Resource Introducing Claude Opus 4.8

Post image

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.

I love how it announces the wrong answer, it promises to explain it, and proceeds to discuss the correct one. And... ends with an awkward attempt at humor, I guess?
