My review of Claude Opus 5.5: It passes the five hour limit test. I can use it for five hours without running out of usage. That’s it. That’s the review.
FIRST RELEASE OF THE DAY: CLAUDE OPUS 5.5!!! Supposed improvements on communication, it costs 20% less than Opus 5 at $4 per input, $20 for out, and $0.20 for cache read. It also uses fewer tokens and costs 40% less than Opus 5 on 'typical workloads'. It seems to beat F5.1 on most benchmarks
Introducing Claude Opus 5.5
Claude Opus 5.5 leads in agentic coding and knowledge work, and costs 40% less to run than Opus 5 on typical workloads.

I had access to the new Claude Projects & was able to do some very complex work Here, I asked it to go through all the images, videos and records about Umberto Eco's famous 33,000 book library & try to reconstruct it, including book locations, in 3D. Not perfect, but wow eco-library-map.netlify.app
if you find yourself agreeing with this guy it’s worth giving it a second or third or fourth thought xcancel.com/davidsacks
It’s weird how everyone is having big apprehensive reaction about a technology that changes the nature of humanity
NY Fed: Recent data suggests "firms are continuing to adapt and change due to AI use, but not by eliminating vast numbers of jobs. Instead, this new technology is reshaping work itself, with firms investing in their existing workforces rather than replacing large swaths of people."

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.

Holy fuck. Is it really happening. This can't be fucking real.
Very sad to hear about Dolly Parton passing, but her memory will be powerful for a long time. I think we all have a moment where we thought, wow, yeah, I want to behave more like her
We are happy to report that the tracks north of Portland are opening! Tomorrow, on August 19, all Amtrak Cascades trains resume normal service, except Train 500 which will resume on Thursday, August 20. Let your summer travel plans resume. We’ll drive! 💚🤎🤍
Portlanders and PNW people! There's a street fair today at Clinton Street and 25th, raising money for the bail fund! There will be vendors, music and a raffle from 1-5 PM PST!
🎶 It’s been a long day, without you, my friend. And I’ll tell you all about it when I see you again. 🎶
I say this with love in my heart but the argument about does rooting for the usmnt mean you support the US/FIFA has been done essentially for DECADES. ask any football fan how they feel about the NFL or team ownership! This dissonance is well-documented, explored, and written on!
PHOEBE BRIDGERS: and what *I'M* saying is that pre-snap motion has become such a staple of Shanahan Tree coaching schemes that modern defenses have fully adapted by filling any potential leverage gaps ANDY REID: (nodding while eating a big bowl of spaghetti)
The most interesting Fable tip I've heard so far is to let the model use its own judgement as much as possible I told it "For all coding tasks use your judgement to decide an appropriate lower power model and run that in a subagent" and it seems to be saving tokens simonwillison.net/2026/Jul/3/j...
Fable's judgement
One of the most interesting tips I got from the Fireside Chat I hosted with Cat Wu and Thariq Shihipar from the Claude Code team at AIE on Wednesday was …
