The Hands-On Guide to Open-Source AI

Every hour you spend on Midjourney or DALL-E costs you money. This book shows you how to stop paying.

Using nothing but your own computer, you'll install two free, open-source AI models - flux2-klein and qwen3.5 - running locally through Ollama. No subscription. No per-image fee. Just your electricity bill.

This is not a theory book. It's a hands-on build, chapter by chapter: install the tools, generate your first image, master the parameters that control quality and reproducibility, write prompts that actually work, and turn a single line of Korean into a finished, sellable image. Then you go further, using Claude chat and Claude Code to automate the entire pipeline, so one command handles translation, generation, and saving in a single step.

The flux2-klein:4b model used throughout this book is released under the Apache 2.0 license, which permits commercial use, so the images you generate here can legally be sold. The final chapters walk you through exactly how: preparing commercial-quality images, meeting platform requirements, and listing your first icon pack on Etsy, from account setup to your first sale.

What you'll learn:

• Installing and running Ollama, flux2-klein, and qwen3.5 locally, for free
• Controlling resolution, quality, and reproducibility with Ollama's generation parameters
• Writing prompts that produce consistent, high-quality results
• Automating the Korean-to-image pipeline with Claude Code
• Meeting commercial licensing requirements and platform quality standards
• Listing and selling icon packs on Etsy, step by step

This book is for anyone with a day job who wants to build a side income in the evenings, anyone curious about AI who doesn't know where to start, and anyone who would rather learn by building a real pipeline than by reading theory. No prior AI or coding experience is required - every step is one you follow along and do yourself.
