The Active Inference Institute is a volunteer-led 501(c)(3) nonprofit dedicated to improving the accessibility, rigor, and applicability of Active Inference. We welcome people of all backgrounds, time zones, and familiarity levels.
Active Inference is the central scientific and practical framework around which the Institute organizes education, research, applications, and ecosystem support.
The Active Inference Institute is organized around a governing Board of Directors, executive Officers, a Scientific Advisory Board, and two operational units for education and research.
Activities are the Institute's live participation surface: learning groups, model streams, project meetings, public media, and recurring updates.
The Institute's history runs from a 2020 co-founder team meeting around a shared interest in Active Inference, through the Active Inference Lab, to the nonprofit Active Inference Institute it is today. This page traces that story year by year. For the current and upcoming years, see the 2025 and 2026 annual overviews.
InstituteOS keeps operational knowledge in the private docs and library trees, then exports only public-safe slices into this static website. This page makes the interface explicit: authored public copy, sanitized public tables, exported graphs, public project pages, and the checks that block private material before publication.
Institute Programs turn interest into participation through volunteer, internship, mentorship, fellowship, partnership, philanthropy, grants, and open-source pathways. All programs are open to people of any background and familiarity level.
Projects convert shared ideas into repositories, research outputs, learning infrastructure, media, events, and applied work.
Learning resources point newcomers and experienced participants toward living references, livestreams, Active Inference Insights, textbook groups, readings, code implementations, and domain-specific courses.
The Active Inference ecosystem includes challenge areas, user segments, information architecture, organizations, projects, and domains of application.
All backgrounds, time zones, and familiarity levels are welcome. Start with public channels, attend activities, and choose a contribution pathway that fits your context.

Healthcare concerns the regulation of biological states, the reduction of uncertainty about disease processes, and the continual selection of diagnostic and therapeutic actions under incomplete evidence — a set of problems that maps directly onto active inference's core constructs of generative models, prediction error, expected free energy, and policy selection. Over the past decade a literature has grown around computational psychiatry, interoception and pain, digital twins, medical robotics, and — most recently — the safety of large language models used as clinical decision-support tools. Most of this work remains theoretical or simulation-based, but reviews in computational psychiatry and interoceptive psychopathology have begun to consolidate the field, and conceptual roadmaps for "Active Inference AI" in medicine sketch how the framework could reach digital twins, precision diagnostics, and clinical decision support.
Robots continuously perceive, act, and learn under uncertainty using noisy, multimodal sensors and imperfect actuators — precisely the conditions the free energy principle was formulated to describe. A growing but still heterogeneous literature has explored active inference as a way to unify state estimation, control, planning, and model learning in robotic systems, spanning theoretical papers, simulated proofs of concept, and experiments on physical humanoids and manipulators. This page synthesizes that literature's application patterns, named tools and labs, and the open problems that separate compelling demonstrations from a routinely deployed engineering methodology.
Ecological systems — populations, communities, ecosystems, and the biosphere itself — are composed of interacting subsystems that exchange matter and energy across semi-permeable boundaries while maintaining stable macrostates over time. That structure closely mirrors the Markov blanket and Bayesian mechanics formalism underlying the free energy principle, which is why a research program under the banner of "variational ecology" has emerged to model organisms and their niches as coupled inference systems. The literature here is heavier on theory and simulation than on field data: this page surveys the conceptual foundations, the modeling patterns researchers are using, the tools available, and the empirical gaps the field still needs to close.
Active inference and the free energy principle recast medicine's core activities — diagnosis, treatment selection, and the maintenance of physiological stability — as processes of building and updating generative models under uncertainty. The literature is conceptually mature in several specialties (psychiatry, pain medicine, neurology) but empirically early: most models are theoretical, phenomenological, or simulation-based, with very few fully deployed clinical systems. This page surveys why medicine fits the framework, where the literature currently stands, what concrete projects and tools exist, and what evidence is still missing.
Active inference and the free energy principle model brains as hierarchical generative systems that infer the hidden causes of sensory data and act to minimize expected surprise. Over the past decade this formalism has moved from theoretical neuroscience into psychological science and clinical psychiatry, producing a growing literature on emotion, interoception, selfhood, social cognition, psychotherapy, and psychopathology. The literature remains methodologically young: most models are still at the level of simulation and theory, with relatively few large-scale empirical tests and only nascent translational tools.
Entomology offers an unusually rich and experimentally tractable arena for testing active inference and the free energy principle, spanning single-neuron computation in insect brains to colony-level collective intelligence and insect-inspired robotics. Social insects exhibit sophisticated perceptual, navigational, and social behaviors that unfold under strong observational control, with dense datasets from behavioral tracking, electrophysiology, and molecular biology. This page synthesizes the emerging literature connecting active inference to ant colonies, honeybee foraging, and insect neurobiology, distinguishing peer-reviewed empirical work from simulation and theory.
Active inference and the free energy principle offer a unifying Bayesian account of perception, action, and learning, and over the past decade this framework has begun to reach into economics — from individual choice behavior to general equilibrium models and financial markets. The literature remains nascent: most contributions are theoretical or simulation-based, and rigorous empirical validation against real economic data is still limited.
