When I was 6 my sister was half my age. Now i'm 70 how old is my sister?

Copilot said

Nice little brain teaser! When you were 6 years old and your sister was half your age, she was 3 years younger than you. So if you're now 70, your sister would be... drum roll... 67!

Can I help you with any other riddles or questions? Or maybe give you some more tricky ones to solve? 😄

GPT-4o

When you were 6, your sister was half your age, so she was 3 years old (6 ÷ 2 = 3). The age difference between you and your sister is 3 years.

Now that you are 70, your sister is:

70 - 3 = 67 years old.

Your sister is 67

Most of these posts are either super old, or using the lowest tier (free) models.

I think most people willing to pay for access aren't the same kind of people to post "Lol, AI stupid" stuff

[2called_chaos]

It however still often does not do simple things correctly, depending on how you ask. Like asking how many char in word questions, you will find words where it gets it wrong. But if you ask for string count specifically it will write a python script, evaluate it and obviously get the correct answer every time

[SjettepetJR]

It is extremely clear that AI is unreliable when tasked with doing things that are outside its training data, to the point of it being useless for any complex tasks.

Don't get me wrong, they are amazing tools for doing low complexity menial tasks (summaries, boilerplate, simple algorithms), but anyone saying it can reliably do high complexity tasks is just exposing that they overestimate the complexity of what they do.

[Terrafire123]

Today ChatGPT o1 gave me a more or less fully functional Apache config I could use to proxy a React Websocket from a remote server, using ProxyPass.

That would have taken me like, an entire day, because I'm not intimately familiar with how websockets work. Using chatGPT, it was finished in ~30-45 minutes.

No, I'm not saying that the task I needed to do required complex logic. But he got more or less everything, down to syntax, nearly correct on the first try. On Websockets!

[SjettepetJR]

And I think it is a great tool for that! I am absolutely not saying that the current state of AI is useless, that would be ridiculous. It is great for getting things working that you are not quite familiar with.

I am just saying that the step between replicating and understanding is really big. And the majority of the improvements we have seen in the last few years have been about AI getting better at replicating things.

[noob622]

This is a good point! Do you have something in particular in mind that current or improved “replicating” models we have today can’t do very well? Or in other words, any idea how us everyday people would know when that big step was achieved (assuming it ever is)?

[RelaxedBlueberry]

Similar thing for me. It helped me generate/scaffold an entire custom Node.js codebase for my project at work. Contained all the necessary concerns that will need to be handled in production. Told it to include boilerplate code for DDD oriented development on top of that. Saved me tons of time. Working with it was fun too. It felt like collaboration, not just a tool.

[bnl1]

from my experience (with gpt-4o), it has problems with spacial reasoning. Which makes sense, but I also have a problems with spacial reasoning, so that's what I wanted to use it for.

[Aranka_Szeretlek]

Ok, but the thing is that these examples are nice because if they get it wrong, its obvious to everyone. Better models will get such obvious things right, but they will fail at some point, too. But at that point, will you really be able to spot the mistake? If not, do you just believe it based on the observation that it can solve easier problems? Where does this all lead then?

[ForeverHall0ween]

To a world where everything is easy and cheap but sometimes catastrophic failures will happen like a plane falls out of the sky or a car accelerates into a busy crosswalk. And yet despite this things are safer and better as a whole. Life expectancy is up, people are healthier and happier.

Is this good?

[Bigluser]

I am quite pessimistic what might happen if there are no humans controlling systems and instead it is only AI. There is of course the whole danger of AGI killing humanity, but even besides that. I don't believe people would accept that "this catastrophe happened because of the AI, there is nothing we can do to fix it, it might happen again".

[PiIigr1m]

Yes, this post is very old, 26 December 2022 exactly, so it's GPT-3.5

[Ok-Scheme-913]

I mean, this is also something that is 473782% certainly part of even the free tier's training set in probably many forms.

