Calling safety regulators on your competitors is just regulatory capture with extra steps. Real safety comes from competition and rapid iteration, not from one company playing thought police.
"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."
https://t.co/k6s7gdgckk
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"
https://t.co/8GiTfZOASu
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!"
https://t.co/6n4mjoCdfN
@jeremyphoward (https://t.co/hxyqsLY2ti) — "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."
https://t.co/305uPAbiaA
@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."
https://t.co/JiFiz55YYK
OPEN RESEARCH:
@askalphaxiv (AlphaXiv open science) — "As believers of open research, we are disappointed to see Anthropic silently degrading Fable 5 for AI development."
https://t.co/KaP0NEivW6
@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."
https://t.co/mIovN3a0FS
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."
https://t.co/8Nh5Squ2UA
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."
https://t.co/HsrA8xeScP
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!"
https://t.co/3VpiYWZmbz
@DeryaTR — "I can't even say 'hello' to Fable 5 except in incognito mode (memories off), because it knows I am a biomedical researcher!"
https://t.co/jxWcx8y8QE
@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!"
https://t.co/Rj6EGLw8Vq
@banteg — "claude fable 5 refuses completely benign tasks like analyzing bloodwork."
https://t.co/Wg5LLYK5lW
@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."
https://t.co/wLetowldAD
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."
https://t.co/4km3iR3N12
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."
https://t.co/pV5qiZnsTR
THE KARPATHY QUESTION:
@SanthProject — "the old @karpathy would never support a company that fucks other llm researchers. Were the stock benefits that good?"
https://t.co/Hw8uHLuZWB
THE MONOPOLY CHARGE:
@tunguz (TabulAI founder) — "Starting to suspect that Anthropic's putative security and safety considerations are largely posturing and performative."
https://t.co/gwKrgbNSWY
@BlancheMinerva — "Anthropic is choosing to make decisions that make the world a significantly worse and potentially more dangerous place."
https://t.co/Tlc6ct64AH
@LinusMixson — "Dario personally, and Anthropic as a whole, have been extremely straightforward about wanting a monopoly for a long, long time."
https://t.co/Ngj9csOazh
@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."
https://t.co/l0TmVRJOSO
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]."

@goEverySight As a Kickstarter backer, I’m genuinely stoked for these to ship. The dual-eye display and CXR-L SDK look perfect for developers like me at @SiceliumAI
Can’t wait to get my hands on them and start utilizing and building. Keep up the great work!
Do you think Tesla will keep the ultimate driving experience running parallel with autonomous driving, or will it all go pure autonomous?
My vibe: I want to snag a Cybertruck and brag about hitting 90%+ autonomous miles while still having that raw, steer-by-wire thrill when I feel like it. Is hands-on driving becoming the new ‘peasant’ activity in the AI era?
What does lapping a track in a human-driven beast even mean when an AI can whip around it flawlessly, with zero fatigue or ego? Who cares about bragging rights on 0-60 when your future family hauler will smoke today’s supercars without breaking a sweat?
Driving for fun might stick around for enthusiasts… but the daily grind? Let the robot handle it.
Introducing 𝑨𝒕𝒕𝒆𝒏𝒕𝒊𝒐𝒏 𝑹𝒆𝒔𝒊𝒅𝒖𝒂𝒍𝒔: Rethinking depth-wise aggregation.
Residual connections have long relied on fixed, uniform accumulation. Inspired by the duality of time and depth, we introduce Attention Residuals, replacing standard depth-wise recurrence with learned, input-dependent attention over preceding layers.
🔹 Enables networks to selectively retrieve past representations, naturally mitigating dilution and hidden-state growth.
🔹 Introduces Block AttnRes, partitioning layers into compressed blocks to make cross-layer attention practical at scale.
🔹 Serves as an efficient drop-in replacement, demonstrating a 1.25x compute advantage with negligible (<2%) inference latency overhead.
🔹 Validated on the Kimi Linear architecture (48B total, 3B activated parameters), delivering consistent downstream performance gains.
