The Goal

The goal of nixified.ai is to simplify and make available a large repository of AI executable code that would otherwise be impractical to run yourself, due to package management and complexity issues.

The outputs run primarily on NixOS and-or Linux, but can also run on Windows via NixOS-WSL. It is able to utilize the GPU of the Windows host automatically, as our wrapper script sets LD_LIBRARY_PATH to make use of the host drivers.

You can explore all this flake has to offer through the nix repl (tab-completion is your friend):

$ nix repl
nix-repl> :lf github:nixified-ai/flake
Added 26 variables.

The main outputs of the flake.nix at the moment are as follows:

ComfyUI ( A modular, node-based Stable Diffusion WebUI )

(warning: this will give you an empty comfyui without custom_nodes or models, see flake-modules/projects/comfyui/README.md for information on how to configure and use comfyui)

• nix run github:nixified-ai/flake/2aeb76f52f72c7a242f20e9bc47cfaa2ed65915d#invokeai-nvidia
• nix run github:nixified-ai/flake/2aeb76f52f72c7a242f20e9bc47cfaa2ed65915d#invokeai-amd (Broken due to lack of Nixpkgs ROCm support)

Deprecated Packages (Due to lack of funding)

InvokeAI ( A Stable Diffusion WebUI )

(warning: unmaintained - you have to use the last working commit in order to use it)

• nix run github:nixified-ai/flake/2aeb76f52f72c7a242f20e9bc47cfaa2ed65915d#invokeai-amd
• nix run github:nixified-ai/flake/2aeb76f52f72c7a242f20e9bc47cfaa2ed65915d#invokeai-nvidia

textgen ( Also called text-generation-webui: A WebUI for LLMs and LoRA training )

(warning: unmaintained - you have to use the last working commit in order to use it)

• github:nixified-ai/flake/2aeb76f52f72c7a242f20e9bc47cfaa2ed65915d .#textgen-amd
• github:nixified-ai/flake/2aeb76f52f72c7a242f20e9bc47cfaa2ed65915d .#textgen-nvidia

Enable binary cache

To make the binary substitution work and save you some time building packages, you need to tell nix to trust nixified-ai's binary cache. On nixos you can do that by adding these 2 lines to /etc/nixos/configuration.nix and rebuilding your system:

nix.settings.trusted-substituters = ["https://ai.cachix.org"];
nix.settings.trusted-public-keys = ["ai.cachix.org-1:N9dzRK+alWwoKXQlnn0H6aUx0lU/mspIoz8hMvGvbbc="];

If you are on another distro, just add these two lines to /etc/nix/nix.conf. In fact the line trusted-public-keys = ... should already be there and you only need to append the key for ai.cachix.org.

trusted-substituters = https://ai.cachix.org
trusted-public-keys = cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY= ai.cachix.org-1:N9dzRK+alWwoKXQlnn0H6aUx0lU/mspIoz8hMvGvbbc=
