Oh man, I had literally this exact idea too (although targeting general GPU workloads, not AI specifically). I actually wrote a pretty detailed product roadmap/desiderata/business plan/basic market research/etc note about it.

I ended up not pursuing it to work on a different idea, feeling like Golem would probably eat that lunch. I love the simplicity of your approach - very in the spirit of an mvp. Let me know if you'd like to see the note (teaser: an ad that says "Because not everyone has a 500 GPU cluster", but "not" is crossed out and replaced with "now", over a background image of a Go board).

Anyways, best of luck, I'll be excited to see how it turns out!

This is awesome. Is it necessary that the PC remain fully online throughout the day? I wouldn't mind putting my PC out there but sometimes when I get back from work my modem or router has crapped out and I need to restart things (not the PC), and I've been told it's a few thousand (over 3, actually) to wire up the house with Ethernet so I live with the status quo for now

You can list your computer for as long as you like! It's up to the ML/AI researchers to decide which machines they want to use based on the specs they see, and for how long.

What happens if the computer is taken offline before the task is done?

The GPU owner gets no payment for the entire task.

I saw people on the Reddit thread saying the Ubuntu requirement was a showstopper for a lot of them.

You might look into the Win 10 linux support, Ubuntu is one o the supported distros. Not sure if it would have full access to resources, have just used it a bit at work and setup was super simple.

I remember a few weeks ago a when some Microsoft software engineers came to the career fair at Univ. of Maryland. One of them was working on Bash on Ubuntu on Windows, so I ended up bugging him for about an hour on when they'd support GPU passthrough for Ubuntu on Windows.

He said it was on their list of most requested features, but refused give me a data on when it would be ready :/

Kind-of +1 about this, I don't really want to run dedicated Ubuntu for something like this but I have no problem running virtualized Ubuntu with GPU via VTd passthru. Recently we've built such host - server board with 2 GPUs that now runs two powerful virtualized desktops. Host uses NixOS and libvirt.

You mention "free unlimited bandwidth" on the homepage in a column named "1 TB transfer". A lot of people have upstreams in the order of 1MBit/s – with such speeds, uploading a TB would take 92 days.

That seems misleading ^^.

Agreed! A lot of hosts have requested for the ability to set a bandwidth cap. I'll change that part of the site & be a bit more clear!
