I’d also say it keeps the frontier shops competitive while costing R&D in the present is beneficial to them in forcing them to make a better and better product especially in value add space.
Finally, particularly for Anthropic, they are going for the more trustworthy shop. Even ali is hosting pay frontier models for service revenue, but if you’re not a Chinese shop, would you really host your production code development workload on a Chinese hosted provider? OpenAI is sketchy enough but even there I have a marginal confidence they aren’t just wholesale mining data for trade secrets - even if they are using it for model training. Anthropic I slightly trust more. Hence the premium. No one really believes at face value a Chinese hosted firm isn’t mass trolling every competitive advantage possible and handing back to the government and other cross competitive firms - even if they aren’t the historical precedent is so well established and known that everyone prices it in.
