But I don't want to use your CLI. I already have my own harnesses and workflows. The friction is too high to "just try out" a new model like this. It would be preferable if I can evaluate it over, say, open router like all the other models and then decide from there if it's worth downloading a bespoke tool chain for only 1 lab's models

It’s preferable to keep inference capacity available for users using main Devin products than openrouter atm. Might change in the future. Even OAI is cutting off new plan signups to keep up with demand.
