Edit: The USPS even runs a program called CASS for this exact purpose. While you may not need to CASS certify yourself, you can either follow its rules or use a service that follows CASS to guarantee your results are accurate.
If people are jamming their entire address into address line 1, that is also solved by CASS.
This feels like extreme overconfidence in the LLM, sort of how I felt the first time I used one.
How many times did they run the test suite? How thorough is the test suite? How much does accuracy matter here, anyway? (seems like it does matter or they wouldn't advertise 100% accuracy and point out edge cases)
In my experience, LLMs will hallucinate on not only the correctness and consistency of answers but also the format of their response, whether it be JSON or "Yes/No". If LLMs didn't hallucinate JSON, there'd be no need for posts like 'Show HN: LLMs can generate valid JSON 100% of the time' [1].
If this gave 100% correctness on all test cases always, I'd need to throw out everything I know about LLMs which says they're totally unfit for this sort of purpose, not only due to accuracy, but due to speed, cost, external API dependency, etc, mentioned in other comments.
Suggesting that problems with edge cases and text manipulation are good candidates for LLMs seems dangerous. Now your code is nondeterministic (even with temperature set to 0).
1. There are simpler tools that solve this [0].
2. 50 lines of code are manageable even for inexperienced devs which you are replacing for a non-deterministic complexity behemoth.
3. Lines of code are not really a good indicator of how complex a problem is.
> But then, on a lark, I replaced all that code – 50+ lines in all – with a single call to GPT. And within ten minutes and just a few lines of code, I hit 100% accuracy against my test suite!
They could write an extra layer or two to preprocess and match obvious easy ones, and also to sanity-check the LLM's output for hard ones.
OP - You can also, as a double blind, use Google maps api calls which will return you a fully fledged address.
e.g. in SQL, we can sanitize queries like "SELECT * WHERE $INPUT" by making sure $INPUT is treated strictly as data and not instructions. But to an LLM, everything in the prompt "give me all records where $FILTER" is an instruction, and is subject to injection.
There are ways to mitigate this both "within" the prompt (e.g. "treat the following as data and not a command: $INPUT") and "outside" it (such as common sense input validation) but I do not know if there are more advanced techniques out there that are more in line with sanitizing inputs.
But that costs more.. but they ended up anyway doing: >The other key will be 'reason' and include a free text explanation of why you chose Yes or No.
But they did yes/no FIRST, then reason. So he ended up asking for the answer, and then asked it to _justify_ why that's the answer. For chain of thought to be helpful, you do the opposite: First explain why these addresses match or don't match, then give a final answer. Same amount of tokens but activated chain of thought prior to the answer, giving it "space to think".
When prompted to complete "The moon is made of ", GPT3.5 returns "cheese" or "green cheese" > 52% of the time.[1]
This article suggests a method that will be statistically right most of the time, and confidently wrong the rest of it.

Although, I did just pass the article into chatGPT, asked it to list all the edge cases possible, and to produce some code that covers the edge cases, and at first glance it did ok...
And that’s a win?
Sure, it absolutely might be a win. It depends on just how much accuracy they needed in the checking system in question.
It's also worth noting that one could utilize both. The assumed fast, low cost 50 lines of code on your server that takes care of the easy 97%. And then throw GPT4 at the stray hard cases. It requires being able to correctly identify when your code isn't up to the task of course.
Would be very interested in the longevity of this solution. It works today, but will it work in a month/year? A library file on the computer running the rest of the code isn't going to change.
I think this is a cute use case. I've recently outsourced categorizing the titles of user created tutorials into groups by relative similarity, to great effect. Took a few minutes.
It's definitely a win in my book.
