Seriously: I roll my own harness over OpenRouter and GPT 5.6, and it is genuinely better than CC+Fable for my maths and programming use cases.

The one thing Fable 5.1 still tops out on is the ability to take a simple "Let's engage in an interactive complexity-removing session" and materialize abstractions and semantics quickly.

I believe you can use an OpenCode Go sub with any tool, was stated as such last time I looked at their docs.
