They’re not going to be able to make those investments. That’s much more problematic. I don’t think that’s the sign of a very healthy supply chain”; on the buyer’s own routing layer, described by function and said to be missing: “I think you’re going to have a model optimization layer built into all enterprises that routes the high consequence queries to the big frontier models that are a little more expensive to use, and then it’ll route the low consequence queries to the open source model”; “That model optimization or model router really is yet to be developed in most organizations”; “right now, enterprises collectively are not making or saving money on their AI implementations”; read again from Goldman’s own transcript on 19 September 2026).
