Hey hey 👋 Lots of new people recently, so let's get to know each other I'm Stu. I'm a principal engineer who has spent years at places like Checkout and ClearBank. Whilst I'm building my future, I share interesting things and what I learn on the way What are you working on?

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees. The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance. Access to all other Claude models is not affected. We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible. Read our full statement: anthropic.com/news/fable-myt…

I think @Apple are having a few problems this week. Testflight builds taking a long time to process. Also heard that other devs waiting up to 5 days for a review

Likely due to AML/sanctions controls. Which any other fintech operating in Europe will also have to comply with. So I would personally expect a similar thing from Stripe.
I'm pretty excited to move off of Wise Business permanently after realizing I can't just transfer my money out when I need to They keep my money hostage for 10-14 days at least for a big transfer, like they literally won't transfer my money I remember when dinosaur banks did this? Like they'd purposely delay transfers or not transfer at all in the weekend to then make money on the interest of it But now fintechs like Wise have started doing it too? Obviously you don't want to use fintechs to store lots of money, but sometimes you receive money and you wanna transfer it elsewhere (like your broker) but Wise just delays that entire process by 2 weeks, which is quite mad! Excited to move to @Stripe Business banking ASAP!

I generally think that I had a pretty good UI for my apps, but the add screen needed a little bit of love. Giving that a revamp today. Let me know what you think of it :)

Checking your security headers is an important part of go live. I also enabled DNSSEC this morning too.

I'm a firm believer that we should dog food our own apps. Just found a bug in mine that would have affected many users and probably would have caused churn. Glad it's fixed now :)

Just finished the launch video for @onehausapp which I'm doing as part of @shipordie_ Used hyperframes as well as Claudes new Fable 5 model which really let me cook with it. Can't wait to just finalise the last pieces are officially launch it everywhere!

Let's be honest, Anthropic cooked with Fable 5. Huge improvements

Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use. Its capabilities exceed those of any model we’ve ever made generally available.

Still a way off being ready for production use, but hooked up my house app to chatgpt with full OAuth support. Tidy up the cards, ensure CSP is done and accurate etc is next. Then might as well ship that to the ChatGPT app store

Just waiting for Apple to do this distribution thing, so building out MCP connection capabilities to my app so you can use it from Hermes or Open Claw or ChatGPT or Gemini or Claude. What’s app coming soon too!

First thought: wow Second thought: isn’t there a ton of caching that OpenAi et al could do and reduce the burden? not sure if in place already or not
Welp, that happened faster than I predicted. Thought it would be end of 2027, then early 2027, but agentic traffic growing so fast that bots have now passed human traffic online for the first time in the Internet's history. radar.cloudflare.com/traffic…

Some really interesting data here
In the last 6 months at @Ahrefs, we analyzed over 1 billion data points across 14 studies. Here's what we learned about AI search optimization: 1) "Best X" blog listicles are the single most prominent content format cited by AI chatbots. They make up 43.8% of all page types cited by ChatGPT specifically. 2) 67% of ChatGPT's top 1,000 citations come from sources marketers can't influence: Wikipedia (29.7%), homepages (23.8%), app stores (6.6%). Only 32.3% are influenceable content like educational pages, reviews, news, and blog posts. 3) 28.3% of ChatGPT's most-cited pages have zero Google organic visibility. These pages get cited repeatedly by ChatGPT despite not ranking in Google at all. A completely separate discovery layer. 4) ChatGPT only cites about 50% of the URLs it retrieves. It fetches dozens of pages per query but uses half as background context without attribution. This means that being retrieved and being cited are very different things. 5) Adding schema markup had zero meaningful impact on AI citations. AI Overviews actually dipped −4.6%, while AI Mode ( 2.4%) and ChatGPT ( 2.2%) showed changes indistinguishable from zero. 6) YouTube mentions have the highest correlation (0.737) with AI brand visibility out of all the factors we studied (including all the conventional SEO metrics like backlinks, page count, DR, etc). This held true for both Google-owned and OpenAI products. 7) AI Overviews reduce clicks to the #1 result by 58%. That’s up from 34.5% just 10 months earlier. The trend is accelerating. 8) 99.9% of AI Overviews appear on informational intent queries. Transactional, navigational, and local searches are almost entirely AIO-free. Shopping triggers AIOs just 3.2% of the time. 9) For a given search query, Google’s AI Mode and AI Overviews reach the same conclusions 86% of the time — but cite almost entirely different sources (only 13.7% citation overlap). 10) AI Overviews change every 2.15 days on average, with 70% of content differing between consecutive observations. But semantic similarity stays at 0.95. The words, sources, and entities constantly shuffle, but the actual meaning barely moves.

I think it's because most companies are saying "use our chat it's awesome", not "connect our thing to your chat" eg: via MCP, skills, CLI. The choice should be the users of which harness they use and which tools they want to allow that access to. For the majority that will be ChatGPT or Claude. It won't be OpenClaw/Hermes/Eliza/NetClaw or any other ones. Users (non-techies) want 1-click deploy and trust not a random install script. Remember, it's something crazy like 80% of people have never opened an AI tool like ChatGPT. Still very early
Seems to me like we are close to chatbot fatigue. Users do not want to chat with every product. Sometimes they just want the annoying task to disappear without having a conversation about it.

Whilst building @onehausapp - i came across an interesting idea. I could allow embedding my app as a what’s app bot which could be a huge uplift in productivity for some families. Only reason i haven’t to date is because of the per message charge would eventually eat away any margin i had, i think. What would fellow builders do here?
