World Model Initiative research and the Decision Lineage Protocol

Proposes a governed world model: a business's own account of what it intends, what it has promised, who may decide and what has happened, kept under its own authority. The Decision Lineage Protocol (DLP) is the open protocol such a world model is designed to run on. A learned predictive model plugs in through a socket, and its output stays provisional until a person reviews and accepts it.

Who may decide what, on what evidence, and how is the record kept when people and AI agents both act?

Status. Published research and an open specification (version 3.0.0, Apache 2.0), with a scoped formal result. The engine (DLP reference implementation) is under construction; the public demonstration is a fixed snapshot.

Beer

Stafford Beer · 1972 · Shared & situated models

Brain of the Firm and Project Cybersyn

Organizational cybernetics links recursive coordination with operational information. Beer's 1973 account describes real-time operational information for Chilean economic management, the project later known as Cybersyn.

How can a distributed organization maintain viability and coordinated awareness?

  • Documented engagement · AshbyControl-relevant distinctions and regulationSmith's report builds on Ashby's law of requisite variety: governance must match the variety of what it governs. Her governed world model adds rules for who may change goals and the model, and keeps the earlier record.

  • Documented critique · LeCunLearned predictor and governing environmentSmith's definition report assesses LeCun's 2022 definition against her proposed ingredient list. In her framing a learned predictor such as JEPA is a different kind of model that can plug into a governed world model through a socket, its output provisional until a person accepts it. A difference of scope, not evidence that JEPA cannot support memory or planning.Smith, The World Model Definition (TR-D-001)
  • Interpretive affinity · HutchinsCognition across people, tools and proceduresHutchins studies cognition spread across people, tools and procedures. Smith proposes a governed world model in which decisions by people and AI agents are attributed and kept with their evidence.

This comparison does not claim that shared world-model infrastructure originated with WMI.Decision Lineage Protocol specification, version 3.0.0
  • Interpretive affinity · MinskyA model's relevance depends on its userMinsky makes a model's adequacy relative to its user's questions. Smith's specification gives each role a projection of the same world model, and adds a constraint: no projection may add governance.Decision Lineage Protocol specification, version 3.0.0
  • Interpretive affinity · Chu et al.Revision of state and revision of the modelBoth separate producing outputs from revising the model, and both gate revision: Chu and colleagues' Evolver passes regression and rollback checks.

Scope, coding and sources

Coverage
Selected researchers and collaborations who shaped the idea of a world model, from 1894 to 2026, and the World Model Initiative’s own work, shown alongside them. A selection, not a census.
Unit
Usually one selected work per researcher or collaboration, labelled by last name. The Smith entry is a 2026 body of work rather than a single paper, so it carries more themes than most entries.
Dates
Years of publication of the selected work, not lifespans. Later revisions are named in the source notes.
Links
A documented link means the cited work discusses the other explicitly. It is not endorsement, collaboration or established influence. Interpretive links, affinities and contrasts, are editorial comparisons. Arrows mark documented influence.
Themes
Themes are editorial coding of each work’s concerns, including the ones it critiques. Sharing a theme does not mean agreement, and a missing theme means the emphasis was not coded, not that it is absent.
Boundaries
Historical figures did not all use “world model” in its current sense. “Shared” means a representation maintained across activities or agents.
Sources
Every entry links its public source. Each summary was checked against its source in two independent passes, one confirming the source says it and one looking for a stronger reading than the source supports. Last checked 6 October 2026.

Smith emphasizes institutional purpose, authority, commitments and decision lineage. This comparison does not claim that shared world-model infrastructure originated with WMI. Decision Lineage Protocol specification, version 3.0.0
  36. Minsky and Smith · Interpretive affinity · A model's relevance depends on its user. Minsky makes a model's adequacy relative to its user's questions. Smith's specification gives each role a projection of the same world model, and adds a constraint: no projection may add governance. Decision Lineage Protocol specification, version 3.0.0
  37. Chu et al. and Smith · Interpretive affinity · Revision of state and revision of the model. Both separate producing outputs from revising the model, and both gate revision: Chu and colleagues' Evolver passes regression and rollback checks. Smith's emphasis is who has the authority to approve a change, and that the earlier record is kept. Similar structure does not establish operational equivalence. World Model Initiative Series, Volume I · DOI 10.5281/zenodo.21073276
  38. Brooks and Smith · Interpretive contrast · How much persistent shared representation?. Brooks demonstrates situated behavior with reduced reliance on centralized world representations. Smith's target includes institutional commitments and decision history that must persist across people and agents. Their differing domains explain part of the distance; neither comparison establishes a universal winner. World Model Initiative Series, Volume I · DOI 10.5281/zenodo.21073276

