It takes a lot to be able to find something in yourself like that and admit it to yourself and everyone. I always appreciate people like that. I also tried the playground and was impressed that it was free! It must be a sizable chunk of money to run that.

Believe it or not, it's completely free. It's thanks to TFRC. It's the most world-changing program I know of. It's why I go door to door like the proverbial religious fanatic, singing TFRC's praises, whether people want to listen or not. Because for the first time in history, any capable ML hacker now has the resources they need to do something like this. Imagine it. This is a legit OpenAI-style model inference API. It's now survived two HN front page floods. (I saw it go down about an hour ago, so I was like "Nooo! Prove you're production grade! I believe in you!" and I think my anime-style energy must've brought it back up, since the API works fine now. Yep, it was all me. Keyboard goes clackclackclack, world changes, what can I say? Just another day at the ML office oh god this joke has gone on for like centuries too long.) And it's all thanks to TFRC. I'm intentionally not linking anything about TFRC, because in typical google fashion, every single thing you can find online is the most corporate, soulless-looking "We try to help you do research at scale" generic boilerplate imaginable. So I decided to write something about TFRC that wasn't: https://blog.gpt4.org/jaxtpu https://blog.gpt4.org/jaxtpu (It was pretty hard to write a medieval fantasy-style TPU fanfic, but someone had to. Well, maybe no one had to. But I just couldn't let such a wonderful project go unnoticed, so I had to try as much stupid shit as possible to get the entire world to notice how goddamn cool it is.) To put things into perspective, a TPU v2-8 is the "worst possible TPU you could get access to." They give you access to 100. On day one. This is what originally hooked me in. My face, that first day in 2019 when TFRC's email showed up saying "You can use 100 v2-8's in us-central1-f!": https://i.imgur.com/EznLvlb.png https://i.imgur.com/EznLvlb.png The idea of using 100 theoretically high-performance nodes of anything, in creative ways, greatly appealed to my gamedev background. It wasn't till later that I discovered, to my delight, that these weren't "nodes of anything." These are 96 CPU, 330GB RAM, Ubuntu servers. That blog post I just linked to is running off of a TPU right now. Because it's literally just an ubuntu server. This is like the world's best kept secret. It's so fucking incredible that I have no idea why people aren't beating down the doors, using every TPU that they can get their hands on, for as many harebrained ideas as possible. God, I can't even list how much cool shit there is to discover. You'll find out that you get 100Gbit/s between two separate TPUs. In fact, I'm pretty sure it's even higher than this. That means you don't even need a TPU pod anymore. At least, theoretically. I tried getting Tensorflow to do this, for over a year. kindiana (Ben Wang), the guy who wrote this GPT-J codebase we're all talking about, casually proved that this was not merely theoretical: https://twitter.com/theshawwn/status/1406171487988498433 https://twitter.com/theshawwn/status/1406171487988498433 He tried to show me https://github.com/kingoflolz/swarm-jax/ https://github.com/kingoflolz/swarm-jax/ once, long ago. I didn't understand at the time what I was looking at, or why it was such a big deal. But basically, when you put each GPT layer on a separate TPU, it means you can string together as many TPUs as you want, to make however large of a model you want. You should be immediately skeptical of that claim. It shouldn't be obvious that the bandwidth is high enough to train a GPT-3 sized model in any reasonable time frame. It's still not obvious to me. But at this point, I've been amazed by so many things related to TPUs, JAX, and TFRC, that I feel like I'm dancing around in willy wonka's factory while the door's wide open. The oompa loompas are singing about "that's just what the world will do, oompa-loompa they'll ignore you" while I keep trying to get everybody to stop what they're doing and step into the factory. The more people using TPUs, the more google is going to build TPUs. They can fill three small countries entirely with buildings devoted to TPUs. The more people want these things, the more we'll all have. Because I think Google's gonna utterly annihilate Facebook in ML mindshare wars: https://blog.gpt4.org/mlmind https://blog.gpt4.org/mlmind TPU VMs just launched a month ago. No one realizes yet that JAX is the React of ML. Facebook left themselves wide open by betting on GPUs. GPUs fucking suck at large-scale ML training. Why the hell would you pay $1M when you can get the same thing for orders of magnitude less? And no one's noticed that TPUs don't suck anymore. Forget everything you've ever heard about them. JAX on TPU VMs changes everything. In five years, you'll all look like you've been writing websites in assembly. But hey, I'm just a fanatic TPU zealot. It's better to just write me off and keep betting on that reliable GPU pipeline. After all, everyone has millions of VC dollars to pour into the cloud furnace, right? TFRC changed my life. I tried to do some "research" https://www.docdroid.net/faDq8Bu/swarm-training-v01a-pdf https://www.docdroid.net/faDq8Bu/swarm-training-v01a-pdf back when Tensorflow's horrible problems were your only option on TPUs. Nowadays, you can think of JAX as "approximately every single thing you could possibly hope for." GPT-J is proof. What more can I say? No TFRC, no GPT-J. The world is nuts for not noticing how impactful TFRC has been. Especially TFRC support. Jonathan from the support team is just ... such a wonderful person. I was blown away at how much he cares about taking care of new TFRC members. They all do. (He was only ever late answering my emails one time. And it was because he was on vacation!) If you happen to be an ambitious low-level hacker, I tried to make it easier for you to get your feet wet with JAX: 1. Head to https://github.com/shawwn/jaxnotes/blob/master/notebooks/001_jax.ipynb https://github.com/shawwn/jaxnotes/blob/master/notebooks/001... 2. Click "Open in Collaboratory" 3. Scroll to the first JAX section; start reading, linearly, all the way to the bottom. I'd like to think I'm a fairly capable hacker. And that notebook is how I learned JAX, from zero knowledge. Because I had zero knowledge, a week or two ago. Then I went from tutorial to tutorial, and copied down verbatim the things that I learned along the way. (It's still somewhat amazing to me how effective it is to literally re-type what a tutorial is trying to teach you. I'd copy each sentence, then fix up the markdown, and in the process of fixing up the markdown, unconsciously osmose the idea that they were trying to get across.) The best part was, I was connected remotely to a TPU VM the whole time I was writing that notebook, via a jupyter server running on the TPU. Because, like I said, you can run whatever the hell you want on TPUs now, so you can certainly run a jupyter server without breaking a sweat. It's so friggin' nice to have a TPU repl. I know I'm just wall-of-text'ing at this point, but I've literally waited two years for this to come true. (There's a fellow from the TPU team who DMs with me occasionally. I call him TPU Jesus now, because it's nothing short of a miracle that they were able to launch all of this infrastructure -- imagine how much effort, from so many teams, were involved in making all of this possible.) Anyway. Go read https://github.com/shawwn/website/blob/master/mlmind.md https://github.com/shawwn/website/blob/master/mlmind.md to get hyped, then read https://github.com/shawwn/website/blob/master/jaxtpu.md https://github.com/shawwn/website/blob/master/jaxtpu.md to get started, and then read https://github.com/shawwn/jaxnotes/blob/master/notebooks/001_jax.ipynb https://github.com/shawwn/jaxnotes/blob/master/notebooks/001... to get effective, and you'll have all my knowledge. In exchange for this, I expect you to build an NES emulator powered by TPUs. Do as many crazy ideas as you can possibly think of. This point in history will never come again; it feels to me like watching the internet itself come alive back in the 80's, if only briefly. It's like having a hundred raspberry pis to play with, except every raspberry pi is actually an ubuntu server with 96 CPUs and 330GB of RAM, and it happens to have 8 GPUs, along with a 100Gbit/s link to every other raspberry pi.

