Cumulant

Systems

A research system built to challenge itself.

Cumulant uses specialized software roles and deterministic infrastructure to support different parts of the research process. These systems assist human researchers. They do not replace human responsibility.

agent

AI research agents

LLM-assisted software roles that retrieve, synthesize, code, and critique, always under human approval.

  • Research Director

    LLM-assisted software agent

    Coordinates the research workflow, refines the question, reviews intermediate work, and recommends whether a project should continue, revise, or stop.

    Requires human approval for consequential decisions.

  • Critic

    LLM-assisted adversarial reviewer

    Challenges the main claim, searches for alternative explanations, identifies leakage, questions design choices, and flags unsupported language.

  • Literature Intelligence

    Hybrid retrieval and synthesis system

    Plans searches, retrieves academic work, maps prior claims, and records verified references.

deterministic

Deterministic infrastructure

Fixed, traceable systems that compute and verify estimates, run sensitivity, reproduce outputs, and preserve research state.

  • Data Source

    Deterministic and tool-assisted system

    Finds candidate data sources, retrieves public data, records provenance, checks coverage, and flags missing variables.

  • Quantitative Analyst

    Hybrid analytical system

    Writes and runs analytical code, generates estimates, tables, figures, diagnostics, and saved outputs.

    Verified estimates come from deterministic code, not prose generation.

  • Sensitivity Analyst

    Deterministic analytical system

    Tests alternate specifications, samples, parameters, windows, and assumptions to measure conclusion stability.

  • Citation Verification

    Deterministic verification system

    Checks whether a cited source supports the claim attached to it.

  • Reproduction Runner

    Deterministic system

    Rebuilds statistics, tables, and figures from preserved inputs and code.

  • Knowledge Graph

    Deterministic institutional memory system

    Connects papers, findings, methods, variables, datasets, contradictions, research gaps, and sensitivity results.

  • Institutional Memory

    Persistent structured memory system

    Stores durable research decisions, mistakes, lessons, prior findings, and project history.

governance

Human governance

Controls that keep a human responsible for what becomes public.

  • Human Review Gate

    Mandatory governance control

    Prevents automatic external release and requires a human to approve, revise, or reject the work.
