Replit Agent lets AI choose its own sub‑agents, cutting cost and boosting scores

Replit released the Replit Agent, a system where the AI model itself picks sub‑agents, sets their size and effort, and decides when to reuse them. On the DeepSWE benchmark it scored 72 % for $2.11 per task, beating a side‑kick setup by 11 points. The same agent hit 49 % on Terminal‑Bench at $2.53, also ahead of the baseline. The change lets stronger models like GPT‑6 Astra delegate work to cheaper helpers, keeping expensive tokens for the hardest decisions.
