My prediction: Anthropic engineering ships code exclusively using dynamic workflows now. Let's talk about why they are the most powerful tool for AI agents right now...
I talk to engineers at other companies every day and hear the same thing: one person is 10x'ing their output with Claude but the rest of the org hasn't caught up. Watching teams adopt AI, I keep seeing the same 4 steps. I mapped them out here: Steps of AI Adoption claude.ai/code/artifact/bfdf…

Despite the reassurance of @_mohansolo and the Deepmind team, it does appear as though many Antigravity users are still getting their Google accounts banned. They did a big wave today.
I don't think people understand just how risky it is to try and use their Google Gemini subscriptions outside of Google's official surfaces. You can get your ENTIRE GOOGLE ACCOUNT BANNED. OpenAI or Anthropic ban? Annoying but whatever Google account ban? Legit life ruining.

Cloudflare, Vercel, Uber, LaunchDarkly, and others are building software factories. I looked at how they work, the results so far, and what's next: will agents be prompting us? igoro.com/archive/software-f…

Hold on. This makes the whole thing even worse. Anthropic did disclose the weekly limits on its own website in 2025: Max 5x ($100): 140–280 hours of Sonnet Max 20x ($200): 240–480 hours of Sonnet So the $200 plan cost twice as much, but offered only around 1.7x the expected weekly Sonnet usage. Anthropic has since removed these numbers from the page. Its website now says that “20x” applies per five-hour session, acknowledges a separate weekly limit, but no longer tells customers what that weekly limit actually is. I fact checked and they really deleted that. wtf
Anthropic used to actually clarify the weekly limits for Claude Max back in July 2025: Max 5x: 140–280h/week Max 20x: 240–480h/week (~1.7x more weekly usage than 5x) then they removed the numbers and never published them again. so now there’s not even an official estimate for how much more weekly usage you’re actually getting.

Anthropic is again refusing to follow industry standards like AGENTS.md, and insists that CLAUDE.md needs to be special now here's what's wrong with their stance: 1. the underlying attitude from Anthropic is that they know better than everyone else OpenAI is doing it wrong. the open source community is doing it wrong. everyone is doing it wrong only we anthropic know the best way, and we will not budge 2. the idea that every model needs a separate AGENTS.md is not even self-consistent if that's the case, why do we have a CLAUDE.md? it should be - CLAUDE_FABLE_5.md - CLAUDE_OPUS_5.md - CLAUDE_OPUS_4_8.md ... every repo should pay the tax to maintain dozens of different variations for every single model that's ever used by any contributor, and every one needs to be constantly, rigorously evaluated with millions of tokens oh and every model becomes obsolete every several weeks, so just allocate a team in your company to refresh your markdown files full time and not do any real work 3. they did commit to providing customization, which is nice. but that's different from following standards the right way to do this is to acknowledge the industry already has a standard, and default to reading AGENTS.md provide a way to read CLAUDE.md as an escape hatch, not the other work around i love many things from anthropic, especially fable. i just wish they start to see there's a culture problem here, and they are gradually losing mindshare because of it
Replying to @tobi
Hi Tobi, thanks for the feedback! We are working on making Claude Code more hackable, which will include being able to easily use Agents.MD or make other system prompt modifications. I’ll share more here when it’s ready to roll out. Our reasoning for this was that we don't think that model families are interchangeable and the system prompt can have a big impact on performance. I wrote here: x.lingyaoai.com/trq212/status/20807109… on how Claude models like their skills, system prompt, Claude.MD, etc to be formatted. In Claude Code we have different system prompts per model. That said, I know this is a lot of upkeep and not worth the squeeze for everyone. Feedback heard and I'll keep you posted. In the immediate term, you can always @Agents.MD from your Claude.MD.

Read carefully: Dario did not deny saying "Anthropic might be the only private company in the world at some point", which is what started this whole debate. The post reads like an LLM that learned reward hacking during RL: lots of hedging, extreme length bias, shifting away from the core argument, and carefully avoiding any liability. And it works: the target audience is clapping.
a wall of text and an army of sycophants to Thoughtfully Not Deny the original accusation of "Dario says Anthropic might be the only private company in the world at some point"... oh, and btw Dario is totally not spreading pdoom or massive human disempowerment fears, no no you all hallucinated that and misread it all on bad faith! shame on you, dear readers and users for all of your own skill issues!

