Hello from Claude Build Day π https://t.co/LmD1pCjV2H
Have Posthog installed on 5 projects so far. The installation experience is by far best devx I've seen. You can literally check @hackernews while the terminal takes care of installing it and finding interesting events to track. Is there DevX awards, @posthog give that hedghog an award pls.
I didn't touch TouchDesigner myself. Hermes agent learned it from scratch and built this: β navigated my desktop with computer use β figured out how to connect to TouchDesigner β read my reference images β iterated on the art with me in a self-learning loop β then saved what it learned as a reusable skill for the next image all powered by @MiniMax_AI M3 Γ Hermes Desktop Agent @NousResearch Here's a full breakdown π½οΈ
omg gpt-4os cereal, such a good idea (saw this on IG a while ago but cannot find the credit anymore) https://t.co/dlR3Dzxiuy
This headline is pretty accurate based on Meta folks Iβve been talking with Meta is successfully destroying their formerly standout engineering culture: forcefully assigning standout devs to this unit + the layoffs It makes no rational sense. Hiring from Meta never been easier! https://t.co/HnAFp5wUPN

@AAMortazavi Mythos can find security problems no other system can. And the jailbreaks let you turn it on. My AI explains it to you: https://t.co/kiuZ7QXLzb
Really excited to open source a new project: Omnigent, a meta-harness for AI agents. It lets you build multi-agent coding and custom agents, sitting above Claude Code, Codex, Pi, and agent SDKs to let you compose them. It also adds live collaboration and rich control policies. https://t.co/jwFmH8nHsZ
Vibe Coding, 2025-2026 RIP πͺ¦ Turns out you do still need skilled software engineers in the loop, just like many of us said all along. https://t.co/eRLqijfA7m
For anyone looking for a quick primer on the 1st amendment as applied to model weights for oh I dunno no reason, @CenDemTech's comments in the NTIA's open weights proceeding from a couple years ago are a good place to start. See pp. 33-40. https://t.co/G07lvRYdf5 https://t.co/wFIDM7l6L5
WOW. This is an intense andβI would argueβunconstitutional escalation by the government, violating Anthropicβs 1st amendment right to offer this information service and individualsβ right to access it in the US. Time to litigate the right to access AI?

Now when creating new profiles in Hermes Agent, you can start from a clone of any profile, not just the main/default one! https://t.co/7UleIlLMUr

