Lacuna: A Research Map for Machine Learning
A living map that turns machine-learning papers into linked summaries, research directions, and testable proposals.
Research at Tiptree Systems
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.

Shared research
Papers & preprints
Two ways to explore science: map what we know, then look for what we might be missing.

Ongoing projects
Questions we’re working on now. Papers and artifacts will follow as the work is ready to share.

Cognition–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.

AI Meta-Reviewing: Verification of 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.

Behavioural Economics of LLM Agents: Decision Patterns Across Price Sweeps
Buyer–seller negotiations let us probe economic decision-making in language models. We vary prices, wording, and assigned identities to see which decisions hold up.
