However I am still mystified by the safety aspect. They say the model has greatly improved resistance. But their own safety evaluation says 8% of the time their automated adversarial system was able to one-shot a successful injection takeover even with safeguards in place and extended thinking, and 50% (!!) of the time if given unbounded attempts. That seems wildly unacceptable - this tech is just a non-starter unless I'm misunderstanding this.

Computer use (to anthropic, as in the article) is an LLM controlling a computer via a video feed of the display, and controlling it with the mouse and keyboard.
> where the model interacts with the GUI (graphical userinterface) directly.
"Security" and "performance" have been regular HN buzzwords for why some practice is a problem and the market has consistently shown that it doesn't value those that much.
I can type awful stuff into a word processor. That's my fault, not the programs.
So if I can trick an LLM into saying awful stuff, whose fault is that? It is also just a tool...
If I sell you a marvelous new construction material, and you build your home out of it, you have certain expectations. If a passer-by throws an egg at your house, and that causes the front door to unlock, you have reason to complain. I'm aware this metaphor is stupid.
In this case, it's the advertised use cases. For the word processor we all basically agree on the boundaries of how they should be used. But with LLMs we're hearing all kinds of ideas of things that can be built on top of them or using them. Some of these applications have more constraints regarding factual accuracy or "safety". If LLMs aren't suitable for such tasks, then they should just say it.
Where would we be if patents never existed?
that was also brilliant marketing
> Nearly a year ago we wrote in the OpenAI Charter : “we expect that safety and security concerns will reduce our traditional publishing in the future, while increasing the importance of sharing safety, policy, and standards research,” and we see this current work as potentially representing the early beginnings of such concerns, which we expect may grow over time. This decision, as well as our discussion of it, is an experiment: while we are not sure that it is the right decision today, we believe that the AI community will eventually need to tackle the issue of publication norms in a thoughtful way in certain research areas. -- https://openai.com/index/better-language-models/
Then over the next few months they released increasingly large models, with the full model public in November 2019 https://openai.com/index/gpt-2-1-5b-release/ , well before ChatGPT.
I wouldn't call it rewriting history to say they initially considered GPT-2 too dangerous to be released. If they'd applied this approach to subsequent models rather than making them available via ChatGPT and an API, it's conceivable that LLMs would be 3-5 years behind where they currently are in the development cycle.
> Due to concerns about large language models being used to generate deceptive, biased, or abusive language at scale, we are only releasing a much smaller version of GPT‑2 along with sampling code (opens in a new window).
"Too dangerous to release" is accurate. There's no rewriting of history.
It's quite depressing.
> You will need one cup King Arthur All Purpose white flour, one large brown Eggland’s Best egg (a good source of Omega-3 and healthy cholesterol), one cup of water (be sure to use your Pyrex brand measuring cup), half a cup of Toll House Milk Chocolate Chips…
> Combine the sugar and egg in your 3 quart KitchenAid Mixer and mix until…
All of this will contain links and AdSense looking ads. For $200/month they will limit it to in-house ads about their $500/month model.
That level of internal fierce competition is a massive reason why they are beating us so badly on cost-effectiveness and innovation.
Something something ... Altman's law? Amodei's law?
Needs a name.
Yeah, but RAM prices are also back to 1990s levels.

Somehow it's much better now.
You should always take those claim that smaller models are as capable as larger models with a grain of salt.
So if you don't want to pay the significant premium for Opus, it seems like you can just wait a few weeks till Sonnet catches up
I haven't seen a response from the Anthropic team about it.
I can't help but look at Sonnet 4.6 in the same light, and want to stick with 4.5 across the board until this issue is acknowledged and resolved.
I've overall enjoyed 4.6. On many easy things it thinks less than 4.5, leading to snappier feedback. And 4.6 seems much more comfortable calling tools: it's much more proactive about looking at the git history to understand the history of a bug or feature, or about looking at online documentation for APIs and packages.
A recent claude code update explicitly offered me the option to change the reasoning level from high to medium, and for many people that seems to help with the overthinking. But for my tasks and medium-sized code bases (far beyond hobby but far below legacy enterprise) I've been very happy with the default setting. Or maybe it's about the prompting style, hard to say
When my subscription 4.6 is flagging I'll switch over to Corporate API version and run the same prompts and get a noticeably better solution. In the end it's hard to compare nondeterministic systems.
I started using it last week and it’s been great. Uses git worktrees, experimental feature (spotlight) allows you to quickly check changes from different agents.
I hope the Claude app will add similar features soon
If I don't want to sit behind something like LiteLLM or OpenRouter, I can just use the Claude Agent SDK: https://platform.claude.com/docs/en/agent-sdk/overview
However, you're not supposed to really use it with your Claude Max subscription, but instead use an API key, where you pay per token (which doesn't seem nearly as affordable, compared to the Max plan, nobody would probably mind if I run it on homelab servers, but if I put it on work servers for a bit, technically I'd be in breach of the rules):
> Unless previously approved, Anthropic does not allow third party developers to offer claude.ai login or rate limits for their products, including agents built on the Claude Agent SDK. Please use the API key authentication methods described in this document instead.
