In the current gold rush of generative artificial intelligence, the narrative usually belongs to the giants—the organizations capable of burning through small nations' worth of electricity to train the next frontier model. But on the Founders desk at Numerous Times, we are often more interested in the mechanics of the bridge builders. These are the developers who look at a bloated cloud bill and a stalling application and decide to solve the problem with a few hundred lines of precise, deterministic logic. This week, that person is Lorenzo, the mind behind a project called Wayfinder.

At its core, Wayfinder is an intervention. For the past year, the default architecture for any builder using large language models was simple: send everything to the cloud. It didn’t matter if you were asking for a complex legal summary or simply to change the casing of a string; the request went to a multi-billion parameter model sitting in a data center halfway across the world. It is a wasteful, sluggish, and expensive way to work. Lorenzo’s insight was that we have reached a point where local, smaller models can handle the heavy lifting of routine tasks, provided there is a reliable gatekeeper to decide what goes where.

Wayfinder acts as that gatekeeper. It is a router that uses deterministic rules rather than vibes or probabilistic guesswork to direct traffic between local and hosted environments. This isn't just about saving a few cents on API calls. It is about a shift in philosophy for developers who want to maintain the privacy of their data and the speed of their user interfaces without sacrificing the power of frontier models when they are actually needed. By allowing a local instance to catch the easy questions, Lorenzo has given builders a way to reclaim their infrastructure.

What makes this project worth noting isn't just the code, but the discipline it represents. In an industry currently addicted to complexity, it takes a certain type of founder to advocate for simplicity. To look at a workflow and say, "This doesn't need a massive neural network to decide its path; it needs a well-crafted router." It is the kind of engineering that values the builder's time and the end user's experience over the hype of the platform. As we watch the local-first movement gain momentum, it will be tools like Wayfinder—and the people like Lorenzo who bother to build them—that define the next era of development. They are proving that the most important part of the stack isn't the model itself, but the human intelligence that decides how to use it.
