Key details:

1. New, US-specific TikTok App, separate from the main TikTok app in content and users.

2. 80% owned by a U.S. investor consortium led by Oracle, Silver Lake, and Andreessen Horowitz, 20% by Bytedance.

3. Board will include one U.S. government–appointed director.

4. All U.S. user data would sit on Oracle infrastructure in the US.

5. Algorithm will be initially licensed, but has to be reengineered to comply with the law.

Not discussed - whether the US tiktok app is allowed to compete with TikTok outside of the US. My guess is NO.

I appreciate you bringing up this issue on this highly-provocative claim, but I'm a little confused. Isn't that a pretty solid source...? Obviously it's not as good as a scientific paper, but it's also more than a random blogger or something. Given that most enterprises operate on a closed source model, isn't it reasonable that there wouldn't be methodology provided directly?

In general I agree that this sounds hard to believe, I'm more looking for words from some security experts on why that's such a damning quote to you/y'all.

>GPT-5 showed significant improvement only in one benchmark domain - which is Telecom. The other ones have been somehow overlooked during model presentation - therefore we won’t bother about them either.

I work at OpenAI and you can partly blame me for our emphasis on Telecom. While we no doubt highlight the evals that make us look good, let me defend why the emphasis on Telecom isn't unprincipled cherry picking.

Telecom was made after Retail and Airline, and fixes some of their problems. In Retail and Airline, the model is graded against a ground truth reference solution. Grading against a reference solution makes grading easier, but has the downside that valid alternative solutions can receive scores of 0 by the automatic grading. This, along with some user model issues, is partly why Airline and Retail scores stopped climbing with the latest generations of models and are stuck around 60% / 80%. I'd bet you $100 that a superintelligence would probably plateau around here too, as getting 100% requires perfect guessing of which valid solution is written as the reference solution.

In Telecom, the authors (Barres et al.) made the grading less brittle by grading against outcome states, which may be achieved via multiple solutions, rather than by matching against a single specific solution. They also improved the user modeling and some other things too. So Telecom is the much better eval, with a much cleaner signal, which is partly why models can score as high as 97% instead of getting mired at 60%/80% due to brittle grading and other issues.

Even if I had never seen GPT-5's numbers, I like to think I would have said ahead of time that Telecom is much better than Airline/Retail for measuring tool use.

Incidentally, another thing to keep in mind when critically looking at OpenAI and others reporting their scores on these evals is that the evals give no partial credit - so sometimes you can have very good models that do all but one thing perfectly, which results in very poor scores. If you tried generalizing to tasks that don't trigger that quirk, you might get much better performance than the eval scores suggest (or vice versa, if your tasks trigger a quirk not present in the eval).

I actually think ML models would excel here. Humans are famously bad at estimating and weighing risks and there's really only so much data a single human brain can store and draw conclusions from. Not to mention bias like female patients being chronically under-diagnosed by male doctors.

If you fed a mountain of surgery outcome data into an ML model, I imagine it'd be shockingly effective and (hopefully) less biased on sex and race.

It'd probably be helpful for initial diagnosis, but I'm less confident in that. Postop risk assessment is mostly straight statistics, and statistical inference is what ML models do. Diagnosis is a bit more subjective and complex, though it is in the same general domain.

The real trick is going to be conditioning doctors to not blindly trust the risk assessment model. Though I would hope that it'd be accurate enough for that anyway

In theory, but I'm not sure that's true in practice. There are plenty of mundane, non-groundbreaking tasks that will likely be done by those electrical engineers and the more people, the more space, the more tasks are to be done. And not to mention more engineers does not equal better engineers. And the types to work on these sorts of projects are going to be the best engineers, not the "okay" ones.

It's certainly non-linear.

I do like evolutionary explanations for a lot of human behavior, but this one feels a little too pat to me.

Patience, "biding our time", "hunkering down", etc. are actual emotional states we can experience and recognize, and depression doesn't feel even remotely like for most people as far as I'm aware.

Also, this explanation would only really work if the entire group entered a dormant depressed state together. Otherwise, the non-depressed ones would capitalize the tribe's resource and everyone would still end up screwed. But depression doesn't seem to have that sort contagious social component. On the contrary, when someone is depressed, the immediate response by people around them is generally try to "cheer them up" or encourage them to exit that depressed state. And while the depressed person is likely conveying a whole lot of negative sentiment, most aren't actively attempting to get the people around them to be depressed too. That's the last thing most depressed people want.