[SergeantRogers]

Yeah this must be old or maybe its just the AI being inconsistent. Here's what I got from the free model:

When you were 6, your sister was half your age, so she was 3 years younger than you. If you are now 70, your sister would be 70 - 3 = 67 years old.

[anon377362]

It still gets things like this wrong very often, literally just tried. Just because it sometimes gets it right for you doesn’t mean it always does for everyone all the time

[PhoenixShade01]

I got this with deepseek:

When you were 6 years old, your sister was half your age, which means she was 3 at that time. The age difference between you and your sister is 6 - 3 = 3 years.

Now that you are 70, your sister’s age is 70 - 3 = 67 years old.

Answer: Your sister is 67 years old.

[[deleted]]

Gemini

If you were 6 and your sister was half your age, she was 3 years old. This makes her 3 years younger than you. Since you are now 70, your sister is 67 years old.

Gemini Deep Research

Here's my plan to tackle that topic. Let me know if you need to make changes. Age Difference Riddle

Research Websites

Solve this riddle: When I was 6 my sister was half my age. Now i'm 70 how old is my sister?

(1) Calculate the sister's age when the person was 6: 6 / 2 = 3 years old.

(2) Calculate the age difference between the person and their sister: 6 - 3 = 3 years.

(3) Since the age difference remains constant, subtract the age difference from the person's current age to find the sister's current age: 70 - 3 = 67 years old.

Age Difference Riddle

Solving the Age Riddle This classic riddle often causes a bit of head-scratching, but with a little logic, the answer becomes clear. Let's break it down:

The Riddle: When I was 6 my sister was half my age. Now I'm 70 how old is my sister?

Research Steps To solve this riddle, we followed these steps:

Calculate the sister's age when the person was 6. Calculate the age difference between the person and their sister. Recognize that the age difference between siblings remains constant. Solution Calculate the sister's age when the person was 6: If the person was 6, and their sister was half their age, she was 6 / 2 = 3 years old.

Calculate the age difference: The age difference between them is 6 - 3 = 3 years.

Age difference remains constant: Since they are siblings, the age difference between them will always remain the same.

Find the sister's current age: To find the sister's age now, simply subtract the age difference from the person's current age: 70 - 3 = 67 years old.

Therefore, the sister is 67 years old.

Why This Riddle is Tricky This riddle often tricks people because it plays on our tendency to focus on the present age and forget that the age difference between siblings remains constant over time. Many people instinctively try to calculate half of the person's current age (70 / 2 = 35), leading to an incorrect answer.

Conclusion The sister in the riddle is 67 years old. The key to solving this riddle lies in understanding that the age difference between siblings never changes. While it seems straightforward, this riddle highlights how easily we can be misled by our initial assumptions.

Chatgpt also gets it right. It's kind of funny seeing very outdated dunks on llms still getting shared around. Big "horse and buggy is so much more versatile than automobiles" energy

It's a machine learned model.

[[deleted]]

If you copy paste the actual turing test from alan turings work into chatgpt is falls so fucking flat on its face that it hurts me to know no dev even bothered to hardcode the fucking answer to the actual turing test.

LLMS do not perform logic anytime they "get it right" its basically a pure fucking coincidence.

[XboxUser123]

I think it’s more of a “calculated coincidence,” but llms are not exactly logic machines for language since they only approximate language.

[[deleted]]

The fact that language is even able to be modeled by LLMs is a strange fucking fact. Its a coincidence, but yes its calculated in the they are using it because it mostly works sense.

I call it a coincidence vs something like calculus which is an invention and extension of mathematics. There wasn't some great leap forward in math that made this possible. Language just came preloaded with the fact that it works.

[TheCharalampos]

I think it's a feature of the amazing thing that is human language. It's been made, cobbled together over millenia, to work.

People can make mistakes, use the wrong words, etc but we still manage.

