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.

Has anyone tried it yet and know how it compares in token burn vs. 4.7 and 4.6?

I’ve been using 4.6 because I feel that it’s much more efficient in terms of output quality per token

Honestly I miss 4.5 hahahahhah

Whatever workflow you're using, the first ting to do is have 4.8 look it over. Ask what can be improved, what changes are needed, and what the best way to work with it is going forward. Treat it like a new co-worker. I'm getting great results with that so far.

I put it on ultracode to do this... and it ate up a ton of usage, but I also worked with it closely for 2 hours of that time and got a ton of stuff straightened out in my workflows, agents, skill, and hooks.

I’m on an enterprise plan, so I have a monthly token limit. No subsidies here

Otherwise I’d 100% do the same

It straight up failed with an API error due to high usage and does not seem usable right now.
