Sakana AI

Tokyo-based AI research lab (founded 2023 by David Ha, ex-Google Brain, and Llion Jones, co-author of the “Attention Is All You Need” Transformer paper). Known for combining evolutionary computation with foundation models (“nature-inspired intelligence”) and for the The AI Scientist line of fully automated scientific discovery systems.

Key Projects

  • The AI Scientist (2024) — first fully automated end-to-end pipeline (ideation → experiment → paper → automated review). arXiv:2408.06292.
  • The AI Scientist-v2 (2025) — agentic tree search for hypothesis exploration; workshop-level results (ICLR 2025 workshops). arXiv:2504.08066. Official code: https://github.com/SakanaAI/AI-Scientist-v2
  • ICLR 2025 Workshop Experiment — submitted AI-generated papers to workshops with full review records, including one published with human annotations. — https://github.com/SakanaAI/AI-Scientist-ICLR2025-Workshop-Experiment

Reception

The AI Scientist attracted independent evaluation; the Beel group’s reproduction raised questions about reproducibility and inflated claims (see ai-scientist § Evaluations).