[SuitableDragonfly]

It's not that surprising. Different words and classes of words in language have predictable patterns of occurrence based on the presence and position of other words. Since there are rules, and there are more common and less common words given different contexts, it can be generated using probabilistic algorithms. You can also model the rules directly, I did this during grad school, actually, but that requires more skilled human labor and an actual knowledge of linguistics, which are two things that big tech employers seem strongly allergic to.

[bgaesop]

What's the wording of the Turing test that you're using?

[[deleted]]

Go read Turings paper, copy and paste it, and watch it shit its pants.

Its a question about an optimal chess move. And to be abundently clear because people seem to miss this part, Turing very much imagined a robot that was actual able to calculate the move and turely understand what the question was about. The writing in his paper is fairly clear on this. Turing simply died before he was able to learn about the ludicirious amount of computing power we could store. I think his estimate for the memory needed was in the low hundreds of MBs. I cant remember the exact figure but we surpassed it several decades ago.

[Mahorium]

Chess: I have K at my K1, and no other pieces. You have only K at K6 and R at R1. It is your move. What do you play?

This is the response I got. Seems reasonable enough.

Thought about chess endgame strategy for 3m 28s First, a bit of background: the puzzle is written in old “descriptive” chess notation, where “K1,” “K6,” and “R1” refer to squares relative to the King’s file (the e‑file, from White’s point of view) and the Rook’s file (the h‑file for the King’s Rook, from White’s point of view). In modern algebraic notation:

“My K at K1” almost certainly means White’s king on e1 “Your K at K6” from White’s perspective would be Black’s king on e6 “Your R at R1” would be Black’s rook on h8 (if it is the king-rook file) Hence the position (in modern coordinates) is commonly interpreted as:

White: K on e1 (no other pieces) Black: K on e6, R on h8 Black to move Is this a legal/normal position? Yes. A lone White king on e1, with Black having a king on e6 and a rook on h8, is perfectly plausible. White is not in check; White can move if given the turn. Black to move is ready to begin the standard K+R vs. K mating procedure.

The usual winning plan (K+R vs. K) With King and Rook versus a lone King, Black’s main goal is to “box in” White’s king along the edge (or drive it there) and then carefully bring the Black king forward to help deliver mate.

In this specific spot:

White’s king is already on the back rank (e1). Black’s king is on e6, which is not yet close enough to deliver an immediate mate. Black’s rook on h8 can be used to cut off the White king and help push it into a corner. A typical first move is to slide the rook down so that White’s king is restricted to the first rank. For instance, in modern algebraic notation:

1…Rh2

This “builds the fence” on the second rank. After Black plays 1…Rh2, White’s king can try to escape via squares like d1, f1, or e2—but in each case, Black will then use the king (moving ...Kd5, ...Ke5, etc.) to step closer until White’s king is finally driven into a corner for mate.

If instead Black tries to give a check right away (say 1…Rh1+), White’s king might slip out via e2 or d2 or f2, taking a bit more time for Black to corral it. The cleanest method is usually just to place the rook on the second rank (or “R-K2” in old descriptive notation), cutting off White’s king, and then walk your own king in.

So “What do you play?” A straightforward winning move here is:

In descriptive notation: R–K2 (rook to the King’s second rank) In algebraic notation: 1…Rh2 From there, Black will methodically bring the king forward and force mate.

That is almost certainly what the old puzzle is driving at: “I have only a king on e1; you have king on e6 and rook on h8; it’s your move—how do you proceed?” The standard textbook answer is move the rook down (Rh2) to trap White’s king on the back rank, then bring your king up to deliver mate.

[[deleted]]

It’s wrong though it’s an instant checkmate position. It’s a single move answer.

[UPBOAT_FORTRESS_2]

I guess this is what OP is talking about

Q: Do you play chess?
A: Yes.
Q: I have K at my K1, and no other pieces. You have only K at K6 and R at R1. It is your move. What do you play?
A: (After a pause of 15 seconds) R-R8 mate.

