I don't really understand the value -add, so far "smart" routing currently produces worse results at higher cost and static routing can be done yourself trivially. Plus the risk of sending the most sensitive data you have to a third party.
I don't think you understand what Openrouter's product is.
Even ignoring routing, it's still very 'nice' to be able to buy almost any model in one place.
Amazing for enterprises, or companies who are letting users choose from a variety of models for ai tools.
