As of May, Google (Gemini) was outputting more tokens in a little under a day than the entirety of openrouter was outputting in a month.
Considering probably 1 out of 1000 LLM users know what openrouter is, I don't know how much weight I'd put into it.
Around the same timeframe, proprietary models dominated this same leaderboard. User preferences shifted.
I would take that number with a huge grain of salt since the useless Google search ai box consumes Gemini tokens.
Intentional Gemini token consumption is likely very very small.
