Correct me if I'm wrong, but OpenRouter doesn't tell the whole story.

If I'm using OpenAI, Anthropic, or Google models, I'm probably using their API directly, so OpenRouter won't have those stats to compare to.

All that said, it is very exciting to see open model usage grow via OpenRouter.

It doesn’t show the whole market of course, but the trend lines are interesting

Definitely interesting seeing it grow there. I'm now curious to see if it's overall market usage growing for LLMs (with more OpenAI and Anthopic usage in a similar growth rate), or if it's more heavily weighted towards open models specifically.

With the price to performance of the latest open models, I think most cases for integration into applications would get a best bang for the buck from an open model.

Yes, but there may be other events that are correlated.

For example, they changed their fee structure in June. It is possible that users of closed models moved from OpenRouter to directly using OpenAI/Anthropic/Google (or maybe Amazon Bedrock), while users of open models are happy with OpenRouter as direct providers can sometimes be unstable.
