ActiveGraph makes the agent trace the runtime: Yohei Nakajima’s open-source Python runtime treats an append-only event log as the source of truth, enabling replay, forking, and lineage for long-running agents. Paper and v1.2.0 are live now.

Yohei Nakajima open-sources Active Graph, an event-sourced reactive graph runtime for long-running agents that provides persistent state, fork-and-diff agent runs, and full auditability, representing a new paradigm in agent architecture.
The Log Is the Agent
This paper introduces ActiveGraph, a runtime that makes the append-only event log the central source of truth for agentic systems, enabling deterministic replay, cheap forking, and end-to-end lineage from goals to model calls.
