Claude Opus 4.6 User Guide: Model Selection, Projects, and Hands-on Artifacts

This tutorial focuses on clearly explaining the getting-started workflow for Claude Opus 4.6 on the web: how to choose the right model, how to use Projects to organize long-term tasks, and how Artifacts turn content into reusable “finished deliverables.” Follow the steps below and you can turn fragmented chats into a stable workflow.

Before starting a conversation: first confirm Claude Opus 4.6 is selected

After opening a new chat, first confirm in the model selector that the current model is Claude Opus 4.6, then start entering your request. If you find the response style or capability doesn’t match expectations, first check whether you accidentally selected another model—switching models directly affects the depth of output and the strength of reasoning.

When writing your request, try to clearly state the goal, constraints, and delivery format in one go, such as “output as a table/list/JSON.” Claude Opus 4.6 is very sensitive to structured instructions: the clearer the upfront constraints, the less rework later.

Use Projects to manage long-term tasks: lock in the context

Work that requires multiple rounds of iteration (such as papers, product documentation, or code refactoring) is best placed in a Project rather than scattered across multiple chats. After adding background information, a glossary, and style guidelines in a Project, Claude Opus 4.6 will follow these conventions more consistently, reducing inconsistencies over time.

The approach is to first create a new Project, then write the “goal description” and “rules that must be followed” as short bullet points. After that, each time you start a new chat within that Project, Claude Opus 4.6 can get up to speed faster.

How to use Artifacts: turn chat results into deliverable content

When you need a directly deliverable output (web copy, code files, proposals, scripts), having Claude Opus 4.6 produce it via Artifacts will be clearer. You can specify in your prompt, “Please provide the final version using Artifacts, and split it by chapters,” and the content will be presented more like a “document/file,” making it easier to copy, save, and revise.

When revising, don’t repeatedly rewrite the entire piece. Instead, point out the paragraphs to change, the parts to keep untouched, and the evaluation criteria. Claude Opus 4.6 is more reliable at localized replacements within Artifacts and is less likely to mess up content you previously confirmed.

The right way to feed files and images: reduce misreads and digressions

After uploading a file or screenshot, first ask Claude Opus 4.6 to restate “what it read,” and then have it summarize, extract, or rewrite—this step quickly reveals recognition errors. For tables or long text, specify whether you want it to “extract fields,” “compare differences,” or “generate conclusions,” so it doesn’t waste effort on irrelevant summarization.

If there’s a lot of material, it’s recommended to assign a code name to each file (e.g., Contract A, Quotation B), and require Claude Opus 4.6 to include the code name and paragraph location when citing. This makes it easier to trace sources later and is also better suited for team collaboration and review.
