Research starts
with people.
We build tools for navigating the literature, finding overlooked research directions, and testing what AI agents can do. Meet the researchers turning those questions into working systems.
Papers & preprints
Two ways to explore science: map what we know, then look for what we might be missing.
Lacuna: A Research Map for Machine Learning
A living map that turns machine-learning papers into linked summaries, research directions, and testable proposals.
Martin Weiss and 6 coauthors
The Alien Space of Science: Sampling Coherent but Cognitively Unavailable Research Directions
A way to search for scientifically coherent ideas that existing research communities are unlikely to propose.
Alejandro H. Artiles and 8 coauthors
Ongoing projects
Questions we are working on now. Papers and artifacts will follow as the work is ready to share.
Alejandro H. Artiles, Amit Sinha
Cognition and action tradeoffs in strategic language agents
Interactive agents have a finite budget for thinking and acting. TextCraft measures when reasoning, memory, and communication help enough to justify the actions they displace.
Yuan Li, Martin Weiss
AI meta-reviewing: verifying reviewer claims against manuscripts
We check reviewer claims against the manuscript, returning a verdict and supporting evidence. The system reports when the evidence or verification process is insufficient.
Soraya Ghassemlou, Martin Weiss, Tegan Maharaj, Hugo Larochelle
Behavioural economics of LLM agents: decision patterns across price sweeps
Buyer and seller negotiations let us probe economic decision-making in language models. We vary prices, wording, and assigned identities to see which decisions hold up.
