Teacher guide & answers

In this lesson: Distinguish a model’s lineage from what company evaluations establish.

New Cybersecurity Model Pairs Stronger Tests With Access Controls

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.

Which conclusion follows from the second paragraph?
Correct answer: B — The reported improvements do not establish perfect future behaviour.
Why: The paragraph explicitly distinguishes evaluation results from a guarantee that the model will always stay within scope.
Clue in the story: The company reports improvements in both technical performance and respect for task boundaries. These are results from its evaluations, rather than a guarantee that the model will always remain within scope.
How does the system card describe the model’s relationship to GPT-6 Astra?
Correct answer: A — It is a specialised version of GPT-6 Astra.
Why: The opening paragraph identifies GPT-6 Cyber as a specialised variant of GPT-6 Astra for authorised cybersecurity work.
Clue in the story: OpenAI introduced GPT-6 Cyber on November 5, describing improved vulnerability discovery and testing. Its system card identifies the model as a specialised version of GPT-6 Astra for authorised cybersecurity work.

The open question: accept different answers

Ask learners: Explain how GPT-6 Cyber is related to GPT-6 Astra and what readers should avoid concluding from the reported evaluation improvements.

One possible answer: GPT-6 Cyber is a specialised version of GPT-6 Astra for authorised cybersecurity work. The company reports better performance and respect for task boundaries, but these results do not guarantee that it will always remain within scope.

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

Rather than limits how evidence should be read

rather than a guarantee that the model will always remain within scope

The contrast tells the reader to interpret the claims as evaluation results. Always would extend the claim to every case, which the sentence rejects.
