🔥 New: Frontier Subscription

Frontier Model Math by hand ✍️

Major AI companies reached out to me. They wanted access to my latest AI by Hand ✍️ worksheets because they know that unlocking the math inside the “black box” gives their AI engineers an edge over the competition and drives the future of AI.

Initially, I told them to wait a few months until I compiled everything into a book.
But they said, “We can’t wait—we want this content now.”

So they buy licenses to regularly distribute my newest AI by Hand ✍️ worksheets to their employees as soon as I’ve created them.

Now, for the first time, you can get the same immediate access. Each week, you’ll receive my newest worksheets, the exact ones these companies license for their teams, helping you:

• Break open the black box of frontier AI models

• Build deep mathematical intuition

• Stay ahead of cutting-edge research as it happens

You no longer have to wait months for my next book to be published.

👉 For $50/month, the Frontier subscription gives you my newest worksheets as I create them — the same materials my graduate students use and top AI companies license to access..

To Individual AI Engineers:

I want to thank you for becoming Frontier subscribers — you motivated me to prioritize my time and energy to this challenging task: making worksheets that explain the math and algorithms behind frontier models. Otherwise I probably would need to spend my time doing other busy works.

To AI Startups:

I am glad that with the Frontier subscription through Substack, small AI startups like yours can simply buy a group subscription — rather than negotiating a licensing deal with me (or my university). That means your engineers can begin understanding frontier models immediately, keeping up with the most current trends to gain a competitive edge over others.

And for a limited time, you’ll also receive a free ebook copy of my 250+ page Matrix Multiplication Workbook ($30) when you join.

💡 Pro tip: Get reimbursed

Most subscribers don’t pay themselves—companies cover it. Frontier fits right into your professional development budget, and it’s cheaper than a single training course. Just ask.

📧 Template email to your manager/HR:

Hi [Manager’s Name],

I’d like to subscribe to the AI by Hand ✍️ Frontier ($50/month). It’s the same training materials licensed by leading AI companies, and it will help me build deeper intuition for frontier AI models.

Can we expense this under our training/professional development budget?

Thanks!
