DuoDiscover: Scaling Autonomous Discovery Beyond the Evaluation Bottleneck. Arxiv 2026.
DuoDiscover lets coding agents co-discover an optimization target and a fast, fidelity-checked proxy evaluator, so search is no longer bottlenecked by hours-long true evaluations. It ranks first on 121 of 235 kernels on NVIDIA’s SOL-Exec B200 leaderboard, doubles human-expert speedups on SWE-fficiency, and reaches 1.92× on vLLM serving. Work done at Google.
