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.

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
