These models don't do any background reasoning (essentially thinking before answering). Definitely recommend trying out o1-mini which does do this. Currently o1-mini does better at maths than o1-preview, but o1-preview has better general knowledge reasoning. o1 when it's finally released should be just downright better than o1-mini at everything including maths. Highly recommend trying some of these out on that model :)

[@Eagle3302PL]

The problem is that chatgpt or any llm, they are not applying formal logic or arithmetic to a problem, instead they regurgitate a solution they tokenized from their training set, and try to morph the solution and the answer in the context of the question being asked. Therefore, just like a cheater, it can often give a correct result confidently because it has memorised that exact question, sometimes it can even substitute values into the result to appear to have calculated it, but in the end it's all smoke and mirrors. It didn't do the math, it didin't think through the problem, that's why llm's crumble when never before seen questions get asked, because an llm has no understanding, only memorisation. Also llms crumble when irrelevant information is fed alongside the question, because the irrelevant information impacts the search space that's being looked at, so accuracy of recall is reduced. LLM's do not think, they do not process information logically, rather they process input and throw out the most likely output, and use some value substitution in the result to appear to be answering your exact question. LLM's cannot do mathematics, at best they can spit out likely solutions to to your questions where similar or those exact questions and their solutions have been fed to them in their training set. An LLM knows everything and understands nothing.

[@CoalOres]

They _might_ process information logically, we actually don't know. Since they generate it word by word (or token by token), after enough training it might have learned some forms of logic because it turns out those are very good at predicting the next token in logical proofs. Logic is useful for many different proofs, just memorizing the answer is only useful for a single one (i.e. it would be trained out pretty quickly); this doesn't guarantee it knows logic, but it makes it plausible. It is a common misconception that these programs work by searching the dataset, 3Blue1Brown has an excellent video series I would recommend that shows just how complex its underlying mechanics actually are.

On an unrelated note, I remember sitting this BMO paper last year and struggling but enjoying it.

This is what I love about maths, how I can always continue with just some practice. P.s, great video Tom, really enjoyed watching it.

Power of a point is actually real and while I’m usually bad in geometry at olympiads, some of my friends used it several times.

[@deinauge7894]

ok. to use this at the point Z you need two lines through Z which cut a circle in 1 or 2 points. Say this circle is centered atB with radius BA. You can conclude: ZX*ZY = ZB*ZW (W is the point where ZB coincides with the circle) Since ZW=ZB-BA we get ZX*ZY = ZB*ZB-ZB*BA. This looks almost like what chatGPT wrote. I'd give it a pass 😂

[@gergoturan4033]

I've only watched up to the first question so far, but I came up with a different solution that's interesting enough to mention. Another way to think of the problem is dividing the characters into 2 subsets, one of them is the characters that were typed 1 late and the other is all the others that weren't. If all the characters are different, these 2 sets give enough information to reconstruct any possible spellings. Therefore, we just need to count all the ways to make these subsets. We know that in an n character long word the last character can never be 1 late. So we only have n-1 letters left to work with. [n-1 choose k] will give us a k sized subset. To get all possible subsets, we need to sum up for every case of k. [sum(k = 0..n-1)(n-1 choose k)] This is the n-1st row of Pascal's triangle. We know that the sum of the n-1st row of it is 2^(n-1). The word "OLYMPIADS" has 9 letters, therefore the answer is 2^8 which is 256.

[@dmytryk7887]

In Q1 there seems to be an error in chatgpt's explanation. For example, it says "D" must be in position 7, 8 or 9 but "DOLYMPIAS" is a valid misspelling...every letter is one late, except for D (early) and S (correct).

[@SgtSupaman]

Yeah, its mistaken assumption that a letter must be within one of its original location (in either direction) actually limits the number of possible permutations to 55. So, it definitely didn't properly pair up its explanation with its answer.

