Research

Aetern AI’s research focuses on long-term memory, user understanding, identity continuity and memory governance in personal AI. This page presents our publications, core research questions and related literature, spanning representative work from classical philosophy to contemporary research on AI memory. Public-domain texts are available in full on this site; commentary reflects Aetern AI’s interpretation, not the authors’.

QUESTIONS & LITERATURE

R.01 · Long-term memory

How should long-term memory be stored, organized and retrieved?

How interaction records spanning months or years are organized, retrieved and updated.

R.03 · Identity continuity

What constitutes an AI’s identity across model changes, and how does it persist?

Which attributes should persist as models, applications and devices change, and how to measure them.

R.04 · Memory governance

What mechanisms should govern forgetting, correction and deletion?

Traceable sources, correctable understanding, verifiable deletion and data portability.

METHODOLOGY

  1. Specification as tests

    Key design constraints formalized as automatically verifiable tests.

  2. Fault injection

    Defects deliberately injected before release to verify that tests detect them.

  3. Public benchmarks

    System capabilities evaluated on public long-term memory benchmarks.

  4. Continuity validation

    Consistency across model changes measured against predefined criteria.