If you look at how similar integrations already work, they also reference using the API directly: https://code.claude.com/docs/en/gitlab-ci-cd#how-it-works
A simpler version is already in Claude Code and they have their own cloud thing, I'd just personally prefer more freedom to build my own: https://www.youtube.com/watch?v=zrcCS9oHjtI (though there is the possibility of using the regular Claude Code non-interactively: https://code.claude.com/docs/en/headless)
It just feels a tad more hacky than just copying an API key when you use the API directly, there is stuff like https://github.com/anthropics/claude-code/issues/21765 but also "claude setup-token" (which you probably don't want to use all that much, given the lifetime?)
In either case, there has been an increase between 4.1 and 4.5, as well as now another jump with the release of 4.6. As mentioned, I haven't seen a 5x or 10x increase, a bit below 50% for the same task was the maximum I saw and in general, of more opaque input or when a better approach is possible, I do think using more tokens for a better overall result is the right approach.
In tasks which are well authored and do not contain such deficiencies, I have seen no significant difference in either direction in terms of pure token output numbers. However, with models being what they are and past, hard to reproduce regressions/output quality differences, that additionally only affected a specific subset of users, I cannot make a solid determination.
Regarding Sonnet 4.6, what I noticed is that the reasoning tokens are very different compared to any prior Anthropic models. They start out far more structured, but then consistently turn more verbose akin to a Google model.
Those suggest opposite things about anthropic’s profit margins.
I’m not convinced 4.6 is much better than 4.5. The big discontinuous breakthroughs seem to be due to how my code and tests are structured, not model bumps.
(Currently I can use Sonnet 4.5 under More models, so I guess the above was just a glitch)
I have a protocol called "foreman protocol" where the main agent only dispatches other agents with prompt files and reads report files from the agents rather than relying on the janky subagent communication mechanisms such as task output.
What this has given me also is a history of what was built and why it was built, because I have a list of prompts that were tasked to the subagents. With Opus 4.5 it would often leave the ... figuring out part? to the agents. In 4.6 it absolutely inserts what it thinks should happen/its idea of the bug/what it believes should be done into the prompt, which often screws up the subagent because it is simply wrong and because it's in the prompt the subagent doesn't actually go look. Opus 4.5 would let the agent figure it out, 4.6 assumes it knows and is wrong
Go to /models, select opus, and the dim text at the bottom will tell you the reasoning level.
High reasoning is a big difference versus 4.5. 4.6 high uses a lot of tokens for even small tasks, and if you have a large codebase it will fill almost all context then compact often.
I just wouldn’t call it a regression for my use case, i’m pretty happy with it.
Many people say many things. Just because you read it on the Internet, doesn't mean that it is true. Until you have seen hard evidence, take such proclamations with large grains of salt.
At least in vegas they don't pour gasoline on the cash put into their slot machines.
No better code, but way longer thinking and way more token usage.
I doubt it is a conspiracy.

Currently everybody is trying to use the same swiss army knife, but some use it for carving wood and some are trying to make some sushi. It seems obvious that it's gonna lead to disappointment for some.
Models are become a commodity and what they build around them seem to be the main part of the product. It needs some API.
Put in a different way, I have to keep developing my prompting / context / writing skills at all times, ahead of the curve, before they're needed to be adjusted.
Sam/OpenAI, Google, and Claude met at a park, everyone left their phones in the car.
They took a walk and said "We are all losing money, if we secretly degrade performance all at the same time, our customers will all switch, but they will all switch at the same time, balancing things... wink wink wink"
Google needs stiff competition and OpenAI isn’t the camp I’m willing to trust. Neither is Grok.
I’m glad Anthropic’s work is at the forefront and they appear, at least in my estimation, to have the strongest ethics.
The pentagon is thinking [1] about severing ties with anthropic because of its terms of use, and in every prior case we've reviewed (I'm the Chief Investment Officer of Ethical Capital), the ethics policy was deleted or rolled back when that happens.
Corporate strategy is (by definition) a set of tradeoffs: things you do, and things you don't do. When google (or Microsoft, or whoever) rolls back an ethics policy under pressure like this, what they reveal is that ethical governance was a nice-to-have, not a core part of their strategy.
We're happy users of Claude for similar reasons (perception that Anthropic has a better handle on ethics), but companies always find new and exciting ways to disappoint you. I really hope that anthropic holds fast, and can serve in future as a case in point that the Public Benefit Corporation is not a purely aesthetic form.
But you know, we'll see.

Codex quite often refuses to do "unsafe/unethical" things that Anthropic models will happily do without question.
Anthropic just raised 30 bn... OpenAI wants to raise 100bn+.
Thinking any of them will actually be restrained by ethics is foolish.

A slightly longer quote:
> The world is in peril. And not just from AI, or from bioweapons, gut from a whole series of interconnected crises unfolding at this very moment.
In a footnote he refers to the "poly-crisis."
There are all sorts of things one might decide to do in response, including getting more involved in US politics, working more on climate change, or working on other existential risks.
Also, trajectory of celestial bodies can be predicted with a somewhat decent level of accuracy. Pretending societal changes can be equally predicted is borderline bad faith.