Hey Dr Crawford - thank you for your video and insight. It seems that you are using the basic GPT4 model to solve these BMO questions. There is a different model ChatGPT provides called the o1-preview, which is specifically designed for complex and advanced reasoning and solving difficult mathematical questions like this. If you use the o1-preview model, it would take way longer time (sometimes even more than a minute) before giving you a response, and it thinks in a way deeper way than the model you have used here. With that model, I've tried feeding it questions 5 and 6 on the BMO1 paper, and it could solve them perfectly. Therefore I would encourage you to try again with that specific model. I do believe that you have to have ChatGPT subscription to access that model, but I think that they are going to release a free version of that model. Anyways, thanks you so much! P.S. It would have been better if you simply uploaded a screenshot of the question as diagrams could have been included, and ChatGPT would be able to read the question from the image (probably better than it being retyped with a different syntax)

By using this logic and the fact that any ai and ai-1 are some linear combinations of a0 and a1 it folowsthat gdc(ai,ai-1)=gcd(a0,a1) henceif they are consecutive they both have gcd of 1.

You did not use the latest o1 series of models. I was trying to search for where you mention which model you were using - couldn’t find an exact response and you have cropped the part where it mentions the model and also haven’t shown the footage of the answer generation - which would give away the model you were testing. O1 can not generate images - which was the give away. Do the same tests with o1-preview.

[@uenu7230]

Forgot exactly how I phrased the question to chatgpt, but it involved splitters with 1 input and 1-3 outputs where the outputs were equally divided from the input, and mergers with 1 output and 1-3 inputs where the output is equal to the sum of the inputs and how to construct a sequence of splitters and mergers to end up with two outputs with 80% and 20% of the original source input. It said to split the first input with a 1-2 splitter (50%/50%) and split one of those outputs with a 1-2 splitter (25%/25% of the original input). then merge the remaining 50% with the 25% and that will equal the requested 80% output, and the remaining 25% equals the requested 20%. In summary, it thinks that 50% plus 25% equals 80% and 25% equals 20%. So, yeah, ChatGPT can't math.

On the unreliable typist: I feel ChatGPT mischaracterized the possible positions of letters (or I'm drastically misunderstanding the rules. In steps 1 ^2, it said 'S' can only be in the last 2 positions. But 'SOLYMPIAD' appears to fit the rules ('S' is way early, and each other letter is 1 late). It may have gotten the right answer, but it's argument was flawed. On the polygon: Step 1 is false. Convex with equal sides does *not* imply the vertices lie on a circle. A rhombus is convex and all its sides are equal, but the vertices are *not* on a circle. This alone invalidates all the rest of the proof, which relies on the circle. Also, in step 4 part 'n=5', the 3 diagonals do *not* form an equilateral triangle. Nor would it "ensure … a regular polygon" if they did. The important thing to remember is that LLM "AI" isn't *reasoning* at all. It's just stringing a series of tokens together based on how often it has seen those words strung together before, plus a bit of randomness.

For the unreliable typist problem, the professor failed to notice that ChatGPT cheated in its answer, thus the professor has failed in his duty; he should have spotted the flawed argument. Additionally he should have called out ChatGPT for cheating. ChatGPT failed to provide an acceptable answer. We know that ChatGPT had trained on this question since Tom said that he had presented the same problem to an earlier version. Thus ChatGPT already had stored up the correct numerical answer. However it overtly cheated in the lines between its flawed reasoning and the numerical answer. Look at 3:24. It multiplies two by itself nine times, and then writes that this is equal to 2^8 = 256. Count the twos; there are definitely nine of them. The reasoning was flawed on line 9. Once 8 letters are typed, the last one has only one place to go, not two. Since the question specified "with proof", ChatGPT failed to provide correct reasoning but was able to recall the correct numerical result from its training. Then it cheated to make them fit together. That's bad math.

[@eofirdavid]

ChatGPT's "proof" for the first question was wrong. According to its "step 2" the answer should be 2^2 * 3^7 which is false. Also, the possible position are wrong since the n-th letter can be in any of the 1,...,n+1 position (except for the last letter which is in 1,...,n). I have no idea why it needed to mention Young Tableaux in step 3, since even if they are related somehow, this is a simple problem that doesn't need anything advance in order to solve it. Finally, in step 3, without a proper explanation it suddenly only gives 2 possibilities for each letter, and for some reason the letter 'L' has either 2 or 3 possible positions. Even if you ignore this, and give 2 positions for each letter you get 2^9 and not the 2^8 correct answer.

