New UC Berkeley paper shows that a supervisor that keeps reorganizing a team of coding agents can beat expert GPU kernels where single agents stall.
Coding agents make fast early progress on GPU kernels, then settle on easier designs and plateau far below expert code. On the MLA decode kernel, Claude Code stalled at 0.51 times FlashInfer's speed.
Evolving Agent Teams adds a supervisor that diagnoses each plateau and rebuilds the team, inventing roles like a profiler, a debugger, or a knowledge integrator. A shared file system keeps lessons from every past team.
Under the same token budget it reached 0.74 times FlashInfer on MLA decode, against 0.31 for a fixed 4-role team. With more budget it hit 1.21 times FlashInfer's speed, winning on 36 of 47 production workloads.
For long, hard optimization runs, have a supervisor restructure agent roles when progress stalls instead of running 1 fixed agent setup.
