2025 was the Active Inference Institute's fifth full year: four Quarterly Roundtables, the 5th Applied Active Inference Symposium (November 12–14), the Theoretical Neurobiology Group joining the Institute, a new RxInfer.jl partnership, completion of the Project ~ Measurement system, and selection of the 2026 Board — a completed year in review, organized month by month. The detailed record continues to be maintained on the 2025 hub.

This retrospective maps the year month by month: new groups hosted (Theoretical Neurobiology), a new partnership (RxInfer.jl Learning Group), four Quarterly Roundtables, the Project ~ Measurement system, and the selection of 2026 leadership.
