Free the models: Harness design at the frontier (Replit)
blog post · Story page
Replit Agent's core loop now picks its subagents' tier and effort and adjusts its own as the task unfolds, instead of a router out front. Replit reports it beating a sidekick setup, one long-lived worker, by 11 points on DeepSWE and 16 on Terminal-Bench.
In plain words
- Replit's coding assistant now decides how to share work with other automated helpers.

- It adjusts how much effort it and its helpers spend as the task develops.
- Replit reports that sharing work this way improved its coding assistant's test scores compared with keeping the same helper throughout.
