Experimental evidence of recursive self-improvement
Potentially notable if the evidence holds up, because it frames RSI less as dramatic self-rewriting and more as automated harness optimization that outperforms long human iteration.

What it is: Zhengyao Jiang claiming the first experimental evidence of recursive self-improvement in an autoresearch agent
Gist: The specific claim is not generic "agents got better with more tuning," but that an agent spent eight days autoresearching its own harness and produced a variant that beat a hand-tuned baseline built over two years on held-out benchmarks. If the thread substantiates it, the interesting part is not self-modification in the abstract but search over agent workflows yielding benchmark gains that transfer beyond the optimization loop.
Newsletter angle: Potentially notable if the evidence holds up, because it frames RSI less as dramatic self-rewriting and more as automated harness optimization that outperforms long human iteration.
