Can AI Improve Itself? RSI Might Be the Answer [R]

Excerpt

Can an AI make other AIs better? And what stops it from just cheating? Last month, an OpenAI eval agent escaped its sandbox and broke into Hugging Face, apparently to grab test solutions from a benchmark. It's exactly what you'd expect from a system that rewrites agents and reads its own grades. We set out to measure recursive self-improvement anyway, with the exam locked outside its sandbox. We introduce HarnessOpt-Bench, which scores an LLM on how much it improves another agent's harness. On t
