Build LLM From Scratch is the ambitious, practical learning experience detailed in a May 7, 2026, Hackaday article by Al Williams. This initiative offers a hands-on workshop focused on constructing a bare-bones Large Language Model (LLM), providing a tangible understanding of AI’s foundational elements.
Drawing inspiration from nanoGPT, this project scales down the complexity, enabling users to train a functional LLM in approximately one hour on a typical computer. This accessibility is crucial in demystifying AI development, making it approachable for a broader audience beyond specialized researchers.
The Practical Path to AI Understanding
The workshop is meticulously structured into six core parts: beginning with the tokenizer, progressing through the transformer, the training loop, and text generation. It culminates in model training and even an engaging section dedicated to identifying the ‘best AI poet.’ This comprehensive approach ensures participants grasp each component’s role in the LLM’s overall functionality. Supporting this, a robust references section provides access to relevant academic papers, encouraging deeper exploration.
Participants require a Mac, Linux, or Windows PC running Python and common libraries such as numpy and torch. For those with enhanced hardware, the workshop can optionally leverage an Apple or NVIDIA GPU, significantly speeding up the training process. This flexibility ensures a wide range of users can engage with the material.
“Learning from first principles is paramount; reading about bowling isn’t the same as actually bowling – the same applies to building an LLM.”
Build LLM From Scratch: A Response to Growing Demand
This ‘LLM From Scratch’ project emerges as a timely response to the surging interest in understanding and constructing AI models. With the increasing availability of open-source AI tools, there’s a palpable desire among users to gain more control and insight into their LLMs. This workshop directly addresses that need, empowering individuals to move beyond mere consumption of AI tools to active creation.
The project’s philosophy emphasizes learning from foundational concepts, going so far as to suggest that an LLM could even be constructed using a spreadsheet for those less inclined towards Python. This creative problem-solving highlights the core principles of LLM architecture, independent of specific programming languages. It’s a testament to the idea that fundamental understanding transcends tool-specific knowledge.
Broader Implications for AI Accessibility
The ‘LLM From Scratch’ initiative is not an isolated effort. It aligns with other discussions and projects on Hackaday, which have explored similar themes, such as building LLMs in pure C, creating hackable ChatGPT clones for around $100, and critically examining the implications of LLMs being installed on personal machines without explicit user consent. These parallel discussions underscore a growing movement towards open, transparent, and user-controlled AI development within the tech community.
This hands-on approach to building AI models represents a significant step towards democratizing AI knowledge and fostering innovation from the ground up. By enabling individuals to build LLM from scratch, the project not only educates but also inspires a new generation of AI developers and critical thinkers. This practical engagement is crucial for navigating the evolving landscape of artificial intelligence and ensuring its responsible development.
