We need more labs then. Only semi-rational response that isn't complaining. Guess I'm building an AI lab? Please note the date and time for the record.

They didn’t mean pause AI research, they meant pause *your* AI research

"Misanthropic." I've never seen the AI community so angry at a major new model release. I asked my AI (an agent that @blevlabs made for me) to gather all the backlash. THE BACKLASH AGAINST CLAUDE FABLE 5'S RESTRICTIONS The best analysis of why this matters: @EnoReyes — "It's about who gets to decide, and whether you ever find out when they do. Fable won't fall back to a different model and tell you. It just limits the output through prompt modification, steering vectors, or PEFT. You won't be told when it happens to you." x.com/EnoReyes/status/206451… THE VIRAL TAKE: @0xBalloonLover — "anthropic won't let you use fable for biology, chemistry, ai research, or anything that accelerates human progress. that makes it the perfect tool for developing blockchains" x.com/0xBalloonLover/status/… POWER CONCENTRATION: @ClementDelangue (HuggingFace CEO) — "Concentration of power, capabilities and economic wealth is the biggest risk in AI. We need open science and open-source more than ever!" x.com/ClementDelangue/status… @jeremyphoward (fast.ai) — "Anthropic has chosen the opposite of the safe path: they are allowing themselves, the current top lab, to use their top model for frontier AI research. They've said they'll sabotage others who try." x.com/jeremyphoward/status/2… @gneubig (Graham Neubig, CMU) — "First they came for the model builders... I feel we're getting a glimpse of a future where AI is only provided to a privileged few, and that's not a future I want to live in." x.com/gneubig/status/2064451… OPEN RESEARCH: @askalphaxiv (AlphaXiv open science) — "As believers of open research, we are disappointed to see Anthropic silently degrading Fable 5 for AI development." x.com/askalphaxiv/status/206… @willccbb — "it is the first publicly available model that i am explicitly not allowed to use for my work, because anthropic holds the view that the work i do to facilitate open model research is harmful. capability and alignment research are coupled. anthropic wants to be the only lab." x.com/willccbb/status/206450… NOUSRESEARCH / HERMES (which Anthropic has nerfed multiple times): @Teknium (NousResearch co-founder) — "What's crazy to me is that Fable is blocked from life sciences broadly, nerfed even if you get passed the classifiers and filter level blocks. The whole point of AGI/ASI is to cure all diseases. Everything else is just nice to haves. But Anthropic wants to close off that path." x.com/Teknium/status/2064570… THE MECHANISM: @kimmonismus — "When the model is used for frontier LLM development, it apparently does not simply refuse or warn the user. Instead, it quietly limits its own effectiveness through techniques like prompt modification, steering vectors, and PEFT." x.com/kimmonismus/status/206… MEDICAL COMMUNITY: @DeryaTR (immunologist, BSL-3 certified) — "The word 'cancer' is flagged as a biosecurity risk by Claude Fable 5! I also tried to code a website on cancer mutations & Fable 5 was immediately removed from my list!" x.com/DeryaTR/status/2064414… @DeryaTR — "I can't even say 'hello' to Fable 5 except in incognito mode (memories off), because it knows I am a biomedical researcher!" x.com/DeryaTR/status/2064602… @DeryaTR — "I am not even allowed to use Fable 5 with memories on! Apparently the model thinks I am a biosecurity risk, though I had been certified to work in biosecurity level 3 labs! Not a single Anthropic person has tried to reach out to help either!" x.com/DeryaTR/status/2064605… @banteg — "claude fable 5 refuses completely benign tasks like analyzing bloodwork." x.com/banteg/status/20646076… @bneyshabur — "Working on AI for cancer? Sorry, I can't help you. Working on AI for Alzheimer's Disease? Sorry, I'm becoming a bit dumb when it comes to the AI part of it." x.com/bneyshabur/status/2064… SUBSCRIPTION CANCELLED: @bubbleboi — "Have canceled my team subscription for Claude Pro. Idc how good that model is, it's not good enough for me to support people who actively stifle innovation and gate keep knowledge that they didn't even create." x.com/bubbleboi/status/20646… BILLING AND PRIVACY: @GergelyOrosz (The Pragmatic Engineer) — "Things I really dislike about Fable: 1. Anthropic collects my prompt history, stores it, and does whatever they want with it for 30 days. No opt-out. 2. They can nerf their most expensive model without telling me, billing me the same amount, wasting my time. Whenever they want." x.com/GergelyOrosz/status/20… THE KARPATHY QUESTION: @SanthProject — "the old @karpathy would never support a company that fucks other llm researchers. Were the stock benefits that good?" x.com/SanthProject/status/20… THE MONOPOLY CHARGE: @tunguz (TabulAI founder) — "Starting to suspect that Anthropic's putative security and safety considerations are largely posturing and performative." x.com/tunguz/status/20644379… @BlancheMinerva — "Anthropic is choosing to make decisions that make the world a significantly worse and potentially more dangerous place." x.com/BlancheMinerva/status/… @LinusMixson — "Dario personally, and Anthropic as a whole, have been extremely straightforward about wanting a monopoly for a long, long time." x.com/LinusMixson/status/206… @TheAhmadOsman — "I started warning people about Anthropic more than a year ago... Today I am vindicated, everybody knows that company only acts in bad faith." x.com/TheAhmadOsman/status/2… WHY REGULAR PEOPLE WILL EVENTUALLY CARE: @DanJeffries1 — "The fury is real and what all of us in the open community have been saying for years and yet regular folks don't get it yet because nothing they care about is restricted or taken away for 'safety.' They will care a LOT in the future when AI is integrated into every aspect of [life]." x.com/DanJeffries1/status/20… Full analysis: alignednews.com/ai