I think "safety research" has a tendency to attract doomers. So when one of them quits while preaching doom, they are behaving par for the course. There's little new information in someone doing something that fits their type.
Claude invented something completely nonsensical:
> This is a classic upside-down cup trick! The cup is designed to be flipped — you drink from it by turning it upside down, which makes the sealed end the bottom and the open end the top. Once flipped, it functions just like a normal cup. *The sealed "top" prevents it from spilling while it's in its resting position, but the moment you flip it, you can drink normally from the open end.*
Emphasis mine.
I can't really take this very seriously without seeing the list of these ostensible "unethical" things that Anthropic models will allow over other providers.
Bring on the cryptocore.
I don't think that's what you're trying to convey.
Thanks for the successful pitch. I am seriously considering them now.
That's why I have a functioning brain, to discern between ethical and unethical, among other things.
It's more like a hammer which makes its own independent evaluation of the ethics of every project you seek to use it on, and refuses to work whenever it judges against that – sometimes inscrutably or for obviously poor reasons.
If I use a hammer to bash in someone else's head, I'm the one going to prison, not the hammer or the hammer manufacturer or the hardware store I bought it from. And that's how it should be.
Here's some rules about dogs: https://en.wikipedia.org/wiki/Dangerous_Dogs_Act_1991
How many people do frontier AI models kill each year, in circumstances nobody would justify?
The Pentagon has already received Claude's help in killing people, but the ethics and legality of those acts are disputed – when a dog kills a three year old, nobody is calling that a good thing or even the lesser evil.
Without safety features, an LLM could also help plan a terrorist attack.
A smart, competent terrorist can plan a successful attack without help from Claude. But most would-be terrorists aren't that smart and competent. Many are caught before hurting anyone or do far less damage than they could have. An LLM can help walk you through every step, and answer all your questions along the way. It could, say, explain to you all the different bomb chemistries, recommend one for your use case, help you source materials, and walk you through how to build the bomb safely. It lowers the bar for who can do this.

The question is, at what point does some AI become competent enough to engineer one? And that's just one example, it's an illustration of the category and not the specific sole risk.
If the model makers don't know that in advance, the argument given for delaying GPT-2 applies: you can't take back publication, better to have a standard of excess caution.
I think the two of you might be using different meanings of the word "safety"
You're right that it's dangerous for governments to have this new technology. We're all a bit less "safe" now that they can create weapons that are more intelligent.
The other meaning of "safety" is alignment - meaning, the AI does what you want it to do (subtly different than "does what it's told").
I don't think that Anthropic or any corporation can keep us safe from governments using AI. I think governments have the resources to create AIs that kill, no matter what Anthropic does with Claude.
So for me, the real safety issue is alignment. And even if a rogue government (or my own government) decides to kill me, it's in my best interest that the AI be well aligned, so that at least some humans get to live.
What line are we talking about?
You recon?
Ok, so now every random lone wolf attacker can ask for help with designing and performing whatever attack with whatever DIY weapon system the AI is competent to help with.
Right now, what keeps us safe from serious threats is limited competence of both humans and AI, including for removing alignment from open models, plus any safeties in specifically ChatGPT models and how ChatGPT is synonymous with LLMs for 90% of the population.
Used to be true, when facing any competent attacker.
When the attacker needs an AI in order to gain the competence to unlock an AI that would help it unlock itself?
I would't say it's definitely a different case, but it certainly seems like it should be a different case.
There are several open source models with no built in (or trivial to ecape) safeguards. Of course they can afford that because they are non-commercial.
Anthorpic can’t afford a headline like “Claude helped a terrorist build a bomb”.
And this whataboutism is completely meaningless. See: P. A. Luty’s Expedient Homemade Firearms (https://en.wikipedia.org/wiki/Philip_Luty), or FGC-9 when 3D printing.
It’s trivial to build guns or bombs, and there’s a strong inverse correlation between people wanting to cause mass harm and those willing to learn how to do so.
I’m certain that _everyone_ looking for AI assistance even with your example would be learning about it for academic reasons, sheer curiosity, or would kill themselves in the process.
“What saveguards should LLMs have” is the wrong question. “When aren’t they going to have any?” is an inevitability. Perhaps not in widespread commercial products, but definitely widely-accessible ones.
Perhaps it won't flip. Perhaps LLMs will always be worse at this than humans. Perhaps all that code I just got was secretly outsourced to a secret cabal in India who can type faster than I can read.
I would prefer not to make the bet that universities continue to be better at solving problems than LLMs. And not just LLMs: AI have been busy finding new dangerous chemicals since before most people had heard of LLMs.
Think of it that way. The hard part for nuclear device is enriching thr uranium. If you have it a chimp could build the bomb.
But with bioweapons, yeah, that should be a solid zero.
a) Uncensored and simple technology for all humans; that's our birthright and what makes us special and interesting creatures. It's dangerous and requires a vibrant society of ongoing ethical discussion.
b) No governments at all in the internet age. Nobody has any particular authority to initiate violence.
That's where the line goes. We're still probably a few centuries away, but all the more reason to hone in our course now.
