero support for new releases and a built-in hub that helps you pick the right quantization for your device.
Fine-tune with efficient methods and reinforcement learning while using noticeably less memory and completing runs faster than standard workflows.
Generate and edit images with models like Qwen-Image, FLUX and Z-Image, plus LoRA adapters, and create video with Wan and LTX.
Connect agents like Claude Code and Codex to your local models with a single command, or expose an OpenAI-compatible API for existing apps.
Run private web searches, follow links with browser use, produce cited research reports, and execute Bash or Python in a sandbox with permissions you define.
Unsloth is an open-source project focused on making large language models practical to run and train on hardware you actually own. It became widely known for efficient fine-tuning that cuts memory use and speeds up training, and the current product has grown into a full local AI stack: download a model, chat with it, connect it to your tooling and generate images or video alongside.
The workflow starts with the built-in model hub, which helps you find and download the quantisation that suits your device with Day Zero support for new releases. From there you can train or fine-tune with efficient methods including reinforcement learning, connect agents such as Claude Code and Codex using a single start command, and swap models without changing your agent setup. An OpenAI-compatible API means existing applications, scripts and SDKs can talk to local models through a familiar interface.
Unsloth also bundles the surrounding capabilities that make a local model genuinely useful: private web search and deep research with citations, browser use where the model can follow links and fill in forms, and sandboxed execution of Bash and Python with permissions you set for file and network access. Because it runs on your own machine or a Colab notebook, data stays under your control, and you can optionally serve a model over HTTPS through a free Cloudflare tunnel to reach it from other devices.
Adapt an open model to your own dataset on a single GPU using efficient fine-tuning, then serve it locally behind an OpenAI-compatible API.
Run a capable model on your own laptop or desktop and point Claude Code or another agent at it, keeping proprietary code off third-party servers.
Research a topic offline with private web search and deep research, and let the model follow links and complete forms in a browser beside the chat.
Generate and edit images with models like FLUX or Qwen-Image and produce short video with Wan or LTX, applying LoRA adapters for a specific style.
