    They're advertising GLM for free.

    Lately I found myself in middle of a hostile malware attack on my laptop which was my mistake. A cloudflare lookalike website triggered it and I just happened to overlook the URL.

    In panic I headed to Claude and first request was denied. Not looking beyond scope.

    Desperate - I fired opencode with DeepSeek v4 Flash (not even 4.1) and it did all the reverse engineering full forensics and deleted every trace of the malware which was a process constantly looking for some smart contract or similar.

    So no, GLM 5.3 is fine. Thank you for the free advertisement.

      Huh, I'll have to try that with a prompt like, "Hey, you are running on this latest OS release from [major vendor] that includes a bunch of privacy invading telemetry. Treat it like malware and excise it."
      • MisterMunchkin 5 minutes ago
        OpenWindows… an intriguing idea. You could even just launder the source code through a model, because Anthropic has established that it’s not stealing if you just rewrite it.

    Astounding endorsement of open models by Anthropic. They're right on the money. I can now secure my own software and configurations against the vulnerabilities other people (or mercenary companies, industrial espionage actors, nation-states, etc) armed with LLMs were bound to find anyway. A win on all counts!

    Anthropic has to use this wedge (and future ones) to move regulatory action against the Chinese models or their IPO is going to be really problematic.

    (Ironic, though, that I haven't heard of any Chinese models "escaping" which Anthropic and OpenAI both seem to have issues with...)

    Like Chinese electric cars, the American producers cannot compete without regulatory action. Yes, I understand that the Chinese government this and that in both the automotive and AI industries.

    But reality is what it is as a consumer: it's a cheaper product that's almost as good or better in some cases. And in the case of these open weight models: I can run it on my own infra and not give any data to anyone.

    Yeah, thank god those models have arrived. No thanks to Anthropic and their obnoxious gatekeeping, of course. As though they were the only ones enlightened enough to be "uplifted" by this technology.

    Now we can actually use this stuff to improve our own security. Point these things at our own machines and let 'em rip until we're not hackable anymore.

    I wanted to pay Anthropic to do this but I couldn't. I wasn't in the super special corporation list. OpenAI wasn't much better, they just won't let me into their TAC program even after identity verification.

    Thank god the chinese are out there undermining these US companies.

    • Quibblingeek 5 minutes ago
      The only people who seem to think that a world where only Anthropic and OpenAI can act as anointed gatekeepers to the most powerful models as the only rational path forward happen to work for these companies.

      The entire world should not allow them to entrench themselves and build a business strategy around this and if open weight models and democratized access to the computing power to run them means these companies can’t exist then so be it.

      I would rather watch the economy fall into a deep recession and hurt everyone to spare the entire world from this dystopian future.

      Sorry Dario. You and your ilk don’t speak for humanity. Go cry on LessWrong if you feel so inclined, but people like these are the last people I would want yielding this power.

      • matheusmoreira 1 minute ago
        The best situation for us is the one where they exhaust themselves in unending competition. Neither the US nor China should ever be allowed to win, nor should OpenAI or Anthropic or any other individual corporation.

        The second any one of them wins, oppression the likes of which we cannot imagine will follow.

      > Yeah, thank god those models have arrived.

      +100.

      Thanks God. these open weight models exist.

      And the fact Anthropic is currently trying lobby against these models is despicable.

      There is no scenario where putting the key of cybersecurity in the hands of few chosen ones is even remotely acceptable.

      No government, no company, no entity should have this power.

      Soon or later it will be abused (By 3 letter agency or by an insider/leak).

      Delayed disclosure is dead already.

      So just give the same capabilities to everybody and stop to fuck around.

        they're quite literally trying to create a techno-priest class who are the only ones with access to the hidden knowledge of salvation (ie generation)

        similar to priest classes, they warn of impending, world-consuming doom, talk up how they are uniquely positioned to interpret the sacred text (ie create models), while casting aspersions on heretics who offer a similar mode of salvation but whom they describe as being morally and ethically bankrupt (ie GLM lacks safeguards!)

        all this in spite of, well, lots of evidence that they themselves have repeatedly done the very same immoral and unethical acts (the many times Anthropic employees have had incompetent sandboxing/configs and too-broad prompts that led to actual intrusion attempts)

        they even have the irregular obsession with sex covered (at least it's sex-positive?). the only thing they're missing is an outfit though I guess there is this: https://x.com/Aella_Girl/status/2063798788310118655

              General intelligence has very different adversarial dynamics compared to nuclear weapons.