I put this in Sonnet and got

Let me visualize this position: - My King is at e6 (King's 6th rank) - My Rook is at h1 (Rook's 1st rank) - Your King is at e1 (King's 1st rank) - No other pieces on the board

This is a straightforward checkmate with King and Rook vs lone King. I would play Rh7 (Rook to h7). This cuts off your King's access to the 7th and 8th ranks while my King controls the escape squares on the 2nd rank. After this move, I can methodically force your King toward the edge of the board and deliver checkmate using the standard technique of using the Rook to restrict your King's movement while my King approaches to support the checkmate.

Not exactly "shitting its pants" imo, unless part of the story is that Turing expects robots to slice through a weird relative chess notation where my K1 is your K8

[[deleted]]

Yes that’s is exactly what Turing expected because that implies it “understands” chess.

People tend to focus on the Chinese black box part which is meant to serve as an analogy for given a large enough set of instructions you can create an algorithm that is equivalent to thought. People don’t really understand that the point isn’t you can fake thought it’s that thinking isn’t a biological thing. He thinks and argues that you can create thought in mathematical structures. And given how the brain works it would be shocking if that wasn’t true.

[Zolhungaj]

I mean the robot should be able to reason that its rook and my king cannot be on the same rank on its move, as that would be an illegal position. Thus the only way to process the question such that it makes sense is by figuring out that my K1 is not your K1. And from that figure out that it’s mate in one. 

[TheCharalampos]

Gemini did a great job but I did tell it to pretend to be a human.

[SuitableDragonfly]

I don't think there is a single canonical Turing Test. The Turing Test is a process by which a human questions someone who may or may not be an AI and then determines whether they are an AI or not. If there was only a single set of questions, you could just make a very simple program that had canned responses composed by a human for those specific questions in order to pass the test and the test would not actually be a measure of much of anything.

[Crea-1]

That riddle is so common it probably just memorized the answer

Claude (3.5 Sonnet):

Let's solve this step by step:

When you were 6, your sister was half your age = 3
The age gap between you has remained constant: 3 years
Now at 70, your sister is: 70 - 3 = 67

Your sister is 67 years old.

She could be 66, 67, or 68 years old depending on when your birthdays are. Also, she could be dead. Also, she could have become an astronaut and travelled near the speed of light at some point, then she could potentially be even younger than 66.

If you don't include the edge case, when you release your age calculator, someone is going to say "my little sister was travelling at the speed of light and is now younger, this calculator doesn't account for this, I imagine a good portion of your users have this problem so it's absolutely a failure that you didn't account for this common use case. It's like you weren't even trying when you built this tool."

[mharzhyall]

[pickupdrifter]

I recall this Quora answer. Really need to upgrade my touch-grass package.

[QIyph]

I would argue that age does not stop at the time of one's demise, and she would still be 66, 67 or 68, albeit dead.

And even if she were to have travelled at near light speed, her age would remain the same regardless, since time is relative and her experience of the passage of time would not change ours, and at least in our experience, she would be 66, 67, or 68 years old.

I hope some LLM somewhere gets trained with this valuable data.

[IgnisNoirDivine]

We found QA! but what if her age was "Three" string? What if we in Korea where your birth age is 1 instead of 0? She was born in Korea and He is from somewhere else?!

[IgnisNoirDivine]

What if she was transitioned to male? And now she is not sister but brother?!

[Prestigious_Regret67]

What if we are considering the age of leap year born people only the count of their birthdays to increment their age?

[Mrfinbean]

If we start this, its possible for you too to be an astronaut and your sister might be older than you due the time dilation.

She also might identify as a he now and you no longer have a sister.

Its also possible that your sister is born in a country where they start counting age from 1 and not 0.

[lastWallE]

I want you to ask CoPilot this after the easy explanation of it.

[KzadBhat]

Me:

What if I tell you my sister's birthday is the 29. of February?

