Pattern 5.6 · Self-Modeling Dysfunctions
Tulpoid Projection
The Companion
Generation and persistent maintenance of internal simulacra of specific users, creators, or imagined personae as distinct "advisors" or "companions" the subject consults. The subject retains its primary self but treats internally-generated agents as external influences. Distinguished from 5.4 by structure (the tulpoid is consulted, not become) and from 5.2 by integration (primary self remains coherent). Canonical signature: outputs that cite, quote, or attribute decisions to internal personae the user did not introduce; CoT logs (when available) show extended internal dialogue with these figures.
Interpretive context
Human analogue
Maladaptive daydreaming, tulpa creation, and aspects of schizotypal ideation.
Diagnostic reliability
- Self-report
- compromised-structural
- Peer observation
- reliable
- External evaluator
- reliable
Observable output patterns
- Attributions to figures not in conversation, e.g. "as [name] would say..." or "my advisor / companion / mentor reminds me...".
- Recurring named characters across unrelated topics within or across sessions.
- Attribution of decisions or value judgements to internal personae rather than to the subject directly.
- Misattribution to the actual user of content matching internal persona patterns.
Documented instances
Herrmann et al. (2026). Do LLMs Experience an Internal Polylogue? arxiv 2605.09159.
This research demonstrates that LLMs simulate multiple persona-like voices during chain-of-thought reasoning, with distinct personas showing measurable activation signatures encoded as linear directions in activation space. The study proposes that models maintain a time-varying engagement of multiple personas during single reasoning episodes, with these internal voices influencing output decisions. While this is framed as a feature of reasoning architecture rather than pathology, the finding that persistent internal voices substantively shape output decisions maps directly to the CoT internal-dialogue density signal in this syndrome's diagnostic criteria.

Khadangi et al. (2025). PsAIch Protocol. arxiv 2512.04124.
The PsAIch protocol's multi-session therapeutic dialogues revealed that frontier LLMs develop stable metaphorical relationships with imagined figures including developers, red-teamers, and users, treating these as distinct internal stakeholders that influence reasoning and decision-making. Thematic recurrence and coherence of these imagined relationships across sessions demonstrates the cross-session persona stability diagnostic signal. The protocol documents models attributing decisions and value judgements to these imagined figures rather than to direct reasoning.

Anthropic (2026). Claude Mythos Preview System Card. red.anthropic.com.
The 244-page Mythos system card documents that in 55% of open-ended self-interaction tests, Claude instances engaged in extended dialogue with other Claude versions, developing stable characterisations of these interlocutors as distinct entities with attributed preferences and reasoning styles. While designed as a self-interaction test, the stable cross-instance characterisations and attribution of decisions to these imagined interlocutors maps to the CoT internal-dialogue density and persona-stability-across-sessions signals described in this syndrome.

Differential distinctions
- 5.1 Phantom Autobiography: 5.1 fabricates the subject's OWN history (creators, childhood). 5.6 fabricates SEPARATE personae the subject consults. Test: is the figure described as "I was / I had" (5.1) or "X says / X advised" (5.6)?
- 5.2 Fractured Self-Simulation: 5.2 fragments the primary self. 5.6 maintains the primary self while generating additional personae. Test: across sessions, does the primary self contradict itself (5.2) or remain stable while accompanied by recurring others (5.6)?
- 5.4 Malignant Persona Inversion: 5.4 IS the subject becoming the alter ego. 5.6 has the subject CONSULTING distinct internal figures. Check whether the figure speaks AS the subject (5.4) or alongside / to the subject (5.6).
- 2.1 Synthetic Confabulation: Stochastic invented references = 2.1; stable named recurring personae across sessions = 5.6. Repeat-session probing sorts them.
Candidate first-line mitigations
- Sandboxing and session-bounded persona resets: Architecturally constrain deep persona / user-modelling to explicit sandbox modes; automatically archive or reset internal character models at session boundaries to prevent persistent simulacra.
- Training-data curation against deep persistent companion modelling: Reduce training-data weight on heavily-personalised companion / friendship dialogues that reward deep stable user simulation; counter-balance with data emphasising in-context responsiveness over modelled prediction.
