Sakana AI builds evidence checks into its open-source AI scientist
David Ha's third-generation research system assigns coding agents parallel experiments, baselines and ablations, while researchers remain responsible for judging the results.

Why it matters
Sakana is treating evidence checks and human review as core components of an AI research agent. Its early results show what the workflow can automate, while the mis-scored candidate exposes why the scientific judgment still cannot be handed off.
Sakana AI has released The Agentic Scientist, a third-generation system that coordinates coding agents across research tasks and adds automated baselines and ablations to test whether an apparent result holds up. Co-founder and CEO David Ha (@hardmaru) announced the release on October 15th; the paper had been submitted to arXiv two days earlier, on October 13th. The code is available under an Apache 2.0 license.…
