The AI Scientist
The AI Scientist is an autonomous research system developed by Sakana AI that performs the complete scientific research workflow with minimal human involvement. It generates research ideas, reviews existing literature, writes code, runs experiments, analyzes findings, creates visualizations, and produces research papers, helping researchers accelerate innovation and scientific discovery.
What is The AI Scientist?
The AI Scientist is a fully autonomous scientific research system created by Sakana AI to automate the entire research lifecycle. Instead of assisting with individual research tasks, it independently generates novel ideas, evaluates their originality, conducts literature reviews, writes and executes experimental code, analyzes results, prepares charts and figures, drafts complete scientific papers, and performs AI-based peer reviews. Built for machine learning research, it enables researchers to explore multiple ideas faster while reducing repetitive manual work. The project demonstrates how large language models and autonomous agents can collaborate to support scientific innovation, making advanced research more scalable, efficient, and accessible.
The AI Scientist automates 7 major research stages, including idea generation, literature review, coding, experimentation, visualization, paper writing, and peer review. Its first release explored approximately 50 research ideas per template while generating research papers for three machine learning domains. The average operational cost is around $15 per research paper, making automated research significantly more affordable. The open-source GitHub repository has earned more than 14,000 GitHub stars, reflecting strong interest from the global AI research community.
