Codex Guide Tops JD.com's Daily Bestseller Chart on Day One

My new book has reached the top of JD.com's bestseller list!

This is Cang He's 616th original post!

Hello everyone, I am Cang He.

I want to share some good news with you: my first paper book, "Codex: From Beginner to Master," has reached #1 on JD.com's daily book sales chart.

Besides being #1 in the "Tech New Trends" section of the bestseller list, it also topped the "New Book Bestseller" list in the Tech New Trends category.

I'm so surprised and grateful for everyone's support.

I've also set up a lottery at the end of the post to give away a few copies to friends, to thank you for your ongoing support. You can also leave a comment below.

It was just released yesterday, and many good friends helped promote it on their social feeds. I'm truly moved, thank you.

Some screenshots weren't captured, but I remember everyone in my heart 🙏

Some friends also helped promote the book in their own communities. For a moment, it seemed like many AI communities were flooded with posts about it. I feel a bit ashamed for taking up everyone's time.

On X, many big names and friends also helped promote the book. I'm very grateful.

I also want to thank the fans who placed orders. I see every single order and hold it in my heart.

To be honest, I was nervous before the release.

After all, it's my first paper book. I revised it over and over, worried that something wasn't clear enough and would waste readers' time.

But the moment it went live yesterday, my backend and private messages were flooded with screenshots of purchases.

Some friends bought several copies at once, saying they wanted to give one to each member of their team.

Some friends said they hadn't used Codex much, and this book was a good chance to learn it systematically.

Many long-time followers commented that they've been with me from reading my WeChat articles to buying my book, walking this path together.

Even some overseas friends said it's hard to buy the paper book and asked for an electronic version.

Honestly, seeing these messages made me a bit teary-eyed.

I've been writing this WeChat public account for so many years; every article was written for you all reading on the other side of the screen.

This time, you brought my book home with real money. That trust is heavy.

So I want to make a promise here.

If anything in the book is unclear, or you run into any pitfalls during practice, feel free to reach out to me.

As Codex evolves with new features and updates, I'll continue to share them on my WeChat account and the CodexGuide website. This book won't become outdated after you buy it.

Thanks to Kazike, AJ, Jiamu, Kangaroo Di, Liu Cong, and MoYu XiaoLi for writing endorsements despite their busy schedules.

Everyone is usually swamped, yet they still took time to read the manuscript and write thoughtful recommendations. I appreciate that friendship deeply.

Receiving recognition from so many good friends in the AI circle is a huge encouragement to a first-time author like me.

Finally, I want to thank Teacher Jia Jing from Posts & Telecom Press, and all the editors, typesetters, proofreaders, and designers who worked on the book, as well as the friends who participated in revisions.

From topic selection, refining the manuscript, to final printing and listing, every step relied on everyone's professionalism and patience.

Especially Teacher Jia Jing, who accompanied me through revisions and nitty-gritty details. As a novice author, I caused her no small amount of trouble.

For a book to successfully reach readers, a whole team is quietly supporting it from behind. Thank you all sincerely.

In fact, last year, several publishers approached me about writing a book, but I hadn't made up my mind then. I turned down offers on DeepSeek, openclaw, and several other topics.

I thought AI technology was advancing too quickly. Publishing an outdated book would just be wasting readers' money and time.

The features might change before the book even gets printed.

But Codex is different. I've been using it since the early versions and am among the early batch of users. That's why I also set up a website, codexguide.ai.

It updates a lot of use cases and examples for Codex. So I have a bit of confidence that the "technique-level" stuff in the book might expire, but the "principle-level" stuff won't.

For example, how to use Codex to build workflows and skills. The book's companion website stays constantly updated.

I've also always liked Codex as a product. Even though GPT model consumption has gotten faster and it sometimes seems dumber, Codex remains my primary tool. Its harness capability is genuinely excellent.

I also hope to keep sharing new ways to use Codex with everyone.

Additionally, I want to donate the royalties from this book to children with visual impairments. The amount is still small, but I really hope they can all have a bright future.

Finally, thank you all for your support. If you also like Codex or want to learn it, please take a look at this book.

I'll draw a few copies to give away for free. Thank you all for your support.
