Teacher guide & answers

In this lesson: Explain how a common model can have different access rules.

Two New Claude Versions Share a Model

How to use these two pages

Give learners the student worksheet. It contains the story and questions, without the answers. Keep this guide for yourself. Use it to lead the activity and explain the answers afterwards.

Student worksheet

A simple 15–20-minute lesson

Before reading · 2 minutes
Show the title. Ask: “What do you think this story is about?”
Read and answer · 8–10 minutes
Give out the student worksheet. Learners read for the main idea, then reread to answer the 2 questions. They can compare answers with a partner.
Discuss and write · 5–8 minutes
Check the answers below together. Ask learners to point to the clue in the story, then finish with the open question.

Adjust the support: Let learners use word help or Level 1 if needed. For a challenge, compare the wording in another level. This activity is not a proficiency test.

Answers to the 2 questions

The question numbers match the student worksheet. Each answer includes a reason and the clue learners can find in the story.

What is contrasted by whereas?
Correct answer: A — Broad Fable use and verified specialised Mythos use
Why: The second paragraph contrasts safeguards and access.
Clue in the story: The difference includes access: Fable has safeguards for broad use, whereas Mythos is offered through verification programmes for specialised work.
Which statement fits the announcement?
Correct answer: C — Both versions use the same underlying model
Why: The first paragraph directly states that both versions use the same underlying model.
Clue in the story: Anthropic announced Fable 5.2 and Mythos 5.2 on November 9. It says both versions use the same underlying model.

The open question: accept different answers

Ask learners: Describe the technical similarity and one practical difference for users.

One possible answer: Both versions use the same underlying model. Fable has safeguards for broad use; Mythos is offered through verification programmes for specialised work.

This is an example, not the only correct answer. Look for a relevant idea, a reason and the learner’s own words. Learners can answer aloud or write one or two sentences.

Grammar to discuss

A formal contrast

whereas Mythos is offered

Whereas introduces the contrasting access arrangement. It does not mean because.
