Open-endednessendorses
Build AI via open-ended self-generated curricula; safety must follow from the dynamicsArgues evolutionary and open-ended search methods are an underexplored complement to gradient-based learning; co-founded Sakana to pursue them at scale, particularly for model-merging and discovery.
We are using evolutionary algorithms to discover better foundation model architectures by merging existing open-source models. The combinatorial space is vast, and pure scaling overlooks much of it.