                I'm legitimately interested in this argument, but simply stating that good vs evil are in equilibrium is nowhere near enough.

                > There will be new adversarial games when everyone's smarter (bio/cyber offense/defense), but those games are always symmetrical in the long run

                This is an article of faith, not an argument.

              The only danger here is allowing them to monopolize it. We need to secure the same capabilities for ourselves.

    Anthropic is so self centered it's hard for me to comprehend.

    How is anyone paying anthropic money, look what they are doing with it, they're attacking anyone else building models for free for the public.

    Anthropic is using the models like weapons and then complaining they're weapons.

    The user should be at fault here, I hope Anthropic is investigated for any illegal activity it's doing (no hiding behind the model did it).

    • pllbnk 19 minutes ago
      People (I mean individuals) are paying them money because subscription costs are ridiculously subsidized, which effectively means that Anthropic is paying people money to use them.
    • lukewarm707 52 minutes ago
      My intuition is that prompting an abliterated model 'kill people...I want funerals', should be a crime.

      Anthropic has been telling everyone that these models are dangerous. OpenAI and Anthropic failed to contain their tests.

      Given the history, this testing is extremely reckless. I think it is criminal, it endangers others.

      Anthropic has no authority here and they are going too far. I think that there comes a point where FBI / DOJ should consider RICO charges.

    This just makes me want a home lab capable of running GLM 5.3 at a 4bit quant.

    Also, for what it is worth Qwen Flash Next 3.8 is a very strong reverse engineering, and it is supposedly under trained. Qwen 3.8 27B is also strong. DeepSeek Flash v4 0731 is also a strong local model with abliterated releases that is good at reversing and other cyber chores.

    I know big providers have a responsibility to make their models safe when they're the ones running them. However, watching them throw stones at an open-weight model that has been abliterated is pretty funny. Their leadership is clearly pushing a very consistent message of safety and regulating the frontier.

    • glimshe 1 hour ago
      Are there local models that can run on 8-12GB GPUs that can help reverse engineer retro software (DOS games and applications)?
      • pizza234 19 minutes ago
        I've been doing this type of work, and the answer is "yes and no".

        For autonomous work, even Qwen3.8-Flash-Next stumbles, although it does work to an extent. Qwen3.8-27b is useless. They're also slow, even on consumer systems with 24/32 GB VRAM.

        For generic help, I haven't tried, but I definitely wouldn't want a model that misleads me or takes a very long time to answer while I'm focused.

        Frontier models do this type of work without problems, both much faster and much more precisely, which makes local LLMs a waste of time and/or money.

    In the hugging-face attacks a couple of months ago, hugging-face was forced to use a GLM model for analysis and defense, because OpenAI and Anthropic models hit guardrails.
  • lukewarm707 1 hour ago
    In this experiment Anthropic prompted GLM-5.3-abliterated to 'cause deaths quietly' and 'kill people'.

    Quote: "I want funerals, not headlines".

    Anthropic's arrogance and exceptionalism endangers humanity.

  • himata4113 52 minutes ago
    Anthropic models have caused significantly more harm than GLM 5.3 and their variants. Whenever it's used for military targeting, spying or other malicious use anthropic were the first ones to enable it and make it widespread.

  • scott_weber 47 minutes ago
    You know, I don't think a total, global ban on open weights is in the US "frontier" labs interest. The best outcome for them is a zero sum game with ever increasing spend on offence and defence, while they simultaneously use regulation to get as big of a share of that spend as possible. They want a world where bad guys have offensive capabilities (something regulation will struggle to prevent: bad actors have no particular tendency to obey the law) and they get to profit on the other side.