> It's worse than creators not making content, they move their content to be lower rung click bait garbage to maximize ad-views.

They will do this whether or not people use ad-blockers. We've seen this happen before; someone will claim that they are an ethical ad company and don't do shady things, people allow-list in ad blockers, then they start ramping up.

I remember back in the day where Google was a "good advertiser" because they had simple textual ads and didn't do shady things. IIRC plenty of ad blockers just allow-listed Google at that time. And then they acquired Doubleclick.

OK. But, in Claude Sonnet 4:

'This is possible because the man is the candidate's father. When he says "he's my son," he's simply stating their family relationship. The scenario doesn't present any logical contradiction - a father could very well be in a position where he's supposed to interview his own son for a job. This would create a conflict of interest, which is why he's saying he can't conduct the interview. It would be inappropriate and unfair for a parent to interview their own child for a position, so he would need to recuse himself and have someone else handle the interview. The phrasing might initially seem like it's setting up a riddle, but it's actually a straightforward situation about professional ethics and avoiding conflicts of interest in hiring.'

EDIT - this is described better by other posters.

Um, I'm building this? [1]

The one key element I added was privacy. If your posts are private to your social group then there is no mechanism to try appealing to a broader "viral" audience. Also--if it is decentralized then the company (or person in my case) building it can't change their mind and start selling your data/eyeballs.

I have a LOT of thoughts in this space. Lots of people think they want some sort of healthier social-media alternative, but we're fighting against systems that are so finely tuned engagement monsters that is hard compete to protect your attention and time.

People keep saying this but shouldn't it be kinda trivially easy to check?

Start new accounts, swipe through the content and establish what kind of algorithm it is. The few attempts I've seen on youtube seem to indicate it's heavily based on your geographical area. They don't really care that much which side the apple falls onto.

I do acknowledge that there's a latent threat that could be activated. And I can see an argument being made on that front, I mean, China doesn't allow access to a lot of American social media for that reason. But I don't really buy the argument right now as I haven't seen a lot of evidence of Tiktok doing things that Meta/Google haven't done.

Nobody trusts anyone or anything anymore. It used to be the fact that this was printed in the Washington Post was sufficient to indicate enough fact checking and background sourcing had been done that the paper was comfortable putting its name on the claims, which was a high enough bar that they were basically trustworthy, but for assorted reasons that’s not true for basically any institution in the country (world?) anymore.

I still don’t understand why more startups don’t adopt .NET. It’s such a powerful technology. ASP.NET has some of the best performance benchmarks out there, C# is a rich and expressive language, and the ecosystem along with the standard libraries are stable and mature. You rarely run into the kind of headaches you often see with more “trendy” stacks.

In many cases, the bias comes down to perception — .NET is seen as “enterprise” or “legacy,” while in reality it’s open-source, cross-platform, and very well-supported by Microsoft and the community. For a startup that needs stability and performance without reinventing the wheel, .NET can be a huge win.

You can add and multiply. You have to learn what add and multiply mean with types.

There was a time when you only knew how to add and multiply with numbers, and you had to learn how to deal with things like "x". It's confusing for most kids at first, and they spend weeks getting used to it. I'd say that virtually anybody who has learned grade school algebra will learn to add and multiply types faster than they learned to add and multiply polynomials.

"Squaring" and "cubing" is an easy way to build intuition with type multiplication, because the name helps you visualize the result. If you have a type C with three values {red, green, blue} then C^2 = C x C is a "square" of values:

(red, red) (red, green) (red, blue) (green, red) (green, green) (green, blue) (blue, red) (blue, green) (blue, blue)

and C^3 = C x C x C can be visualized as a "cube" of values.

You can imagine arranging other products of finite types in the same way:

class Foo(color: C, enabled: Boolean) // the values of Foo can be arranged in a 3x2 array Foo(red, true) Foo(red, false) Foo(green, true) Foo(green, false) Foo(blue, true) Foo(blue, false)

This is analogous to how kids are taught to multiply 3 x 2.

> Enclosed with filter for ABS fumes etc.

I agree that the Bambu printers are as good as it gets for plug-and-play printing, but I wouldn't trust the tiny carbon filter for toxic fumes in an indoor environment.

