I just had such an amazing conversation with @demishassabis about how AI works under the hood, the future of the technology, and how we ensure people can feel comfortable using it. Can’t wait to share it with you!
Releasing a model this capable comes with risks. Without safeguards, Fable 5’s capabilities in areas like cybersecurity could be misused to cause serious damage.
Queries on a narrow range of topics will instead receive a response from our next-most-capable model, Opus 4.8.
Today, we're introducing Claude Fable 5 and Mythos 5, two configurations of our next major language model.
I'd normally highlight the numbers: It's SOTA on nearly all benchmarks. I want to talk about something else, because with Fable 5 out in the world, I think a third era quietly started today.
I lead Claude Code & Cowork on the desktop, so I think a lot about how people use AI to get work done. I believe we're about to see a major shift, moving from giving AI tasks to giving it responsibilities.
The AI bubble that we live in may not be excited by it. But all the normal people that don't follow AI on the daily are going to love it.
Personally, I'm excited for the improved Siri on my phone. I really like the "Describe a shortcut" feature.
"Describe an extension" is cool too. But I don't think it'll get me to switch to Safari. lol
I'm actually super impressed by what Apple showed off today. The biggest bummer is "coming later this year."
They seemed to have created the Siri everyone was hoping Siri always would be though.
The demos of Siri AI are very grounded in personal context. So you can talk to Siri and bring in real-world knowledge, but it also finally does the things you'd expect: Searches your messages, contacts, Maps history, etc. And it can take actions in these same places: Add photos to albums, send iMessages, add events to calendar, add reminders, etc. Good baseline stuff.
Fun times at @Microsoft Build this week. @mreflow and I were headed to an event this morning, but walked 20 minutes downhill in the wrong direction. Got rescued by @waymo but then met this hill. We survived though and got to check out some of the bonkers new computers from Microsoft.
I feel like moving to San Francisco could be a solid weight loss plan in itself.
Meet Gemma 4 12B!
A unified, encoder-free multimodal model designed to bring high-performance intelligence directly to your laptop, and released under an Apache 2.0 license.
Bridging the gap between edge efficiency and advanced reasoning. Here is what’s new with Gemma 4 12B: 👇
I didn't cover Claude Opus 4.8 on my pod because I don't think it's MEANINGFULLY better than GPT 5.5 as of May 29th.
We're entering the era where model releases start to feel like iPhone releases. Remember when every new iPhone was a genuine leap? Now it's a slightly better camera and you can't really tell the difference. That's where models are heading. 4.6 to 4.7 to 4.8. Each one is a little different. Nobody can agree if it's better or worse. The benchmarks say one thing, the vibes say another.
The thing that actually matters right now is what's happening around the models. Claude Code shipped dynamic workflows this same week and that genuinely changes what one person can build.
Codex shipped a desktop app with an in app browser that combines coding and knowledge work in one surface. Those are the releases that move the needle for people. The model underneath is becoming interchangeable.
I think we're maybe 6 months from nobody caring which model they're using the way nobody cares which engine is in their Uber. You just want to get where you're going.
When something genuinely changes the game for builders, I'll cover it on @startupideaspod. Opus 4.8 wasn't that. Dynamic workflows was.
I'd rather save you the hour.
Google Gemini Omni is widely underrated 🔥
Try Omni on Google flow today @googlegemini@google@googledeepmind
Gemini Omni lets you edit video and images through plain conversation, reshaping scenes, swapping objects, changing angles and actions while keeping characters and physics consistent across every turn. This is just the Flash model, so it’s only going to get better, and it’s already fast and seriously effective for creators, filmmakers, and marketers.

I don't know who needs to hear this but it is OK to think a new piece of tech is really cool AND also be worried about privacy, security, and the ethics surrounding the creation of that tech.
