I dont know why people use openrouter ,instead of a monthly subscription, if they can. While i am barely able to use up my 100$ monthly subscription, i can easily spend 10$ a day on openrouter (200-300$/month). Using top-tier models on openrouter is so much more expensive from my experience then any subscription.
I'm using Deepseek flash for certain tasks, it is pretty hard to spend $10 on it. All their top models (by usage) are not from frontier labs.
I agree but subscriptions have limits, openrouter's very handy for excess.
All are moving from monthly to usage payments anyway.
You use the model you need. You don't need to use always the top tier model for anything. That is your decision. You can use a top tier for planing and then the agents can use cheap Chinese models. Much more cost effective.
