Rishi Desai

I'm currently building RL environments for agentic coding at Abundant AI. Previously I graduated from Stanford with a BS and MS in computer science and minor in music.

My recent work focuses on building tools for creating RL environments, evaluating dataset quality, and studying agent traces.

Check out SWE-gen, a new tool for scaling SWE-bench–style task generation.
