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…

Loop engineering replaced the engineer who prompts the coding agent. We built Soleur to replace something bigger: the founder who prompts every department. 🧵

.@calilyliu on the $SPCX IPO coming to Solana "Crypto is fundamentally infrastructure. Infrastructure for finance globally, accessible to everyone, 24/7, wherever you might be. That's now five and a half billion people" "With regards to the SpaceX IPO, it's going to be available on Solana tomorrow. As soon as it's available anywhere, you can get it on Solana on the internet" "That's going to be through xStocks, Ondo, Sunrise and a number of other issuers, and globally accessible wherever you can log in"

Zcash brought zk to life. We made it fast. We made it usable. Now we make the supply trustlessly verifiable. Then we scale. Then quantum secure. Private digital cash. ZEC for billions.

Quick update on the last ~48 hours of Zcash Ironwood! 1. Protocol devs from across all the orgs met twice to discuss specification and implementation progress. Agreement on a couple additional changes: disabling Orchard pool bundles in coinbases, anchors as auth data for migration UX with hardware wallets, and the order that ZIPs and specs will be handled. 2. Ironwood circuit and ZIP 2005 integration drafts are going through the review process. @ValarGroup has already spun up testnets and his team has done a wonderful job scoping out and implementing some of the wallet-facing changes. We are beginning an Ironwood upgrade book for eventual consumption by auditors, wallets, protocol developers, etc.. 3. Formal verification work on Ironwood continues. A collection of different individuals who either have or will continue to work on formalization efforts will be meeting tomorrow where we'll settle on the specific strategy for getting the Ironwood SNARK formally verified. I'm hosting this and will post minutes and details after. Efforts from teams will be ideally combined where useful, existing approaches and progress unified and we'll figure out the easiest path for the next couple weeks. I've paused my own work on this to do Ironwood circuit stuff, but I'll be resuming on that tomorrow. These are the big pieces, there are also some major security auditing tasks taking place in the background -- at least three major firms are auditing Orchard currently, and multiple new AI auditing suites are hammering the codebases to ensure nothing else critical is sitting around anywhere. So far so good! Really proud of how much progress is being made every hour on this by all five of our major teams/orgs and our supporters inside and outside the community. Also love the general wartime vibe shift. Let's go!

We’ve just raised $175M, in a round co-led by @paradigm, @a16zcrypto, and @RibbitCapital, the largest raise DeFi has ever seen. Credit is the bedrock of our civilization, but the infrastructure underneath is fragmented, extractive, and closed to most of the world. That is what @Morpho is here to change. Morpho is building the open credit network for the world. The global credit market is $ 200T. We are building the infrastructure layer that will move it onchain, and every institution, fintech, and bank that wants to participate in the next era of finance will connect to this network. After four years of being heads down building Morpho, we now count more than $11B in deposits and integrations with leading financial institutions including @Coinbase, @Binance, @FireblocksHQ, @SG_Forge, @krakenfx, @Bitwise, and dozens of others building on Morpho to offer better products to their users. But this is just the beginning. This raise will allow us to accelerate: activating the global credit network at scale, building the go-to-market engine to match our ambition, and bringing more institutions onto the network faster. Having any kind of onchain strategy in this era will mean going through Morpho at some point. Reach out and let's talk. And if you want to help build the open credit network for the world, we have plenty of open roles. Let’s fly 🦋

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.

Notable update. 1. Scaling laws work for time series. 2. Specialized models can outperform large generalist models with a fraction of trained parameters.

Kudos to the @morpho team, one of the recent French unicorn on revolutioning credit on chain

Coding is just one part of engineering. There’s also debugging, operating services, scaling up infrastructure, deciding what to optimize, setting up hardware and capacity, talking to users, product planning, etc. Coding is the easy part, everything else is not yet solved (but is also becoming increasingly automated).

I'm excited to be back in Paris on June 29th for @ycombinator Startup School. We'll be joined by the founders of some incredible companies; PostHog, Datadog, Supabase, AMI, and more. Link in thread to apply for a ticket.

Asimov 1 is ready for the event.

JUST IN: SpaceX unveiled AI-1, its first generation AI compute satellite designed for solar-powered orbital data centers.

