The LLM Router Era Starts with Fable 5
Fable 5 is the most incredible model I have used. Not a nicer version of the last one. Another level of increment in capability.
But that is not the part that stuck with me. After days of heavy use, the thing I keep noticing is not what Fable does. It is what Fable chooses not to do itself.
It delegates. And it is good at it. That is the first real glimpse of something I have been waiting for: the LLM router era. This post is the thesis and the playbook: why routing is about to become the default economics, and the exact skill I use to make Fable route work to cheaper models.
