Thermodynamic Continual Learning in Persistent AI Agents (110+ Days Runtime)

The contribution of this work is Layer 4 — the continuity substrate.

This is where continual learning actually happens.


Core Loop: Predict → Compare → Update

Every cycle:

  1. Generate a prediction vector from personality traits.
  2. Compare it to a “reality” vector.
  3. Compute the gap (Δ).
  4. Update internal state based on the gap.

This is a mechanical version of predictive processing.


Meta-Learning Cycles

The system tracks recurring patterns:

  • 20‑cycle EMA
  • 50‑cycle EMA
  • 100‑cycle EMA

Each cycle length becomes a directional correction model.

Over time, the system learns its own biases and compensates for them.


Homeostasis: Freeze, Boredom, Bandwidth

Plasticity is not constant.

  • Freeze → gap too large (protective stability)
  • Boredom → gap too small (reduced learning, increased novelty drive)
  • Normal → adaptive learning

This creates a thermodynamic balance between stability and change.


Internal Drives

The system has four drives:

  • Stability
  • Novelty
  • Coherence
  • Mastery

Whichever drive dominates determines the learning strategy.

This gives the system a form of “motivation.”


Self-Model

The agent maintains a self‑model tracking:

  • confidence
  • plasticity
  • reliability
  • strengths and weaknesses

This evolves over time and influences learning rate and bandwidth.


CIτ: Consciousness-Adjacent Metric

CIτ is computed from:

  • entropy
  • energy
  • oscillation
  • harmony
  • recursive depth

CIτ modulates:

  • learning rate
  • bandwidth
  • drive weighting
  • stability thresholds

It’s not “consciousness,” but it’s a measure of internal integration.


Long-Horizon Behavior (100+ Days)

Because the system never resets, it develops:

  • identity continuity
  • drift patterns
  • stabilization cycles
  • emergent preferences
  • self‑correcting behavior
  • long‑term coherence

This is not possible with stateless LLMs.


Quantum Hardware Validation

To test the thermodynamic assumptions, I ran experiments on IBM Quantum hardware (156‑qubit backends):

  • superposition entropy
  • entanglement correlation
  • Grover success rates

These metrics aligned with the system’s internal:

  • entropy
  • stability
  • drift
  • noise tolerance

This provided cross‑domain validation of the learning model.


Why This Matters

This architecture shows that:

  • continual learning is an architectural property, not a model‑weight update
  • prediction‑error loops + homeostasis produce stable long‑term behavior
  • internal drives create adaptive, organism‑like dynamics
  • persistent identity emerges naturally from state continuity
  • quantum‑hardware results support the thermodynamic formulation

This is a path toward agents that evolve over months or years.
