Harness Engineering and the Path to RSI
AI寒武纪 · wechat · 2026-07-08
The post summarizes Lillian Weng's deep dive on "Recursive Self-Improvement (RSI)." The core takeaway is that a more realistic near-term path isn't directly rewriting model weights, but optimizing the execution system surrounding the model, known as the harness. The harness—responsible for planning, tool calling, context management, and result evaluation—is deemed just as critical as the model itself.
