Frontier Subscription

Some of the leading AI companies have partnered with me to bring AI by Hand ✍️ to their engineering teams. They wanted a way to see and understand the math behind the complex Frontier AI architectures and algorithms they’re implementing. Through clear Worksheets and Blueprints, I help them verify that every algorithm is mathematically sound—and reveal where real optimization opportunities lie.

When engineers can see the math by hand ✍️, they don’t just build faster—they build smarter.

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

• Break open the black box of frontier AI models

• Build deep mathematical intuition

• Bridge the gap between code and math

• Stay ahead of cutting-edge research as it happens

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

Here’s an overview of the first 12 issues of my Frontier Worksheets:

1. “Expert Choice” Mixture of Experts (MoE)

2. New GPT-OSS Trick to Ignore Tokens

3. MHA, MQA, GQA, MoE-A: More Attention!

4. MXFP4, FP4, FP8

5. LoRA, Fine-Tune, Pre-Train

6. QLoRA, DoRA, BitFit, NF4 vs INT4

7. KV Cache, Prefill, Decode

8. EmbeddingGemma, MRL, InfoNCE, Embed vs. Decode

9. Inference Batching, Request-vs-Token Level

10. MLP Parallelism: Data, Context, Row, Column, Pipeline

11. RoPE vs PE in QKV Self-Attention

12. RMS, Group, Layer, Batch Norm, Tensor Parallelism

First 12 issues of the AI by Hand ✍️ Frontier Subscription (100+ new worksheets).

Here are 3 recent issues of my Frontier Blueprints:

• DeepSeek Attention

• DeepSeek OCR

• LinearLayer+LoRA Blueprint: PyTorch, BLAS, CUDA

👉 For $50/month, the Frontier subscription gives you my newest Worksheets and Blueprints about Frontier models and algorithms.

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 and blueprints 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.

💡 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!
