That's just it: This is
not happening with the Chinese models, because western corporations are the primary drivers of AI adoption globally and western corporations are not signing up for a DeepSeek API key. If they're working with Chinese models at all, which they rarely are, it is via a western-hosted provider like Bedrock, Vertex, or OpenRouter; or self-hosting. Sure, hobbyists and individual programmers might be comfortable forming a business relationship with a nationalized Chinese entity, but you'd need a microscope to see that relative to the spend that, say, Eli Lilly is throwing at Anthropic every week.
But you're right that OpenRouter is only one data point. It is, unfortunately, one of the few we have.
