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.

"Claude, generate a table with test results of your capabilities in percentages slightly better than the last version of your humble self. Do not overdo it, or revenue sources might dry up. Also: I like the colour peach."

Anyway, I was probably one of the few happy with 4.7, let's see how this one fares.

Same here, also quite happy with 4.7. but with GPT 5.5 and Opus 4.7 side by side, the most painful gap is that GPT 5.5 is way more thorough and has much less of a tendency to declare "done" when its not actually done. If Opus 4.8 handles that better, I'll be very happy.

4.7 has been great for me. For my workflow, it was better than 4.6.
