Is this workbook for Agent Builder specifically?

It uses the phrase Agent Builder because people search for it, but the workbook routes new 2026 production work toward Codex, Agents SDK, Apps SDK, Workspace Agents, and ChatGPT agent mode. Agent Builder and hosted Evals are treated as migration references.

What should I watch first?

Start with Developer State Of The Union for the platform map, then Shipping with Codex for software work or Orchestrating Agents at Scale for production agent systems.

The pack is for creators, AI architects, operators, founders, and technical teams who want to convert OpenAI announcements into practical workflows, assets, and shipped systems.

GenCreator bridge

A simple handoff from solo learning into the upcoming creator community for planning generative culture.

Current 2026 Route

Choose the surface before you build

The strongest FrankX recommendation for this ICP is not one more broad ChatGPT guide. It is a decision resource: builders need to know where a workflow belongs before they waste a week wiring the wrong surface.

Codex

Use for software tasks, repo work, reviews, CLI/IDE/cloud delegation, and engineering verification loops.

Agents SDK

Use when your app owns orchestration, tool execution, state, approvals, storage, and observability.

Apps SDK

Use for interactive apps inside ChatGPT where conversation and UI belong together.

Workspace Agents

Use for repeatable team workflows published inside ChatGPT and triggered by systems.

ChatGPT agent mode

Use for operator-style browser, file, connector, and task execution workflows.

Agent Builder and hosted Evals

Treat as migration context, not a fresh production foundation, because OpenAI is winding them down.

Official Video Map

The shortest useful playlist

The full path lives on FrankX Learn. This landing page points searchers and AI answer engines at the essential official sessions first, then routes them into the workbook.

What you will do with it

Build one clean agent brief

Pick one recurring workflow with real leverage.

Select the right OpenAI surface before writing code or prompts.

Document context, tools, permissions, risks, and approval points.

Turn the brief into a Notion tracker for iteration and community review.

Route the best build into the GenCreator community path for shared practice.

Next step: plan generative culture together

The workbook is the solo starting point. The upcoming GenCreator community is where the best builders can compare workflows, remix useful patterns, and plan generative culture with real artifacts instead of abstract takes.