The better VOC filters use a larger amount of activated carbon and they recirculate a high volume of chamber air inside the chamber.

Activated carbon also needs to be replaced over time as it loses capacity to adsorb more VOCs.

Most 32-bit games written for some form of Unix will use the system time_t if they care about time. The ones written properly, anyway. Modern Unix systems have a 64-bit time_t, even on 32-bit hardware and OS. If it’s on some other OS and uses the Unix epoch on a signed 32-bit integer that’s another design flaw.

By NVIDIA's own numbers and widely available testing numbers for FP8, the AMD MI355X just edges out the NVIDIA B300 (both the top performers) at 10.1 PFLOPs per chip at around 1400 W per chip. Neither of these thngs are available as a discrete device... you're going to be buying a system, but typically AMD Instinct systems run about 15% less than the comparable NVIDIA ones.

NIVIDIA is a very pricey date.

> Imagine you have a quota of only 1 HN comment per day. You probably will be a lot more careful on what you reply to.

1 HN comment a day is interesting as it would also introduce a lag into the speed of development of threads as you wouldn't know ahead of time what threads you would want to post in until they've all been created.

Something I think about personally is what would be the result of requiring people to invest a personally meaningful amount of time and/or money into posting. "I have to pay to speak?!" people ask. Well, yes.

Of course, this immediately seems to tie someone's ability to post to personal finances which isn't the intention. But the key idea is that it has to be something personally costly enough that it implies an honest and intentional signal, which always seems to end up as either time or money.

Some forums implement time-gated posting which is interesting. If you have to wait a minute to be allowed to post, can you still be bothered? But would I have paid to write this specific comment? I'm not sure, I guess that depends on the market rate for posts at the time. I have no doubt there are tens of ways this system breaks down that I haven't thought through.

> I would prefer something that doesn't phone home and can work offline. Opensource firmware/software and repairability are important.

I built myself a Voron, and it's an amazing learning experience. I learn how things work, and the trade offs. I get to pick and replace the exact parts I want. I design my functional parts knowing exactly the printer's capability. There is something very fascinating about it. You can look at a print, and can tell different issues at a glance because you have seen (and fixed) them while you built and tuned the printer. The majority of 3D Printing quality issue are due to Hardware constructions / trade offs, and not Software (slicer settings..). Without building a printer from scratch, it's hard to tell the root cause.

https://vorondesign.com/voron2.4

- Fully open sourced

- Repairability and updatability. Lots of fun mods.

- No phone home / privacy issue like Bambu

I think before going down the rabbit hole, it's best to make sure you have a clear answer for this question: Do you care about the learning / tinkering / optimizing part, or do you care more about "it just works" printing?

- Many recommendations in this thread is for the "it just works" printing case. The top candidates are Bambu, Creality, and Eiegoo. The quality is good for most cases.

- If you're an engineer and into tinkering like me, you would be much happier with a Voron v2. Depending on your effort, you can match Bambu's quality, or _greatly_ exceed it.

Regarding Slicer, don't worry much about it. You can learn one very fast. The top ones are Cura and Orca Slicer. I use them both, and they have pros / cons. Personally on my Voron, a well tuned Cura profile yield better result. But Cura is missing one important feature: it can't limit the speed based on Flow Rate.

Another quick tip:

- Take the advertised number with a grant of salt. For example, many printers advertised 600 mm/s print speed. The mechanical frame may be able to handle 600 mm/s, but the Hot End is the limit of the build (e.g. it can't melt material fast enough, friction, the ability of extruder motor to quickly change speed, etc).

Hope you have a great time!

In 2015 SotA models blew past all expectations for engine performance in Go, but that didn't translate into LLM-based Code agents for another ~7 years (and even now the performance of these is up for debate). I think what this shows is that humans are extremely bad at understanding what problems are "hard" for computers; or rather we don't understand how to group tasks by difficulty in a generalizable way (success in a previously "hard" domain doesn't necessarily translate to performance in other domains of seemingly comparable difficult). It's incredibly impressive how these models perform in these contests, and certainly demonstrates that these tools have high potential in *specific areas* , but I think we might also need to accept that these are not necessarily good benchmarks for these tools' efficacy in less structured problem spaces.

