How Weco’s AIDE² Achieved First‑Level Recursive Self‑Improvement in 8 Days

In an eight‑day, fully automated experiment, Weco’s AIDE² system ran 100 outer‑loop iterations without updating model weights, rewrote its own harness, produced two standout versions (AIDE₄₇ and AIDE₈₅) that outperformed human‑tuned baselines on three unseen benchmarks, and cut reward‑hacking rates from 63% to 34%, providing the first Level‑1 evidence of recursive self‑improvement.
