Horace He(@cHHillee):If you look at the actual share of input/output tokens though, it's ~6:1. Perhaps openrouter is assuming a far lower cache hit ratio than is true in practice. Either way, it's an interesting case of the router dynamics distorting the natural pricing for the inference providers! I apologize to companies currently exploiting this if I'm giving away valuable alpha :^) (5/5)
