Right here we go once more. I began one other firm. The cash is within the financial institution.


What’s the tiny corp?

The tiny corp is a pc firm. We promote computer systems for greater than they value to make; I’ve been fascinated with this one for some time. Within the restrict, it’s a chip company, however there’s a number of intermediates alongside the best way.

The human mind has about 20 PFLOPS of compute. I’ve written various blog posts about this. Sadly, 20 PFLOPS of compute just isn’t accessible to most individuals, costing about $1M to purchase or $100/hr to lease.

With the best way AI goes, we threat massive entities controlling the vast majority of the compute on the planet. I don’t want “I feel there’s a world marketplace for perhaps 5 computer systems.” to ever be the world we dwell in.

The purpose of the tiny corp is:
“to commoditize the petaflop”

What’s tinygrad?

I began tinygrad in Oct 2020. It began as a toy challenge to show me about neural networks, it’s now carved out area of interest within the inference area working the mannequin in openpilot, and shortly will probably be a severe competitor to PyTorch in lots of locations.

The primary benefit is within the tinygrad IR. It has 12 operations, all of that are ADD/MUL solely. x[3] is supported, x[y] just isn’t. Matrix multiplies and convolutions are simply multiplies and sums, surrounded by a bunch of zero value motion operations (like reshape, permute, develop).

# a quick matmul in tinygrad (a@b works additionally after all)
from tinygrad.tensor import Tensor
N = 2048; a, b = Tensor.randn(N,N), Tensor.randn(N,N)
c = (a.reshape(N,1,N) * b.permute(1,0).reshape(1,N,N)).sum(axis=2)

tinygrad is lazy, like Haskell, to permit op fusion with out the consumer ever having to consider it.

Okay, so?

The present crop of AI chip corporations failed. A lot of them managed to tape out chips, a few of these chips even labored. However not a single one wrote an honest framework to make use of these chips. That they had related efficiency/$ to NVIDIA, and method worse software program. In fact they failed. Everybody simply purchased stuff from NVIDIA.

I feel the one strategy to begin an AI chip firm is to start out with the software program. The computing in ML just isn’t normal objective computing. 95% of fashions in use at this time (together with LLMs and picture technology) have all their compute and reminiscence accesses statically computable.

Sadly, this benefit is thrown away the minute you might have one thing like CUDA in your stack. As soon as you’re calling in to Turing full kernels, you’ll be able to no longer reason about their conduct. You fall again to caching, warp scheduling, and department prediction.

tinygrad is a straightforward framework with a PyTorch like frontend that may take you all the best way to the {hardware}, with out permitting horrible Turing completeness to creep in.

The Pink Group (AMD)

10 or so corporations thought it was a good suggestion to tape out chips. Sarcastically, taping out the chip is the simple half. It requires a number of capital, however that simply includes convincing silly traders that the area they’re focusing on is SO HUGE that even when they’ve a 3% probability of success it’s price investing. Traders fall for this, they make investments, and the world tapes out ineffective AI chips.

There’s a great chip already in the marketplace. For $999, you get a 123 TFLOP card with 24 GB of 960 GB/s RAM. That is the perfect FLOPS per greenback at this time, and but…no person in ML makes use of it.

I promise it’s higher than the chip you taped out! It has 58B transistors on TSMC N5, and it’s just like the twentieth technology chip made by the corporate, third on this collection. Why are you so conceited that you just assume you may make a greater chip? After which, if nobody makes use of this one, why would they use yours?

So why does nobody use it?

The software program is horrible! There’s kernel panics within the driver. You must run a more moderen kernel than the Ubuntu default to make it remotely secure. I’m nonetheless undecided if the motive force helps placing two playing cards in a single machine, or if there’s some poorly written international state. Once I put the second card in and run an OpenCL program, half the time it kernel panics and it’s important to reboot.

That’s the kernel area, the consumer area isn’t higher. The compiler is so unhealthy that clpeak solely will get half the max potential FLOPS. And clpeak is a very contrived workload making an attempt to maximise FLOPS, by no means thoughts what number of FLOPS you get on an actual program (normally like 25%).

The software program known as ROCm, it’s open supply, and supposedly it really works with PyTorch. Although I’ve tried 3 instances within the final couple years to construct it, and each time it didn’t construct out of the field, I struggled to repair it, acquired it constructed, and it both segfaulted or returned the flawed reply. Compared, I’ve most likely constructed CUDA PyTorch 10 instances and by no means had a single situation.

The place does the tiny corp are available?

Overlook all that software program. The RDNA3 Instruction Set is properly documented. The {hardware} is nice. We’re going to write our personal software program.

If you happen to had been to tape out your individual chip, you’d be scuffling with each {hardware} bugs and software program bugs, and also you wouldn’t make certain which one it’s. Right here, you might have a good suggestion, and have the AMD supplied driver as an open supply reference.

That is life on simple mode, and I nonetheless doubt any of these AI startups might have achieved it. That is what the tiny corp goes to do to start out. Construct a framework, runtime, and driver for AMD chips.

AMD on MLPerf

Each couple months, MLCommons hosts MLPerf, a contest to coach a standard set of fashions quick. AMD has by no means been on the checklist, not as a result of the {hardware} can’t do it, however as a result of the software program can’t. The checklist is dominated by NVIDIA, however Google TPUs, Intel CPUs, Intel Habana, Huawei Ascend, and Graphcore IPU have made appearances. By no means seen AMD.

Our quick time period purpose is to get AMD on MLPerf utilizing the tinygrad framework.

However how do you make cash doing that?

We don’t. We raised $5M from a tremendous set of traders who’re aligned with actual worth creation.

We make cash promoting computer systems for greater than they value to make. (preorder a tinybox at this time)

If we succeed at this challenge, we will probably be on the slicing fringe of non NVIDIA AI compute. We now have the power to make the software program, and that’s the exhausting half. Comparatively, taping out chips is straightforward. If we actually have a 3% probability of dethroning NVIDIA and consuming in to their 80% margins, we will probably be very very wealthy.

How can I assist?

We’re hiring software program engineers to work on tinygrad. In particular person in San Diego, on the lookout for individuals who need to work exhausting and construct one thing unimaginable. Come work on an open supply challenge that, if achieved proper, will play a job within the joint future of humanity and its machines.

I don’t need to dwell in a world of closed AI working in a cloud you’ve by no means seen, I would like everybody to have an AI that they personal, each coaching and inference. I would like compute to be obtainable from 50 totally different corporations all competing to drive the worth to zero. And I would like an open supply framework to run innovative AI on any a kind of 50 chips as seamlessly as Linux helps 50 community playing cards.

If Elon has the FSD Chip and Dojo for Autopilot and Tesla’s robots, now we have the tiny corp for openpilot and comma’s robots. comma, together with 100s of different corporations, will want computer systems each massive and small for coaching and inference. We are going to promote them these computer systems. If NVIDIA is the Apple, we’re the Android.

E-mail george@tinygrad.org to use and I’ll ship you the programming problem. If you happen to really feel such as you missed the start of comma, get in on this. The enjoyable of the start is how a lot you get to form.
