What status quo? Just look at Openrouter's rankings: https://openrouter.ai/rankings

Things change radically month to month. Nobody is remotely close to capturing the market or having any kind of stability over time. People move around quite a lot, often to sidegrade within a generation. Just playing fly on the wall with discourse would be enough to tell you all of this, even without the data to back it up.

That's got a significant selection bias. Claude and ChatGPT and Gemini and other subs do not go through openrouter.
