@KuJoe I'd be very skeptical of such claims of results.
I'm reminded of the hype around blockchain tech, which in B2B was accompanied by a lot of claims about savings and efficiency gains as well, but then when you looked closer it was usually a subtle but total misrepresentation of what actually happened, and in the end none of it actually worked as people claimed.
My bet on the 'savings' here are that either a) this wasn't actually LLMs or the current generation of "AI" and rather older, more specialized systems, b) it *was* the current-gen stuff but with so much manual guidance that it was ultimately still just humans doing the work, or c) the measurement itself was selected to show positive outcomes, regardless of real-world effects.
(B2B claims are usually only looked at by people on the management layer and not by the subject matter experts, so if you sound confident enough you can pretty much just claim whatever you want, it doesn't need to stand up to scrutiny)
