> shouldn't your willingness to pay/not pay be a function of your experience and the value the product delivers you, rather than an implementation detail such as fine tuning vs prompt engineering?

bullshitting/lying isn’t implementation detail, it’s a mindset and I understand people who actively try to avoid it. Prompts and rag don’t make it a new powerful model that is superior to say ChatGPT

Yeah, that's basically what I was thinking. I didn't wanna use the word "lying" as to not appear super confrontational, but when someone claims it's using a model called "langcss.fast", it should be safe to assume that they're actually using a custom model. It's disingenuous at best.

I'm not even saying there is any need for a custom model. Obviously, RAG etc. can work just as well, or even just a well-crafted prompt on a foundation model. But selling it as a custom model is misleading on purpose, and deters me from using the product.