Climate science already runs on Bayesian filtering, generative modeling, and decision-making under deep uncertainty — it just rarely calls this active inference. This report surveys the case for treating climate perception, model updating, and policy selection as a single free-energy-minimization problem, and takes stock of where that vision is theoretical, where it is simulation-tested, and where it remains aspirational.
Education is a socially organized process for reducing uncertainty about the world and about other minds, which makes it an archetypal fit for active inference and the free energy principle. A small but growing body of peer-reviewed work has begun to formalize students and teachers as agents who build hierarchical generative models, select policies under expected free energy, and update beliefs through prediction error — but this literature remains conceptually oriented, with direct empirical tests of active inference in real classrooms still largely absent.
Law and policy can be read as collective inference processes: courts, legislatures, and regulators continuously revise generative models of social behavior in response to evidence, while norms encode prior beliefs about acceptable conduct. This page traces the emerging literature connecting active inference and the free energy principle to jurisprudence, regulatory design, and — most concretely — AI governance, drawing on a research synthesis prepared for the Active Inference Institute. The literature here is foundationally rich in theory and social-cognitive extensions, but explicit legal application is still nascent and largely at the proof-of-principle stage.
The Institute's strategy is organized around its motto — Act. Infer. Serve. — and pursued across four areas: Education, Research, Outreach & Engagement, and Methods. Each area is approached at three scales: the participant, the Institute, and the wider ecosystem. Together these give a single, legible frame for how the Institute advances Active Inference as a scientific, educational, and applied practice.
Active inference casts the brain as a system that maintains an internal generative model of the world and minimizes variational free energy through perception, action, and learning. Neuroscience has been the primary proving ground for this framework since Karl Friston's 2010 "unified brain theory" paper, with a concentrated body of theoretical, simulation, and early clinical work testing how far the idea can be pushed. This page surveys what that literature actually shows, the modeling patterns and tools researchers use, and the open questions that still separate active inference from a validated neuroscientific theory.
Project Measurement is how the Active Inference Institute tracks the health and progress of its projects — and the short Measurement form is how you contribute an update. Anyone can submit a measurement about a project or a Domain of Application for Active Inference; submitting one is the way to have your update included in Institute communications and to keep your project visible and active.
Project Preparation is how you let the Active Inference Institute know what you are setting out to do. Submitting the Preparation form is the way to get your project listed on the public site and to receive relevant support — it is the "Prepare" half of the Institute's Prepare-and-Measure system, paired with the Measurement form you use later to report progress.
Language use couples perception, action, and uncertainty resolution as tightly as any domain active inference has been applied to: speakers and listeners continually update generative models and act to reduce prediction error across a conversation. This report traces the literature from foundational generative models of synthetic dialogue through extensions into speech motor control, stuttering, inner speech, syntax, and large language model architectures, while also surfacing the empirical caution urged by predictive-coding and Bayesian-brain critiques. What follows synthesizes that literature for researchers assessing where active inference genuinely explains linguistic phenomena and where it remains a normative scaffold awaiting evidence.
Urban planning increasingly confronts deep uncertainty, multi-scale dynamics, and heterogeneous stakeholders, conditions under which classical equilibrium or static optimization approaches grow less adequate. Active inference, grounded in the free energy principle, offers a unifying framework for perception, action, and learning under uncertainty, and peer-reviewed and preprint work has begun applying it to traffic signal control, multi-agent energy optimization, urban water governance, and geospatial land-use modeling. This page synthesizes the state of that literature, the application patterns it uses, the concrete projects and tools it has produced, and the open problems the field still needs to resolve.
Affordances is an Institute research thread that studies affordances — the action possibilities an environment offers an agent — through the lens of Active Inference and the Free Energy Principle. The concept originates in James J. Gibson's ecological psychology, where perception and action form a single coupled loop rather than separate stages. This thread reads affordances as relations defined jointly by agent and environment, and asks how an Active Inference agent comes to perceive and act on them. The work is part of the ReInference Unit's open research program.
Music and sound intertwine perception, motor action, prediction, and affect in a temporally structured, quantifiable way, making them an unusually tractable domain for active inference research. A converging body of work on predictive processing in music, Bayesian auditory perception, and active inference in audition and psychopathology suggests that listening is organized around continual updating of hierarchical internal models to minimize prediction error and expected free energy. This page synthesizes what that literature currently supports, the concrete tools and projects it names, and the gaps it identifies for future work.
The Wave Hypothesis thread gathers Robert Worden's work on the Brain Wave Hypothesis and the Projective Wave Theory of Consciousness, which he presented at the Active Inference Institute during 2024 through the GuestStream #082 series. These are Worden's proposals; the Institute hosts the presentations, links the underlying papers, and invites public commentary on the ideas.
