I think it's kind of like what GitHub has despite getting rid of the quota system for Copilot: existing customers that are already setup to deal with them.

In this case I imagine that OpenRouter's moat is going to be that businesses that already use Stripe will have a lower bar to choosing OpenRouter to provide the AI access, and clean integration with Stripe to pay for stuff like AI support bots.

Isn't copilot a cheaper harness than claude code and offers more flexibility?
