Монументальный пост от моего друга - From App Factories to a Reasoning Compiler

I didn’t plan to build a compiler — I just wanted to maximize out of the AI agents I had.

What is an AI agent today? It’s actually quite simple. There is a language model — the brain and the center of decision making. And there is a harness around the model: the environment where the model works — the thing that makes the model an agent. Without the harness the model is just a text generator, sometimes quite a smart one.

Most of the resources of the labs around the world go into improving the models, which we use as is — and thank god, it’s not us who pay for their training. The harness gets much less attention from the research community. So I have good news for you: the harness is exactly the place where an indie researcher can make a contribution, without having the resources of the frontier labs.
