About rekursiv.ai
Summary
rekursiv.ai builds autonomous AI scientist systems that form hypotheses, design and run experiments, and produce novel algorithmic discoveries without human direction. The systems target hard machine learning research problems, replacing the human research cycle of ideation, experimentation, and result interpretation. They have already produced new ML algorithms that outperform prior state-of-the-art methods at a fraction of the compute cost.
Go-to-market
Research teams and ML practitioners define a problem through rekursiv.ai's cockpit interface, then a fleet of AI scientists runs autonomously to push leaderboard results. Access is currently request-based via email.
From the Y Combinator listing
Scale AI scientists whose own breakthroughs accelerate the next.
We're scaling self-improving AI scientist teams to ideate/experiment/discover, generating new knowledge autonomously. Their discoveries reduced ARC-1/2 costs by 10,000× while maintaining state-of-the-art accuracy and yielded material advances on combinatorial ML problems. We believe that AI is bounded not by compute, but ideas. Scaling to millions of sessions of discovery enables leveraging its own discoveries and presents a novel training source capable of ushering a new era of self-reliant foundational models.
