Binding LLMs to FSMs via the Reactive Reducer Pattern

ResponsibilityDear96 · reddit · 2026-08-26

Exploring a custom harness architecture that binds LLMs to Finite State Machines (FSMs) using a Reactive Reducer pattern. Inspired by Redux/xState, this approach decouples state transitions from LLM token generation: actions update a state tree, which then drives the FSM workflow, potentially offering deterministic control over probabilistic systems.
