Most people judge AI models by what they can do today. @rahulgs judges the slope. When we started Ramp, people had tasted better software at home and could no longer tolerate the tools they were handed at work. So we built something better. Same thing is happening now with AI. Our customers use these models every day. They know what speed and intelligence feel like — and anything that makes them repeat themselves or wait for an answer feels broken. Rahul builds for that. Not for the best model today, but for where models will be in 3–6 months. Studying traces. Improving the harness. Cutting CI time. Giving agents real work with real guardrails. He gets into all of it with @bcherny, @Anthropic's Head of Claude Code, and our staff engineer @austospumanto.
