Fast Cursor agents on simon-says-fast
IDE-integrated agents need sub-second first tokens. We benchmarked routing paths that keep coding loops responsive in Cursor and Ainslie.
Coding agents fail when the first token takes too long — developers context-switch and trust drops. We built a fast path through simon-says-fast that prioritizes latency for short, tool-heavy turns typical of IDE integrations.
The lab compared direct provider routes, orchestrator overhead, and cached system prompts on Einstein hardware. Winners land behind stable slugs so Cursor, Ainslie, and customer apps pick up improvements without changing integration code.
This work sits alongside Tiger Mode for long-running automations: fast slugs for interactive loops, orchestrators for multi-step jobs, both callable through the same Simon API.