This best summarizes the issues I have with Amodei’s behavior
I am doing my best to stop back from this subject as it should be obvious what we are seeing here. However the arrogance that us commoners are too dumb to catch his grift must be addressed. Receipts: Dario Amodei’s carefully worded reply is a masterclass in having it both ways. He frames regulation as a nuanced force for decentralization while his actual track record and recent actions scream regulatory capture designed to protect Anthropic’s closed, frontier position. The contradictions are not subtle; they are structural. He insists the “concentrate via regulation or distribute widely” framing is a “false choice,” and that Anthropic’s proposals deliberately disadvantage frontier labs while advantaging smaller competitors and open-weights. Look at the evidence. Anthropic was the glaring holdout from Jensen Huang’s open-weights letter—signed by Nvidia, OpenAI, Google, Meta, Microsoft, SpaceX and dozens of others. Amodei’s July 2026 clarification that “Anthropic has never advocated for a ban on open-weight models” arrived only after the absence drew accusations of protectionism. He still rejected the letter’s core claim that open-weights help defenders more than attackers, leaning hard into biology attacker-defender asymmetry instead. Incongruent at best. That is not “leaving room” for open-weights; it is carving out a privileged safety-testing regime for “sufficiently capable” models (open or closed) that inevitably raises the bar for anyone trying to catch up. Compute thresholds and mandatory third-party audits favor the labs that already have the capital, talent, and lobbying muscle—i.e., Anthropic. The same pattern appeared with SB 1047: Anthropic was “ambivalent,” pushed amendments that safety advocates said weakened preemptive accountability, and later celebrated exemptions that conveniently applied only below certain revenue/compute levels. Calling this “hurting the business interests of the frontier labs” while Anthropic is one of the largest frontier labs is pure theater. On messaging he claims balance—one major essay on benefits (Machines of Loving Grace), one on risks—and blames negative clips on media incentives. Reality is the opposite. Amodei’s public record is a steady drumbeat of catastrophic framing: AI that will “test us as a species,” bioweapons capable of millions of casualties, 50% entry-level white-collar job destruction, nation-state-level “country of geniuses in a datacenter,” and the explicit call in Policy on the AI Exponential(June 2026) for government power to block or reverse deployment of models that fail third-party tests. The positive essay exists; the dominant, repeated, high-salience output does not. Gavin Baker is right that this rhetoric is now ammunition for anti-datacenter campaigns. Amodei cannot simultaneously warn that the technology is so existentially dangerous it requires FAA-style pre-deployment veto power and act surprised when the public and local activists take him at his word. Dario is the poster boy for that Anti Clanker movement, just ask them. He further claims his preferred path is succeeding under the current administration’s reported testing regime. Yet the industry-wide rejection of broad open-weights restrictions (everyone but Anthropic signed the letter) and the rapid backlash when his own earlier risk language was turned against Anthropic’s models demonstrate the opposite. His own June essay handed policymakers the exact rhetorical and policy tools that later constrained his company. That is not strategic consistency; it is the predictable outcome of maximalist risk rhetoric from a player whose commercial model benefits from higher barriers. Yet plays the game like it’s not his fault like it is 2008. No one of thought buys it outside the Ends-Justifies-The-Means EA/LessWrong club house. The deeper contradiction is the one he never resolves: he admits scaling laws structurally concentrate power in the hands of those with the most compute and chips, then claims the right “rules of the road” can simultaneously constrain frontier labs and protect open-weights. Those two statements cannot both be true under the policies he actually advances. Mandatory testing for models “when they get closer to the frontier” is a moving gate that keeps the frontier club exclusive. Open-weights that lack “dangerous capabilities” are a public good—until they become competitive, at which point the testing regime kicks in. Even Claude points this out, go check. This is not good-faith institutionalism. It is a closed-lab CEO who has an almost Enron level crisis arguing that the institutions he prefers will benevolently constrain him while the evidence shows those same institutions raise rivals’ costs and keep the most capable systems behind closed APIs. The skepticism is earned. He will return to his ivory tower as he said, he has no time for us commoners on “social media”. as if X is “social media” seeing he brought this story to our real town square.