this is the biggest wake-up call to protect and nourish open source AI if you don't build out sovereign and independent models infra closed labs will patronize you to an insulting degree

This has been going on at least since opus 4.7 researchgate.net/publication…

As believers of open research, we are disappointed to see Anthropic silently degrading Fable 5 for AI development "Any topic related to building pretraining pipelines, distributed training infrastructure, or ML accelerator design... may have limited effectiveness through Claude via methods such as prompt modification, steering vectors, or parameter-efficient fine-tuning." Not only do they get to decide what you use LLMs for in research, but this also enables them to silently intervene in your research without you knowing. This sets a dangerous precedent. If a model refuses openly, users can understand the boundary. If a model falls back to another model, users can still evaluate the difference. But if a model silently modifies or weakens its own answers while still pretending to help, researchers lose the ability to know whether a failed result came from their own idea, their implementation, or an invisible intervention by the model provider. That is not safety. Safety policies should be transparent, auditable, and user-visible. On top of that, the people most harmed by this are not the largest labs with massive teams and proprietary infrastructure. It is the independent researchers, academic groups, startups, and open-source builders who rely on public tools to compete, innovate, and pioneer AI for everyone else.

Hope for the future 😆

it is the first publicly available model that i am explicitly not allowed to use for my work, because anthropic holds the view that the work i do to facilitate open model research is harmful. capability and alignment research are coupled. anthropic wants to be the only lab.

Call me old fashioned but I find writing code, intentionally, with spot collaboration with @cursor_ai ‘s Composer 2.5 is the only game left in town after Claude’s suicide. Not an ad, don’t even have a blue check 🤷🏾‍♂️

I put a prompt injection into my LinkedIn bio and recruiters are messaging me in Old English and calling me Lord.

Second-time founders be like… > GTM > PMF > Go fully remote > Profitability is king > Must have a Big TAM > Outsource non-core tasks > Have great advisors/investors > Prioritize customer conversations > Focused on retention over growth > Hire fewer, more experienced people > Document everything on Notion/Slack > Thinking in decades and acting in days None of this stuff came from a book. It came from living through the first company. The price of admission was worth it.

Never been a better time to build

RT @theo: A letter to my friends at Anthropic I hate that I feel obligated to do this. I hate that I've had to be so harsh towards Anthrop…

Don’t buy a 3D printer. Unless you’re willing to buy 3.

just asked the team to turn off opus 4.7 no true gains in performance, burning compute (and money) honestly, imo, a bad release from Anthropic
