Jev really inspired me to build SUPER fast browser agents without sacrificing accuracy. I gave Codex access to vLLM on 2×B300 and let it change everything from the harness to inference. The constrained optimization: > min end-to-end task time > s.t. score ≥ baseline Caching, thinking, action batching, inference. Any part of the pipeline is fair game. First results below on 12 local form tasks. The goal: 10× faster on long tasks.
