Tokenmaxxing is over. Routing is the shape.
Chinese-origin AI models now handle nearly half of the enterprise token traffic on OpenRouter in a peak week, up from 4.5% eighteen months ago. That number does not mean the frontier moved to Hangzhou. It means the frontier stopped being the point. The operating pattern of enterprise AI in mid-2026 is a router in front of a portfolio of models, and the router picks the cheapest one that clears the bar. Anthropic and OpenAI still write the ceiling. They just don't write most of the tokens.
