Sakana AI Replicates Picbreeder

SakanaAILabs · x · 2026-07-15

Sakana AI published a study replicating the 2008 Picbreeder open-ended evolution experiment using Large Vision-Language Models (VLMs). Their approach involves a "tribute" rebuild of the original website, allowing CPPN images generated by VLMs to be: - Branched out for further evolution - Scored and evaluated - Individually inspected and reviewed This work attempts to explore the components of "open-ended generation/evolution," investigating whether large model agents can recreate an emergent creative process similar to Picbreeder.
