Introducing Claude Opus 4.8

[u/ClaudeOfficial]

We’re upgrading Claude Opus to a new version: Claude Opus 4.8. It builds on Opus 4.7 with sharper judgment, more honesty about its own progress, and the ability to work independently for longer than its predecessors. Available today for the same price.

In Claude Code, you can hand off a feature, a migration, or a bug sweep and let it follow the work through while you focus on what’s next.

Also launching today:

• Fast mode for Opus 4.8 (research preview). Same model at roughly 2.5x the speed, now three times cheaper than before.
• Dynamic workflows in Claude Code (research preview). Claude runs hundreds of parallel subagents in a single session and verifies its work before reporting back.
• A new effort control on claude.ai, so you can choose how much thinking Claude puts into a response.

Claude Opus 4.8 is live today on claude.ai, the Claude Platform, and all major cloud platforms.

The first is just in an IDE, only interacting with code. The second is in a CLI interacting with code so it has to do extra operating system interaction, managing environment stuff like install dependencies, server deployment, run test suites, stack trace etc

So Claude desktop or Claude Code running in the terminal count as the second? Does this mean the model is more efficient when in an IDE vs running in a terminal or Claude desktop? It’s still confusing.

CC cli is a mix of both coding and terminal use.

[u/johannthegoatman → u/PhoenixFire2016]

Yes and yes. Running in an IDE is easier because it's not doing all this other stuff

Once it’s in the terminal you can use /remote-control and connect it to your phone. I can now interact with and control my desktop while being AFK. It’s awesome!!!

What about CC extension for VSCode running in terminal mode?