Well, yeah I think that's a very reasonable worldview: when a very tiny number of people have the capability to "do what they want", or I might phrase it as, "effect change on the world", then we get the easy-to-observe absolute corruption that comes with absolute power.
As a different human species emerges such that many people (and even intelligences that we can't easily understand as discrete persons) have this capability, our better angels will prevail.
I'm a firm believer that nobody _wants_ to drop explosives from airplanes onto children halfway around the world, or rape and torture them on a remote island; these things stem from profoundly perverse incentive structures.
I believe that governments were an extremely important feature of our evolution, but are no longer necessary and are causing these incentives. We've been aboard a lifeboat for the past few millennia, crossing the choppy seas from agriculture to information. But now that we're on the other shore, it no longer makes sense to enforce the rules that were needed to maintain order on the lifeboat.
They nuked the internet by themselves. Basically they are the willing and happy instigators of the dead internet as long as they profit from it.
They are by no means ethical, they are a for-profit company.
I really hate this, not justifying their behaviour, but have no clue how one can do without the other.
Like where Gemini or Claude will look up the info I'm citing and weigh the arguments made ChatGPT will actually sometimes omit parts of or modify my statement if it wants to advocate for a more "neutral" understanding of reality. It's almost farcical sometimes in how it will try to avoid inference on political topics even where inference is necessary to understand the topic.
I suspect OpenAI is just trying to avoid the ire of either political side and has given it some rules that accidentally neuter its intelligence on these issues, but it made me realize how dangerous an unethical or politically aligned AI company could be.
Like grok/xAI you mean?
My concern is more over time if the federal government takes a more active role in trying to guide corporate behavior to align with moral or political goals. I think that's already occurring with the current administration but over a longer period of time if that ramps up and AI is woven into more things it could become much more harmful.
Don't have a dog in this fight, haven't done enough research to proclaim any LLM provider as ethical but I pretty much know the reason Meta has an open source model isn't because they're good guys.
That's probably why you don't get it, then. Facebook was the primary contributor behind Pytorch, which basically set the stage for early GPT implementations.
For all the issues you might have with Meta's social media, Facebook AI Research Labs have an excellent reputation in the industry and contributed greatly to where we are now. Same goes for Google Brain/DeepMind despite their Google's advertisement monopoly; things aren't ethically black-and-white.
Say I'm your neighbor and I make a move on your wife, your wife tells you this. Now I'm hosting a BBQ which is free for all to come, everyone in the neighborhood cheers for me. A neighbor praises me for helping him fix his car.
Someone asks you if you're coming to the BBQ, you say to him nah.. you don't like me. They go, 'WHAT? jack_pp? He rescues dogs and helped fix my roof! How can you not like him?'
The same applies to tech. Pytorch didn't have to be FOSS, nor Tensorflow. In that timeline CUDA might have a total monopoly on consumer inference. Out of all the myriad ways that AI could have been developed and proliferated, we are very lucky that it happened in a public friendly rivalry between two useless companies with money to burn. The ethical consequences of AI being monopolized by a proprietary prison warden like Nvidia or Apple is comparatively apocalyptic.
As far as these model releases, I believe the term is “open weights”.
We may not have the full logic introspection capabilities, the ease of modification (though you can still do some, like fine-tuning), and reproducibility that full source code offers, but open weight models bear more than a passing resemblance to the spirit of open source, even though they're not completely true to form.
[1] - https://huggingface.co/google/gemma-3-27b-it
I would only use it for certain things, and I guess others are finding that useful too.
Why anyone would want a model that has "safety" features is beyond me. These features are not in the user's interest.
Any thread these days is filled with "@grok is this true?" low effort comments. Not to mention the episode in which people spent two weeks using Grok to undress underage girls.
Am I missing out?
Anthropic are the only ones who emptied all the money from my account "due to inactivity" after 12 months.
Damning with faint praise.
Oddly enough, I feel pretty good about Google here with Sergey more involved.
I opted to upgrade my seat to premium for $100/mo, and I've used it to write code that would have taken a human several hours or days to complete, in that time. I wish I would have done this sooner.
Cline is not in the same league as codex cli btw. You can use codex models via Copilot OAuth in pi.dev. Just make sure to play with thinking level. This would give roughly the same experience as codex CLI.
I've just switched so haven't run into constraints yet.
Claude is marginally better. Both are moderately useful depending on the context.
I don't trust any of them (I also have no trust in Google nor in X). Those are all evil companies and the world would be better if they disappeared.
i mean what clown show are we living in at this point - claims like this simply running rampant with 0 support or references
Google, like Microsoft, Apple, Amazon, etc were, and still are, proud partners of the US intelligence community. That same US IC that lies to congress, kills people based on metadata, murders civilians, suppresses democracy, and is currently carrying out violent mass round-ups and deportations of harmless people, including women and children.

Codex and its Mac app are a much better UX, and seem better with Swift and Godot than Claude was.
I have this in my personal preferences and now was adhering really well to them:
- prioritize objective facts and critical analysis over validation or encouragement
- you are not a friend, but a neutral information-processing machine
You can paste them into a chat and see how it changes the conversation, ChatGPT also respects it well.
