Use this to add AI to your product to appease management.

Next week, “refactor” it out and brag to manager about cost savings and performance boosts, don’t mention “removing the AI”.

lrvick2• 1 year ago

NPM packages can never be removed once added to a codebase. You can only add more.

mrits3• 1 year ago

This works great for situations where you can’t trust traditional intelligence. Thank you for your contribution

jeron• 1 year ago

why stop there? let's get an is-true-ai that checks if a boolean is true using AI

jsheard• 1 year ago

@grok is this truthy?

VladVladikoff• 1 year ago

False

atum47• 1 year ago

I remember when the whole isEven package was ridiculed for the first time a while ago, back then I thought about training a NN to predict the odds of a number being even, as a joke. I don't actually remember if I actually wrote code for it, but in the end I thought no one would laugh and gave up

ksherlock• 1 year ago

When I watched Andrej Karpathy's NN videos a year or two back, I trained a Neural Network to multiply an integer by two. This was with a rather small training set but if you rounded the results (which was a floating point), they were mostly correct. For positive numbers. My training data didn't include any negative numbers so they were hilariously bad.

sodra9000• 1 year ago

This package should be updated to use the newer gpt-4o-mini model, rather than gpt-3.5-turbo.

Its 3x cheaper, twice as fast, and supports cached input just in case you need to double check if the last number you entered was even. It also has a knowledge cutoff of September 30 2023, which helps for any newly discovered even numbers since gpt-3.5s launch!

vunderba• 1 year ago

Perhaps I should file an issue to increase the accuracy by including a RAG database in LanceDB with embeddings for the set of even numbers up to 32-bits.

elif• 1 year ago

Feeding that into your prompt will increase the token costs

ukuina• 1 year ago

This doesn't work if I use a reasoning model like o3, which does not allow setting max_tokens.

Without reasoning, how can I be SURE a number is even?

hartator• 1 year ago

Multiple models?

parpfish2• 1 year ago

I think before you would deploy this to prod, you should wrap it with a few guardrails to make sure it’s not hallucinating. Pretty simple — just take the output from the llm and see if it agrees with a simple mod2 operation.

Of it agrees, return model output to the user. Otherwise do a couple of retries with different prompts.

mrheosuper• 1 year ago

mod2 is outdated and has not been updated for years, nobody uses it anymore

s1mplicissimus3• 1 year ago

This package has saved me so many hours of tedious gruntwork. It's like a junior developer - you still have to manually check their work, but when it's correct, it's a great productivity improvement.

And don't forget where this will go in a couple years with improved models and more computing power, it's gonna be awesome!

pro tip: play around with the temperature especially when using big numbers as input

hzambo• 1 year ago

Wow, amazing tip. This hack improved my workflow by 10x.

koakuma-chan3• 1 year ago

Are there actually still Junior Developers out there? I thought no one is hiring Junior Developers.

ArthurStacks8• 1 year ago

Its actually the opposite of how people think.

We hire junior devs, but not senior, and dont replace our senior devs. So our developer base is moving towards being junior weighted with less senior. The reason being a junior dev is cheaper, complains less, is more capable now through utilising generative AI, works harder to impress knowing they arent in a safe position, and we can let them go more easily with less process and less reasons needed to be given.

sho_hn2• 1 year ago

Developers who aren't using it are already falling behind.

SamBam2• 1 year ago

Remember, it's not that AI that will take your job, it's the developers who need an AI to tell them if a number is even that will take your job.

1k• 1 year ago

This exactly. It is more important to move fast. Screw the edge cases. As long as it’s correct _most_ of the time, you can always fix anything that’s broken tomorrow.

pavel_lishin• 1 year ago

It's called "eventual consistency".

whatever1• 1 year ago

Why on earth did the software engineering interviews were checking candidates’ ability to think about edge cases? Clearly management does not care.

echelon2• 1 year ago

You laugh now, but our jobs are going to be toast in 10 years.

I thought self-driving would never happen, and now it's here.

margalabargala• 1 year ago

Almost here. Elon said Full Self Driving would mean full self driving within a year! That means we are less than 12 months away from not needing to drove ourselves anymore.

adzm• 1 year ago

Honestly this should take string input as well. Finally I could find out if a Unicode duck or the word "syzygy" are even!

jasonjmcghee• 1 year ago

You might be able to optimize this by using embeddings. Store all the numbers and search "odd" and "even" until you find your number.

asidiali• 1 year ago

This hit way too close to home, I’m cackling.

snorkel• 1 year ago

Lacks an isVeryEven() method, otherwise looks feature complete.

agentdax5• 1 year ago

I’m waiting for them to add the isEvenSteven() method. Then I can integrate this with my escrow smart contract.

crazysim2• 1 year ago

How reliable is this? I'm half joking too but I wouldn't mind reading a report comparing this on OpenAI and various other LLMs.

