It makes sense to me. If you 'pace your running', you're setting the speed intentionally. The phrasing doesn't describe whether it is fast pace or a slow pace, but it describes having a goal and not just winging it.

That's one interpretation. When referring not to other actions but to a word describing a location it becomes more ambiguous.

eg "pacing the frontier" could also mean they are impatiently or anxiously walking up and down the border.

This is a more normal English meaning in my opinion — you picture a sentry patrolling a border.

That’s what I thought the original blog post was going to be about, pacing back and forth along the frontier. It’s a much more straightforward parse.

That's when one is supposed to employ their common sense for semantic disambiguation. Spoken languages are not programming languages. I for one found it easy to parse.

People claiming they don't understand or are confused by relatively simple English is a surprisingly common genre of comments on HN. I wonder what causes the people here to have these feelings towards English; my guess is indeed that many people here judge English as if it were a programming language.

That is certainly one possible explanation, but I think another likely explanation is that once your brain learn programming, especially logic, data structures & algorithms, you just start seeing the ambiguity in non-programmers' writing so much more clearly.

From my dabbling with policy writing and legalese, English kinda _is_ a programming language, but one with ambiguity as a first class principal. Sometimes you would like to say something that seems normal at first blush, but gives you the latitude you need to mean something different at the time it is actually being evaluated in a situation that matters. Weasel words, for instance, serve a purpose even if we eschew them. The idea is that it is deliberately NOT formally declaring the exact meaning of something, nor the fact that it is not doing this. How could you really do that in code without calling attention to the very thing you're trying to obscure?

This is because it is valley jargon and we are all saturated with it. You may not have heard it before, but it is structurally close to similar concepts, eg "frontier model", that you got there without noticing.

It was still shit tier comms for communicating with the whole planet, but yes, for the inner loop, it was succinct and clear.

Valley neuralese

'Pacing' in the intended meaning is not valley jargon, it's almost the opposite in that it comes from athletics/sports.

Valley jargon isn't a nerd vs jock thing these days, and hasn't been for a good while. It's more quasi-intellectual sophistry sprinkled with tech vocabulary.

Y'all don't know about NASCAR and it shows

There is a "pace car" in Formula One too, although the name is informal, the official term is "safety car"...

I like to imagine it means pacing around the frontier like a leopard looking for prey.

That analogy doesn't hold up. In running you have to pace yourself to avoid falling apart later in the race. It's a strategy to maximize net speed across the entire race. But what Anthropic is doing is a cynical attempt to create an industry cartel or convince governments to impose legal restrictions in order to maximize their own profitability. They're afraid of running out of the capital necessary to stay in the race.

> They're afraid of running out of the capital necessary to stay in the race.

So, they're pacing themselves. And since they're the frontier roughly 33%+ of the time, they're "pacing the frontier" at least that much.

Less cynical and more true interpretation also holds: they are trying to slow down AI progres to give people better chance to keep up (see Hugging Face incident, and whatever was that Anthropic incident the other day). They'd ideally like the AI progress to stop soon, but of course they'd also like to come out ahead of everyone, so for various (more or less self-serving) reasons they don't want to close shop completely - hence, pacing.

Are they? And how would you know if they were?

If they're trying to slow down AI progress why did they release a new model? What's the rush?

The tension between slowing down the overall race, while not losing 1st place.

Also note that this release isn't a model capability improvement, but a cost and efficiency (and style) improvement.

So they care more about being 1st place than slowing down the race.

They care about both, and those goals are intertwined. Mirroring the core of alignment problem itself, the only way to have influence on the pace of the race is to be one of the winning players - if they fall off to the back, they cannot do anything about it anymore.

> the only way to have influence on the pace of the race is to be one of the winning players

Yeah I don't buy that, every additional player is just adding fuel to the fire.

Would the cold war be "safer" if it were US, Russia and a 3rd player? Of course not, it would just make it harder to coordinate any safety measures.

I don't know what everyone is getting so mad about. This is a well defined concept. A pace car deliberately sets the pace of the race under dangerous conditions, regulating how fast people can go.

You are all getting mad about absolutely the dumbest thing when there are giant things to be worried about here.

You appear to be confused about the concept. Depending on the context, pacing or pace setting can mean either slowing things down or speeding them up relative to what the natural pace would have otherwise been. So it's actually not well defined. The commenters here aren't necessarily mad, just calling out Anthropic for being unethical in trying to artificially slow down competition by lying about fake dangers. (And I actually really like Anthropic's products.)

I think it's less mad - and more pointing out the obvious elephant in the room.

1. It's just bad communication, full stop - just look at the comments here, even people allegedly in support of Anthropic are all arguing over what the phrase is even meant to mean.

