Claude Opus 4.7 Is Here

Anthropic just announced Claude Opus 4.7 yesterday, and here is my take on the new model after reading the blog post and doing a bit of research on their rollout plans from previous models.

What’s New

The headline is a 13% improvement on a 93-task coding benchmark over Opus 4.6. Rakuten’s SWE-Bench saw 3x more production tasks resolved, which is the kind of real-world metric that actually matters. Benchmarks are one thing, but “can it handle my actual codebase” is another.

The big quality-of-life improvement is that Opus 4.7 is better at verifying its own output before telling you it’s done. If you’ve ever had a model confidently hand you broken code and say “there you go,” you know why this matters. It handles long-running tasks with more precision, and the instruction following is noticeably tighter.

There’s also a major vision upgrade. The new model accepts images up to 2,576 pixels on the long edge, which is more than 3x the resolution of previous Claude models. If you’re working with technical diagrams, architecture charts, or screenshots of code, that’s a real improvement.

When Can You Actually Use It?

For enterprise customers, Anthropic says Opus 4.7 is available from your cloud vendor: the API, Amazon Bedrock, Google Cloud Vertex AI, and Microsoft Foundry. But most of us aren’t using the API directly.

As of right now, Opus 4.7 is not yet available in Claude Code or the desktop app. It’s also not showing up in the model picker on claude.ai for Pro plan users. Anthropic’s announcement says “available today across all Claude products,” but that doesn’t seem to have fully rolled out yet for consumer plans.

Looking at previous releases, Opus 4.6 launched on February 5th and was accessible on claude.ai and the API the same day. Historically, Anthropic hasn’t gated new Opus models behind higher tiers, so there’s no reason to think Pro, Max, Team, and Enterprise won’t all get access. The question is just when. If past patterns hold, it should show up within a few days. Keep checking your model picker.

Claude Code Users

As of today, Claude Code on the stable release is still on Opus 4.6. I’m not sure if it’s available on the bleeding edge builds, but for most people it’s not there yet.

The announcement mentions a few Claude Code features coming with 4.7:

  • /ultrareview is a new slash command for dedicated code review sessions. Pro and Max users get three free ultrareviews to try it out.
  • Auto mode has been extended to Max plan users, letting Claude make more decisions autonomously.
  • The default effort level is being bumped to xhigh (a new level between high and max), which means the model will spend more time reasoning through harder problems.

Once Opus 4.7 does show up in Claude Code, remember to check any custom agents or skills that have a model hardcoded in the frontmatter. If you’ve got claude-opus-4-6 specified in your .claude/commands/ directory or agent configurations, those will keep using the old model until you update them.

Anthropic also notes that Opus 4.7 follows instructions more literally than previous models. Prompts written for earlier models can sometimes produce unexpected results. So if something feels off after switching, it’s worth re-tuning your prompts.

The Tokenizer and Cost Changes

One thing to be aware of: the tokenizer has been updated. The same input text will produce 1.0 to 1.35x more tokens than before. That means your costs could go up slightly even at the same per-token pricing ($5/million input, $25/million output, unchanged from 4.6). Not a dealbreaker, but worth watching if you’re running high-volume workloads.

Pricing hasn’t changed, the coding improvements look useful, and important to know that the model ID is claude-opus-4-7. Keep an eye on your model picker over the next few days.