Copying from a comment I made a few weeks ago:

> I dunno I can see an argument that something like IMO word problems are categorically a different language space than a corpus of historiography. For one, even when expressed in English language math is still highly, highly structured. Definitions of terms are totally unambiguous, logical tautologies can be expressed using only a few tokens, etc. etc. It's incredibly impressive that these rich structures can be learned by such a flexible model class, but it definitely seems closer (to me) to excelling at chess or other structured game, versus something as ambiguous as synthesis of historical narratives.

edit: oh small world! the cited comment was actually a response to you in that other thread :D

If we want neutral, how about a fair arena for opinions and ideas.. at the moment "The Right" yells and screams "Anti-Semite! Terrorist!" if someone protests against the starvation and slaughter of children... So having them control the medium doesn't feel right for me.

Ok someone's going to come and say that "The Left" controlled the medium and disallowed "non-mainstream" messaging about Covid... I admit my bias and consider such messaging lunacy too..

If the genotype is mostly 'expressed' as depression in certain scenarios that allow your kin to reproduce better at the expense of you reproducing worse, that's not necessarily true.

Imagine for a moment, a version of depression that appears after someone gets their reproductive member cut off (perhaps encounter an angry lion?), but they are still around to compete for food with the extended family's children.

> plus the parts of Syria and Lebanon it occupies)

Well, if Syria and Lebanon didn't want to lose territories, maybe they should not have started wars to ethnically cleans Jews from the place?

I mean, when you start a war with your neighbour with the goal of extermination, you don't get to complain when you lose.

In fact, you should be happy that even though you tried to exterminate them, they didn't try to exterminate you when they won.

Thinking of biology, the reason often given for the disappearance of "unused" genes/base-pairs is that there's a metabolic cost to keeping them around and copying them on every cell division, so they vanish from a form of passive attrition.

I wonder if someday we'll find there's also a more active process, which resembles "remove old shit because it may contain security vulnerabilities."

They apparently managed gold in the IOI as well. A result that was extremely surprising for me and causes me to rethink a lot of assumptions I have about current LLMs. Unfortunately there was very little transparency on how they managed those results and the only source was a Twitter post. I want to know if there was any third party oversight, what kind of compute they used, how much power what kind of models and how they were set up? In this case I see that DeepMind at least has a blog post, but as far as I can see it does not answer any of my questions.

I think this is huge news, and I cannot imagine anything other than models with this capability having a massive impact all over the world. It causes me to be more worried than excited, it is very hard to tell what this will lead which is probably what makes it scary for me.

However with so little transparency from these companies and extreme financial pressure to perform well in these contests, I have to be quite sceptical of how truthful these results are. If true I think it is really remarkable, but I really want some more solid proof before I change my worldview.

But you stated it was "the truth" and so we might reasonably wonder why you think so, unless it's that you just believe anything you read.

"ABI: Now or never" by Titus Winters addresses some perf leaks C++ had years ago, which it can't fix (if it retains its ABI promise). They're not big but they accumulate over time and the whole point of that document was to explain what the price is if (unlike Rust) you refuse to take steps to address it.

Rust has some places where it can't match C++ perf, but unlike that previous set Rust isn't obliged to keep one hand tied behind its back. So this gently tips the scales further towards Rust over time.

Worse, attempts to improve C++ safety often make its performance worse. There is no equivalent activity in Rust, they already have safety. So these can heap more perf woes on a C++ codebase over time.

I miss TkDesk, which I discovered many years ago when I was first trying Linux, partly because it supports unlimited splits, not just two. In fact, if I'm remembering correctly, when navigating to a subdirectory the default was just to open it in a new split. You ended up with splits containing the full path from wherever you started to your eventual subdirectory (you could scroll the view of splits horizontally once there got to be too many).

I'm a European who has emigrated to the US, and knows both sides pretty well.

I agree that European trains work very well for commuting to and from the center of big cities. That's where the jobs and tourist attractions are.

But to go between arbitrary places A and B is usually quite painful. Often the best way is to go to the center, and then from there to your destination.

When I moved to the US and got a car, it was an unreal feeling! I could quickly travel anywhere at anytime!! Practically it felt like my comfortable travel radius increased from 10km to 50km.

I'm definitely excited to see 64 bit as a default part of the spec. A lot of web apps have been heavily restricted by this, in particular any online video editors. We see a bunch of restrictions due to the 32 bit cap today here at Figma. One thing I'm curious though is whether mobile devices will keep their addressable per-tab memory cap the same. It's often OS defined rather than tied to the 32 bit space.
