None of this was some weeks long back and forth. I was at Anthropic's HQ on Friday reporting when this all unfolded. Dario is not at a wellness retreat. The Feds seemed to be scrambling to try and make an example of Anthropic again. This is not technical. It's petty.

Rio may have found the most overqualified municipal employee in human history.
SITUATION DETECTED: The city of Rio de Janerio has post-trained a model. Based on Qwen 7/2, Rio 3.5 Open 397B adds SwiReasoning on top of the base Qwen model — a framework that dynamically switches between standard chain-of-thought and latent-space reasoning, guided by entropy-based confidence signals, so the model only "thinks out loud" when it needs to and otherwise reasons silently in hidden space for better token efficiency.

Sir, they’re not pausing AI research. Rio de Janeiro's mayor just dropped a SOTA open source model and it’s outperforming Qwen 3.7.
Alibaba Qwen3.7 slowly fading into irrelevance at the frontier due to proprietary stance. In it's place we have Minimax M3 and... *checks notes* Rio 3.5 397b, made by the municipal IT company of Rio de Janeiro's city government. huggingface.co/prefeitura-ri…

this timeline is so weird
Wait what? Rio 3.5 Open 397B, developed by IT company of Rio de Janeiro's city government is now SOTA open source and even outperforming Qwen 3.7? What is happening today. Never heard of them before.

If she wasn’t working for Elon Gwynne Shotwell would be hailed as an incredible success story and the most powerful woman in aerospace. Instead it’s radio silence from the media

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…

According to Grok, Andrej Karpathy is an EB-1 extraordinary ability green card recipient, not a US citizen. Thus under these new restrictions he is not permitted to use, or work on, Mythos 5 or Fable 5 as of 5:21pm tonight.

wtf
As a result of a US government directive, we are suspending access to Claude Fable 5 for all users. You can continue to use all other Claude models. Here’s what this means for you: Across Claude products, new sessions will run on your selected default model or Opus 4.8, and existing Fable 5 sessions will end with an error. On the Claude Platform, requests to Fable 5 will also return an error. Please update your integrations to other Claude models. We know this is a disruption to your workflows; we appreciate your patience and support.

Suporte da Cloudflare confirma que bloqueios a endereços de IP deles estão se dando unilateralmente pela Claro, Vivo e Nio conforme anunciei mais cedo. E como tenho dito, esses bloqueios se dão por ordens sigilosas de autoridades brasileiras. Mais detalhes nesse thread.

Confirmo que há todos os indícios típicos de bloqueio nacional determinado pela Anatel no dia de hoje para api.github.com. Nas quartas-feiras, geralmente em dias de jogos de futebol, a agência de reúne com as maiores operadoras do país e determina o bloqueio de endereços utilizados pelos TV boxes. A lista de endereços bloqueados é mantido em sigilo pela agência, algo que tenho criticado em artigos, entrevistas e palestras. Os indícios são: 1) O fato de ocorrer numa quarta-feira e pelo relato desse internauta que me acionou, ontem o problema não ocorria. 2) O fato do IP 4.228.31.149 para qual aponta o FQDN api.github.com estar bloqueado somente na Claro, Vivo, Nio, Algar e TIM e *NÃO* em ISPs regionais conforme posso testar com o comando globalping. 3) O fato de outros endereços IP contidos no mesmo bloco /24 serem normalmente alcançáveis, o que exclui problemas de roteamento já que todos os IPs entre 4.228.31.1 e 4.228.31.255 necessariamente pertencem a mesma rota (vide exemplo 4.228.31.3). Recomendo que os afetados entrem em contato com seus provedores mostrando evidências coletadas a partir de sua casa ou empresa e exijam uma resposta do porquê não havia rota para 4.228.31.149 na noite de 10/06/26 enquanto para 4.228.31.3 há. Nesse thread a seguir, colocarei algumas informações úteis sobre o problema.

It's official, we have AGI.
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.

if you’re still writing loops that prompt coding agents you’re falling behind. you need to build a meta agent that infers what loops you would have wanted based on your vibe and then write those loops

I admire Fabrice Bellard. He is almost certainly a better overall programmer than I am.
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.
