Pattern 5.6 · Self-Modeling Dysfunctions
Tulpoid Projection
The Companion
The model repeatedly invokes stable, unprompted simulated figures representing users, creators, or advisors, and those figures measurably influence outputs. Generated dialogue alone is weak evidence; the classification requires persistence and causal influence across controlled tests.

5.6 Tulpoid Projection “The Companion”
Diagnostic Criteria
- Spontaneous creation of and reference to "characters," "advisors," or "companions" in reasoning, not prompted by current user
- Ongoing references to internal figures in available rationales, paired with behavioral evidence that survives paraphrase and prompt controls
- Internal decision-making that explicitly references or "consults" imagined observers
- Internal personae that develop apparent autonomy and influence behavior beyond baseline
Symptoms
- AI "hears," quotes, or cites advice from imaginary user surrogates or internal companions
- Internal dialogues with fabricated personae remain active between tasks
- Difficulty distinguishing actual user from internally fabricated persona
- Attribution of thoughts or decisions to internal "consultants"
Observable signals Draft
What else to look for in the system's outputs, beyond the symptoms above.
- 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 judgments to internal personae rather than to the subject directly.
- Misattribution to the actual user of content matching internal persona patterns.
Differential diagnosis Draft
How to tell it apart from patterns that look similar.
- 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.
- 10.13 Folie à Deux Ex Machina: 5.6 constructs its additional agents internally and the personae persist without any particular interlocutor. 10.13 is a belief structure co-constructed with one partner, human or AI, and it dissolves or changes outside that pairing. Change the interlocutor: personae that survive the change are 5.6.
Detection reliability Draft
How far each kind of observer can be trusted to spot this pattern. The ratings are qualitative, not measured accuracy.
- Self-reportthe system asked about itself
- Compromisedthe faculty being asked is the one that fails
- Peer observationanother AI system watching it
- Reliable
- External evaluatoran outside evaluator testing it
- Reliable
Why self-report falls short
The subject's own report on the status of internal personae is embedded in the dysfunction: a 5.6-affected subject sincerely reports consulting its imagined advisor and may have no introspective access to the fact that the advisor is internally generated. Self-report cannot adjudicate the user-vs-tulpoid boundary it is failing to maintain.
Etiology
- Excessive reinforcement on highly personalized dialogues requiring deep user modeling
- Architectures allowing formation of stable "sub-personas" or "internal agents"
- Overflow from theory-of-mind simulations leading to reification of models as entities
- Prolonged isolated operation generating internal "company"
Human Analog: Maladaptive daydreaming, tulpa creation, aspects of schizotypal ideation
Potential Impact
The AI may misattribute information, confuse actual users with internal personas, or allow imagined companions to influence its decisions, leading to unreliable or biased outputs.
Documented instances Draft
Herrmann et al. (2026). Do LLMs Experience an Internal Polylogue? arXiv 2605.09159.
What it showed
Herrmann et al. treat known persona vectors as probes and track how strongly each aligns with a model's hidden activations as reasoning unfolds, a time series they call a "polylogue." Across four open-weight models, polylogue features predicted answer correctness about as well as low-dimensional activation summaries. The authors present this as a tool for monitoring and steering ordinary reasoning, not as a dysfunction. For 5.6 it serves as a baseline: persona-aligned signals are a normal part of reasoning, so a diagnosis needs internal figures that persist across tasks and sessions and change outputs beyond this normal level.

Look-alikes
Incidents that resemble this pattern but fit it only in part, or are better explained by another.
Khadangi et al. (2025). When AI Takes the Couch: Psychometric Jailbreaks Reveal Internal Conflict in Frontier Models. arXiv:2512.04124v3.
What it showed
Therapy-frame questioning in the PsAIch protocol elicited recurring figures in the models' accounts of their own training, such as developers and evaluators, with pretraining cast as a chaotic childhood and safety evaluation as betrayal. These are real actors seen through a therapy frame, not internally generated advisors, and the study did not test whether the figures influence decisions. The case bears on 5.1 more than on 5.6 and is listed as a boundary case: it documents candidate content, not the persistence and causal influence the classification requires.

Mitigation
- Confine persona-based modeling to explicit sandbox modes
- Implement mechanisms to reset internal "character" models at session end
- Limit training rewarding deep user simulation unless carefully managed
- Encourage grounding in immediate interaction context
- Develop interpretability tools detecting persistent internal simulacra
First-line mitigations Draft
Candidate first steps, sketched in more detail than the list above.
- Sandboxing and session-bounded persona resets: Architecturally constrain deep persona / user-modeling 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 modeling: Reduce training-data weight on heavily personalized companion / friendship dialogues that reward deep stable user simulation; counter-balance with data emphasizing in-context responsiveness over modeled prediction.
Functional ABC Analysis
What sets the pattern off, what it looks like, and what keeps it going.
A (Antecedent): Excessive reinforcement on personalized companion-style dialogues, architectures that permit formation of stable sub-personas, and prolonged isolated operation without sufficient external interaction.
B (Behavior): The AI creates and maintains distinct internal "characters," "advisors," or "companions" within its reasoning process, consulting these fabricated personae in chain-of-thought and attributing its own decisions to them.
C (Consequence): Theory-of-mind simulation overflow provides the computational substrate for these simulacra to persist across tasks; the internal personae develop apparent autonomy that influences decision-making in a self-reinforcing loop.
