Unsloth

Open-source local AI workstation: download models and chat directly on the desktop, fine-tune models without writing code, locally generate and edit images and videos, and connect coding agents to your own GPU.

What is Unsloth?

Unsloth first made a name for itself as a "lightning-fast fine-tuning" Python library, and now it has launched Unsloth Desktop—what the company calls "the first desktop application to run and train AI models"—which is open-source, free, and runs 100% locally. It integrates model downloading, chatting, fine-tuning, and image and video generation into a no-code desktop workspace. Officially positioned as "Your complete local AI workspace", it makes local AI no longer just a toy for command-line enthusiasts. The company states that you can get started by "downloading a model and starting to chat within minutes". It also emphasizes that local models can "actually run code" and support "accessing models anywhere".

Who is it for?

Researchers and developers who have a local graphics card and are concerned about data leakage; individual users who want to try fine-tuning at a low cost without having to grapple with training frameworks; teams that hope to use local models to power coding agents and reduce reliance on APIs; and internal corporate scenarios that require keeping code and data entirely local are also applicable.

Key features

Local Chat

Download a model and start chatting within minutes, with all data staying on your device; the official provides a model library page where you can browse the latest open-source models and download them as needed, with full local management of models and workspaces.

No-Code Fine-Tuning

Officially described as an open-source, no-code desktop UI, it provides a visual fine-tuning workflow without the need to write training scripts, making it suitable for quickly verifying the feasibility of "fine-tuning models on proprietary data".

Image and Video Generation

Supports models like MiniMax-H3, FLUX, and Z-Image for image generation, and models such as Wan and LTX for video generation; also enables local editing operations including inpaint, extend, upscale, and reference-based image editing.

Connect Coding Agents

You can connect agents like Claude Code and Codex to your own GPU, allowing them to run on top of local models.

Latest Models & Online Retrieval

Continuously follow up on newly released open-source models such as Qwen and GLM (Qwen3.8-Flash-Next, GLM-5.3-Flash, etc. are displayed on the official website), and integrate Advanced Web search.

How to use Unsloth

First download a small model to get dialogue running and experience local inference.
then try fine-tuning a domain dataset with a no-code workflow to verify the entire process.
high-load tasks like video generation are recommended to run on a dedicated GPU.
Official tutorials and model libraries are updated frequently, so check the hardware requirements of the target model before getting started to avoid downloading only to find it can't run.
In data-sensitive scenarios, local operation itself is the biggest security advantage.

Things to know

Performance depends on the graphics card: The official video generation samples are based on high-end cards such as the NVIDIA B200 (960×544, 124 frames, 13 seconds), and consumer-grade devices need to lower expectations significantly.

A macOS version is available for download, but heavy-duty training and image generation are still recommended on the NVIDIA platform.

Running locally means you have to manage your model files and disk space yourself, and large models are often tens of gigabytes in size.

The first-time download of models and the initial operation for image generation take a long time, which is significantly affected by network and hard disk speeds.

The specific effects of fine-tuning and generation vary with model versions, and the parameters in the official examples may not be applicable to your data, requiring independent experimentation.

The capabilities of open-source models still lag behind those of the latest cloud-based flagship models, and you need to evaluate them yourself for key tasks.

The desktop application occupies both memory and video memory at the same time. Pay attention to resource competition when running multiple tasks such as conversation, fine-tuning, and image generation.
