I spent $3,234.96 on AI last month
|
Hey there, One month. $3,234.96. Every major AI model tested to death. Here's what the receipts actually say. I ran ~3.52 BILLION tokens through these things. Not a typo. And the results surprised even me. The full damage.It was an expensive month, because I actually built something. Anthropic: $1,860.69 • 66% And that was just Cursor, excluding my Codex ($200) and Claude Code ($225) subscriptions. Both of which I've spent 287.8M and 599.6M - an additional 887.4M tokens. But what did I learn? Anthropic is not dead.So here's why I spent $1,860.69 on Claude models this month. Opus 4.7 just came out two weeks ago and while the whole world is shitting on it, I actually like it. It's the type of model that is very creative, mostly follows your instructions, and writes great code. My biggest hot take is that it actually is just as good as GPT 5.5, but only... outside of Claude Code. Think of Claude Opus like the convertible supercar. It's incredibly fun to drive, but it's more expensive, and you wouldn't use it to tow a truck out of the mud. Codex/GPT-5.5 is now the 2nd best app.Second only to Cursor, which still performs better overall (but at a cost). It's the one I reach for the most when I don't use Cursor, and the one I recommend to my non-technical clients. Since it got fast (and more expensive), it has become the #1 AI coding model in the world. But it still sucks at design, which is why I used Claude models so much. Think of it like the SUV of coding models. It's got very expensive too in 5.5, but it's pulling its weight well. Why I don't use other models.Grok 4.20, Gemini 3.1 Pro, GLM 5.1 and Composer-2 make up that 4% share. Honestly, I keep trying. Every few weeks, I'd give them another shot. They're all... fine. GLM 5.1 is actually impressive, and so is Composer-2. But neither can compete with SOTA (state-of-the-art) models we have today. A "fine" status doesn't earn a spot in my stack. What I didn't expect.I thought I'd find one model to rule them all, but I didn't. What I found is that the best builders both SOTA models like a chef uses different knives. You wouldn't use a steak knife to butter your toast. Codex for autonomy and thinking hard. Opus for creative design problems. GLM 5.1 or Composer-2 (or now Kimi K2.5) for when you're on a budget. What this means for you.Stop trying every new model that drops on Twitter. The noise is designed to keep you confused and away from building Use the best two. Learn them well, and actually ship something. Both offer subscriptions, for for $100-200/mo you get the best-in-class. The $3,234.96 was an expensive test for me. But you got the notes for free. Talk next week, P.S. Next month I'm opening some very limited spots to my new AI Architect Program. If you're an established business with a real ideas, thing you want to build, and you need a mix of one-on-one and group coaching support to get it done, this will be for you. Reply "SHIP" and we'll put you on a special launch list. |

Hey Reader, People keep asking me about open source models, especially now with GLM 5.2. But here's how I think about them: If you think hiring a pro is expensive, try an amateur. Sure, they can be cheaper, but I'd never run my business on them. Here's why. What local models get right. First, they're cheap. They sometimes run on your own computer. So you don't have to pay for every question you ask throughout the day. Second, they're also private. Your data never leaves your machine. A local...
Hey Reader, I used to spend 30 minutes to an hour every single day logging into Instagram, Google Analytics, and half a dozen other tools just to see how my business was doing. And I'm literally an engineer with 25+ years of experience. That's 10 hours a week of pure busy work. Here's the exact system I built to get those hours back. You are the bridge. That's the problem. Every morning you log into tool A, look at a number, and carry it in your head to tool B. You're a human bridge between...
Hey Reader, Everyone told you Claude Cowork would make your business 10x more productive. Instead you feel like you have more work than ever. That's not your fault, and I made the same mistake for months. Here's what's actually going wrong. Your AI chats are a broken. You probably have one chat for marketing, one for content, one for random questions. None of them talk to each other. That's like running a business where marketing and sales never meet, and nobody remembers what was decided...
