irm https://unsloth.ai/install.ps1 | iex
```
> [!WARNING]
> **DO NOT USE `unsloth studio update` since packaging will not get the latest updates**


## Mac Updates
* Re-enabled `llama.cpp` prebuilt binaries for Apple Silicon (M1-M4) - Mac OS 14 / 15 / 26 (Tahoe)
* Apple Silicon Mac OS 13 (Ventura) is source build
* Intel (x86_64) for Mac OS 13.3 / 14 / 15 / 26 (Tahoe) uses `llama.cpp` prebuilt binaries
* Intel for Max 13.0 - 13.2 is source build

## Windows Updates
* CUDA 13.3 `llama.cpp` prebuilt binaries now work for Windows
* For CUDA 13.2, CUDA 13.1 and below, Windows devices uses CUDA 12.4 fallback - we'll work on CUDA 13.1 binaries soon.

## CUDA 13.3 Update
* CUDA 13.3 non Linux binaries work. We'll still use CUDA 13.1 for now
* CUDA 13.3 solves the CUDA 13.2 gibberish problem - see https://github.com/unslothai/unsloth/issues/4849

## Blackwell GPUs Update
* For now Blackwell will have delayed releases of `llama.cpp` prebuilt binaries sine CUDA 12.4 does not work - we are working to resolve this soon.
