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,

Announcing Ghost Narrator: Self-Hosted AI Narration Stack
We publish about 200 blog posts a month on Founder Reality. Every post gets a narrated audio version — you can listen instead of read. The obvious solution was ElevenLabs. Best-in-class voice cloning, simple API, great output. $330/month for the scale we needed. We almost signed up. Then we tried something else. We ran an open-source model on a laptop. Qwen 3.5 14B for script rewriting, Qwen TTS for voice cloning. The whole pi

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

The Freedom Number Isn't What You Think
Stop calculating your "retirement number." Everyone obsesses over how much they need saved to never work again. $1M? $2.5M? $5M? You're asking the wrong question. The right question: How much cash flow do I need to own to say no to anything? The answer is probably 80% smaller than your retirement number—and achievable 30 years sooner. The Wrong Calculation (That Everyone Does) The traditional retirement framework: "How muc

You Cannot Buy What Can Only Be Built
Meta spent $14.3 billion last year to buy half of a data labeling company. They made its 28-year-old CEO the head of their Superintelligence Lab. Gave him a title that didn't exist six months before. Put him above researchers who'd been doing AI before he was in high school. Nine months later, his team reports to other people. A new group controls the data pipelines. The researchers he was supposed to lead are leaving. And the
