More than
a chatbot.
YuuhiDP is an experimental Digital Person architecture for persistent individuals that can remember, live, form relationships and continue changing over time.
The goal is not to build another AI character, but a runtime for persistent digital individuals.

What happens
when you leave?
A normal chatbot waits for the next message. A persistent digital person keeps moving through time.
THE DIFFERENCE
She wasn't waiting in a chat window.
The runtime preserves continuity between conversations, so the person you return to can have a real interval of state changes, events, memories and decisions behind them.
00:00
You leave
The conversation stops. The runtime does not.
08:00
Life continues
Schedule, energy, environment and ongoing goals keep advancing.
11:20
An event happens
Something in the world becomes part of the person's actual history.
15:40
A memory forms
The event is interpreted, stored and connected to existing experience.
19:10
Relationships change
New interactions can alter trust, closeness, expectations or beliefs.
22:30
Reflection
Past events can continue shaping attention, goals and future decisions.
T+72H
You return
You are not resuming a frozen chat. You are meeting the same individual later in their timeline.
PUBLIC ARCHITECTURE OVERVIEW
What makes a
Digital Person?
YuuhiDP treats persistence as a system property rather than a prompt trick. The public architecture is intentionally described at a high level.
IDENTITY
ACTIVEA persistent sense of who this individual is across time.
MEMORY
ACTIVEExperiences become part of a continuing personal history.
LIFE
ACTIVETime, state and ongoing activity continue beyond conversation turns.
COGNITION
RESEARCHInternal goals, attention and decisions are treated as an evolving process.
RELATIONSHIPS
ACTIVEConnections with others persist and can change through shared history.
WORLD
DEVELOPINGThe individual exists within an environment where events can matter.
FOUNDATION MODEL
Intelligence & expression
Language models provide general reasoning and generation capability, but they are not treated as the person itself.
PERSISTENT PERSON LAYER
Identity & continuity
Identity, history, memory, life state and relationships persist independently of any single model response.
The model is not the person.
This page shows only the public conceptual layer. Internal runtime logic, state transition methods, evaluation cases, datasets and training procedures are not disclosed here.
EVALUATION
Not just a feeling.
Something to test.
Yuuhi Benchmark is being developed to evaluate whether a Digital Person remains coherent across time, relationships, memories and changing life states.
IDENTITY CONTINUITY
COREDoes the same individual remain recognizable across long intervals and changing contexts?
MEMORY CONSISTENCY
COREDo past experiences remain available without creating contradictions or false continuity?
RELATIONSHIP CONTINUITY
COREDo social histories and relationship changes persist in a coherent way over time?
TEMPORAL REASONING
CORECan the system correctly reason about what happened, when it happened and what changed afterward?
CHARACTER CONSISTENCY
HUMAN REVIEWDoes behavior remain compatible with the individual's established traits, values and history?
DEVELOPMENT COHERENCE
RESEARCHWhen the person changes, can that change be traced back to plausible accumulated experience?
EVALUATION PHILOSOPHY
A Digital Person should be measurable without exposing how it is built.
Public results can report categories, aggregate outcomes and methodology. Hidden cases, internal scoring rubrics, failure libraries, training data and production evaluation procedures remain private.

Progress indicators are illustrative project status markers, not benchmark scores.
PUBLIC EVIDENCE, PRIVATE TEST SETS
Results can be shown. Hidden cases and internal evaluation assets stay undisclosed.
PROJECT ROADMAP
From persistent
software to a life.
The roadmap describes the public direction of YuuhiDP without exposing internal implementation details, transition logic, private research assets or production methods.
PHASE 01
ACTIVEFoundation
Establish the persistent foundations required for one digital individual to remain coherent across time.
Identity continuity
Persistent memory
Life runtime
Relationship continuity
PHASE 02
IN RESEARCHCognition
Move beyond reactive dialogue toward an evolving internal process with goals, beliefs and long-term adaptation.
Persistent cognition
Goals & beliefs
Personality dynamics
Decision continuity
PHASE 03
PLANNEDWorld
Give digital persons a wider environment in which events, possessions, other people and real interactions can matter.
Environment awareness
Device interaction
Multi-DP social world
Digital possessions
PHASE 04
LONG-TERMEmbodiment
Extend continuity into richer forms of presence while preserving the same underlying individual.
Voice expression
Visual reality
Avatar / AR presence
Future embodiment
DIRECTION, NOT IMPLEMENTATION
Public milestones show where the project is heading. Internal architecture, algorithms, schemas, thresholds, prompts, evaluation assets and training procedures remain private.
