Was there a use-case where you deployed Fable where you couldn’t use Opus in a non-interactive case? Perhaps Sonnet 5 will fill the gap because it’s better in agentic loops.

It’s so expensive, though. Useful interactively in coding agent but boy if you have a kind of task that Fable can do in an agentic loop that Opus can’t then you’re in a good place. Doubtless the frontier will move forward. These kinds of “problems of the future” are great to have solutions for.

And for an interactive agentic loop, not using Fable is just missing out on something. There’s no lock-in there.