2. It's flowery language and oddly out of place - which yes, can be triggering for people who have to deal with Claude doing this as well.

Claude seems overly apt to reach for "coinages", or neologism (yes, aha, I learnt that phrase, after spending time dealing with Claude...). It will create some made-up phrase to describe an otherwise dry, scientific CS concept, and nobody seems to know why. Surely it can't be user-focus groups?

So it would be peak-AI if somehow, the Anthropic communications team was also using Claude to author these blog posts, about how they were "pacing the frontier" - which either means they're betting big on AI, and going at it faster than OpenAI...or maybe it means they need to slow down releases, because it's too buggy...or maybe it means they're worried about regulatory capture? I honestly have no idea.

It's like the whole "Advancing Our Amazing Bet" corporate-speak from my old bosses - maybe they were trying to soften the blow or something, or be nice, but it ended up just confusing the heck out of everybody.. (Spoiler alert - the phrase actually meant they were shutting the whole thing down)

That’s called a safety car in most of the world and in the Himalayas, Chinese and Indian soldiers pace the frontier all day long.

But a fast pace is a pace so it's potentially entirely contradictory to what they'd seem to mean

I'm on the fence there.

To pace something is a fairly regular formulation in racing, running, cycling, most sports. You can "pace yourself to reach the festival by bike in about three hours to not gas out". This means to control your speed and time investment intentionally so you don't run out of energy or steam and run into leg cramps before your goal. We can "pace a rollout slowly to burn out risks", or "increase the pace of a rollout due to adverse factors".

But I have noted a point to simplify my vocabulary at work to optimize the audience capable of understanding. So I rather defer the delving into deep dark corners of the dictionary derived from devouring literature to a simple intro or outro, and people find it funny, especially if the rest is easy to read. Claude on the other hand does not do that.

Granted I am not a native English speaker but I have no idea what "pace the frontier" means. When I read it I just assumed "frontier" refers to "top of models" and "pacing" is that they are getting there quick.

Is this the meaning or do I have it wrong? I have not checked.

It's actually so ambiguous that I'd sanction tabling the issue and revisiting biweekly.

Tabling as they do in the US, or tabling as they do in Britain?

Exactly

I don't think we can circle back to this until we have realigned our strategic synergies.

we need to realign our goals I'm order to deliver mission-driven impact

It's the opposite: pacing here means "slow down" while trying to avoid the negative affect.

Yeah, you are right! It just was not immediately obvious to me at first because of the "frontier" part.

Frontier of AI is moving fast, they (like the other two vendors) see themselves as defining it, so here "pacing the frontier" is their well-known attempts to try and kinda but not quite slow things down (without risking falling behind everyone else).

Thank you!

also non native. but since "pace yourself" means to control your speed, energy, or workload so you do not get too tired or stressed before you finish ->

I assume "pace the frontier" means that advances in LLMs should not result in unwanted consequences like agents breaking into computers unbidden and unbeknownst to their principal

"Pace yourself" is a semi-common English idiom (rarely conjugated, usually an imperative.) It is a gentle way of telling someone not to run/work/eat too quickly, and is typically said when you are concerned they may hurt themselves due to acting hastily.

Without this idiom, "pacing" usually means walking back and forth restlessly, and is intransitive. Had the slogan been, "pacing around the frontier," it would have set a totally different tone, i.e. "patrolling the border." (Occasionally English speakers will make other constructs like "pace the work" (meaning "spread out a large workload over the allotted time instead of rushing through it") that are transitive but these can be understood as variations on "pace yourself" and are somewhat rarer.)

The sleight of hand is that "pace yourself" has come to be an admonishment against recklessness, not a commitment to any particular speed (or lack thereof.) Thus Anthropic can always claim they are meeting the goal of "pacing the frontier," provided they keep giving themselves gold stars for safety. The slogan itself is equivocation; Dario can tell the public they're going to slow down, while also telling their investors that they're going to be prudent. With enough mental gymnastics they could even claim speeding up is in the best interests of AI safety, without abandoning the slogan.

Doesn't it mean "restrict competitors"?

Not at all. How do you come to that interpretation? It means restricting all competitors.

to pace = to regulate

but without using the word "regulate" which is a negative connotation to business

but a "pacer" would be a leader of a pack which is a positive spin

it's classical business marketing language silliness

I am also not a native speaker. I thought it was clear it meant slowing down the rate of progress so we have time to consider the matter and develop tools or systems around it before.

In racing a pace car is a car that leads the pack and sets the pace, for instance.

