Build Your Own AI

Build Your Own AI is a comprehensive educational resource designed specifically for developers who want to build practical AI applications using large language models. The book provides structured, framework-free guidance on implementing LLMs without requiring knowledge of specific programming languages, using clean TypeScript examples that can be adapted to any development environment. It covers everything from basic terminology to advanced concepts like running models locally, prompt engineering, and data extraction techniques.

The standout feature of Build Your Own AI is its practical, language-agnostic approach. Unlike many resources that focus on Python-specific implementations, this guide uses straightforward TypeScript without frameworks or libraries, focusing on core concepts and HTTP requests. This makes the knowledge immediately applicable regardless of your preferred programming language. The book systematically covers Retrieval-Augmented Generation (RAG), tool calling, agent development, and even provides a sneak peek into fine-tuning approaches.

This resource benefits developers at all levels—from absolute beginners to those with some existing AI knowledge—who want to understand how to work with LLMs in real-world applications. It's particularly valuable for developers who want to build AI solutions with enhanced privacy by running models locally, or those looking to implement advanced features like document retrieval systems and custom tools without getting bogged down in framework-specific complexities.
