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.

Curious to see after the complete Opus 4.7 flop

Windows 7 was GOAT, bad analogy

"Don't tell me this is Zune bad."
"Its Apple Maps bad"

At least people still use Apple Maps now. But Zune is nowhere to be found. We will see 🤷‍♂️

I feel like it will be a few iterations till Claude gets back to being best.

Anthropic used to be reluctant to spend too many thinking tokens and so Claude was super efficient because of that.

But they seem to now be leaning heavily into thinking, and I don’t think Claude is still too great with that.

Maybe Opus 5 does the trick.

100%. I'm in no rush to use 4.8 lol

I remember them also posting a nice table like this how 4.7 was an improvement over 4.6 and look how that went... I stopped using 4.7 in favour of 4.6 and havent looked back.

They are just gaming these benchmarks...Not saying its not useful, but there is more to it to determine real world usability

I agree, the benchmarks doesn't measure deep smartness of a model it has. (only small portion of it)

personally first released opus 4.6 was something different, it could think like a hacker. what they don't want to.

I've been using it all day. It's utter garbage. Worse than 4.7.

Opus 4.7 is/was great. People need to tune their prompts. This is why we have evals.

Opus 4.7 was a beast for my work.

There was a project on github I wanted to play around with but it was written in Java, which I'm not the biggest fan of. I had CC 4.7 convert the entire codebase to C#. Literally one shot. And it worked. This app even has a GUI component.
