It's not the size of the model that counts, it's how you use it.

So as developers, we’ve been promised a lot. For about two years now we’ve been hearing some version of the same thing. With AI, you’re gonna actually become a 10x developer. You are gonna get so much more work done than ever before.
Now, I gotta be honest. On my personal projects, oh I feel this. I’m seeing gains that blow way past 10x. But my side projects aren’t exactly representative of the industry. And even within the industry, everyone seems to be getting different results.
I have dev friends in just about every part of it, from the big AI labs, to the Silicon Valley startup that just raised $50M, to enterprise like banks and defense. And what I’ve noticed is just how different their experience with AI is. Some of ’em are seeing only 2x gains, if that. Then you take a look at some others and they ship 2,000 PRs in a real production codebase in a single month.
So I wanted to find out why. Why is there such a big gap in the benefits devs are seeing from AI?
