The workspace layer

Projects means this now.

ChatGPT Project: a workspace with files, project instructions, and a memory mode.
Project instructions override global Custom Instructions inside the workspace.
Choose default memory or project-only memory for the work at hand.
Use a Temporary Chat when you do not want the system to learn from the task.
The solution is not better prompts. It is a better system.

Migration

Already bought an earlier guide?

If you bought Lite or Pro, you already own the philosophy. Global Custom Instructions stay. The charter moves into a real Project file. You are grandfathered into Operator OS.

FAQ

The product boundary.

Why separate Operator OS and the Harness?

Documents and repos do not share an output contract. A ChatGPT workspace guide cannot teach AGENTS.md or hooks.

Will the free GPT-5 playbook replace Operator OS?

No. The playbook is a model map. Operator OS is the workspace install. Paid stays ahead of free, not behind it.