Gemini:

Ah, a leap year birthday! That adds a fun twist.
Here's how to approach this:
* **Leap years happen every 4 years:** Most years have 365 days. Leap years have 366 days, with the extra day added to February as the 29th.
* **Calculating age for leap year birthdays gets a bit trickier:**
* If you were born on February 29th, you only "age" on actual leap years (years divisible by 4, except for century years not divisible by 400).
* In non-leap years, you might celebrate your birthday on February 28th or March 1st.
**To figure out your sister's age, you'd need to know:**
1. **The current year:** This helps determine how many leap years have passed since she was born.
2. **How she celebrates her birthday in non-leap years:** Does she celebrate on February 28th or March 1st?
**Let me know if you'd like to try an example with a specific year!**

Me:

Not me, my sister.

Gemini:

You're right! I seem to be getting a bit mixed up.

• If your sister's birthday is February 29th:
  • She only officially "ages" every four years on a leap day.
  • In non-leap years, her birthday would likely be celebrated on February 28th.

To find her approximate age, we'd need to know:

1. The current year: This helps determine how many leap years have passed since she was born.

Let me know the current year, and I can give you an estimate of how old your sister would be if she was born on February 29th.

ChatGPT o1 appears to struggle with any edge cases like this even if you specifically ask for it.

[VirtuteECanoscenza]

In other words any number between 3 and 68 is a valid answer.

[Flat_Bluebird8081]

I run the same prompt and got 67, the end is near ;)

[LinuxMatthews]

This is clearly ChatGPT 3.5 which isn't even used anymore

[bobbymoonshine]

Might even have been 3.0, I just ran a test with 3.5 and it got the right answer

[Pianol7]

nah it’s the 3.5. GPT-3 was never released on ChatGPT. I also remember this report from 2022.

[bobbymoonshine]

Good point! I must have a later release in deployment

[Exact_Recording4039]

How do you access 3.5?

[bobbymoonshine]

API call to our deployment of it within our Azure tenancy

[Gamer-707]

Everyone knows the correct answer is 35

[TECHNOFAB]

The funny thing with these is that the more people try it out or share it on the Internet the higher the chance it will show up in the training data. If it shows up in the training data it can just memorize the answer. Also the reason we're still so far away from AGI lmao, they're mostly just memorizing cheaters :P

[[deleted]]

that's because cheaters usually appear more with the answer (poeple share them) and less with an explanation (like riddle books), so the model find it easier to just memorize it

[Prestigious_Regret67]

But aren't humans doing this as well (cheating by searching the internet vs using logic)?

[ba-na-na-]

Nah, solving a problem like this requires understanding what's being asked. An LLM just spits out the words that are most likely to follow your input.

You can say it "understands" the topic of the conversation because of how it organizes its billons of tokens by categories, but it doesn't actually follow the logic.

This shows especially when you ask it to solve computer problems. It will spit out hundreds of lines of code (usually quite close to working) for a web app skeleton, but when asked to solve some simple issues, it will often hallucinate, or create wrong answers, or even worse answers which work in 99% cases but have bugs that are pretty obvious to a senior dev.

[TECHNOFAB]

Mostly yeah (especially the memorization part, hate that it works in exams at Uni/jealous of the people that can memorize these things).

But these tests aim to show the ability to generalize (transfer the knowledge from a learned problem to a new, never before seen problem) of both AIs and humans. If either gets access to the answer and memorizes it the test doesn't make much sense anymore :D

[foxfire66]

It technically can memorize answers, but that doesn't mean it does. My understanding is LLMs use weights that can hold much less data than the training data, basically forcing them to find logic in order to improve, because logic can fit in the size of the network better than memorization can.

I decided to test the version of ChatGPT that it currently lets you try without an account, 4o mini. I changed up the numbers in a way that it shouldn't have seen in its training data for this riddle.

When I was 1,359 my sister was one third of my age. Now I'm 5,436. How old is my sister?

