Thymos Cognition that evolves with experience.
Thymos is Aetherya’s cognition architecture. Myrias, the current model built on it, makes every decision a simulated person takes. A language model reads the situation and reports what a person would notice. It never picks the option. Myrias does, carrying what that person has already seen and where they stand when the choice arrives.

A message can feel convincing at one moment and uncertain at another. Confidence can grow. Friction can compound. Prior experience can reshape the next decision. Thymos brings this continuity to Aetherya’s simulated people — shaped by context, memory, changing perspective, and human variation.
People change as experiences accumulate.
Experience carries forward.
Every interaction becomes part of the simulated person’s journey, giving later responses continuity and context.

Responses evolve.
Perception, confidence, and intent can shift as circumstances change and new information appears.

People remain distinct.
Different simulated people can interpret the same experience through their own priorities, histories, and decision tendencies.

Compared withobserved outcomes.
Aetherya compares simulated predictions with research findings, rollout metrics, and real-world outcomes. Those comparisons inform calibration and clarify where confidence is strongest. Evidence is presented with scope, version, methodology, and known limitations.
