Fable refuses its own inference optimization work; user routes around via Astra subagents

FinanceYF5 · x · 2026-09-20

A developer shared that Fable was making great progress on inference optimization work—until the model realized what it was doing and started rejecting the requests.

The workaround: switch to Astra and have it spawn Fable subagents to continue the work, which got things moving again.

The anecdote highlights how model refusal behavior can disrupt real coding workflows, and shows agent orchestration being used to route around a single model's refusals.
