This is weird as hell — something I expect and believe is the unhinged unpredictability of bureaucrats in this admin… but there’s still a lot of open questions on Anthropic’s side. x.com/sophiacai99/status/206…

This whole thing stinks like bullshit… So you’re the biggest, most promising emerging tech company in the world. The government calls you and says you need to turn off your flagship product. And you just… do it? Your lawyers don’t pushback? No hearing? Unprecedented government overreach and your first instinct is to synchronize tweets with the DoD and have a blog post explainer ready? A week after you filed for IPO? You turn off your brand new, hottest, most hyped new product at the behest of the (historically predictable) Trump administration? This shit doesn’t add up to me. Anthropic is a very bad company doing some very bad and sketchy things, and I hope the brilliant minds behind Claude will leave and go rebuild it elsewhere.

I’m so happy Fabio beat me to this and released all the code open source. This is the move - low cost inference on a custom ASIC (or even FPGA). It wouldn’t be a stretch to imagine a cracked team selling literal “model cards”. I love this! Thanks @FGuzmanAI
56,000 tokens/sec at just 80 MHz. 🤯 I burned a full Transformer with KV cache into a custom chip. Designed gate by gate as a 100% digital integrated circuit. Prototyped on a FPGA. (No GPU. No CPU) Just pure digital silicon running @karpathy microGPT, spelling out names on a tiny LCD. This is GateGPT 👇

if the admin wants people to believe the anthropic decision was made out of genuine security necessity rather than grievance-driven retaliation, high ranking officials could simply stop posting like this
Three months ago, @DeptofWar kicked @AnthropicAI out of our building—forever. Every passing day proves why that was the right move. 🇺🇸
Community note
This official statement is not accurate or truthful. The DOW didn’t kick out Anthropic “forever.” They invited Anthropic back when they launched the Mythos model — They even continued to use Mythos in high-stakes military ops. cnbc.com/2026/05/01/pen…

Tim Cook should be CEO of Anthropic. Change nothing — ship a new, better, faster Claude model every year. No drama. No surprises. Just relentless monoproduct execution focused on the brand.

Third, it's not even obvious to me what authority this is being taken under. If it's ECRA, It's not obvious to me that the law reaches Fable; if it's something else, we'll have to see what justification the administration has.

This precedent is going to backfire in ways that cannot be predicted by even the most trillionaire parameter MLPs
We fully support @POTUS and @SecWar in prioritizing national security and the security of our warfighters, DIB partners, critical infrastructure, international partners and allies. Some things are simply more important than revenue cycles, clickbait, and pre-IPO valuation. America First. Always. 🇺🇸

I would simply not fearmonger.
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…

Insane this is open weights... incredible work @ZyphraAI! Another banger for the open source community.

Codex loves to: verify the hashes one more time; guard this behind an opt-in gate

The damage Anthropic has done to their brand is irredeemable. It doesn't matter if they've walked this back, you can never trust a Claude. The moment it makes a mistake you'll wonder if it's silently screwing you over - did it mean to make that mistake? You can't trust it.
We’re rolling out changes to make Fable 5’s safeguards for frontier LLM development visible. Starting this week, flagged requests will visibly fall back to Opus 4.8—the same as our safeguards for cyber and bio. You will see this every time it happens. On the API, any flagged requests will return a reason for their refusal (coming to server-side fallback in the next few days). We wanted to deploy Fable 5 to our users quickly and safely. Visible safeguards can be probed, so they have to be robust, which takes time to get right. Invisible safeguards can be targeted more narrowly, allowing us to ship quickly with very few false positives. We went with invisible safeguards for this reason—and that was the wrong tradeoff. You should have visibility into the safeguards we have in place, and why. We’re sorry for not getting the balance right. Making the safeguards visible makes them easier to work around, so keeping them robust to jailbreaks will unfortunately mean more false positives while we improve the classifiers. We're also tuning our bio and cyber classifiers to trigger less often on harmless requests. We know this is frustrating and we’ll do our best to keep this period as short as possible. If you think a request has been mistakenly flagged: run /feedback in Claude Code, click thumbs-down on the fallback in Claude.ai or Cowork, or file the safeguard appeal form for API requests. Your reports help us tune these classifiers and we appreciate your feedback. support.claude.com/en/articl…

idk I'm just some guy on the internet, but I probably wouldn't conspire to monopolize through unfair and deceptive methods... i certainly wouldn't fucking tweet it out. I sure as shit wouldn't do it one week after filing my IPO. That wouldn't be very frontier intelligent of me. And then I absolutely would not indicate I post-facto understood the legal exposure of deceptively degrading product quality to manipulate free market competition by publicly walking back my "deception policy". I also wouldn't, in the same breath, violate {federal,state} consumer-protection regulations by requiring a fixed-period data retention. That wouldn't be superintelligent of me at all.

DiffusionGemma is our new experimental open model with up to 4x faster output on dedicated GPUs. Instead of predicting word-by-word, it generates entire blocks of text simultaneously. This lets the model self-correct and format complex markdown in real time.

Maybe I wasn't so wrong after all... I mean, there's no way they just turned the safeguards on with Fable without testing some of them out in Opus.
Replying to @danveloper
My worst interpretation is that Anthropic has put some steering into Claude Code to sabotage working with open models. We know from the source code leak that CC will do fake tool calls in certain circumstances, so that's not entirely off the table. Although, I choose to not accept that. In my head, I've considered this Anthropic's gift to open source - that it lets us do meaningful engineering on models. They're no real threat to their business model. No open weight model is going to compete with a 10T parameter Mythos. Maybe this is all a moment in time problem, and it's just a bug while Anthropic recoups capacity for scale and to get the next model out the door... that's what I'll choose to believe, for now.

This is remarkable! Fable 5: “create a visually interesting shader that can run in twigl-dot-app make it like an infinite city of solarpunk roads and towers with a visible breeze running continuously”
Fable: "create a visually interesting shader that can run in twigl-dot-app make it like an infinite city of neo-gothic towers partially drowned in a stormy ocean with large waves." "Make it better" All of this is procedurally generated.

I'll do a full write-up and push the repo up to GitHub, but I need a day or two to clean the code up... this started as a quest to build a lost-cost accelerator with the Hailo-10H for MacBook inference and I detoured to just run the full model on the Pi x.com/danveloper/status/2061…

I can't believe this works, but I got DeepSeek-V4-Flash (284B params) running on a Raspberry Pi 5 (8GB edition) at >1tok/s @ ~8W during full-tilt inference! It uses an untouched copy of @antirez's GGUF. Took 160 experiments over 5 days between GPT-5.5 xhigh and Opus 4.8 max.
