Introducing Unsloth Studio!

[shimmyshimmer]

Hey guys, we're super excited to launch Unsloth Studio, a new open-source web UI to train and run LLMs.

Blog + everything you need to know: https://unsloth.ai/docs/new/studio

• Run models locally on Mac, Windows, Linux
• Compare and battle models side-by-side
• Train 500+ models 2x faster with 70% less VRAM
• Supports GGUF, vision, audio, embedding models
• Self-healing Tool calling / web search + code execution
• Auto-create datasets from PDF, CSV, DOCX
• Export models to GGUF, safetensor and more formats

HUZZAHHHH!!!

[PmNz8]

Thanks for releasing this great tool! Any chances you consider adding simple native installer for windows platform in the future?

[shimmyshimmer]

Working on it! An exe too :)

[adrianpuiu]

guys, please add mcp tool support so we can use the mcp tools when generating synthetic datasets

[Shine1i]

You can already do that! Just add a tool config block and connect it to LLM blocks ! You can add mcps there
