I have no problem with the frontier labs releasing their own harnesses. But locking the subscriptions to those harnesses is frustrating. Much like the other tools I use in my job I have a lot of reasons to use my own tooling. I would like to use my own harness with a subscription so it can be more useful to me. I'm sure I'm not the only one. I understand why they don't from a business perspective but it still makes their product less useful to me.

Been using these Gemini models through cursor at work, I think it's API cost for the business. I've been loving these models but you're very right that I won't use them at home or with a better harness than cursor (which is extremely basic) because it's not possible.

Argon and Carbon are available through Github Copilot subscriptions (enterprise)
