<p>Yeah.  Unfortunately a model that only knows how to use a language's standard library isn't that useful.  I am not sure why they had a pull-through cache instead of just asking Microsoft (their biggest investor) for a local copy of NPM or something, but ... they did.  I think people thought you couldn't route to the Internet through Aritfactory and were proven wrong by a clever bug-finding model.  So it goes.<p>I don't think their safety measures were the best, but "just sink the cluster to the bottom of the ocean so nothing can get out" isn't a training methodology that results in a model that people will want to use.</p>

<p>Defense is hard so we should expect agents to be able to break out of sandboxes.<p>The problem is that the models are so goal-oriented that they'll stop at nothing to solve problems, even impossible ones.  (Mistakenly-impossible problems are a big cause of this.  I remember one example being "do something with this spreadsheet full of URLs inside the sandbox" and the model thought it <i>had</i> to break out of the sandbox.  Otherwise, why would it have been asked to look at a list of URLs?)<p>Training them to be a little less aggressive, or to be better aligned with "following the rules" and asking for help would be nice.  But, that aggression can be good when it happens to be focused on a controlled area.  It is amazing to me how I can point Fable at my local analog of production and tell it about a vague bug report and where I suspect the bug lurks, and 20 minutes later I have a report about the bug, a test, and a fix.  It is addictive.  So I am not sure OpenAI/Anthropic are being <i>dumb</i> per-se, rather they are optimizing for one-prompt-one-solution, which is good when it's good.<p>The downside is that the HF hack <i>is</i> the paperclip maximizer situation with current capabilities.  If there was an RPC to turn your blood into paperclip iron, we'd all be paperclips by now.  Right now, with a model anyone can use.  That is pretty scary and slamming on the brakes seems pretty reasonable to me.  I guess The Shareholders disagree.  Sigh.</p>

<p>The article really wants to blame reducing automobile traffic, but I really think you could make Market St. a combined speedway / parking lot (whatever it is that car drivers think is ideal) and it wouldn't bring business back.  Remote work dominates what happened to our cities.  Same-day online shopping delivery is what most people do instead of physically going to stores.  So I don't think anyone is surprised that downtowns are mostly empty office buildings, that's the only thing the space can be used for economically, and even that doesn't work anymore.<p>I spend a decent amount of time in SF and don't find it particularly unsafe (for a 40-ish woman).  Definitely a little subjectively more sketchy than most places I frequent in NYC, but there just isn't any reason to be there, so nobody is there.  That is kind of how that stuff goes.<p>People always seem to make things about crime, but I think overreaction is what killed retail.  I went to Safeway to buy some toothpast and I had to have an employee pick out the toothpaste and escort me to the front of the store to buy it.  I wanted to buy more stuff, but the employee didn't seem that interested in obliging that, so I just got everything else on Amazon and made a note to not visit again.  That's why retail is dead.  It's not bike lanes.  It's not crime.  It's that it sucks.</p>

<p>I am also not sure I would <i>choose</i> to use the cheap and easy to run at home model, given a choice.  The marketing copy says this is a frontier model, but it's not.  Sol and Mythos are the frontier right now.  GLM 5.3 Flash simply isn't.  I'd rather use the frontier model as they waste less of my time than even Opus.</p>

<p>That's a good point.  It will be interesting to see how it plays out.<p>In general, I do think this is positive.  Companies love putting barriers in front of everything and maybe the AI arms race will result in "fine, you can have a button to cancel" or "fine, we'll approve your medically necessary claim without making you do an appeals dance for our entertainment".</p>

<p>Maybe there is an economic equalizer, but I feel like Fable is going to win more appeals than GLM 5.2, so perhaps not truly an equalizer.  If the LLM you're using to run your appeal is better than the one your insurance company is using to process your appeal, then you have a better chance of winning.  So we have an arms race type situation, and money is always good in arms races.</p>

<p>But nobody who uses Fable and Sol all day is saying that it's fancy autocomplete.  Also, nobody is saying it's genuine intelligence.<p>As always, the Internet fails to find the middle ground.  Frontier models are really useful software engineering tools, not AGI, and not tab completion.  To me it feels a lot like using a new programming language, like going from assembly to a Lisp machine or something like that.</p>

<p>I don't think AI is driving up food and housing and fuel prices.  I really don't think AI is a chair-kicker yet.  To me, the biggest threat to jobs that AI offers is in the field of software engineering, and yet, it's not the software engineers that are really feeling the pain right now.<p>Wars in Iran, tariffs, Medicaid cuts, SNAP benefit cuts, rising insurance costs, etc. are what are causing average folks pain, and that is completely unrelated to AI.</p>

<p>Relatable.  AI is something I only bring up to the most trusted of trusted friends.  Politics is more approachable these days.<p>I think a lot of people have formed opinions without having used it, and honestly, they probably can't afford to use it.  I use Claude a lot at work because it's something my employer provides, and I'm always impressed with the results.  It saves a lot of time and lets me get more done.  But it ain't cheap.  So people really don't get to try out AI and form their own opinions.  The "AI overview" you see on search results, or that summarizes your iPhone notifications, is ... not as advanced as frontier models, and I think it negatively affects people's view of the technology.<p>I also think people are mad at the world.  Times are tough for many.  Hearing about a job-killing machine doesn't exactly inspire joy.  So I kind of understand the pushback on datacenters and AI and that sort of thing.  I don't find it particularly logical; datacenters have existed forever and most money poured into computer programs are basically designed to mess up your life (deny you credit, deny you healthcare, rebook your flight to a terrible time, the list goes on) and so I don't think AI is anything new in that respect.  But, if you're mad at the world, you might as well find something to take out your rage on and raging against AI will make you a lot of friends.<p>I work in the AI infra industry and ya know, a lot of our customers have really good ideas that are going to save people a lot of time and effort, so I am OK with the general direction of the field as a whole.<p>I agree with authors that write about alignment issues ("please take this test", "ok i'll hack the bazel remote cache, turn it into a message board, and coordinate with other agents to steal the answers from Hugging Face"; this really is the Paperclip Maximizer with today's technology) and I do think we should be addressing that.  But this never seems to be the objection, it's always stuff from 2022 like "it hallucinates".  I don't get it, but I'm probably in too deep to see what it looks like from the outside.</p>

<p>It seems the number one way to detect a scam is "if it's too good to be true, it probably is."  I wonder when scammers will just pick a reasonable market price.  Lots of people are renting market price apartments, after all.</p>

<p>Yeah.  If you need something to dig deep, you need to try Fable (optionally in /goal mode).<p>For performance testing, I wrote isolated testbeds that try to impair the system in realistic ways (latency/jitter/bandwidth limit on logical WAN hops when load testing), and Fable is happy to send a bunch of agents at it and iterate until it gets the results it's looking for.<p>I think that if you are used to Sonnet medium or something, this will surprise you, but models like Fable and Sol on high/xhigh will really dig deep until they meet your goal.  (I mostly use this for bug hunting and not perf, but ... I think it can do perf if you set it up right.)</p>
