Prompting Basics for the Yi Family
A beginner should approach prompting for the Yi Family by giving a clear task, useful context, and a clear form for the answer, then checking the result. This guide explains that pattern and how to improve a prompt in small steps. This lesson centres on building a prompt from task, context, and answer form, with the Yi Family as its example: a bilingual open-weight family, so checking course claims against the family's own documentation is the habit to practise.
Dated snapshot note: Treat this guide as a general description as of 31 October 2026. Model details change often, so check current official documentation before relying on a specific version, feature, price, or limit. No model specification, price, or benchmark score appears here, because those details age quickly and are easy to misstate.
## Lesson 4 of 12 in this text courseLesson 4 of 12. The skill this lesson practises is building a prompt from task, context, and answer form. The worked example and questions in this lesson are the practice, not decoration: do them in writing before moving on.
### Worked text exampleWorked text example: Write the same prompt three times, changing only the task line, only the context line, and only the answer-form line, and note the effect of each single change.
Treat this example as practice in writing. It is not a model output, and it adds no new fact about the family. Keep the Yi Family angle in mind as you work: a bilingual open-weight family, so checking course claims against the family's own documentation is the habit to practise, and note in writing where the exercise relied on general description rather than a checked current fact.
Check your understanding
Before the next lesson, answer these questions in writing, without looking back at the lesson first. They test building a prompt from task, context, and answer form.
- Change only one line of a prompt at a time. What does each single change teach you?
- Write a prompt where the task is clear but the answer form is not, then fix the form.
- Why does a written prompt beat a prompt you only thought about?
If you are following a course, or choosing one, this guide is written for you. It explains the Yi Family in general terms, without asking you to trust a single source. The family itself is an open-weight family of language models discussed in courses about bilingual and open-model study, and about checking course claims against the model's own documentation.
Read with one question in mind: How should a beginner approach prompting for the Yi Family? The short answer sits in the opening paragraph above. The rest of the guide explains how to apply that answer, what to watch for, and how to practise it.
A prompt is easier to improve when it is written down before it is used. A prompt kept only in your head changes every time you repeat it, so you can never tell which change made the difference. Writing it down turns improvement into a comparison you can actually make.
## A way into this lessonWrite every prompt down before you use it, in three labelled lines. Change one line at a time and note what changes in the result. Prompts improved one line at a time teach you what each part does; prompts rewritten wholesale teach you nothing about which change mattered. Keep the Yi Family in mind here: it is a bilingual open-weight family, so checking course claims against the family's own documentation is the habit to practise.
Where learners go wrong
The first pitfall in prompting is changing everything at once. A prompt rewritten wholesale cannot teach you which part made the difference, so the next prompt starts from guesswork again. Change one labelled line, note the result, and then change the next. Keep the Yi Family in mind here: it is a bilingual open-weight family, so checking course claims against the family's own documentation is the habit to practise.
A third pitfall is to treat every lesson as equally deep. Some lessons need a quick read and one exercise. Others need slow work and a second attempt. Spending the same effort on both is how learners run out of time before the lessons that matter most.
## What to verify before you repeat a detail- Check the date of the source. Course material and articles about model families age quickly.
- Check whether the claim is about the family in general or about one specific version. Those are different claims.
- Check official documentation for the model family when a version, feature, or limit matters to your decision.
- Check your own result on a small, known example before applying an idea to important work.
- Take a prompt that failed and diagnose it: which part, task, context, or answer form, let it down?
- Write a prompt for a task you actually need, with all three parts labelled.
- Improve a working prompt by changing its answer form only, and record the difference.
- Write a prompt you would not use, and explain in two sentences why it fails.
Finish by writing the lesson's main idea as a question you can still answer tomorrow without looking back. The prompt you wrote down is the prompt you can improve; the one in your head is not. For the Yi Family, that line should mention building a prompt from task, context, and answer form, because that is what this lesson practised, and it should note one detail to check in current official documentation before repeating it. Write it now, before you open the next lesson, so the next lesson starts from your own words rather than from a blank page.