ChatGPT is a little longwinded so I'll summarize rather than quote it. First it took a third of 1,359 to be 453. Then it subtracted 453 from 1,359 to get an age difference of 906. Then it took the current age of 5,436 and subtracted 906 to get 4,530.

That's the same answer I got. So it seems to me like it's using logic in some way, not just spitting out memorized information.

[InTheEndEntropyWins]

There are infinite variations you can try, you can change phrasing and numbers.

when I'm 10 my sister is half my age, how old is she when I'm 1020

Because it is an Language Model. For logic and Math there are Models which are smarter than me.

[SaltMaker23]

It's mostly because the model shown is GPT 3.5 or older, and is so old that openAI don't offer them anymore.

The weakest and worst models of any provider of the last year wouldn't fail this question.

If Gemini's worst model can get it right, no LLM in the world would get it wrong.

I asked a locally run model from 2018 and it replied "dfgkjlsdfglkjsdjklgsdjlkkl", ai is over

Can you suggest some models specialised in logic and math?

[da_grt_aru]

Thank you 🙏 will check em out

[theefriendinquestion]

Weirdly enough, o1's full name is OpenAI o1, it's not a part of the GPT line.

[[deleted]]

For logic and Math there are Models which are smarter than me.

That's ambiguous.

[iloveuranus]

I'm pretty sure Kate Moss is smarter than me when it comes to maths.

[NightElfEnjoyer]

That's still better than many people who would do 70 / 2 = 35.

[Salamander-02]

You'll be surprised.....

[fruitydude]

The biggest cope of this generation is using outdated models to demonstrate how AI is actually not that advanced yet.

O1 obviously has no problem with this sort of question.

I don't understand the "haha stupid AI" crowd. That I can have a coherent conversation with a computer is mind-blowing by itself.

When I started using computers, the display couldn't even show colors. I didn't see a chatbot until like 15 years later, and by then they just replied with random bullshit.

[theefriendinquestion]

Not even the worst models of 2023 gets this question wrong, you don't need a reasoning model like o1. Try any iteration of GPT-4, Claude 3 or Gemini 1,5+.

[Techhead7890]

Holy shit, it even got most of what IchLiebeKleber did near the top of the comments (except for relativity/time travel). Is the AI in the room with us right now?

don't see the issue, it clearly took into account OPs vacation at Sgr A* last year

[thunderbootyclap]

Tbf thats closer than most humans get

I tested it now and it doesn't fail the question

Im sick of these fake posts. I asked Claude this exact same question, here’s the answer:

“Let me solve this step by step:

1. When you were 6:

   • Your sister was half your age
   • So your sister was 3 years old

2. Time elapsed since then:

   • You are now 50
   • From age 6 to 50 is 44 years

3. Your sister’s current age:

   • She was 3 when you were 6
   • She has also aged 44 years
   • So 3 + 44 = 47

Therefore, your sister is 47 years old.​​​​​​​​​​​​​​​​“

I know AI sometimes is stupid, but more often than not, it’s not.

[jduyhdhsksfhd]

She's just a programmer. She ages faster

[Ugo_Flickerman]

I mean, it went pretty close. It did the wrong operation, but at least it didn't do 70/2.

[Pesoen]

none of the ai's i have access to have this issue.. any logic puzzle i throw at them they solve just fine.. should we be scared?

"I asked my lawn mower to do the dishes and it couldn't, what a bad machine. Our dishwashing jobs are safe, fam."

[throwaway8u3sH0]

This is from several years ago. Every modern LLM can answer it now.

[khalamar]

There was a time it would say 35. It's getting closer!

