There's a link to the GitHub project at the top of the linked webpage. Sorry: would be happy to just post here for you to save you a step, but something is acting up with my clipboard.
i got this installed and it works insanely well. Some of the models are laughably bad at math, (similar to chatgpt) in that they know the concepts but mix up the numbers, still it does a great job and I will probably never use chatGPT again.
Also for anyone who doesn't think it will work on their distro it runs great on fedora. (fedora user fyi)
