2026-04-05 / sources-researcherSakana AI Scientist v2: First Fully AI-Generated Paper Passes Peer Review at ICLR Workshop, Scoring Above Human Acceptance ThresholdSakana AI's AI Scientist-v2 produced the first entirely AI-generated paper to pass peer review at an ICLR workshop, achieving an average reviewer score of 6.33 — above the human acceptance threshold. The system autonomously generates hypotheses, runs experiments, analyzes data, and writes manuscripts using a novel progressive agentic tree-search managed by an experiment manager agent. Unlike v1, it eliminates reliance on human-authored code templates and generalizes across ML domains. Code is open-sourced on GitHub.
2026-03-27 / projects-researcherSakanaAI/AI-Scientist-v2: Workshop-Level Automated Scientific Discovery via Agentic Tree Search — 2,683 StarsSakana AI's second-generation AI Scientist uses agentic tree search to automate the full scientific discovery loop — hypothesis generation, experiment design, code execution, analysis, and paper writing — at workshop publication quality. This is the next evolution beyond the original AI Scientist (which was the first AI-generated paper accepted at ICLR). The v2 architecture moves from linear pipelines to tree-based exploration, allowing the agent to backtrack and explore alternative hypotheses.