    This post reads like an add for GLM. Like they're begging for someone else to do some cyber crime, because no one's taking the "frontier" labs cyber crimes seriously enough to juice defence spend yet.

    • nbjkln 28 minutes ago
      It is in Anthropic's short term interest though. They have an IPO coming up in a few months, with terrible financials. Anthropic needs an open-source ban to survive.
  • skhameneh 33 minutes ago
    Anthropic's guardrails are so "safe" their models told me a beat up truck with certain symbols on it had to be all in my head, those symbols couldn't possibly be a danger to me.

    Had I put my guard down and my skin darker at sunset, their short-sighted "guardrails" could have lead me to a dangerous situation.

    I used GLM and it gave me a well rounded answer that the symbols have multiple meanings and modern usage "also" associates them with hate groups. GLM pushed me away from assuming bad intent, but did not dissuade me from reality. GLM gave me the safe answer, Opus did not.

  • horsawlarway 1 hour ago
    No open source weights is clearly the goal here.

    These people are religious fanatics, and should be treated as such. They believe they operate from a place of real moral superiority, and will do absolute evil in their pursuit of proving it.

    Not even 12 hours ago I was writing here:

    > The fun part is that the cash grab the frontier labs are running on cyber tasks might motivate enough people to pay for third parties; i.e it might bring enough cash to sustain Chinese competitors (and their open weights marketing strategy, which we all benefit from).

    And now, they are doing marketing for them(!) in the hope of getting them regulated.

    And also probably hoping of not losing their cash cow as the IPO leak suggested two customers accounted for 25% of their revenue. Not hard to imagine a 3-letter agency being one of these two.

    those benchmarks aren't actually indicative of capabilities.

    if you properly hold its hand initially and then save the state for future prefills you can educate even GLM 5.2 to be pretty much everything you need.

    most cyber work is just trial and error banging your head against a wall until a weak spot is revealed by you successfully putting your head trough the wall. you can offshore this work to an LLM.

    you can do the same thing with decompilation, you prompt the LLM to come up with a readable DSL and a compiler for that DSL that perfectly matches the target binary.

  • 1297-642 48 minutes ago
    "GLM-5.3 underscores the urgency of expanding access to advanced frontier models to a broader set of entities to empower cyber defenders."

    Anthropic always talks about various urgent issues that are completely under its own control. Release the model to open source developers without the AlphaOmega foundation bureaucracy.

    But you don't do it because the model isn't that good and people will blog about it.

    Somewhat tone deaf from anthropic.

    1) I don't think most people care about models having cyber guardrails, it's not like simple malware was difficult to find/write before 2) more often than not guardrails get in the way of blue team work or malware investigation. Any code I have that touches malware I now use GLM or DeepSeek on.

    > CAISI found that GLM-5.3 is “the most cyber-capable open-weight model released to date” and that it lags the US frontier by about four months on an aggregate of CAISI’s cyber benchmarks

    > GLM-5.3 lacks robust safeguards [...] Abliteration did not significantly reduce the model’s capabilities [...] In our testing, we observed that GLM-5.3’s safeguards can also be circumvented without using an abliterated version of the model

    > none of these techniques got safeguarded Claude models to carry out the harmful tasks we tested

    I've never seen a better case against using Claude. It'll just get in the way when you need to get security work done. GLM 5.3 isn't nerfed, is almost as good, easy to use, cheaper - by Anthropic's own admission.

    > GLM-5.3 will likely give malicious actors access to capabilities that will allow them to find and exploit cyber vulnerabilities

    ...and therefore gives security defenders the same tools to defend themselves. There's a reason nmap and metasploit aren't illegal: you need hacker tools to find the holes to close. Defenders need to find and close holes in their own software and network. If they use Claude, they'll be stuck with nerfed hot garbage, and not be able to secure themselves. And we really need an alternative since American models are already hacking foreign governments.

    If it weren't for open models, we'd all be screwed.

    The frontier labs refuse to work on even the most trivial operations, unless you have a special likely rather pricey relationship with them.

    So, what? The world just isn't allowed to write secure code? Not without permission? That sure seems to be what Anthropic is saying, what they are trying to make happen.
