Right, that chart shows App usage based on the user-agent header but doesn't tell you if there is a single individual user of an app that skews the results.
I was skewing the Gemini starts with my Aider usage. Basically the only model in using with openrouter, until I recently started running qwen3-next locally.
2.5 is probably the best balance for tools like Aider.
A "weekly active API Keys" faceted by models/app would be a useful data point to measure real-world popularity though.
