The router sounds kind of like an exciting feature. I've actually gotten into the habit of using Gemini 2.5 Pro for some things and plugging other things into ChatGPT because I don't have access to thinking so I know it will be fast. Having a router that can intelligently figure out when my query requires more thought would be really valuable. I'm still probably going to want a "no really, throw this at the super-duper frontier model" button but I would probably use it less.
