Questions about working with Opus

How can I analyze a long document effectively

State the question before asking for a summary. Identify the sections that matter and request references to the relevant passages. For a substantial document, start with an outline of the argument and then examine the sections that need a closer reading.

How should I compare several reports

Label each report and ask for a comparison using the same criteria. Keep differences in dates, definitions and assumptions visible. Request a separate section for claims that disagree, then verify those claims in the original material.

How do I keep my voice when revising

Give an example of the tone you want and name the passages that should stay. Describe the effect you want on the reader, such as a quieter ending or a more direct explanation. Ask for a focused revision and compare it with the original before accepting it.

What should I provide for a useful code review

Include the relevant code, expected behavior and the change you are considering. Describe known constraints and ask about edge cases, dependencies and tests. Review the proposal and run the appropriate checks before applying it.

Can I include visual reference material

Yes. Opus 4.6 can understand images alongside text. Add a clear screenshot, diagram or photograph and ask about the details relevant to your task. Provide a closer view or the original text when fine labels or small figures matter.

How can I review the choices in a revised passage

Compare the revision with the surrounding draft and the effect you intended. Look at which details it keeps, what it leaves unsaid and how the ending changes the passage. Our Writing Sense report explains a way to examine these choices in context rather than treating a polished sentence as enough on its own.

Can the model create images or video directly

The model itself produces text. It can analyze image input and help write a script, plan, prompt or code for a visual project. Producing an image or video requires the appropriate separate tool and its available settings.
