> Are you buying from a provider that isn't listed on open router already

I am using openrouter with zdr guardrail which routes to any provider that supposedly doesnt train on user data. I also use fireworks (directly, not via openrouter) which is a provider promising zdr and has a bunch of open weights models. My issue is that these zdr providers dont transparently disclose caching/tokens etc and so they end up being far more expensive than directly using DS.

Have you tried Novita? They're zdr and I find they usually have better cache hit rates than fireworks. No affiliation.