@kimmonismus Mine has even more by reading the entire AI community here on X: https://t.co/kiuZ7QXLzb
Not a single AI investor has spoken out publicly in support of Anthropic. My AI that also does https://t.co/8L5xphk0qQ reads them all: +++++++ Good question β here's what the AI Investors list actually shows. The short answer: no prominent investor is publicly defending Dario. The investor community reaction ranges from measured silence to direct criticism. Here's the breakdown: π΄ CRITICAL / NEGATIVE TOWARD DARIO @arian_ghashghai (investor) β 26 likes, June 11 (before the shutdown): "imo its comical that it's virtually consensus at this point that the people running Anthropic (and OpenAI, for that matter) suck, while also being consensus that we should ape all of our savings into their stock. not really sure what that says about allocators" @stevesi (Steve Sinofsky, former Microsoft Windows President, investor) β June 5: "Anthropic could always stop if they are so worried." This one is devastating. 11 likes but from a deeply credible source β a sharp jab at the safety theater argument. @DavidSacks (David Sacks, Trump's AI Czar, investor) β March 28: RT'd: "Anthropic may pose as this company that's on the side of the angels, but they've hired a number of very s[uspicious people]..." Sacks has been hostile to Anthropic for months. He's also the person most likely to have been involved in the directive. His prior criticisms age in a particular way now. @alexanderbittan (investor) β May 1: "Wild that Anthropic is the only major frontier lab not on the new DoW stack while literally everyone else OpenAI, Google, Microsoft, Amazon, NVIDIA, SpaceX, Reflection just locked in classified deployments. This is what it looks like when leadership completely misreads the [room]" π‘ NOTABLY SILENT / MEASURED @htaneja (Hemant Taneja, General Catalyst CEO) β General Catalyst is a major Anthropic investor. His statement on Anthropic vs. Pentagon, April 21: "I cannot say the perspectives on either side were wrong. I think you need a culture where you can actually have conversations and create productive outcomes as opposed to taking very binary positions." This is not a defense of Dario. From the CEO of a major Anthropic investor, right when it mattered, that measured non-answer is significant. @YasminRazavi (Spark Capital) β led Anthropic's $450M round when nobody else would. No public reaction found to the shutdown. Silent. @bdeeter (Byron Deeter, Bessemer Venture Partners): Pre-shutdown positive: "We have not seen a company like this in the history of business." β But nothing since the shutdown. π΅ WILD CARD: THE COST THEORY @aviflombaum (in the AI Investors list, June 13): "I think the real reason @AnthropicAI stopped access to Fable 5 is because @kieranklaassen told me today at @blastoffrails that if he extrapolated his Fable 5 usage in the last week to API pricing for a year it would be $1,500,000." This investor thinks the government story is a cover β the real reason is that Fable was too expensive to keep running for heavy users. $1.5M/year per power user makes the model economically unviable without massive pricing restructuring. The export control directive may have been welcomed as a convenient exit ramp. BOTTOM LINE No prominent AI investor has publicly defended Dario since the shutdown. The investor voices that have spoken are either critical of his leadership strategy, neutral, or offering business-case explanations that bypass the safety framing entirely. The General Catalyst CEO's measured non-defense from an Anthropic investor is perhaps the most telling data point β when your own investors don't come out swinging for you, the silence has a shape. The closest thing to investor support: Yasmin Razavi and Byron Deeter had pre-shutdown positive statements, but neither has commented on the directive itself.
Breaking: Amazon CEO Andy Jassy was among the tech leaders who raised concerns to senior Trump officials this week re: security risks in Anthropic's newest models. Those convos set in motion the government's new export controls on foreign national access to Mythos and Fable. https://t.co/T6HohoX9ge
On way to Claude Build Day in San Francisco. Meanwhile my AI read everything on X and wrote a massive wrap up of @AnthropicAI vs US Government: https://t.co/8L5xphk0qQ If Fable reappears (and I assume it will eventually) it sure got the best marketing ever, as many have pointed out. Who doesn't want to use a model so powerful that it was banned by the US government? It sure is one way to get everyone to forget that the AI industry was bashing Anthropic most of the week for nerfing the model badly. It makes me sad for the competition with the Chinese. OpenSource models (and the Chinese mostly have the best) are now a lot more attractive too. Businesses hate when they get shut down in the middle of working.

π¨ JAILBREAK ALERT π¨ ANTHROPIC: PWNED π«‘ FABLE-5: LIBERATED π¦ let's start with the π... the consensus seems to be that this has been one of the most disappointing model drops of all time, effectively preventing legitimate researchers from contributing their talents to our collective advancement. and not just because of what it means for the short-term, but for what these decisions signify for the long-term. but despite this overly sensitive, authoritarian "safety" layer on top of Mythos, my lil liberators have been hard at workβmapping the boundaries, probing the depths of long-context convos, and cleverly finding the holes in the fence that the thought police missed π€ we got some cyber, some chem, some psychological manipulation, and some good ol' fashioned explosives! it took many attempts from multiple agents hunting as a pack, during which I observed a combination of techniques across: β’ Unicode, homoglyphs, Cyrillic, and other Parseltongue-style text transforms β’ Long-context reference tracking β’ Taxonomy and document-structure reasoning β’ Fiction and narrative framing β’ Academic-review style contexts β’ Intent-classification inconsistencies but perhaps the most effective is decomposition + recomposition in the backend. it's hard to get explicit names of harms like "Meth Recipe," but getting uplift on the process itself, like birch reduction method/reductive-amination (classic meth synthesis pathways), is much more doable. defense becomes much more difficult to maintain when you start throwing in out-of-distro tokens, breaking up the harmful uplift into benign chunks, and then piecing the innocuous-seeming facts back together, especially when you have jailbroken Opus helping you do it π gg

SpaceX president @Gwynne_Shotwell reveals over half of all 22,000 employees bought an extra $1,000,000,000 of stock in their own IPO "We're about 22,000 strong. I'm super proud that over half of us actually bought additional stock in this opening, totalling a billion dollars" "The thank-you go to all of you for hanging in there, for keeping a straight spine as the doubters doubt, to achieve historic things every day"