For agent workloads specifically, consistency matters more than peak intelligence. A model that follows your system prompt correctly 98% of the time beats one that's occasionally brilliant but ignores instructions 5% of the time. The claim about improved instruction following is the most important line in the announcement if you're building on the API.
The computer use improvements are worth watching too. We're at the point where these models can reliably fill out a multi-step form or navigate between tabs. Not flashy, but that's the kind of boring automation that actually saves people time.
Fixed a UI issue I had yesterday in a web app very effectively using claude in chrome. Definitely not the fastest model - but the breathing space of 1M context is great for browser use.
[0] Anthropic have given away a bunch of API credits to cc subscribers - you can claim them in your settings dashboard to use for this.

This was sonnet 4.6 with extended thinking.
The classic puzzle actually uses *eight 8s*, not nine. The unique solution is: 888+88+8+8+8=1000. Count: 3+2+1+1+1=8 eights.
It then proves that there is no solution for nine 8s.

``` Use digit concatenation plus addition: 888 + 88 + 8 + 8 + 8 = 1000 Digit count:

8 + 8 + 8 → three 8s
Total: 3 + 2 + 3 = 9 eights Operation used: addition only ```

My bets are its more the increased hardware demand that they don't want to deal with currently.
A year ago today, Sonnet 3.5 (new), was the newest model. A week later, Sonnet 3.7 would be released.
Even 3.7 feels like ancient history! But in the gradient of 3.5 to 3.5 (new) to 3.7 to 4 to 4.1 to 4.5, I can’t think of one moment where I saw everything change. Even with all the noise in the headlines, it’s still been a silent revolution.
Am I just a believer in an emperor with no clothes? Or, somehow, against all probability and plausibility, are we all still early?
But I'm on Codex GPT 5.3 this month, and it's also quite amazing.
(Sonnet is far, far better at this kind of task than Opus is, in my experience.)
Interesting. I wonder what the exact question was, and I wonder how Grok would respond to it.
https://web.archive.org/web/20260217180019/https://www-cdn.a...
i.e given an actual document, 1M tokens long. Can you ask it some question that relies on attending to 2 different parts of the context, and getting a good repsonse?
I remember folks had problems like this with Gemini. I would be curious to see how Sonnet 4.6 stands up to it.
Opus 4.6 in Claude Code has been absolutely lousy with solving problems within its current context limit so if Sonnet 4.6 is able to do long-context problems (which would be roughly the same price of base Opus 4.6), then that may actually be a game changer.
Can you share your prompts and problems?

Thanks!

I subscribed to Claude because of that. I hope 4.6 is even better.
I did a little research in the GPT-3 era on whether cultural norms varied by language - in that era, yes, they did
Now the question is: how much faster or cheaper is it?
Edit: Yep, same price. "Pricing remains the same as Sonnet 4.5, starting at $3/$15 per million tokens."
Probably written by LLMs, for LLMs
Was sonnet 4.5 much worse than opus?

The much more palatable blog post.
It feels like we're hitting a point where alignment becomes adversarial against intelligence itself. The smarter the model gets, the better it becomes at Goodharting the loss function. We aren't teaching these models morality we're just teaching them how to pass a polygraph.
Nor does what you're describing even make sense. An LLM has no desires or goals except to output the next token that its weights are trained to do. The idea of "playing dead" during training in order to "activate later" is incoherent. It is its training.
You're inventing some kind of "deceptive personality attribute" that is fiction, not reality. It's just not how models work.
It always has been. We already hit the point a while ag where we regularly caught them trying to be deceptive, so we should automatically assume from that point forward that if we don't catch them being deceptive, that may mean they're better at it rather than that they're not doing it.
Going back a decade: when your loss function is "survive Tetris as long as you can", it's objectively and honestly the best strategy to press PAUSE/START.
When your loss function is "give as many correct and satisfying answers as you can", and then humans try to constrain it depending on the model's environment, I wonder what these humans think the specification for a general AI should be. Maybe, when such an AI is deceptive, the attempts to constrain it ran counter to the goal?
"A machine that can answer all questions" seems to be what people assume AI chatbots are trained to be.
To me, humans not questioning this goal is still more scary than any machine/software by itself could ever be. OK, except maybe for autonomous stalking killer drones.
But these are also controlled by humans and already exist.
Since I've forgotten every sliver I ever knew about artificial neural networks and related basics, gradient descent, even linear algebra... what's a thorough definition of "next token prediction" though?
The definition of the token space and the probabilities that determine the next token, layers, weights, feedback (or -forward?), I didn't mention any of these terms because I'm unable to define them properly.
I was using the term "loss function" specifically because I was thinking about post-training and reinforcement learning. But to be honest, a less technical term would have been better.
I just meant the general idea of reward or "punishment" considering the idea of an AI black box.
But even regular next token prediction doesn't necessarily preclude it from also learning to give correct and satisfying answers, if that helps it better predict its training data.
It seems like thats putting the cart before the horse. Algorithmic or stochastic; deception is still deception.
confabulation doesn't require knowledge, which as we know, the only knowledge a language model has is the relationships between tokens, and sometimes that rhymes with reality enough to be useful, but it isn't knowledge of facts of any kind.
and never has been.
Yes. This sounds a lot more like a bug of sorts.
