Teknium: Fable orchestrated 1390 subagents over 19 hours in one session

Teknium · x · 2026-09-07

Responding to claims that agent failures are a harness and prompting issue, Teknium says Fable handles orchestration fine: it reviews all subagent trajectories and suggests harness improvements, and recently ran 1390 subagents over 19 hours in a single session. Context: the community-found combo of Fable as orchestrator with Astra as implementation subagents works so well that even Astra recommended switching to Fable after its own orchestration attempts failed.