[@FlavioGaming]

L has 2 possibilities AFTER placing O in position 1 or 2. Y has 2 possibilities AFTER placing the letters O and L in their positions and so on...

[@FlavioGaming]

For the last letter S, it should've said that since we've placed 8 letters in 8 positions, there's only 1 place left for S.

[@eofirdavid]

@@FlavioGaming You are right. Without the knowledge of the position of the previous letters, the n-th letter can be in 1,...,n+1 positions (which seemed what step 2 meant to say) and after you assume that you placed the previous n-1 letters, then you only have 2 possibilities (which should have been step 4), except for the last letter which only has one possibility. In any case, while somehow chatGPT managed to give the final right answer, everything in between seems like guesses. This sort of proof is something which I would expect from a student that saw the answer before the exam, didn't understand it, and tried to rewrite it from memory, which granted, this is how chatGPT works. I would not call this "mathematics", and I have yet to see chatGPT answer any math problem correctly, unless it is very standard and elementary and its the type of question you expect to see in basic math textbooks.

For the second question. case 1 -> ai = 2ai-1 - ai-2 -> Subtract ai-1 from both sides -> ai - ai-1 = ai-1 - ai-2 so di as per chat gpt's suggestion -> di = ai-1 - ai-2. So Now if a2024-a2023 = 1 as they are consecutive. So a2023-a2022 = a2024 - a2023 = 1 -> a2023 - a2022 = 1 -> a2023 = a2022 + 1. And so it follows for the entire series. case 2 -> ai = 2ai-2 - ai-1 -> ai + ai-1 = 2ai-2 -> Now a2024 and a2023 are consecutive. So a2024 + a2023 = 2*a2022 Now two consecutive numbers means one is odd and one is even. So the sum will be odd. That means a2024 + a2023 = 2k+1 So 2k+1 = 2a2022 -> a2022 = k + 1/2. So it is not an integer. But the problem suggests that the sequence is of integers. Hence case 2 is not allowed.

It works with the math needed for engineering but not what we come up with in Physics (theory)-we do rely on concepts freshly come out of pure math and a mathematician’s mind. How about showing chatgpt o1 getting literally tossed in the storm with G(n) 😅 20:05 Yea Sabine and the rest don’t like it too. Mathos is pretty decent compared with o1 but also fails later.

ChatGPT can't draw a simple cardioid. Even after I gave it the formula.

The obvious problem confusing ChatGPT is your use of terms involving letters "a_i" when describing the equations :)

[@Calcprof]

A while back I saw a "research" paper written by CHatGPT about an issue in game theory It was absolute nonsense, the vocabulary and sentence structure was all OK, but the "logical steps" were all outright nonsense.

Hi @TomRocksMaths, will you upload celeberation video of 200k subscribers?

[@TomRocksMaths]

it's coming before the end of the year :)

power of points is a niche set of tricks for olympiads

I tried getting Gemini to draw its 'solution' to 3) and it responde with the link to the solutions XD.

I once asked chatgpt to use my algorithm to find the no of prime numbers from 1 to 173, It said 4086.99

No AI is as good as humans when it comes to Mathematics. AIs failed so many prompts I've given them

[@juanalbertovargasmesen2509]

Power of a point is very much a real theorem. It is involved, for example, in Geometrical Inversion through a circle. ChatGPT completely misapplied it though, and the formula it provided has nothing to do with it.

The newlines might confuse it slightly

[@PrajwalDSouza]

O1? O1 preview?

[@Hankyone]

This oversight makes no sense, is he not aware these models exist???

[@TomRocksMaths]

the plan here was to use the free version as it is what most people will have access to, so I wanted to warn them to be careful when using it.

[@PrajwalDSouza]

@@TomRocksMaths Makes sense. :) However, like I mentioned earlier, given the title of the video, it might be apt to include a discussion on o1 or drawn a comparison with o1. Damn. I sound like a reviewer now. 😅

Khan's Academy explains the "power of a point theorem".

Chatgpt is already smarter than all nine members of the US Supreme Court. But, I tend to doubt that Chatgpt will ever get to the creativity level of any well known mathematician in history. We can breathe a sigh of relief.
