Loops may be becoming unnecessary for long-horizon model work
Simon Willison argues that loops were a short-lived workaround for models that could not reliably keep working on a long task until they reached a defined goal.
He says newer systems like Fable and GPT-5.6 — and probably Kimi K3 too — can already do this out of the box, without needing an external loop or orchestration layer.