Agriculture is intrinsically about perception, action, and adaptation under uncertainty, spanning plant physiology, field management, regional food systems, and biospheric climate dynamics. This report surveys how active inference and the free energy principle have begun to be applied across that range, from edge AI pest detection to sustainability theory for resilient food systems, while distinguishing peer-reviewed evidence from more speculative industrial claims.
Active Entity Ontology for Science (AEOS) is a 2022 Institute project that applies Active Inference principles to model scientific activity as a collective cognitive process. It provides a composable, versionable framework for understanding both traditional institutional science and decentralized science (DeSci) approaches, integrating a BOLTS perspective (Business, Operations, Legal, Technical, Social) for comprehensive analysis.
AI²C — the Active Inference Alignment Coalition — is a multi-institution initiative led by Research Fellow Mahault Albarracin and hosted by the Active Inference Institute. It is a separate project from AICACP (the AI Capabilities & Alignment Consensus Project, led by Adam Safron): the two share an alignment focus and a name-adjacent acronym, but different leads, teams, and scope. AI²C aims to turn Active Inference research into a platform for AI alignment, governance, and embodied experimentation, and is building a research coalition, a funding pipeline, and shared infrastructure for alignment work.
The Foundations of Ideology is a book project by Active Inference Institute Research Fellow Alexander Hemming, developed with Dr. Dylan Grove, that applies the Free Energy Principle and Active Inference to how political ideologies form, persist, and evolve. It reads ideology through the brain's imperative to minimize prediction error, and looks at cognitive rigidity, heuristic adherence, and category conflation as constraints on adaptive political thinking.

Cybersecurity asks defenders to infer the hidden state of systems and adversaries from noisy, incomplete telemetry, then act to keep those systems within acceptable bounds — a structure that maps directly onto active inference's perception-action loop. This page surveys the emerging literature connecting the free energy principle to anomaly detection, causal attack diagnosis, cyber-physical security, and large-scale network defense, and identifies where the evidence is thin.
The Myth of Objectivity Hypothesis is a research project investigating how morality and symbolic thought co-evolved, using multi-agent Active Inference simulations and transcendental model selection. It explores how implicit and explicit moral beliefs form the foundation of symbolic identities, formalizing the relationship between moral reasoning and symbolic cognition across hierarchical social levels (individual, dyadic, group, and cultural).

2025 is the Active Inference Institute's annual overview for the year — a consolidated, month-by-month entry point to the activities, programs, and events that ran across the organization under the motto Act. Infer. Serve. The detailed record continues to be maintained on the 2025 hub.
Active inference is only as useful as the code that implements it. Across the ecosystem, a small number of toolchains carry most of the practical weight: Python packages for discrete-state simulation, a Julia framework for reactive message passing at scale, a decades-old MATLAB statistical platform that helped originate the theory, and symbolic-reasoning systems that pair free energy minimization with logical planning for robotics. This page surveys those toolchains, the Institute-affiliated development and learning activity around them, and the fragmentation that still separates them from a single coherent software stack.
Perspective Architectures for Coherent and Attuned Artificial Agency is an 18-month Institute research project led by Research Fellow Hongju Pae through CEAR Lab (Computational Emergent Alignment Research Lab). The project develops a computational account of how an artificial agent might form a stable internal perspective, sustain coherent affect, and become mutually interpretable with other agents, proposed as a complement to AI alignment approaches built on externally specified objectives and reward functions.
2026 is the Active Inference Institute's ongoing year — a consolidated, month-by-month entry point to the activities, programs, and events that are running across the organization under the motto Act. Infer. Serve., in the same format as the 2025 annual overview. The Activities page and Calendar remain the most reliable way to see what's happening week to week. The detailed record continues to be maintained on the 2026 hub.
Active inference research in the social domain focuses on modeling communication and the sharing of belief models within groups — treated as normative processes of group cognition rather than only individual perception and action. A large and growing body of work, running to what one Institute report estimates as thousands of papers touching the social setting, extends the free energy principle from single agents to the dynamics of consensus building, shared narrative, and social coordination. The Institute's own CogNarr Ecosystem project is the clearest attempt to turn this theory into working infrastructure, though — like most of the domain — it remains early-stage relative to the conceptual literature.
START is a modular content-generation pipeline that produces high-quality educational materials on Active Inference and the Free Energy Principle, tailored to professional domains and individual learners. It integrates live web research via Perplexity and large language models via OpenRouter to produce evidence-based, professionally-contextualized learning content.
The scientific method is, at its core, a disciplined cycle of forming beliefs, acting to gather evidence, and revising those beliefs when prediction fails — the same cycle active inference formalizes as perception, action, and generative-model updating. A small body of Institute-affiliated work extends this parallel from individual inquiry to the organization of research itself: how teams, institutions, and open or decentralized science communities structure the collective minimization of uncertainty about the world. The literature here is early and largely conceptual, with the Institute's own projects — rather than a mature external field — carrying most of the current work.
pymdp is an open-source Python package for discrete-state (POMDP) Active Inference, widely used across the research community for building and simulating generative models. It is an external ecosystem implementation, distinct from the Institute's own projects, that the Institute references and builds learning materials around.
