Introducing Claude Opus 5.5, the first model in our new Claude 5.5 family. It performs at the level of Claude Fable 5.1 for most tasks, and costs 40% less to run than Opus 5.

We’re introducing Claude Fable 5.1 and Claude Mythos 5.1. They're the world’s most advanced models for coding and knowledge work.

Correction: the QT video was not half-bounce. I was too excited and launched the debug build. This one is faster. It misses the peak just a little, but that was because of the screen recording software.

I love how many people are attaching to the "half-bounch" startup time metric. I used to do paid macOS dev ~20 years ago and most macOS devs I knew then used the bounce metric! Back then multiple bounces was the norm due to HDDs. One bounce really wasn't possible until SSDs. We've lost this obsession and its time to bring it back.

OpenRouter is joining Stripe. We started OpenRouter with a simple mission: intelligence should be multi-model. Today, we are the largest AI marketplace & gateway, processing 10T+ tokens daily on 400+ models. Joining @Stripe gives us the opportunity to accelerate that mission.

Opus 5 is available on BoltAI. Refresh the model list to see it ✌️

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