Your practical guide to getting real work out of GPT-5.6 — from picking the right model to handing an agent a goal and getting finished work back. Written for marketers, founders, and creators, not engineers.

On July 9, 2026, OpenAI shipped two things at once: GPT-5.6 (a three-model family — Sol, Terra, Luna) and ChatGPT Work, a Codex-powered agent that takes a goal, works across your apps and files for hours if it needs to, and hands back finished documents, decks, analyses, and sites. This guide is everything worth knowing: what actually changed, which model to reach for, the prompt method that works, 15 copy-paste mega-prompts, and the honest limits so you don't trust it with the wrong thing.
