Q: What does a product manager do?

GPT4: Collaborating with engineering, sales, marketing, finance, external partners, suppliers and customers to ensure …… etc

GPT5: I don't know.

Upon speaking these words, AI was enlightened.



That is genuinely nice to see. What are you using for the embeddings?


We use text-embedding-3-large, with both quantization and MRL reduction, plus oversampling on the search to compensate for the compression.


This is huge news if we finally have a model that is able to say "I don't know".


If a model doesn't "know" what a PM is then I worry about any of its other outputs. That should be dictionary lookup.


Why? It's honest as it doesn't understand it without more context. Lookup could lead to wrong results


Seriously. I have never seen this, even once. I had been wondering if it was impossible. If a model can really say “I don’t know” when it doesn’t know, that could change everything. How many pointless, dumb rabbit holes could be avoided?


My comment peers are really whooshing hard on this. Clearly they have worked with a different sort of PM than I ever have.

The correct answer is: “professional managerial class grift”