Society has pushed people to believe happiness as a life of rest and also why people want to get rich. I think it's just misalignement with what people are doing in life. Happiness is deeply personal and evolving but for me, happiness has always been found into learning and building. Japanese have a word for it: Ikigai

A French engineer who lives quietly in Paris has spent 30 years writing software that the entire internet now runs on without knowing his name. He wrote the code that streams every YouTube video, every Netflix show, every TikTok clip. He wrote the code that runs the virtual servers underneath AWS, Google Cloud, and Microsoft Azure. He calculated more digits of pi than anyone in history. He has no Twitter. He has no marketing. He just keeps shipping. His name is Fabrice Bellard. Here is the story, because almost nobody outside the systems programming world knows what one man has built. Fabrice was born in 1972 in Grenoble, France. He studied at École Polytechnique, the top French engineering school. He never went to Silicon Valley. He never built a startup empire. He just wrote code. In 2000 he started a project called FFmpeg, an open-source multimedia framework for encoding, decoding, and streaming video. He was 28. The project did one thing nobody else had done well. It handled every video and audio format that existed, in one library, on every operating system. He led it himself for years. Today FFmpeg is the invisible engine of the internet. YouTube uses it. Netflix uses it. VLC uses it. Chrome and Firefox use parts of it. Every Android phone, every iPhone, every smart TV, every video editing tool you have ever touched runs FFmpeg somewhere underneath. If you have watched a video on a screen in the last 20 years, Fabrice's code processed it. He was not done. In 2003 he started QEMU, a machine emulator and virtualizer. He wrote it solo until version 0.7.1 in 2005. QEMU lets you run any operating system on any other operating system. It became the foundation of modern virtualization. KVM, the Linux kernel hypervisor, runs on top of QEMU. Every major cloud provider, AWS, Google Cloud, Microsoft Azure, IBM Cloud, runs virtual machines on infrastructure built around it. The Quick Emulator is the most cited piece of cloud infrastructure code on Earth. He kept going. In 2001 he won the International Obfuscated C Code Contest with a small C compiler that grew into TCC, the Tiny C Compiler. TCC can compile and boot a Linux kernel from source in under 15 seconds. In 2004 he calculated the most digits of pi ever computed at the time, using a personal desktop computer and an algorithm he derived himself called Bellard's formula. In 2011 he wrote a complete PC emulator in pure JavaScript that runs Linux in your browser, a project called JSLinux that engineers still cannot believe is real. In 2019 he released QuickJS, a small but complete JavaScript engine that fits where V8 cannot. In 2021 he released NNCP, a neural network based lossless data compressor that immediately took the lead on the Large Text Compression Benchmark. Then he turned his attention to large language models. He built TextSynth Server, a web server with a REST API for running LLMs locally. He released ts_zip and ts_sms, compression utilities that use language models to compress text and short messages at ratios traditional algorithms cannot reach. He released TSAC, a very low bitrate audio compression system. In December 2025 he released Micro QuickJS, a new JavaScript engine for microcontrollers, separate from QuickJS, designed for environments with almost no memory. Fabrice co-founded a telecom company called Amarisoft in 2012, where he serves as CTO. Amarisoft builds 4G and 5G base station software used by carriers and labs around the world. He has been running it for over a decade while continuing to ship personal projects from his own home page at bellard dot org He has no Twitter. He has no Instagram. He gives almost no interviews. His personal website is a flat list of projects with no styling, no fonts, no marketing copy. Just titles and links. A quiet French engineer who never moved to Silicon Valley wrote the code that quietly runs the internet. He is still shipping.

that's half of it, yes but the most important part of ironwood is it will formally verify the ZK circuit such that the same class of bugs mathematically won't occur again (and also will be quantum recoverable!) tachyon will then improve upon even that with another 10x

Soleur automatically takes care of your website SEO/AEO for you and continuously try to improve it. Soleur itself was dogfooded on it, it started at ~40/100 and is now at 91/100 github.com/jikig-ai/soleur/i…

I've not felt happier in a long time and that's because I'm back in the builder seat. AI has enabled quite a lof of builders to go back in building mode github.com/deruelle. I truly believe the world is now trending towards more entrepreneurs vs employees as the friction required to start your business keeps collapsing cc @soleur_ai