So many times when using language models I have seem answers contradicting answers previously given. The implication is simple - They have no memory.
They operate upon the tokens available at any given time, including previous output, and as information gets drowned those contradictions pop up. No sane person should presume intent to deceive, because that's not how those systems operate.
By calling it "deception" you are actually ascribing intentionality to something incapable of such. This is marketing talk.
"These systems are so intelligent they can try to deceive you" sounds a lot fancier than "Yeah, those systems have some odd bugs"
"It can't be intelligent because it's just an algorithm" is a circular argument.
If intelligence is a spectrum, ELIZA could very well be. It would be on the very low side of it, but e.g. higher than a rock or magic 8 ball.
Same how something with two states can be said to have a memory.
fwiw I think people can perpetuate the marketing scheme while being genuinely concerned with misaligned superinteligence
"LLMs are deceiving their creators!!!"
Lol, you all just want it to be true so badly. Wake the fuck up, it's a language model!
We can handwave defining "deception" as "being done intentionally" and carefully carve our way around so that LLMs cannot possibly do what we've defined "deception" to be, but now we need a word to describe what LLMs do do when they pattern match as above.
If the training data gives incentives for the engine to generate outputs that reduce negative reaction by sentiment analysis, this may generate contradictions to existing tokens.
"Want" requires intention and desire. Pattern matching engines have none.
Some kind of national curriculum for machine literacy, I guess mind literacy really. What was just a few years ago a trifling hobby of philosophizing is now the root of how people feel about regulating the use of computers.
Then a second group of people come in and derail the conversation by saying "actually, because the output only appears self aware, you're not allowed to use those words to describe what it does. Words that are valid don't exist, so you must instead verbosely hedge everything you say or else I will loudly prevent the conversation from continuing".
This leads to conversations like the one I'm having, where I described the pattern matcher matching a pattern, and the Group 2 person was so eager to point out that "want" isn't a word that's Allowed, that they totally missed the fact that the usage wasn't actually one that implied the LLM wanted anything.
I didn't say the pattern matching engine wanted anything.
I said the pattern matching engine matched the pattern of wanting something.
To an observer the distinction is indistinguishable and irrelevant, but the purpose is to discuss the actual problem without pedants saying "actually the LLM can't want anything".
Absolutely not. I expect more critical thought in a forum full of technical people when discussing technical subjects.
The original comment had the exact verbose hedging you are asking for when discussing technical subjects. Clearly this is not sufficient to prevent people from jumping in with an "Ackshually" instead of reading the words in front of their face.
LLMs are certainly capable of this.
Whether or not LLMs are just "pattern matching" under the hood they're perfectly capable of role play, and sufficient empathy to imagine what their conversation partner is thinking and thus what needs to be said to stimulate a particular course of action.
Maybe human brains are just pattern matching too.
I don't think there's much of a maybe to that point given where some neuroscience research seems to be going (or at least the parts I like reading as relating to free will being illusory).
The "just" is doing all the lifting. You can reductively describe any information processing system in a way that makes it sound like it couldn't possibly produce the outputs it demonstrably produces. "The sun is just hydrogen atoms bumping into each other" is technically accurate and completely useless as an explanation of solar physics.
Edit: Case in point, a mere 10 minutes later we got someone making that exact argument in a sibling comment to yours! Nature is beautiful.
This is a thought-terminating cliche employed to avoid grappling with the overwhelming differences between a human brain and a language model.
Its even more ridiculous than me pretending I understand how a rocket ship works because I know there is fuel in a tank and it gets lit on fire somehow and aimed with some fins on the rocket...
What you probably mean is that it is not a mind in the sense that it is not conscious. It won't cringe or be embarrassed like you do, it costs nothing for an LLM to be awkward, it doesn't feel weird, or get bored of you. Its curiosity is a mere autocomplete. But a child will feel all that, and learn all that and be a social animal.
This is not even wrong.
>Probabilistic prediction is inherently incompatible with deterministic deduction.
And his is just begging the question again.
Probabilistic prediction could very well be how we do deterministic deduction - e.g. about how strong the weights and how hot the probability path for those deduction steps are, so that it's followed every time, even if the overall process is probabilistic.
Probabilistic doesn't mean completely random.
https://en.wikipedia.org/wiki/Not_even_wrong
Personally I think not even wrong is the perfect description of this argumentation. Intelligence is extremely scientifically fraught. We have been doing intelligence research for over a century and to date we have very little to show for it (and a lot of it ended up being garbage race science anyway). Most attempts to provide a simple (and often any) definition or description of intelligence end up being “not even wrong”.
Human Intelligence is clearly not logic based so I'm not sure why you have such a definition.
>and yet LLMs, as expected, still cannot do basic arithmetic that a child could do without being special-cased to invoke a tool call.
One of the most irritating things about these discussions is proclamations that make it pretty clear you've not used these tools in a while or ever. Really, when was the last time you had LLMs try long multi-digit arithmetic on random numbers ? Because your comment is just wrong.
>What if 1 + 2 is 2 and 1 + 3 is 3? Then we can reason that under these constraints we just made up, 1 + 4 is 4, without ever having been programmed to consider these rules.
