Appendix A - Acknowledgments

Acknowledgments

This book wouldn’t exist without the generosity of the open-source community.
Thanks to the creators of PyTorch, Hugging Face, FastAI, EleutherAI, and so many others whose work made deep learning accessible.

Special thanks to my friends, colleagues, and readers who encouraged this effort - your feedback helped shape every chapter.

This book was written in collaboration with Claude Opus, GPT-5, and Gemini 3. A book about building AI, built with AI - it would be hypocritical not to. Every idea, decision, and word was reviewed by a human (me), but I'd be lying if I said these models didn't make the book dramatically better. If you're writing a book about the frontier, you should probably use it.