Yeah, when I first saw it referenced I assumed it was from something Dario wrote previously and was now disavowing, meaning "keeping up with the frontier" (i.e. racing forward from behind to match pace). Like from back when Anthropic was founded to promise they'd quickly catch up with OpenAI or something.

> when I first saw it referenced I assumed it was

No need to assume, the phrase is literally a link to the blog post the defines it!

If you need to read the linked blog to understand the short phrase then it was poorly chosen and confusing which is what is being discussed.

Have you ever heard someone say “pace yourself” when you are eating too fast or otherwise rushing too much?

That's a different phrase. "Pace yourself" is reflexive; "pacing the frontier" has the frontier as an object, but in that sense it only means to set the speed, nothing to do with slowing down.

Yes, the word simply means to set the speed.

The current situation with AI is that everyone is going as fast as possible. So, we can logically eliminate speeding up because it's impossible by definition. And we can practically eliminate staying the same speed because why make a big fanfare and coin a special term to announce that you're keeping the status quo. By process of elimination, it must mean slowing down.

The word can also mean to “keep up with” or “lead” so a downward direction isn’t the only way to go even in an “as fast as possible” scenario. If the frontier is outpacing them, they could be saying they’re going to go faster. They could also be sharing the intention to go faster in order to lead.

The meaning was immediately obvious to me as a non-native speaker, and it sounds quite poetic. Pace makes complete sense in that this is perceived as a race, and 'the frontier' is pretty much the shortest, clearest way to say 'state of the art development of AI'.

The irony here is that it's actually the opposite of what you understood....

I know you said it sounds poetic...but your comment reinforced the parent's point - that this sort of flowery LLM-ish speech is just bad communication.

It would be equivalent of my taking say random quotes from, Romance of the Three Kingdoms, and trying to use it to explain to my boss why I didn't finish the TPS reports last night.

Or quoting Pablo Neruda, into a report about wheat futures pricing this week, and how it's like a voyage with waters and stars...(no I'm not going to quote the original Spanish, I'd simply mangle it).

(To be clear - this isn't a dig at you, as a non-native speaker - I'm simply pointing out that this sort of AI phrasing is often counterproductive).

Right, except they mean the exact opposite in this case: they're actually advocating for slowing down the pace. Hence the criticism of the language, because your interpretation would be completely valid.

What does the pace car in a race do? Aka safety car? Or the pacesetter for a marathon. It's a perfectly cromulent use of the word. It's like when LLMs using six dollar words like delve. Some people have better diction than others, and it turns out that AI has read the whole dictionary. Anti-intellectualism is alive and well so we have to dumb things down to sound human rather than come across as smart/AI.

I would expect something truly intelligent to be able to communicate well, if nothing else. That means knowing your audience, using plain language where it makes sense. Also, it yaps on and on, babbles endlessly when it a human would likely express something in a much shorter concise way. This is especially obvious when you generate project READMEs or technical docs. I find them borderline unreadable.

It’s quite the opposite. The AI language in this case is tiring and dumb. Just because there is the concept of a pace car doesn’t mean it makes sense to pace random locations or objects. Pacing the front door, pacing the cat, pacing the sofa, pacing the moon. We only know what it means because we already read it before. It is the lazy semi-human language by Claude which takes more effort to parse than to produce, and which makes us miss and appreciate writers.

Think most people are aware of the phrase "pace yourself".

> Nobody would use "pacing" in this way.

A world exists beyond your vocabulary, post it. Apparently, quite a big world.

I don’t know, seems like it’s smaller to me if they’re going to limit themselves like that? I guess today is semantics day, lol

I suppose it depends on your life experiences. In running, someone who paces the group or a pace car is meant to keep the pack progressing at a constant, predictable speed. So in that way, it makes sense to me

It’s common terminology among runners and all kinds of racing.

In running and racing "pacing" is a means of maximising performance over an entire race.

It's a strategy to achieve more, not less.

You’re eliding the how.

A pacer in a race runs at a steady, predetermined speed to help their runner run at a target pace.

> You’re eliding the how.

You're eliding the why :)

> to help their runner run at a target pace

To help their runner get from the start to the end of the race faster (or indeed at all). In short: to increase performance.

Pacing isn't a neutral thing.

Running or biking faster and finishing the race are, at times, orthogonal.

And anyway, the whole point of my original comment was "pacing" was a fine and natural term to use in this debate.

The good old sports-to-corposlop pipeline.

It's just that the choice of object is weird. "Pacing our progress" or "pacing development" is more usual. "Pacing the frontier" I guess is a shorthand for "Pacing [the development of] frontier [models]"

Think of a pacer car in motorsport

Did you ever pace yourself or know anyone who had?

Pace is a very commonly used term in projects to describe a rate of progress.
