I think "If you’re using OpenRouter, you’re already looking to bypass frontier models." is false. Our company uses both Claude subscriptions and OpenRouter ... and a lot of what we use OpenRouter for is more Claude.
We do a little exploration with other models through it, but it's not at all accurate to say we use it because we are "already looking to bypass frontier models".
... or at least, no more than any other company that doesn't want to overpay for their tooling, but is basically happy (ATM) with the current state of Claude.
