Hi all, I have a new result I'm excited to share. It turns out that *all existing implementations* of softmax and cross-entropy (that's JAX, PyTorch, textbooks, etc) have a subtle bug --- two bugs, actually. A simple rewrite fixes both, and eliminates "slingshots" when grokking:

After AlphaGo, the skill of human Go players noticeably improved. I suspect we will see a similar pattern in math.
Does AI recommend AI over humans?
Should you invest in Bitcoin or stocks?
Does it favor some people, products, or ideas over others?
You can’t answer that from one prompt.
We used 1M+ test questions to study systematic shifts in model behavior.

🚀We’ve raised a $7.5M seed, backed by an amazing group of angel founders.
We’re rethinking how LLMs work — efficiency first, far beyond chatbots. Shipping our first product Pulse, built on CAP-1.

Beautiful technical debugging detective longread that starts with a suspicious loss curve and ends all the way in the Objective-C++ depths of PyTorch MPS backend of addcmul_ that silently fails on non-contiguous output tensors. I wonder how long before an LLM can do all of this.

🇪🇺 As a European citizen and AI founder, I can apparently use these "AI Factories", so I just signed up to use them!
Every "supercomputer" has an [ ACCESS NOW ] button which made me very excited
I expected to sign up, maybe pay a discounted H100 rate (funded by EU, that'd be nice?) and get a Jypyter notebook, or some SSH login so I can access my GPU like I'd do on @lambdaapi or @awscloud or @Hetzner_Online
But I celebrated to early, I signed up, confirmed my email, then ended up in a "Supercomputer Access Calls" page, where I had to select from a tedious list of "Call For Proposals" to get access to a GPU
So I could NOT just access a H100 GPU, I have to make sure my project (in this case my business) fits a specific proposal, ok fair
This process was already tedious enough but then when I tried to actually go through with it, it started asking me if I had "Respect for Human Agency?", I do I think, and if I was mindful of "Individual, and Social and Environmental Well-Being?", well I am, right guys??? Right??? The questions didn't stop, just endless pages of this
Look I get what they're doing, they pivoted the classic university "I need to rent a giant computer for my research" to an EU wide thing and then present it as the "European AI plan"
But this isn't really how AI works in production? As a founder in AI, if I wanna do stuff I'd rent a whole bunch H100 GPUs again at @lambdaapi or @awscloud or @Hetzner_Online and SSH into a box
Or if I want it more simple I run AI models on @FAL, @wavespeed or @replicate which is just an API call or web front end I can click stuff and run a model
The EU has the right intentions here but it's just the wrong execution, this thing will 100% go nowhere, and I'm a born optimist, I want to believe, I'm also a proud European, and I'm in AI a bit and not a complete idiot. There's just better ways to do this
If you really want to have the GPU servers in Europe (which arguably isn't that important), then let me rent a GPU box with SSH access at @Hetzner_Online or @OVHcloud that's hosted in Europe and subsidize that for European citizens and European businesses. I don't even believe in that, but at least that'd make it accessible for Europeans. Now it really isn't?
What's REALLY much more important though if you want to be a part of the AI race and I've posted for years here with @euaccofficial is to make Europe a really extremely attractive place to start and run an AI business. Remove regulatory obstructions and give tax discounts for startups. Let them build a business first that can compete worldwide and once they make enough money (let's say $100M/y), then slowly start adding regulation. Because right now the regulation only benefits the European incumbents, the dinosaur companies, while making it very difficult for European citizens to start new AI companies here.
Which is why we literally have none left.
Anyway, I applied to get my GPU, let's see if I get it!
What in the F is an AI factory?
I had to investigate what the unelected @EU_Commission is talking about today
So according to them, it's some data centers (which they call supercomputers) in 6 different EU countries
I checked out the most powerful one: Karolina, a Czech data center, it mostly has CPUs though (see pic) not GPUs, so mostly useless for AI
The GPUs it does have are 72x 8x NVIDIA A100 GPU, so 576x A100, or equivalent of 240x H100s
(H100 is about 2.4x the compute power of A100)
So let's compare that:
@xAI has 200,000x H100 GPUs
So the xAI data center has 800x more compute than the Czech one
If we combine xAI, Meta, AWS, etc. it's about 750,000 H100s
If we assume the other 5 data centers in the EU are equivalent to the Czech one (which is massive stretch because most of the others seem AI consultacny services, they don't even HAVE chips!), the EU's new "AI factories" have a total of 1,440x H100 GPUs, let's round up to 1,500 to be nice
So the EU is trying to compete with 750,000 GPUs with their own 1,500 GPUs, so 500x less??
Correct me if I'm wrong but it's just seems very low impact and another ridiculous idea and burning of EU tax payers money that will end up in local cronies and bureaucrats and will do NOTHING to improve the AI business climate for Europe
The best way to improve it is to deregulate, make it super easy and low tax (especially when starting out) to start AI companies in Europe
I’ve been working on language models for years, and one thing is clear: we can do a lot better than just scaling GPUs.
This challenge is about bold new ideas — can’t wait to see what people come up with.
At BottleCapAI, we believe AI shouldn’t cost tens of millions to train.
We are now opening challenge for those who want to help with that!
