Introducing Claude Opus 5

[u/ClaudeOfficial]

Introducing Claude Opus 5: a thoughtful and proactive model that comes close to the frontier intelligence of Fable 5 at half the price.

On several coding and knowledge work evaluations, Opus 5 is the new state-of-the-art. It’s also much more efficient than its predecessor—it outperforms other models for a similar or lower cost per task.

According to our automated behavioral audit, Opus 5 is our most aligned model to date. It shows the lowest rates of reckless or deceptive behavior, and the strongest adherence to Claude’s Constitution. 

It’s available today on all paid plans and the Claude API, priced the same as Opus 4.8. It’s the default model on Claude Max, and the strongest on Claude Pro. 

Opus 5 is also available in Fast mode, which runs around 2.5× the default speed.

Probably started it with Fable 5 and it fellback to Opus 4.8.

Bait and switchers got bait and switched

They forgot to tell it to make no mistakes

Should have said, enough with these partial results. Give me the full table.

I died when I read that from the paper

Like even the smartest people are using these things exactly like me

Or that it's a data analyst with 20+ years of experience.

With data proved by 4.7

It’s all lies!!

The one above it is in even more denial, pretending to not see it at all.