  I love the enthusiasm, but is this another Google thing that is for researchers only? Yes fantastic technology etc, but say you develop something on the infrastructure then go to commercialise, what do you do? I don't know much about the ML space, but is this a bit like Google Earth Engine, amazing tech, very generous resources free for researchers and development but cannot be ported elsewhere so to commercialise you then are limited to this very environment which is not cheap. I recently reached out to Google for pricing on GEE, 3 weeks later I got a response. 3 weeks.

    Your view here is entirely reasonable. It was my view before I ever heard about TFRC. I was every bit as skeptical. That view is wrong. From https://github.com/shawwn/website/blob/master/jaxtpu.md https://github.com/shawwn/website/blob/master/jaxtpu.md : > So we're talking about a group of people who are the polar opposite of any Google support experience you may have had. > Ever struggle with GCP support? They took two weeks to resolve my problem. During the whole process, I vividly remember feeling like, "They don't quite seem to understand what I'm saying... I'm not sure whether to be worried." > Ever experience TFRC support? I've been a member for almost two years. I just counted how many times they failed to come through for me: zero times. And as far as I can remember, it took less than 48 hours to resolve whatever issue I was facing. > For a Google project, this was somewhere between "space aliens" and "narnia" on the Scale of Surprising Things. [...] > My goal here is to finally put to rest this feeling that everyone has. There's some kind of reluctance to apply to TFRC. People always end up asking stuff like this: > "I'm just a university student, not an established researcher. Should I apply?" > Yes! > "I'm just here to play around a bit with TPUs. I don't have any idea what I'm doing, but I'll poke around a bit and see what's up. Should I apply?" > Heck yeah! > "I have a Serious Research Project in mind. I'd like to evaluate whether the Cloud TPU VM platform is sufficient for our team's research goals. Should I apply?" > Absolutely. But whoever you are, you've probably applied by now. Because everyone is realizing that TFRC is how you accomplish your research goals. I expect that if you apply, you'll get your activation email within a few hours. Of course, you better get in quick. My goal here was to cause a stampede. Right now, in my experience, you'll be up and running by tomorrow. But if ten thousand people show up from HN, I don't know if that will remain true. :) I feel a bit bad to be talking at length at TFRC. But then I remembered that none of this is off-topic in the slightest. GPT-J was proof of everything above. No TFRC, no GPT-J. The whole reason that the world can enjoy GPT-J now is because anyone can show up and start doing as many effective things as you can possibly learn. It was all thanks to TFRC, the Cloud TPU team, the JAX team, the XLA compiler team -- hundreds of people, who have all managed to gift us this amazing opportunity. Yes, they want to win the ML mindshare war. But they know the way to win it is to care deeply about helping you achieve every one of your research goals. Think of it like a side hobby. Best part is, it's free. (Just watch out for the egress bandwidth, ha. Otherwise you'll be talking with GCP support for your $500 refund -- and yes, that's an unpleasant experience.)
