OpenCode Founder Calls Out Misleading Open-Source Router Stats

Dax, founder of the coding tool OpenCode (@thdxr), argued in a September 20 post that router data showing open-source models overtaking frontier models is "complete nonsense," even though he says few companies are more oriented around open-source models than his. A model router is a service that sends AI requests to many providers, so it sees only a slice of overall traffic.

He gives two reasons. Most routers see so little traffic that they share only percentages, never real numbers, which can make them look bigger than they are. And no router has a real reason to see 99% of frontier traffic, so what one router observes is not a view of all usage. He adds that they are trying to capture mindshare. This is his opinion, not an audited finding, and he names no company or report.
