## AI overview

This tutorial describes moving an AI document-processing prototype from a frontier model to cheaper open-weight models through hosted inference providers. It explains how to define a trusted gold set from real project outputs and use workflow-specific evaluation to identify where lower-cost models fail.

## Source excerpt

At Atomic Object, we're encouraged to prototype and dogfood internal projects. Over the last four months, I've been building a prototype to help solve a part of my job that I dislike. The first version used an LLM to extract and classify information from documents, then connect related pieces so humans and agents could retrieve [...] The post How to Move an AI App from a Frontier Model to Open Weights appeared first on Atomic Spin.
