My company gets a bunch of product listings from our clients and we try to group them together (so that if you search for a product name you can see all the retailers who are selling that product). Since there arent reliable UPCs for the kinds of products we work with, we need to generate embeddings (vectors) for the products by their name/brand/category and do a nearest-neighbor search. This problem has many many many "old school" ML solutions to it, and when i was asked to design this system I came up with a few implementations and proposed them.

Instead of doing any of those (we have the infrastructure to do it) we are paying OpenAI for their embeddings APIs. Perhaps openAI is just doing old school ML under the hood but there is definitely an instinct among product managers to reach for shiny tools from shiny companies instead of considering more conservative options

Yeah, I don't want to downplay the reality of companies making bad decisions.

I think for me, the way the GP phrased things just made me want to give them the benefit of the doubt.

Given my experience, people I've worked with, and how the GP phrased things, in my mind it's more likely than not that their not making a naive "chase-the-AI" decision, and that a lot of replies didn't have a whole lot of call center experience.

The department I worked with when I did work in call centers was particularly competent and also pretty org savvy. Decisions were always a mix of pragmatism and optics. I don't think it's hard to find people like that in most companies. I also don't think it's hard to find the opposite.

But yeah, when I say something would be surprising, I don't mean it's impossible. I mean that the GP sounds informed and competent, and if I assume that, it'd be surprising to me if they sacrificed long-term success for an immediate boost by slotting LLMs into something so core to their success metrics.

But, I could be wrong. It's just my hunch, not a quantitative analysis or anything. Feature factory product influence is a real thing, for sure. It's why the _main_ question I ask in interviews is for everyone to describe the relationship between product and eng, so I definitely self-select toward a specific dynamic that probably unduly influences my perspective. I've been places where the balance is hard product, and it sucks working somewhere like that.

But yeah, for deciding if more standard ML techniques are worth replacing with LLMs, I'd ultimately need to see actual numbers from someone concretely comparing the two approaches. I just don't have that context
