Or maybe Codex/Claude Code got better and more people are just using those?

Or more people are using harnesses that do what openrouter does so they don't need it anymore?

Or they are using other GPU providers directly to run their open source models?

I don't think this data is conclusive. It's a very unique subset who are using openrouter.

Anthropic’s revenue growth has leveled off, too. Not the exponential hockey stick that was predicted.
