Can I be controversial and ask what justifies such expenses? Why is this game so important that it needs to be up and running so badly? From what I've seen so far the "game" (if you can even call it that) highlights the weaknesses of GPT-2 much more than its strengths (the model's answers to user actions are random, the story is incoherent, the world is inconsistent). I don't get the feeling it was setup to demonstra…

Not blaming them, but still a nice example to illustrate the myth that 'the cloud' will let you operate without a sysadmin (someone that knows about setting up and managing infrastructure). Yes, there might not be servers you have to rack and electrical power to be provisioned, but the amount and granularity of the parameters and decisions on the virtual fabric to be decided on and continuously monitored for changes…

Also not blaming him/them but isn't this an indicator of lack of cost control at research facilities? Surely someone should of costed this out before making it public? Here in the UK running at 10k/day would of ruined a departments budget for an entire year!

Costing for cloud solutions is often not trivial, and a single overlooked parameter can do you in. I at least blame Google partially for having quotas and spending limits set to unlimited by default.

They are seeing 60k downloads of 6GB models per day, which is about 33Gbps of bandwidth (assuming no burstiness in when people visit, which is a poor assumption). That is starting to get out of the range of what is easily available. 10Gbps circuits are commodities (I had one at my desk at my last job), but 100Gbps circuits are still pretty pricey. And, it's not necessarily trivial to get that kind of throughput on fi…

> 60k downloads of 6GB models per day Wait... you mean the actual computation is running client in the browser? I didn't even open this "game", but I assumed such high cost is because there is a separate GPT-2 running on a GPUs for each and every user.

No, the models are running in Colab - but in the end-user's account - so each 'run' costs the lab 6GB of internet egress when the model is downloaded from GCS to the Colab VM.

No, the computation is not running on the client in the browser. This is the traffic to transfer the model from GCS to Google Colab.

This is what makes the price so surprising - you are copying data from one Google Service to another, but it's billed as egress.

Probably because they have to spend their grant money some way.

One hears stories about researchers with unspent grant money scrambling madly to find something, anything, to spend it on before the grant expires. Use it or lose it. My Dad told me how back in the 1970s he worked at a government-funded research lab. One time they called up a laboratory glassware supplier and said "We'd like to order $10,000 worth of glassware". The supplier asked "Sure, what specifically would you l…

I came across a similar thing in the 90s; one department had an expensive piece of equipment with a three year lifespan.

They weren't allowed to amortise that, and any budget increase every three years would have been denied, so they had to include the whole replacement cost in every budget, and find ways of spending that money every year, or lose it.

Ooof, yes, now I see where the $10K/day is coming from... As I have demonstrated, I've really not much of a clue when it comes to AI, but do users really need 12Gb GPU RAM, 100% of the time? Maybe it's possible to use one GPU for multiple users?

Google Colab gives each user a dedicated Nvidia Tesla K80 GPU for 12 hours for free, which is super cool and presumably why the project is on Colab. But as each user spins up their own Colab instance it pulls down the 6GB of GPT-2 model weights, incurring 30-40 cents of data egress charges against the GCP Storage Bucket that the data is stored in. 60k users yesterday * 6GB each -> 360TB of data egress! Normally, a sc…

But you could set up your own file-serving node and then data transfer to end-user Colab instances would be free, right? ("Free" — costing only as much your CDN costs for 360TB/day, which is still quite pricey, I think, but not as much as $10K/day. I.e. Google wouldn't charge you for data transfer here.)

Wait, wait, this is a university developing something, that needs to be downloaded, they choose a commercial solution for that, and that costs them $10k per day? They don't have their own file-hosting solutions? At a university with an AI dept? With that money ("for a couple of days"), you could buy your own server and do it yourself, for a fraction of the price. And don't tell me you can't find people who'd be capab…

As an "SRE engineer", I don't agree. Certainly in an university/R&D environment, you cannot compete with what 'the cloud' is able to offer within the reach of a few mouse clicks. It would be absolutely moronic to set up an entire infra yourself with GPU's, ... specifically tailored to for 1 research project to then throw it away after a few months, or see the scope change every 2 weeks. One of the reasons such AI tec…

At 10k per day it is absolutely worth it to hire someone to take care of a bunch of cheap servers.

I had a lot of fun playing the game. I think this game shows us how interesting AI technology will become in the 2020s. It’s open ended but somewhat incoherent right now, but I think we’ll figure out how to update this kind of technology to have an open ended yet internally consistent world by the end of the 2020s.

As it turns out, it’s actually possible to bona fide win the game. In my case, I was dating two girls, one was uncomfortable with the other girl, and broke up with me, so I asked the remaining girl if she would marry me. At this point, she said yes, we rode off in to the sunset and the game proclaimed “CONGRATS YOU WIN” then it saves the game for me. I guess I could load the game and deal with domestic squabbles, hav…

Torrent trick?

Uh, I mean, of course I don't know any better than you, but I think parent wasn't entirely serious... obviously. Was he?

Why is Cloudflare a dirty word around here? I'm afraid I'm out of the loop

There's one particular commentator who is very vocal about his disdain for Cloudflare.

Never noticed. What's his problem though?