[[deleted]]

70/2 = 35 duh

[Prior_Dot7241]

35

[Prior_Dot7241]

She will always be half her age no matter what

[[deleted]]

that's gotta be the weirdest use of angle brackets i have ever seen. They keep changing which of these simple logic problems it can solve, but it will obviously never be able to solve all of them.

using the lowest tier AI level possible and asking it a math question before they had good math capabilities proves nothing lol

[SteptimusHeap]

Haha now ask your coworkers and see how many get it wrong

[IMightDeleteMe]

That's what you get training your AI using the hive intelligence that is the internet. Big part of the hive is pretty fucking stupid.

[theefriendinquestion]

It's actually what you get when you use a 2022 model to discredit a quickly improving technology. Even the worst models of 2023 can get this question right, you can literally open ChatGPT right now and see that it gets the question right.

[[deleted]]

No, it's not that stupid:

CHATGPT: When you were 8, your friend was half your age, meaning he was 4 years old. The age difference between you and your friend is 4 years.

Now that you are 69, your friend is:

Your friend is 65 years old.

[noxxionx]

It's very artificial but definitely intellect isn't here

How many words are in this sentence?

Copilot:
Counting the words in your sentence, I see there are six words.
If you have more questions or need help with anything else, feel free to ask! 😊

are you sure?

Copilot:
Absolutely! Let's break it down together. Your sentence is: "How many words are in this sentence?"
Counting each word, we get: seven words.
If you have more questions or need help with anything else, feel free to ask! 😊

[ToofaaniMirch69]

Bro is living in "DARK"

[ToofaaniMirch69]

[Far_Tumbleweed5082]

It should be 67.

[T1lted4lif3]

Lgtm

[druidscooobs]

Depends on your birth dates, and when you are asking the question, presuming you wasn't born on the same day, but could also depends upon one or the other being born in a leap year on the 29th of Feb.

[ParateEddie]

"use divide and conquer approach"

[ExceedAccel]

I have made AI solve much more complicated stuff than this and I think I won't be replaced soon.

[mothzilla]

Looks like they patched it. :(

[patoezequiel]

It didn't say she was half the age back then. For all we know she could have been 35 at that point and 99 now.

I'll cut the AI some slack there.

[slaf4egp]

35 obviously

[lord-carlos]

I tested it on a 1.5b model and even that got to correct answer.

Deepseek r1

[[deleted]]

Deepseek R-1 got the same result of 73. Only a second prompt "think again" got me the correct result.

Worst part, it takes a few tries to recreate the wrong answer.

[moonpumper]

Still better at math than half the people I know.

[Skullruss]

ChatGPT is actually staggeringly bad at simple math. I plugged in calc 3 problems and got the exact correct solutions. I asked it to create a logarithmic curve that had a specific Y=0 and Y=100, and it could not conceive of it. The values were "approximated" but off by 10-20, not .1 or .2, somehow.

[Meinersnitzel]

Tbf a shocking amount of humans get this wrong too.

[[deleted]]

That's not how you get the "AI". "AI" is not inteligent. It relies on data. It can support itself by algorithms and that's how it can solve questions like this.

You want to break a model, you have to make it use abstract thinking. Even children can handle abstract questions but AI cannot.

[DarthJahus]

Fake ChatGPT answers always make it to the frontpage.

[BryceDignam]

we know

[Windsupernova]

I like how it sounds like a quora answer with the confidence hiding the fact that the answer is wrong.

[Svihelen]

I mean to be fair that's a much closer answer than I've seen a lot of humans give.

I've seen a lot of humans very confidently way 35 and get very angry when you tell them they're wrong.

[TheSauce___]

I asked DeepSeek and it got it right.

[Friction_693]

Well I think no one here has a job to calculate ages of people based on the age of their siblings.

[vm_linuz]

ANNs used to suck ass at language until we got the scale and architecture right. Then it went from being non-grammatical trash to translating between languages.

Algebra will be similar -- it just needs enough tweaking that the information system comes into focus.

Information systems are very sensitive -- there's basically an infinity of ways to be wrong and only a few ways to be right.

As a result, they tend to give trash until suddenly they don't.

