* On Windows and Linux, building GPT4All requires the complete Vulkan SDK. You may download it from here: https://vulkan.lunarg.com/sdk/home
|
||||
* macOS users do not need Vulkan, as GPT4All will use Metal instead.
|
||||
* CUDA Toolkit >= 11.4 (you can bypass this with adding a custom flag to build step)

- Windows: There is difficulty compiling with cuda if the Visual Studio IDE is NOT present.

Using npm

```sh

The `build:runtimes` script will create runtime libraries for your platform in `runtimes` and `build:prebuilds` will create the bindings in `prebuilds`. `build` is a shortcut for both.
