Claude Opus 4.7 is the model to reach for when the work is substantial and worth getting right. Learn what it's best at, how it handles reasoning and effort, and when it's the right model for the job — with examples to follow along.
Models differ in how strictly they follow instructions or how ‘steerable’ they are. Opus 4.7 is likely to take your instructions more literally than Opus 4.6 did. This means you should think about what you need to emphasize or include within your prompt.
What this means for you: Write your directions once and clearly. And re-read any instructions Claude already has from you, including Project instructions or scheduled task prompts. Certain instructions like "be brief" or "skip the obvious parts" may now be followed more precisely.
Opus 4.7 reads images at higher resolution than prior models, which means small details come through more clearly: chart labels, values in a busy table, fine print in a screenshot. This applies anywhere you give Claude an image: a claude.ai chat, a Cowork task, Claude in Chrome reading the page in front of you.
What this means for you: Opus 4.7 is the model to pick when the details in an image matter. It can more reliably read from images like a full dashboard, a scanned form, or a chart with small labels, catching details previous models may have missed.
With Opus 4.6, extended thinking was a toggle you managed: turn it on for hard tasks, off for quick stuff. If you left it on, every question paid the thinking tax whether it needed to or not. Now, with Opus 4.7, extended thinking becomes adaptive thinking. This means that when the toggle is on, Claude makes the decision on how much to think per question. It answers simple things immediately and takes the time on hard ones.
What this means for you: You can leave Extended thinking on and stop managing it. Simple questions come back faster than they did on Opus 4.6 with thinking on; hard questions still get the depth. You get both without choosing.
Opus 4.7 is stronger at producing and reviewing its own work on office tasks, so the files it returns are more complete and correct on the first pass. Whether it's redlining a Word doc, building a slide deck, or working through a spreadsheet, it's more likely to spot its own layout and formula mistakes before outputting the file. That cuts down the rounds of back-and-forth it takes to reach something usable.
What this means for you: Choose Opus 4.7 when you're asking Claude to create office files. You'll get a draft you can open and continue working in rather than one you have to rebuild. This applies to file creation in claude.ai Chat and Cowork, and to Claude in Excel and Claude in PowerPoint.
Claude has tools it can use mid-task: web search for current information, files you've attached or put in a Project, and connectors like Google Drive and Slack. On any given question it decides whether to use them or to answer from what it already has.
Left to decide, Opus 4.7 reaches for those tools less often than 4.6 did. Unless you ask, it's more likely to answer from what it already has than to search or pull from a connector on its own.
What this means for you:Before you prompt, decide whether the answer needs a specific source. If it lives on the web or in your files and tools, name it in your prompt. If not, leave it out and Claude answers faster from what it already knows. Afterward, check in Claude's thinking what it drew from, and if it answered on its own where you needed something looked up or pulled from connected tool, follow up by pointing it to the right source.
Opus 4.7 makes good use of the context you've already given Claude — so it's worth setting up once.
