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,

What You Kill > What You Build
OpenAI killed Sora Not sunsetted. Killed. The product they hyped as the next ChatGPT. The one Disney was about to invest a billion dollars around. The one that was supposed to turn OpenAI into the creative engine of the AI era. Gone in an afternoon. The reason is almost boring in how obvious it is. Sora was eating compute - the most expensive resource on earth right now - while Anthropic was running away with the market tha

I Almost Paid $4,000 a Year to Rent My Own Voice
I almost paid $4,000 a year to rent my own voice back to me. ElevenLabs. $330/month. The model that powers it? Open weights. The inference? Runs on 3GB of RAM. The voice cloning? A 30-second sample and a model you can download for free. The only thing between you and the exact same output is a setup guide nobody bothered to write. So I wrote one. Then I open-sourced it. The gap The gap between what AI costs to run and wha

When to Build vs Buy in AI (My Edition)
I've gotten this wrong before. Not in a small, low-stakes, "oops we picked the wrong software" kind of way. In a way that cost me a year of my life, hundreds of thousands of dollars, and nearly killed a business. So when I tell you the build vs buy question in AI is the most important decision a founder can make right now, I'm not being dramatic. I'm speaking from the scar tissue. The Year I Built What I Should Have Bought

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
