### AI overview

This guide explains how to isolate Codex in a headless Ubuntu virtual machine running on Proxmox, using a separate Linux account and OpenSSH. The setup limits the files, dependencies, and network access available to the agent while keeping administrator tasks separate, but it does not eliminate risks from credentials, network access, or mistakes pushed to GitHub.

### Source excerpt

The more useful coding agents become, the more access they tend to need. Installing dependencies, running commands, changing files, and generally more autonomy are part of the appeal. They're also the point where I start thinking about what else the coding agent can reach, especially while these tools are changing so quickly. My answer is [...] The post Your Coding Agent Should be in Jail. Here's Why and How. appeared first on Atomic Spin.

### 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.
