I’ve had this same idea, and it doesn’t work. Or at least: it works quote well, but the problem is that you get hallucinations. And it can be incredibly discouraging to find out the flashcards you’ve been cramming are completlh wrong.


I've had this same problem using ChatGPT and German. Even for basic German hallucinations can be unexpected and problematic. (I don't recall the model, but it was a recent one.)

In one instance, I was having it correct akkusativ/dativ/nominativ sentences and it would say the sentence is in one case when I knew it was in another case. I'd ask ChatGPT if it was sure, and then it would change its answer. If pressed further, it would again change its answer.

I was originally quite excited about using an LLM for my language practice, but now I'm pretty cautious with it.

It is also why I'm very skeptical of AI-based language learning apps, especially if the creator is not a native speaker.


Would agentic workflows come in handy in these cases? I mean having a controller agent after the sentence is created, where this agent would be able to search the web or have access to a database? or personal notes and ensure everything is correct.


Maybe? I suppose it depends on the quality of the controller agent, which then comes back to the quality of the original LLM.


What models have you been using for that? While I haven’t tried automating the production of vocabulary lists through an API, within the last few weeks I have had the chat versions of ChatGPT 4o, Claude Sonnet 3.5, and one of the latest Gemini models produce annotated vocabulary lists based on literary texts in English, Russian, and Latin. I didn’t spot any hallucinations.

I was asking only for the meanings of the words and phrases, though. I didn’t ask for things like pronunciations, grammatical categories, etc. In the past, when I’ve tried to get that kind of granular information from LLMs, there were indeed errors, presumably because of tokenization issues.

A few days ago, I ran some similar tests with Japanese, asking for readings of kanji and jukugo in an extended text. All of the models I had tried before for such tasks had screwed up. This time, however, ChatGPT o1 scored 100%. It also was able to analyze sentence grammar accurately, unlike the other models I tried. I was impressed.

At current API prices, though, o1 might be a bit too expensive for such a task.


I wonder if there are any benchmarks specifically designed to evaluate LLMs' performance in language learning tasks


I haven’t heard of any. It would great if there were....


I had this problem initially but found that if you use these then hallucinations mostly go away.

1. Role based "agents" with a router and logs (for auditing reasoning and decision making).

2. Cross validation and redundancy with the translation "agent" using a 2nd language (that is not English) that you are also native in to check if the translation carries the same "meaning" (sentiment) and cultural significance (Turkish is especially rich in symbolism and cultural memes).

YMMV: I am a car salesman irl and have no formal training.


I'm not sure if you're from the Netherlands, but I can assure you it's more nuanced that this. Mixing only works when cars are not dominant, so you need low car volumes and low speed in these areas. Residential areas in cities are an example of this: no through traffic, max 30kmh limit.

Most of (new) Dutch road design is designed to give pedestrians and cyclists multiple safe options, while cars have to take the long way round. You can in theory still get basically anywhere with a car if you need, but often (especially in cities) it easier to walk/cycle/take the train/tram/metro. The result is that things can be closer to each other (no parking moat everywhere) so in the end the trip is shorter and safer for everyone, including people choosing to take the car.


As an example: More and more "cars are guests" roads are being added. These are usually cycling dominant routes and while completely removing cars might be preferable it's not always possible. Due to the roads being designed as widened cycling paths (and look like it) which barely fit a car you can have cars there but you'd think twice driving there, which makes the drivers more cautious and lowers the car traffic volume a lot. Note: the throughput of a cycling path far exceeds that of a normal road per surface area used (about ab order of magnitude vs cars).


I would argue the point of the article isn’t “we need more bollards everywhere “, it’s “our regard for pedestrian safety is absurdly low, even cheap tools to increase pedestrian safety (like bollards) are uncommon / controversial"


If the harm to society is 1M$ per car, should we be driving them at all?


No, we shouldn't. But the cost of installing bollards and the "harm to society" are two distinct costs. There are about 2.37 pedestrian deaths per billion vehicle miles traveled in America. Even if we assign a generous cost of 5M$ per life lost, that only amounts to a 0.01$ per mile driven, which is probably not enough to cover the cost of installing bollards all over the place.


How about 10 bollards per sold car, you can probably get away with $ 1k per bollard (including installation), most cars cost a multiple of 10k. Let‘s see how far that gets you. You can of course modify the bollard tax by car weight or by price.


So $10K extra per car? Assuming we're talking the US here where the average price of a new car is under $50K, that's more than a 20% bollard tax.


The average price is really that low? Do you have any pointers/data?


This Fortune article[0] lists an average as of January of $47,338, I believe based on Kelley Blue Book.

Not in the cloud.


It's all fun and games until the websites you need (bank, local government, etc) only support the pipes build by a tech corp in a faraway country. Diversity is good and healthy.


>until the websites you need (bank, local government, etc) only support the pipes build by a tech corp in a faraway country

they don't get to decide this if push comes to shove. Banks and governments in European jurisdictions obviously can be forced to comply with European laws and if there was some geopolitical question about security you can just force them to switch to a local fork of Chromium which given that it's open source is technically relatively trivial.

It's the same as Linux essentially. The overwhelming majority of commits comes from RedHat, Huawei and Samsung or other international corps which is fine because there's always the implicit option to fork it. We don't need fifty different kernels given that we're talking about open source software. In the olden days of Internet explorer and dependence on proprietary software this argument made sense because you could theoretically be squeezed without an ad-hoc alternative, but that's not the case any more.


