This hub follows OpenAI Codex and Anthropic's Claude Code side by side, the two terminal coding agents most developers end up choosing between. Instead of one verdict, the articles compare them where the difference shows up in real work.

Start with the model layer. GPT-5.6 vs Claude Fable 5 covers benchmarks, costs and gaps, and GPT-5.6 Ultra vs Max explains what the higher tier actually changes. If you already use Codex, the rate limit guide shows how to stop burning quota, and the power-user tips cover the habits that save the most time. There is also a guide to running GPT-5.6 inside Claude Code for people who want both.

The second group is about workflows that run in either agent. You will find what agent skills are in Claude Code and Codex, a Codex skills guide for reusable workflows, the Gauntlet Loop method in seven steps, pstack setup across Cursor, Claude Code and Codex, and patterns drawn from Gauntlet AI's tool tests. Practical cases include Codex for business automation, an AI second brain built in Codex, and a look at whether leaving the terminal for coding agents is worth it. Beginners can start with the complete Claude Code guide for 2026.