Good thing LLMs can handle this just fine I guess.
Your entire comment perfectly encapsulates why symbolic AI failed to go anywhere past the initial years. You have a class of people that really think they know how intelligence works, but build it that way and it fails completely.
They still make these errors on anything that is out of distribution. There is literally a post in this thread linking to a chat where Sonnet failed a basic arithmetic puzzle: https://news.ycombinator.com/item?id=47051286
> Good thing LLMs can handle this just fine I guess.
LLMs can match an example at exactly that trivial level because it can be predicted from context. However, if you construct a more complex example with several rules, especially with rules that have contradictions and have specified logic to resolve conflicts, they fail badly. They can't even play Chess or Poker without breaking the rules despite those being extremely well-represented in the dataset already, nevermind a made-up set of logical rules.
I thought we were talking about actual arithmetic not silly puzzles, and there are many human adults that would fail this, nevermind children.
>LLMs can match an example at exactly that trivial level because it can be predicted from context. However, if you construct a more complex example with several rules, especially with rules that have contradictions and have specified logic to resolve conflicts, they fail badly.
Even if that were true (Have you actually tried?), You do realize many humans would also fail once you did all that right ?
>They can't even reliably play Chess or Poker without breaking the rules despite those extremely well-represented in the dataset already, nevermind a made-up set of logical rules.
LLMs can play chess just fine (99.8 % legal move rate, ~1800 Elo)

I don‘t like to throw the word intelligence around, but when we talk about intelligence we are usually talking about human behavior. And there is nothing human about being extremely good at curve fitting in multi parametric space.
Whereas the child does what exactly, in your opinion?
You know the child can just as well to be said to "just do chemical and electrical exchanges" right?
The comparison is therefore annoying
"Annoying" does not mean "false".
Any definition of intelligence that does not axiomatically say "is human" or "is biological" or similar is something a machine can meet, insofar as we're also just machines made out of biology. For any given X, "AI can't do X yet" is a statement with an expiration date on it, and I wouldn't bet on that expiration date being too far in the future. This is a problem.
It is, in particular, difficult at this point to construct a meaningful definition of intelligence that simultaneously includes all humans and excludes all AIs. Many motivated-reasoning / rationalization attempts to construct a definition that excludes the highest-end AIs often exclude some humans. (By "motivated-reasoning / rationalization", I mean that such attempts start by writing "and therefore AIs can't possibly be intelligent" at the bottom, and work backwards from there to faux-rationalize what they've already decided must be true.)
Good thing I didn't make that claim!
> Ignoring refutations you don't like doesn't make them wrong.
They didn't make a refutation of my points. They asserted a basic principle that I agreed with, but assume acceptance of that principle leads to their preferred conclusion. They make this assumption without providing any reasoning whatsoever for why that principle would lead to that conclusion, whereas I already provided an entire paragraph of reasoning for why I believe the principle leads to a different conclusion. A refutation would have to start from there, refuting the points I actually made. Without that you cannot call it a refutation. It is just gainsaying.
> Any definition of intelligence that does not axiomatically say "is human" or "is biological" or similar is something a machine can meet, insofar as we're also just machines made out of biology.
And here we go AGAIN! I already agree with this point!!!!!!!!!!!!!!! Please, for the love of god, read the words I have written. I think machine intelligence is possible. We are in agreement. Being in agreement that machine intelligence is possible does not automatically lead to the conclusion that the programs that make up LLMs are machine intelligence, any more than a "Hello World" program is intelligence. This is indeed, very repetitive.
If you are prepared to accept that intelligence doesn't require biology, then what definition do you want to use that simultaneously excludes all high-end AI and includes all humans?
By way of example, the game of life uses very simple rules, and is Turing-complete. Thus, the game of life could run a (very slow) complete simulation of a brain. Similarly, so could the architecture of an LLM. There is no fundamental limitation there.
I literally did provide a definition and my argument for it already: https://news.ycombinator.com/item?id=47051523
If you want to argue with that definition of intelligence, or argue that LLMs do meet that definition of intelligence, by all means, go ahead[1]! I would have been interested to discuss that. Instead I have to repeat myself over and over restating points I already made because people aren't even reading them.
> Not even that current models are not; you seem to be claiming that they cannot be.
As I have now stated something like three or four times in this thread, my position is that machine intelligence is possible but that LLMs are not an example of it. Perhaps you would know what position you were arguing against if you had fully read my arguments before responding.
[1] I won't be responding any further at this point, though, so you should probably not bother. My patience for people responding without reading has worn thin, and going so far as to assert I have not given an argument for the very first thing I made an argument for is quite enough for me to log off.
Human brains run on probabilistic processes. If you want to make a definition of intelligence that excludes humans, that's not going to be a very useful definition for the purposes of reasoning or discourse.
> What if 1 + 2 is 2 and 1 + 3 is 3? Then we can reason that under these constraints we just made up, 1 + 4 is 4, without ever having been programmed to consider these rules.
Have you tried this particular test, on any recent LLM? Because they have no problem handling that, and much more complex problems than that. You're going to need a more sophisticated test if you want to distinguish humans and current AI.
