Command Family Text Course

This is a complete text course, free to read in full. All 12 lessons below are published here, in lesson order, and there is no payment, login, or enrolment step for this course.

How this text course is taught

Taught entirely in text. Each lesson is a written lesson with a direct answer first, a worked example shown as text, and questions to answer in writing. Where a diagram would help, the idea is described in words. Where a prompt or template would help, it is shown as text. No lesson in this course requires anything other than reading and writing.

Prerequisites

No specialist background is assumed. You need general reading and writing, and time to work through short written exercises. Earlier lessons in this course are the only preparation for later lessons: start at Lesson 1 and follow the sequence in order.

What you will practise in this text course

By working through the lessons in order, in writing, you will practise how to:

• explain this LLM family in plain written language, without repeating a specification, score, or price;
• write and revise a prompt in text, using a clear task, useful context, and a clear form for the answer;
• check a written output against a source you trust, on a small example, and note where it is uncertain;
• describe limits and safe-use points for this family in writing;
• compare this family with other families in a written comparison based on tasks, access, and what course material demonstrates;
• build a written study plan for continued learning about this family.

These are skills practised in the lessons. Completing this course does not guarantee a job, certificate, or other outcome, and this course does not recommend a specific provider, price, or certificate.
