Google publishes Dream RSI paper: agents must dream to recursively self-improve

Google, Google DeepMind, and university collaborators released "Dream-RSI: Recursive Self-Improvement through Evolving Worlds" with an open repo (code in preparation, 485 stars).
- Core claim: the bottleneck of recursive self-improvement is exploration — as targets get harder, discovery stretches over thousands of proposal–evaluation cycles, and poor exploration wastes compute on dead-end directions.
- Fixed strategies can't adapt as search spaces scale, while optimizing the policy online means navigating a vast meta-search space. Dream-RSI tackles this dilemma by letting the agent dream in evolving worlds built from history before improving itself.
- Paper PDF and project page (dream-rsi.com) are live; authors include Tong Zheng, Xidong Wu, and Wang-Cheng Kang.
