At Warp, we are having fun tweaking our model mix and factory workflow to drive our cost per PR down. It’s gone from $80 → $20 using a factory approach, with a lower revert rate and 40% higher PR throughput than in the last month.

Folks on the team are suggesting experiments to improve further, like reducing subagents and building model routers. As a startup founder who cares deeply about efficiency and burn, seeing us reduce costs while increasing velocity and quality is incredible.