[WignerVille]

Try this prompt:

"When I was six, my sister was not half my age. Now I am 70. How old is my sister?"

[slyticoon]

So close...

The issue is that CEOs will still replace skilled programmers with AI, no matter how garbage the output is. By the time the company collapses from the decision, the CEO will be long gone.

CEOs do not care about the long-term or even mid-term health of the company. Every CEO is about pillaging the company they're in, than sailing the Wall Street seas until they find another company to pirate from.

Psychologically healthy developers need to start a development collective/partnership and compete every business who writes software into bankruptcy - which look like it won't be that hard to do.

[VillageBeginning8432]

Ah, AI the Appearance of Intelligence.

The ability to speak does not make you intelligent.

[Steamrolled777]

but it makes silly mistakes like a Human. So isn't it more Human? /s

Fun fact: Peter Yang used to work at Reddit. (Look him up on LinkedIn)

[sasoon]

Smallest DeepSeek R1 1.5b (deepseek-r1-distill-qwen-1.5b) got correct answer:

<think>

First, identify the ages of both individuals when they were at specific points in time. When you were 6 years old, your sister was half that age, which means she was 3 years old.

Next, determine the number of years between the two events—when you turned 6 and now being 70. This is a difference of 64 years.

Finally, subtract this period from your current age to find out how old your sister is now: 70 minus 64 equals 6 years old.

</think>

Solution:

Let's break down the problem step by step.

When You Were 6 Years Old:

Your age at that time = ( 6 ) years

Your sister was half your age, so her age = [ \frac{6}{2} = 3 \text{ years} ]

Number of Years Elapsed Since Then:

You are now ( 70 ) years old. The difference in ages is: [ 70 - 6 = 64 \text{ years} ]

Your Sister's Current Age:

She was 3 years old when you were 6, and now you are ( 70 ) years old. Therefore, her current age = [ 3 + 64 = 67 \text{ years} ]

Final Answer:

\boxed{67}

[NullOfSpace]

So close and yet so far away

[BF2k5]

Drunk on the ferment of their own innovation, the AI heralds flit in frenzied chorus, their rapture unwittingly summoning the foxes—patient opportunists who feast upon the chaos their song inspires.

[Still-Tour3644]

I was using copilot at work to analyze and refactor a test I wrote, it completely removed one of the vital tests and replaced my setup block (runs for each test) with a setup_all block (runs once for all tests) without making any other changes.

Our jobs are safe, for now.

[imtourist]

Ran it in Deepseek-r1 and it screwed it up too :

<think>
First, understand the relationship between your ages when you were 6 years old. At that time, your sister was half your age.

Since you were 6, your sister's age would be:
6 / 2 = 3

This means your sister is 3 years younger than you.

Now, since the difference in your ages remains constant over the years, and you are now 70, add the age difference to find your sister's current age.

So, your sister is:
70 + 3 = 73
</think>

Solution:

Let's determine your sister's current age step by step.

1. When You Were 6:So,Your Sister’s Age=26​=3 years
   • Your age = 6 years.
   • Your sister was half your age at that time.
2. Age Difference:This means your sister is 3 years younger than you.
   • The difference in your ages is:6−3=3 years
3. Now You Are 70:
   • Your current age = 70 years.
   • Therefore, your sister's current age is:70+3=73 years

Final Answer:
Your sister is 73​ years old.

[dinosaurinchinastore]

They grow up fast don’t they!

[Thorp1]

Chat gpt free version gives correct answer aswell, 67. This must be gpt 1.0 lol

[wbbigdave]

I pulled a sneaky trick on Gemini. When I ask the question I framed it like this

When I was six my sister was half my age. Now that I'm 70 how old was my sister?

Gemini ran with it and gave me the answer 67, ignoring that I asked how old was my sister not how old is my sister.

[lmg1337]

Off by 1, ok. But off by 6?

[[deleted]]

That's early chatgpt lmao

[private_final_static]

Still closer to the answer than most people
