What I'm thinking about right now.

Why I chose Unsloth (before training a single token)
Honest note up front: I have not yet fine-tuned anything with Unsloth. I have not run a single training job. What I did is spend three weeks researching fine-tuning frameworks before writing a line of training code — and at the end of that research, I picked Unsloth and committed to it. This post is about why. I'm writing it now, before I start, for two reasons. First, so that if this decision ages badly I have to own it public

Why I'm fine-tuning a small model (and why it runs on your laptop)
I'm training an AI model. It's going to run on a laptop. Three weeks ago I would have told you I was training a 70-billion-parameter model, the kind of thing that needs a data center to breathe. I'm not. I'm training a 4-billion-parameter model that runs on a Mac Mini. If the smaller one works, a larger companion model may follow. But the 4B is the bet. This is the first post in a series where I'll share what I'm building, why,

How 0% APR Credit Cards Actually Work — From the Other Side of the Desk
A few years ago I was working with a homeowner in Tennessee who needed $35,000 for a renovation project. He had one requirement: 0% APR. Wouldn't consider anything else. We found him a card with a 21-month intro period at 0%. Best terms on the market. He applied, got approved — for $20,000. Not $35,000. Twenty. Now he's got a $15,000 gap and no plan for it. But that wasn't even the real problem. The real problem was that the ca

How We Picked Our Open-Source AI Model (And Why We Didn't Pick the "Best" One)
TL;DR: * There are dozens of open-source AI models and new ones drop weekly. * Most comparison guides are benchmark tables that mean nothing to business leaders. * Here's how we actually chose — why we went with a smaller, "less impressive" model over the flashy options, and why that turned out to be the right call. In my last post, I wrote about self-hosting our own AI for $700 a month. A lot of people asked the same follow-

I'm Starting to Write About Money
I'm starting to write about money. Not affiliate-stuffed credit card listicles dressed up as advice. Not "the one weird trick your bank doesn't want you to know." I mean how the system actually works from the inside. What I do with my own money. The math nobody shows you because it's boring and doesn't sell a course. This is the personal finance layer of Own or Be Owned — understanding the machinery well enough that it works