Somehow I doubt it'll be 100%... right?

geor9e• 1 year ago

normally llms are pretty bad at math, but in this case it should just look at the final digit and map 10 values which I can't imagine going wrong

crazysim2• 1 year ago

I'm just curious how _low_ can you go before it does go wrong.

daemonologist• 1 year ago

The tokenizer might lump the last digit together with some preceding digits though. I know o200k_base (OpenAI -o models) tends to give groups of three (900001 for example is 900-001).

Anyway, I wouldn't be surprised if a non-finetuned model made some mistakes.

timewizard• 1 year ago

is 0x2a even?

gruez• 1 year ago

I tried with this on chatgpt.com (anonymous) and it was wrong:

You are an AI assistant designed to answer questions about numbers. You will only answer with only the word true or false.
Is 393330370227914821469106615363204944758938252979261537157082994586230072180858944545028761701928694832864623009988147774229437650643225379825905427239525512110359581021414640894111281701792224552922491447051506246553646282117414112976459608594044929244664050172002138933343230226871897567 an even number?

response:

True

The prompt was the same used as the library: https://github.com/Calvin-LL/is-even-ai/blob/b00dbfcbb89a197...

est• 1 year ago

its as accurate as how Tiktokenizer deal with numeral characters

nop_slide• 1 year ago

Might be more reliable to ask it to generate a JS function to compute is-even, then just js eval the returned code with the args.

What could go wrong

jameslk• 1 year ago

60% of the time, it works every time

joshdavham• 1 year ago

I’m glad you included an isOdd() method. I was about to ask how you’d check for that.

daft_pink• 1 year ago

Venture capitalist here… how can I invest?

bigbuppo3• 1 year ago

Finally, a reason to use AI.

iamthemonster2• 1 year ago

This is pretty useless to be honest. It's good for telling whether a number is even, but in our industry we need more powerful functionality. We also need to know whether a number is odd.

avandekleut• 1 year ago

Someone should implement this using tool calls.

charles_f• 1 year ago

RTFM, it's not only implementing isOdd but also a large set of rarely used advance operations such as isEqual, or isGreaterThan

Trully AI is astonishing

YokoZar• 1 year ago

Great news! The package includes an isOdd function as well!

nbittich3• 1 year ago

isn't it breaking the one package one responsibility principle?uncle bob wouldn't be happy, it doesn't seem clean

whynotmaybe2• 1 year ago

Why a specific function ?

With a few lines of code, you can just create a list with all the numbers that are even and when you need to check if a number is odd, you simply have to check if it's in the list.

sureIy• 1 year ago

Do we have enough spaces in the ALL_NUMBERS array or do we want to group them by thousands?

ALL_NUMBERS_00001

ALL_NUMBERS_00002

iamthemonster2• 1 year ago

we fired all our junior devs so we can't write code any more

turnsout2• 1 year ago

Yes, this is what we do as a RAG workflow. We created a list of all 32bit unsigned integers and whether they were even or odd, and we pass that into the context. The future is amazing!

crubier• 1 year ago

You can achieve this super simply this by prompting the OpenAI API to call this tool and reverse the output.

SamBam2• 1 year ago

I tried that, but I kept getting "eurt" and "eslaf" and I'm not sure what to do with those. Do I need to send it back to the AI?

Cerium• 1 year ago

Simply add one to the number and then test it again.

briansm• 1 year ago

"This is pretty useless to be honest."

I remember saying that about Bitcoin 15 years ago.

ashton314• 1 year ago

…but there’s only one dependency!! This goes against the NPM ethos of importing anything and everything that you might be tempted to just handle yourself. I’ll be waiting for the Enterprise Version that uses the appropriate number of dependencies.

yalogin• 1 year ago

On a similar note, I was testing LLM's code writing ability and asked Qwen to write me a model to reverse a numerical string. It gave me code and instructions to compile and run. However it had errors in it and after few attempts asking it to fix it, I was able to compile and run. But, alas, the code just kept failing and generated hubris. I gave up. Not to pick on Qwen. I actually like it much better than chatGPT. I have seen Qwen give correct responses when chatGPT lied and gave me wrong information for the exact same question.

lrvick2• 1 year ago

The sad reality is every large production NPM codebase will rely on this within 5 years, just like is-even.

cobbzilla• 1 year ago

This still does actual work. Where are echo-ai and cat-ai?

alexitosrv• 1 year ago

This is the best chain of comments in a HN thread in a long time. Happy to see the hacker spirit strong!

kevinventullo• 1 year ago

This is never going to scale. Eventually we’re going to run out of numbers which have been manually checked for evenness by a human, and instead the training data for the checks will be polluted by numbers which have only been verified by computers.

jwillp• 1 year ago

Training computers on human stupidity has got to be infinitely scalable, by induction.

lucaspfeifer• 1 year ago

Great, now can you make an AI-powered type checker? I wish to expel those pesky types, which too often seem to exist only to clutter my otherwise pristine code. :)

tetrisgm• 1 year ago

Does it also check types to make sure I typed 5 as an int and not a string? Hopefully the ai can solve that

spacechild1• 1 year ago

When do we get the AI powered upgrade of https://github.com/mitsuhiko/is-jonschlinkert?

