Building and training fully functional Decoder-Only transformer](https://www.securitynik.com/2026/03/welcome-to-world-of-ai-putting-it-all.html) _2026-03-07 · Nik Alleyne, MSc | CISSP | GC|IA|IH|REM|PEN · Learning by practicing_ In the first post, we learned about temperature, top\_k and top\_p. We then built a Decoder-Only Transformer using pure NumPy in the second post. The third post we took advantage of PyTorch. In this final post, we put the raw code needed to run a full decoder only transformer, to generate baby names. Hope you enjoyed this series. As always, if you think there is something I should have done… ## [Welcome to the world of AI - Learning about the Decoder-Only transformer - From scratch with PyTorch](https://www.securitynik.com/2026/03/welcome-to-world-of-ai-learning-about_7.html) _2026-03-07 · Nik Alleyne, MSc | CISSP | GC|IA|IH|REM|PEN · Learning by practicing_ In this third in this series post, we build on what we did in the previous post to now build GPT from scratch. We will leverage Andrej Karpathy Makemore series . Where as Andrej used Tiny Shakespeare, we will use the baby names dataset that he used in one of his earlier trainings Import the libraries import torch import torch.nn as nn import torch.nn.functional as F import matplotlib.pyplot as plt… ## [Welcome to the world of AI - Learning about the Decoder-Only Transformer - From scratch with NumPy](https://www.securitynik.com/2026/03/welcome-to-world-of-ai-learning-about.html) _2026-03-07 · Nik Alleyne, MSc | CISSP | GC|IA|IH|REM|PEN · Learning by practicing_ In this post, we build a \*\* Decoder-Only Transformer \*\* from scratch, using \*\* only numpy \*\*. I wanted to put this together to see if I can find an easier way to build this very popular architecture, while at the same time, seeing if it helps someone else. As you go through, if you find I missed anything or have some suggestions for improvement, please do not hesitate to drop me a line. As we go… ## [Welcome to the world of AI - Understanding temperature, top\_p and top\_k](https://www.securitynik.com/2026/03/welcome-to-world-of-ai-understanding.html) _2026-03-07 · Nik Alleyne, MSc | CISSP | GC|IA|IH|REM|PEN · Learning by practicing_ This post is part of a 4 part series on learning and building a decoder-only transformer from scratch. This is the first post that focuses on learning about \*\*temperature\*\*, \*\*top\_p\*\* and \*\*top\_k\*\* as they are used in language models. Without further ado, let's move ahead. # import the libraries. import numpy as np import matplotlib.pyplot as plt from scipy.special import softmax # Let get our… ## [CTF: Silence of the RAM - Tushar's Write-up](https://www.securitynik.com/2026/01/ctf-silence-of-ram-tushars-write-up.html) _2026-01-28 · Nik Alleyne, MSc | CISSP | GC|IA|IH|REM|PEN · Learning by practicing_ BIG shout out and thanks to Tushar Arora for putting this together for our SOC team.
