Staying Current as the Yi Family Changes
Stay current as the Yi Family changes by checking official documentation and course updates, and by treating any model detail as a dated snapshot. This guide explains how to date your notes, so an old detail is never mistaken for a current fact. This lesson centres on dating your notes so an old detail is never mistaken for a current fact, 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: Model details change often. Treat anything in this guide about the Yi Family as a general description as of 31 October 2026. Before you rely on a specific version, feature, price, or limit, check the current official documentation for that model family. This guide gives no model specification, price, or benchmark score, because those details go out of date quickly and are easy to misstate.
## Lesson 11 of 12 in this text courseLesson 11 of 12 in the Yi Family Text Course. By the end of this lesson, you will be able to date your notes in writing, so an old detail about a changing family is never mistaken for a current fact.
### Worked text exampleWorked text example: Write a note as you would want to find it in six months: dated, sourced, with a status line, and no claim stronger than its source.
This example is a study exercise in text. It is not an output from any model, and it states 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
Answer these questions in writing, in your own words, before you move to the next lesson. They test dating your notes so an old detail is never mistaken for a current fact.
- Write a note you would trust in six months. What does it contain?
- Which of your old notes would you no longer trust, and why?
- How do you handle a detail you believe but cannot source?
Start with the family, not with a claim about it. The Yi Family 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. This guide sets that out in general terms for a learner who is following a course, or choosing one, and who wants a clear way to understand the material without needing to trust a single source.
The question at the centre of this guide is: How do you stay current as the Yi Family changes? The short answer is 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.
Old notes do not warn you that they are old. A note written without a date reads exactly like a note written yesterday, which is why an undated general description is the most quietly misleading thing in a study file. Dating takes seconds, and it is the cheapest accuracy habit in this course.
## How to approach this topicDate every note as you write it, not later. A note with a date, a source, and a status line can be trusted months later; a note without them cannot, however accurate it felt at the time. Make dating part of writing, not an afterthought. 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.
What to check before you trust 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.
The first pitfall in staying current is keeping undated notes. An old detail without a date reads exactly like a new one, so it gets repeated as current long after it stopped being true. Date, source, and status belong on the note itself, not in your memory. 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 practise only by reading. Reading about this family is not the same as working through a task with it. The checklist below is designed to close that gap.
## Practice checklist- Go through a page of old notes and add dates and sources where you can, marking the rest unchecked.
- Write a note about a changing detail in a form that will still be honest in six months.
- Find two notes of yours that contradict each other, and write how you would resolve the clash.
- Write a rule for yourself about when a note needs re-checking, and how often.
Before the next lesson, write one line about this lesson that only this course could have taught you. A dated note is a note you can trust later; an undated one is a guess dressed as a fact. For the Yi Family, that line should mention dating your notes so an old detail is never mistaken for a current fact, 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.
