Back to ChannelI Asked GPT-5 to Rebuild My 100K Line App. Its First Move Changed Everything.
I expected it to start coding. Instead, it stopped, studied the entire application, and made a decision I've only ever seen experienced architects make. Six hours later, 150 files had changed — and...
GPT-5.4 Got the Best Score I've Ever Seen — Then I Found Something Stranger
GPT-5.4 scored 95% on my planning benchmark — the highest I've ever recorded. But while I was testing it across every tool I use, a pattern showed up in the data that I genuinely did not expect. An...
My Biggest AI Unlock — It Does Everything

The One Shift That Takes You to Level 3 With AI
I spent a year figuring out why AI worked brilliantly sometimes and felt completely useless other times. Turns out the answer had nothing to do with the tools. Most people using AI right now are s...
Something Is Happening Inside Claude Code Agent Teams
I designed every agent. I understand the architecture. And the output still surprised me — not because it was good, but because I can't trace how it got there. I built an ideation system using Cla...
You're Throwing Away Your Best Thinking Before AI Sees It
Every time you type a prompt, you edit it first. You compress your thought down to the short version — and the part that actually matters never makes it in. There's a fix, and every AI company on t...
Codex Spark's Real Value Isn't Coding — Here's What It Is
I spent an hour using Codex Spark before I read a single thing about it. That hour told me more than any benchmark chart could. OpenAI just shipped Codex Spark — a smaller variant of GPT-5.3 Codex...

I Built the Same App 9 Times—The Results Made No Sense
I thought GPT-5 Pro would crush the cheaper models. 15 minutes vs 15 seconds to generate a PRD—there had to be a difference. Then I built the same app 9 times and discovered something I wasn't expe...
Claude Code's Chrome Extension Does Way More Than You Think
Most people think this is just another AI browser sidebar. I thought the same thing until I saw what it could do with Claude Code. The Claude team quietly shipped a Chrome extension that does far ...
You're Not Crazy. AI Really Does Ignore You.
You tell it something important. It nods, gets to work, and five minutes later—does exactly what you told it not to do. Then it apologizes. Promises to do better. And five minutes after that? Same ...
Claude Code: This Skill Is No Longer Optional
This isn't about becoming a programmer. It's about developing the skill that will matter for everything. The gulf between people who understand these tools and people who don't is widening fast. A...
Vibe Coding: From Party Trick to Real Tool