  40. Minsky and LeCun · Interpretive affinity · Sufficiency depends on use. Minsky defines adequacy through an observer’s questions; LeCun’s configurator and abstract prediction make relevance a design problem for an agent. LeCun, A Path Towards Autonomous Machine Intelligence (OpenReview)
  41. Kalman and LeCun · Interpretive affinity · Compact predictive state. Both use a state representation to support prediction. Kalman specifies probabilistic estimation in a given dynamical model; LeCun proposes learned representations and modular planning. LeCun, A Path Towards Autonomous Machine Intelligence (OpenReview)
  42. Bellman and Sutton · Interpretive affinity · Planning from transitions. Bellman formalizes sequential choice with a transition model. Dyna combines learned models, planning updates, and real experience; this edge marks conceptual continuity. Sutton, Integrated Architectures for Learning, Planning, and Reacting (ICML 1990), author's copy
  43. Wiener and Sutton · Interpretive affinity · Act, observe, update. Both couple action to subsequent evidence. Cybernetic regulation and reinforcement learning organize that feedback around different mathematical objectives. Sutton, Integrated Architectures for Learning, Planning, and Reacting (ICML 1990), author's copy
  44. Simon and LeCun · Interpretive affinity · Bounded, task-relative intelligence. Simon emphasizes limited computation and structured environments; LeCun’s architecture selects abstractions and planning levels for the task. This is a comparison, not an influence claim. LeCun, A Path Towards Autonomous Machine Intelligence (OpenReview)
  45. Ashby and Chu et al. · Interpretive affinity · Adaptation at multiple levels. Ashby studies regulation and adaptive organization; Chu and colleagues separate prediction, simulation, and persistent model revision. The levels are related questions, not equivalent formalisms. Chu et al. — Agentic World Modeling, v3
  46. Beer and Sakagami et al. · Interpretive affinity · A maintained world shared by activities. Beer’s organizational coordination and Sakagami’s robotic information component both rely on maintained shared representations; their authority and physical-control problems differ. Sakagami et al. — Robotic world models
  47. Bateson and Clark & Chalmers · Interpretive affinity · Where cognition begins and ends. Both move the explanatory boundary beyond an isolated individual, through feedback circuits or reliably coupled external resources. Their criteria and philosophical claims differ. Clark and Chalmers — The Extended Mind
  48. Deutsch and Hutchins · Interpretive affinity · Collective information processing. Deutsch models political communication and learning; Hutchins examines coordinated cognitive work in navigation. Both make organization relevant to information processing. Hutchins — Cognition in the Wild, author’s account
  49. Hutchins and Clark & Chalmers · Documented influence · Distributed cognition as a cited precedent. Clark and Chalmers cite Hutchins (1995), the navigator's slide rule and work on cognitive collectives, as examples when arguing that external resources can take part in cognition. Clark and Chalmers — The Extended Mind
  50. Gibson and Brooks · Interpretive affinity · Environmental structure does explanatory work. Gibson emphasizes active pickup of environmental information; Brooks emphasizes situated perception–action coupling. This is thematic affinity, not a claim of identical theories. Brooks — Intelligence without Representation
  51. Dreyfus and Brooks · Interpretive affinity · Situated challenges to centralized symbols. Dreyfus questions whether symbolic programs can capture relevance and ambiguity; Brooks demonstrates robot architectures that reduce reliance on centralized world representations. Brooks — Intelligence without Representation

  56. Leontief and Forrester · Interpretive contrast · Economic interdependence, different dynamics. Leontief's input-output structure tracks sectoral dependence; Forrester emphasizes feedback and decision policies that generate behavior over time. Forrester, The Beginning of System Dynamics (author's retrospective, 1989)
  57. Lorenz and Shanghai AI Lab · Interpretive affinity · Limits of predictive representation. Lorenz exposes sensitivity to initial conditions; the Shanghai roadmap emphasizes partial observation and bounded compression. More detail alone does not settle useful predictive horizons. Chen et al. — A Definition and Roadmap for World Models
