About this video

Software factories at Warp: founder and CEO Zach Lloyd walks swyx through the system his team uses to turn tasks into pull requests, measure agent quality, and improve the workflow itself. The demo follows a request from Slack to a PR, then explores shared agent traces, cost and throughput scoring, and benchmarks built from real engineering work. Zach reports that tuning models and subagent use brought Warp’s internal cost from about $80 per PR to roughly $15–20, alongside higher throughput. How do software factories change the work of product engineers? What belongs in a benchmark? And how
