Anthropic Releases Two AI Models

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 do Fable and Mythos share?
Correct answer: B — The same underlying AI model
Why: The company says they share the underlying model.
Clue in the story: Anthropic released Fable 5.2 and Mythos 5.2 on November 9. The company says they share the same underlying AI model.
Which version requires verified access?
Correct answer: B — Mythos
Why: The second paragraph identifies Mythos.
Clue in the story: Fable is widely available, while Mythos requires verified access for work in areas such as cybersecurity and biology.

The open question: accept different answers

Ask learners: Explain what the two versions share and how access differs.

One possible answer: They share the same underlying AI model, according to Anthropic. Fable is widely available, while Mythos requires verified access.

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 contrast with while

while Mythos requires

While contrasts broad availability with verified access, rather than describing two simultaneous actions.
