ChatGPT, steered on purpose
What do you want to do?
On-page practice needs no provider account. Choose a task, read its prerequisite, and start with the supplied cases.
ChatGPT changed a great deal in 2026: one model menu with a Thinking slider, writing blocks in place of canvas, plugins in place of custom GPTs, ChatGPT Work in place of agent mode. This dojo was rebuilt against OpenAI's own pages in October 2026. For people who use it for real work: how to choose how hard it thinks, give it the right context, check what it produced, and hand it longer jobs without handing it your judgment. Every module is a bench of instruments you operate on an invented company's documents, then a field exercise on public or invented material.
Three belts, one habit: decide what it gets, then check what it gives
White belt is the daily conversation: the thinking level, the edit and the branch, the instructions that shape every answer. Brown gives ChatGPT context and tools: memory, Projects, writing blocks, files and data, images, voice, search and connected apps, each with the setting that controls what it keeps. Black hands it longer work: a plugin you built, deep research you audited, a ChatGPT Work task you supervised and a scheduled task that runs inside your plan's limit. Explore in any order; the belt states below say what you have actually done.