We are on the same page here.


And also basic levels of German and French. Outside of tech I actually hear from multiple sources German is an important language for trade between medium-sided companies, to Germany of course but also a large portion of the other eastern EU members.


This sounds like a very American answer. Have you been to such an event in any other place, like Europe?

Near me is the largest open air weekend market of the Netherlands. Do you know how everybody gets there? By bike, public transportation, walking, etc. And then some small percentage that arrives by car.


> This sounds like a very American answer. Have you been to such an event in any other place, like Europe?

Of course, and I've been to the mecca of public transit, Japan!

And guess what -- outside of the super-dense cities, most Japanese people drive cars. I spent some time in a Japanese city about as dense as a California suburb. Two train stations in the entire city. A car or two in every driveway. I've also been to smaller cities in various European countries and it's the same story.

People need to stop pretending that the world looks like Copenhagen or Tokyo. In reality, most of the world is not dense.


This is an article explicitly about _urban_ mobility. If you're going to exclude large, dense metropolitan areas, are you even addressing the arguments being made here?


Define "urban".


from google: "in, relating to, or characteristic of a town or city."

I am not sure what point you are trying to make


The point is that bicycling is not realistic outside of very, very dense cities. Most places that reasonable people call "cities" would not qualify. Even in Europe and Japan, which have world-class public transit, only a handful of cities have useful subways or usable bicycle infrastructure. Everywhere else, people drive cars.

People who are advocating for bicycles as a primary form of transit are using a hyper-narrow definition of "urban," in which most cities would not be considered urban, and that is deceptive and wrong.


The word dense is in the second sentence of the wikipedia article on cities. It is inherent to discussion of urban transportation. You seem to be using the word city loosely, but it's a rather specific term.

Even though I agree the policies here apply to a small fraction of the world's area, it affects a sizable fraction of the population.


> The point is that bicycling is not realistic outside of very, very dense cities

Bullshit. I grew up in a small village -- 300 people or so live there. It's a couple of kilometers from two other villages in the 2000-500 range. There's one school for the area shared between the villages. The daycare I went to was located in one of the other villages. I biked (alongside my parents) for 5 kilometers on non-separated roads to get to daycare at the age of 4. I biked first 2 kilometers to school every single day until 7th grade where I then had to bike 12 kilometers each way. It sounds tough if you don't bike. If you've done it your life whole it's just a mode of transport. Taking 30-40 minutes on the bike was faster than taking the bus too.


It's not dense because the same people opposing pedestrianization also oppose density.

If we let people build a couple Amsterdams or Londons in America, we could just self select and those that want to cycle and walk can do so, and those who want to drive can do so - just in separate places.


Having lived and traveled all over Europe without a car, I can say with confidence that urban environments of a wide range of density are incredibly well-served by public transit, pedestrian routes, and bikes. Cars are necessary in lots of cases, but the vast majority of day-to-day activity that requires a car for me here in the US would have been silly to use a car for in Europe.


My European city in Portugal, has several routes that have one bus per hour, stop at 21h, and decrease their routes at weekend.

Shoppings and several city services are located on the city outskirts only reachable by car or taxi.

You can cycle around on the city centre and then enjoy the roads that are organised like motorways around the center.


Copenhagen is not super-dense, not even very dense. Berlin is even less dense than Copenhagen, yet both cities are very pleasurable for using the bike as your sole means of transportation.


Copenhagen would be the 3rd densest city in America and would represent less than 1/3 of a percent of the population. America is huge with a ton of space and people have spread out.


> , most of the world is not dense.

But most people in Japan live in the super-dense cities. So we are literally discussing solutions that work for most people


It's funny that foreigner says Japan is fine without personal cars. That's because tourists don't visit random local middle sized cities.


And yet ~70% of Japanese households own cars.


Owning a car and using it daily is not the same thing.


Yes, you are right. Bikes make sense only in dense urban areas or if you're relatively close to commerce or work. That's still a big minority of people, but getting onto bikes and out of cars is great where it's a possibility.


If you aren't that close, you can have hybrid transportation. Take a bike to a bus or train.

Better zoning would help too.


> most Japanese people drive cars

Citation needed.

People who drive cars usually have a need for them. Cargo hauling for example.

> Two train stations in the entire city.

Probably wasn't a large city. I've been to some really small cities that had two train stations. You could walk between stations.

> A car or two in every driveway

For the most part, Japan doesn't have driveways. Even in less populated centers, they might have a parking space, or a garage, but not a driveway. It's a waste of space. Even street parking is limited. Some people may have two cars for whatever reason but I doubt that is the norm.

I'm wonder what region you were at that saw this many cars.

Interestingly, the number of cars in Japan is roughly the same as the number of bikes in circulation.


46% of people use their own car for commute in Japan, but it's 9.5% in Tokyo. Sorry this is written in Japanese but you can use translate. https://todo-ran.com/t/kiji/18920


Lots of fat Germans, Polish, Hungarians, and British. Heven't visited other European countries, so couldn't tell you about others.

As to a solution; How about recumbent trikes? Beats dissing foreign nations based on biased preconceptions of healthy lifestyles.


Yes, unless you happen to live in top European cities, those that make the top list where to live in Europe, you get there by car.


Well, it can also be pure randomness


They did say “ruling out chance”.


Dutch person here. I believe the driver is at fault, unless it can be proven that the cyclist had a serious part in the crash.

Having said that, there is significant effort made here to just reduce conflict points between modes of transport. No law can help you if you're dead.
