#32Am I the only one that thinks this is a huge waste of resources?
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.

#33I'm a bit skeptical of the 100% success rate against the tests, when it turns out that to go from 90% to 100%, you had to list a bunch of examples in the prompt that I bet are right from your test suite...

#34I can't help but think LLM is the wrong tool for the job here. There are many address validation and standardization services, including databases you can get straight from USPS. Those services will give you real and consistent answers, rather than unknown edge cases that will shift subtly over time as your LLM changes. Edit: The USPS even runs a program called CASS for this exact purpose. While you may not need to C…
This is a classic XY problem [1]. My _immediate_ reaction to seeing the dev attempt to compare US addresses was “where’s the USPS library?” Using an LLM prompt instead of a vetted library is just the wrong answer to solving the right problem.
Re: I replaced 50 lines of code with a single LLM prompt
#35Many comments are criticizing the usage of LLM for this use case but I do believe this will become more common in the future. For example, OpenAI's retrieval plugin leverages LLM to do PII detection [1] instead of using the traditional libraries [2]. [1] https://github.com/openai/chatgpt-retrieval-plugin/blob/main... [2] https://github.com/topics/pii-detection
For this specific problem, I trust the large number of companies that have product lines with devoted test suites more than I do a random LLM. Sometimes it’s better to pick the correct specific tool for a job than a random general purpose tool.

Likely not? It doesn't seem that there's a strict boundary between instructions and data in LLM prompts.
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.

It's a good point, but the challenge is we sometimes just get street1 from a utility without city/state/postal. We tried USPS and geocoding libraries, but they fail because they often pick a random-ish city which likely will not match.

#38Earlier quoted context omitted.
Correct me if I'm wrong, you can pick which dated GPT API to utilize and expect that to not act as a continually changing black box. I've been using the API for a long time and have been able to pick the version. So for example: gpt-4-0314, or gpt-3.5-turbo-0613, etc. The latency issue is definitely true. Ideally the cost could be limited to a very small percentage of hard cases (which you first have to identify).
LLMs don't seem to be deterministic [0, 1, 2, 3]. So no, pinning the version wouldn't be enough.

> So no, pinning the version wouldn't be enough.
You can to an extent dictate GPT's determinism with settings you can pass along in the API, combined with the parent already proclaiming they saw a 100% success rate.
So how do you know it wouldn't be enough? The parent is already saying their test suite indicates it is enough. What tests have you run counter to their claim to show it fails? And how do you know the parent can't increase the determinism even further beyond what they were already using in their testing (and decreasing the risk of negative outcomes by doing so)?

How would a llm know the town any better then the other alternatives?

I would say sometimes data needs to be rejected as invalid. I don't know the exact scenario here, but you'll never be able to know if a street number/name alone is unique as almost any street will have dozens or more matches across the country.
If people are jamming their entire address into address line 1, that is also solved by CASS.