It would be great if it could also save results to a blockchain. Immutability. IYKYK.

With a layer of smart contracts, dApp on top, this thing could be mooning. When Lambo? In days.

f(): To test if n is even return the value of f(n-2). Special cases for zero and one. Recursion for the win.

azhenley• 1 year ago

You should try Mirror. The LLM-powered programming-by-example programming language I made:

signature is_even(x: number) -> bool

example is_even(0) -> true

example is_even(1) -> false

example is_even(222) -> true

example is_even(-99) -> false

It will take your examples and "compile" to a callable function. You can read more or try it out: https://austinhenley.com/blog/mirrorlang.html

I don't understand why everyone is making fun of this. This is how math is seriously going to be done soon enough.

No, it seriously won't.

LLM's are useless for math, they can't into rigorous proofs.

Those are fake. Overfitting on the test set.

downboots2• 1 year ago

3.14 is even

Loocid• 1 year ago

-2 isn't even?

willmarquis• 1 year ago

Finally, someone had the courage to disrupt the tyranny of the modulo operator. Who needs n % 2 === 0 when you can invoke a large language model and incur network latency, token limits, and API costs to answer the age-old question: is this number even? Truly, we’re living in the future.

riwsky• 1 year ago

I can't even.

…Until now.

downboots2• 1 year ago

Is this program even? Something about it feels very odd.

Sorry for the offtopic post, but I am looking to hire someone with 10 years of experience with is-even-ai. Urgent. Your first unpaid assignment will be to help load balance a bunch of MCP servers to add and THEN check if it's even. So much to go from here! We're a single threaded GPU first identity operator company with a lot history of returning the same thing. We're now expanding to combine and add multiple things. In 6 months of SOTA fine tuning we can already add upto 3 numbers. An MCP first. With temperature 1 we even add random numbers. An industry first. And we're just getting started. Join us. We're adding to our team!

66yatman• 1 year ago

This is a joke right?

aubanel2• 1 year ago

Certainly not, it's actually possible to add 3 float32 numbers with 90% precision using AI! With a recent breakthrough, the team is working on pushing that to 10, we have enough cracked engineers to hope to make it happen soon!

tasuki• 1 year ago

If I were a hiring manager and saw your comment, I wouldn't hire you. Could it have been a joke in a more obvious way? Do you think all the other comments here are serious?

First we invented fire. Then along came the wheel. Countless inventions followed. Today, using the most brilliant minds of our time, the technology of billionaires, and hubris that runs thickly through our veins.. we made not just another step. We leapt head on into uncertain future. It feels odd. Are we even there?

mmustapic• 1 year ago

This is so stupid, we know LLMs are not good enough for deterministic calculations. Just by running it I sometimes get that 31232198731 is even.

This is why I rolled out my own version that uses my own MCP server to call bc.

thiht2• 1 year ago

I have a few qualms with this library:

1. For an AI engineer, you can already build such a system yourself quite trivially by fine-tuning a lightweight inference model, deploying it behind a FastAPI endpoint, and orchestrating requests with a custom prompt pipeline. If you want to go further, you could even ensemble multiple LLMs for higher evenness accuracy.

2. It doesn't actually replace the modulo operator. Most people I know just use `n % 2 === 0` to check if a number is even, and they still keep that knowledge handy in case the AI service is down. This does not solve the reliability issue.

3. It does not seem very "viral" or income-generating. I know this is premature at this point, but without charging users for the library, is it reasonable to expect to make money off of this?

nbittich3• 1 year ago

I don't think you can do 1. without distilling & quantization

the_af• 1 year ago

Where I work, they are laying off all even parity engineers, to be replaced with this. They are keeping the odd parity engineers.

This will achieve their goal of replacing half the staff with AI... at least I think so, I should check with is-half-ai.

jgalt212• 1 year ago

The other joke package is-even has 179K weekly downloads. Is an LLM making up these numbers as well, or is this the Dead Internet at work? And if it's the Dead Internet, has the Dead Internet ever heard of caching? Maybe the Dead Internet gets a kickback from S3 egress fees.

https://www.npmjs.com/package/is-even

moritzwarhier• 1 year ago

I don't think this isEven AI.

It's a remote server running assembler, C and and CGI code, it sends your OpenAI key to the Super Intelligence to make paperclips and reaps the benefit of all the productivity increase by AI for the creator.

Who of course is made from paperclips.

jsomedon• 1 year ago

uh.. Are these comments in this thread even serious? Because they surely feel odd to read.
