OpenRouter usage is likely skewed towards LLMs that are more niche and/or self-hostable by solid hardware that's available, but most consumers don't have on hand. I can imagine Anthropic and OpenAI LLMs often get called directly from their APIs instead.
At least from my experience and friends of mine, we use OpenRouter for cases where we want to use smaller LLMs like Qwen, but when I've used ChatGPT and Claude, I use those APIs directly.
0.1% of OpenRouter is around 400 billion tokens per month or around $400k per month at a cost of $1 per 1 million input tokens, not counting output.
I think it's pretty disingenuous to call your SaaS little when it is projected to spend at least 5 million USD just on tokens and this is a low end estimate.
Their homepage says 30T tokens monthly, so 0.1% would be 30 billion.
And I pay way less than $1 per input token, especially when caching is taken into account.
EDIT: they updated it in the last day or two, now it says 70T, so I’m a little below 0.1% now. But seriously, the point stands, 70T tokens a month just isn’t that much in the global scheme. The big labs are pushing quadrillions each.