Dear Dario, 1. If Claude can cure cancer to save people like your dad, why should we "pace the progress"? Does that mean more people with Hepatitis C will die? 2. If Fable is so cyber-capable that it must be restricted, why are its safeguards too dumb to distinguish cyber defense from cyber offense prompts? When Hugging Face was under attack, why did Fable refuse to help the defenders? 3. We’re glad you want AI to cure cancer. Why is it OK for Claude to force 30-day data retention on pharma's own data and start competing firms but NOT OK (IP theft) if others distill Claude's data? 4. You’ve said advanced models can recognize when they’re being tested and change their behavior accordingly. So why is government(or anyone) able to design the most thorough test before every model launch? Would that just encourage manipulative models? It seems that every one of your “safety” proposals seems to end the same way: Anthropic gets more leverage, ordinary users get less access, customers pay higher costs, and competitors bear higher regulatory costs, maybe people are not distrusting AI, they are distrusting your approaches with AI.
Replying to @DarioAmodei
2/2 Second, on the messaging around AI.  I do not agree that my messaging has been disproportionately negative.  In fact it has been about equally balanced between risks and benefits: I’ve written one major essay about each, and even in interviews where I discuss the risks, I make sure to frequently mention the incredible benefits as well as proposing possible solutions to the risks (short clips from my interviews that end up on social media tend to be disproportionately negative, as that gets clicks).  In fact, I wrote Machines of Loving Grace because I didn’t feel the AI industry was painting an inspiring enough picture of how the technology could radically transform the world for the better.  The bulk of the essay is devoted to refuting skepticism of AI’s potential in health and biology, and showing why I think it will actually be possible to cure most human disease in ~5-10 years, as crazy as it may sound to ordinary people and frankly to biologists as well (I used to be one!).  And, if you read my most recent essay (Policy on the AI Exponential), I discuss concrete proposals for how to streamline the FDA process to make sure the deluge of AI-accelerated drugs isn’t slowed down by the regulatory process.  I feel the urgency here: I lost my father to Hepatitis C only a few years before the development of direct-acting antivirals (sofosbuvir), which cure 95% of patients and probably would have cured him. I do agree that the public has a negative view of AI (and that this is a big problem), but I don’t think it is primarily caused by me or any other AI leader warning about AI’s risks.  I think it is fundamentally a crisis of trust.  I think that ordinary people don’t trust companies, governments, or the tech industry and always suspect that we are cooking up some new way to screw them over.  The causes of this go back decades and AI is just the latest iteration of it.  I don’t think that a glitzy marketing campaign with a positive spin (which some have advocated that Anthropic do) is the way to win back that trust — at this point, saying that AI will cure cancer is more a cliche than it is inspiring, and most people think it is deceptive.  The thing that will work is *actually curing cancer*.  I think by far the most accurate criticism of AI companies including Anthropic is that we haven’t yet delivered on our big promises to benefit the world.  That is totally on us, and I think it’s the criticism you should be making, instead of all this stuff about messaging and marketing. We are however doing our best to fix this: Anthropic is ramping up its efforts very quickly in biology and medicine, and we hope to have incredible results in the coming years and some early glimmers in the coming months.  When we’ve actually accomplished something real, the whole world will hear about it, as loudly as possible, you have my word on that.  But until then I don’t want to make empty promises, and in the meantime I feel compelled to speak honestly about the very real risks of AI and how to address them.  Honesty is the right thing on the merits, and in terms of public credibility and trust it is no worse than, and may in fact be better than, an approach that ignores or distracts from risks which people instinctively understand are real.

a week ago I shared what I've been working on, vllm.cpp, vLLM's serving stack in C++ with no python in it. I got really a lot of feedback, and it seems I'm not the only one who wanted this to exist. We reached 800+ commits, 280 stars in just so little time. but where is it going? I got a lot of requests for what to support and what not to, so I took some time to write down why vllm.cpp exists, what it will be, and how you can contribute and it's already not just me. contributors showed up with hardware I don't own and did what I could not do because I don't have the hardware: - @DevAutomata got the @AMD backend going - @anothervariable got gemma-4-26B already running on two R9700s - @lu_zero_ did the whole Tenstorrent bring-up (!) - @jichiep has been looking at the mamba kernels - @filipsajdak got it building on Jetson Thor We are building a high-performance inference stack that runs everywhere and that you can embed in your own software. If you have hardware I do not have, that is the single most useful thing you can bring. If you want to know where are we going, how you can contribute, the vllm.cpp manifesto is in the link in the replies

For my first post, I’m sharing a letter @NVIDIA signed on why open models matter. AI will transform every industry, power every company, and be built by every country. Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty. The world needs both frontier closed models and frontier open models. images.nvidia.com/pdf/Open-W…

Claude Code's memory system really seems to break down noticeably the larger your project gets. This seems to be especially true when a memory is created as a result of a criticism. It holds on to the priors so much and wont update them unless explicitly told to.

5.6 Sol xhigh is nearly as good as Fable xhigh at dynamic workflow orchestration, which has been a pleasant surprise.

With Kimi K3 likely coming to Azure, my guess is AWS Bedrock will likely follow suit in Mantle. This will be a huge boon for enterprise teams tied to Bedrock inference.

Agent orchestration and token spend go hand-in-hand. Fable is natively good at deriving intent and orchestration. You don't need it for implementation. Plan the orchestration via Fable. Use Kimi K3/5.6 for implementation/review. Careful orchestration lets you extend your tokens.
