Best available does not mean “not actively misleading”, which it obviously is.

OpenRouter is not remotely close to a representative source for inference distribution.

Sure, but the statement you made is way stronger (more general) than the one the data shows.

"Best available public data source" isn't a good reason to insist on using irrelevant data to draw conclusions like "top 5 models by token consumption are Chinese/open models".

another source is opencode and they have geographic breakdown.