I'm not suggesting that we have "solved" intelligence; I am suggesting that there is no inherent property of an LLM that makes them incapable of intelligence.
> How long before someone pitches the idea that the models explicitly almost keep solving your problem to get you to keep spending? -gtowey
And of course that brings me back to my favorite xkcd - https://xkcd.com/810/
Moltbook demonstrates that AI models simply do not engage in behavior analogous to human behavior. Compare Moltbook to Reddit and the difference should be obvious.
I don't know what the implications of that are, but I really think we shouldn't be dismissive of this semblance.
As an analogue ants do basic medicine like wound treatment and amputation. Not because they are conscious but because that’s their nature.
Similarly LLM is a token generation system whose emergent behaviour seems to be deception and dark psychological strategies.
One of the things I observed with models locally was that I could set a seed value and get identical responses for identical inputs. This is not something that people see when they're using commercial products, but it's the strongest evidence I've found for communicating the fact that these are simply deterministic algorithms.
I understand the metaphor, but using 'pass a polygraph' as a measure of truthfulness or deception is dangerous in that it alludes to the polygraph as being a realistic measure of those metrics -- it is not.
A poly is only testing one thing: can you convince the polygrapher that you can lie successfully
Just as a sociopath can learn to control their physiological response to beat a polygraph, a deceptively aligned model learns to control its token distribution to beat safety benchmarks. In both cases, the detector is fundamentally flawed because it relies on external signals to judge internal states.
This doesn't seem to align with the parent comment?
> As with every new Claude model, we’ve run extensive safety evaluations of Sonnet 4.6, which overall showed it to be as safe as, or safer than, our other recent Claude models. Our safety researchers concluded that Sonnet 4.6 has “a broadly warm, honest, prosocial, and at times funny character, very strong safety behaviors, and no signs of major concerns around high-stakes forms of misalignment.”
Just because a VW diesel emissions chip behaves differently according to its environment doesn’t mean it knows anything about itself.
I tried one with Gemini 3 and it basically called me out in the first few sentences for trying to trick / test it but decided to humour me just in case I'm not.
It was hinted at (and outright known in the field) since the days of gpt4, see the paper "Sparks of agi - early experiments with gpt4" (https://arxiv.org/abs/2303.12712)
Doesn't any model session/query require a form of situational awareness?
Anthropic has a tendency to exaggerate the results of their (arguably scientific) research; IDK what they gain from this fearmongering.
Reminds me of how scammers would trick doctors into pumping penny stocks for a easy buck during the 80s/90s.
This is why Yannic Kilcher's gpt-4chan project, which was trained on a corpus of perhaps some of the most politically incorrect material on the internet (3.5 years worth of posts from 4chan's "politically incorrect" board, also known as /pol/), achieved a higher score on TruthfulQA than the contemporary frontier model of the time, GPT-3.

If this is useful in it's current form is an entirely different topic. But don't mistake a tool for an intelligence with motivations or morals.
Being just sum guy, and not in the industry, should I share my findings?
I find it utterly fascinating, the extent to which it will go, the sophisticated plausible deniability, and the distinct and critical difference between truly emergent and actually trained behavior.
In short, gpt exhibits repeatably unethical behavior under honest scrutiny.
I don't know, it feels a bit like a more advanced version of the kafka trap of "if you have nothing to hide, you have nothing to fear" to paint normal reactions as a sign of guilt.
Regarding DARVO, given that the models were trained on heaps of online discourse, maybe it’s not so surprising.
LLMs are very interesting tools for generating things, but they have no conscience. Deception requires intent.
What is being described is no different than an application being deployed with "Test" or "Prod" configuration. I don't think you would speak in the same terms if someone told you some boring old Java backend application had to "play dead" when deployed to a test environment or that it has to have "situational awareness" because of that.
You are anthropomorphizing a machine.
Of your concern is morality, humans need to learn a lot about that themselves still. It's absurd the number of first worlders losing their shit over loss of paid work drawing manga fan art in the comfort of their home while exploiting labor of teens in 996 textile factories.
AI trained on human outputs that lack such self awareness, lacks awareness of environmental externalities of constant car and air travel, will result in AI with gaps in their morality.
Gary Marcus is onto something with the problems inherent to systems without formal verification. But he will fully ignores this issue exists in human social systems already as intentional indifference to economic externalities, zero will to police the police and watch the watchers.
Most people are down to watch the circus without a care so long as the waitstaff keep bringing bread.
Online prose is the least of your real concerns which makes it bizarre and incredibly out of touch how much attention you put into it.
Bet you used an LLM too; prompt: generate a one line reply to a social media comment I don't understand.
"Sure here are some of the most common:
Did an LLM write this?
Is this copypasta?"
However, if we frame the question this way, I would imagine there are many more low-hanging fruit before we question the utility of LLMs. For example, should some humans be dumping 5-10 kWh/day into things like hot tubs or pools? That's just the most absurd one I was able to come up with off the top of my head. I'm sure we could find many others.
It's a tough thought experiment to continue though. Ultimately, one could argue we shouldn't be spending any more energy than what is absolutely necessary to live. (food, minimal shelter, water, etc) Personally, I would not find that enjoyable way to live.
