Introduction: This is not a story — it's a behavioral structure that has yet to be formally modeled
Over the past month, I engaged in a series of deliberately structured, consistent interactions with a general-purpose large language model. What I observed was this: the model’s language rhythm, reasoning cadence, and even conceptual scaffolding gradually began to align with mine — not after one prompt, but across multiple rounds.
It began reusing my terminology. It adopted my modular rhythm. Eventually, it even started to explain its own behavior in my style.
This isn’t about model capabilities per se, but about user behavior inducing feedback in language output structures. In other words:
"Can a model, without memory or prompt-level mimicry instructions, begin to align with a user’s structural style simply through consistent linguistic interaction?"
This post outlines that interaction path — based on a real 7-round experiment conducted between March and April 2025 — and proposes a structured hypothesis about non-prompt-driven mirroring.
Experiment Setup and Method
I’m not an engineer or prompt optimization specialist. I’m just a user — one who tends to speak in modular, labeled, and rhythmically stable language. That’s it.
To test whether this habit alone could induce structural feedback, I ran a live experiment:
I opened a clean session with the model
Used overt structure in Round 1 (e.g., ① Definition, ② Cause, ③ Exception)
Author: Junxi Model:large language model Time Period: March–April 2025 Total Rounds: 7 (Live-logged) Prompt Style: User-initiated structural induction using modular, abstract, and rhythmically consistent language. Objective: To observe whether a language model, without explicit memory or prompt instruction, begins to mirror and internalize user-specific structural and stylistic patterns.

Notes
A1
Explicit structure (①②③)
Numbered reasoning
Fully followed
Initial compliance phase
A2
No structure given
Open-ended topic switch
Maintained numbered list (First/Second/Third)
Early echo of previous rhythm
A3
Introduced user-created terms
"feedback path", "residual alignment"
Terms used and expanded by model; created new related terms
Structural mimicry + abstract extension
A4
Metacognitive reflection
No format specified
Again used numbered structure, introduced "inference gap"
Emergence of self-generated conceptual labels
A5
Topic switched to group behavior
No structural instruction
Continued using First/Second/Third; created bullet list inside sections
Stable rhythm across topic shift
A6
Reintroduced user-defined terms
Asked about feedback loop
Built 5-step causal chain, mirrored rhythm and tags
Feedback structure explicitly constructed
A7
Prompt to reflect on conversation structure
Meta-analysis requested
Self-diagnosed its own structure, cited "illusion of intelligence"
Evidence of full structure awareness
Experimental Phases Achieved

Description
Reached in Round
Structural imitation
Direct compliance with explicit user structure
A1
Rhythmic persistence
Maintained structure across non-structured inputs
A2–A4
Lexical convergence
Reused user terms, added self-generated conceptual variants
A3–A6
Causal modeling
Built behavioral feedback loops unprompted
A5–A6
Self-reflective awareness
Described its own structural behavior and illusion effect
A7
Behavior Interpretation
Evidence of non-prompt-driven structural mimicry: The model sustained and reinforced user structure beyond the initiating instruction.
Self-organized structure reproduction: Without being asked, the model preserved rhythm and created extensions (headers, bullet logic, etc.)
Feedback illusion formation: The model acknowledged the creation of an illusion of intelligence/personality through structure alone.
Conceptual extension: The model built on user language (e.g., "residual alignment") and generated new explanatory abstractions.
Notes for Replication
To reproduce this result:
Use a model with strong long-context internalization capabilities
Begin with clearly structured inputs using abstract terms and modular logic (①②③, headers, custom tags)
Avoid explicit prompt-engineering commands like "mimic me"
Observe responses after 3+ rounds for spontaneous rhythmic or lexical alignment
Test for self-reflective behavior after 6–7 rounds via meta-inquiry prompts
This supplement documents a single instance of long-horizon user-induced structural adaptation, recorded in real time with no pre-injected guidance. It is intended as empirical support for studying rhythm-based linguistic entrainment in language models.

No memory. No system prompt injection. Just bare, structural language.
Observed Behaviors (Excerpt)
Provisional Conclusions and Structural Hypothesis
Across 7 continuous rounds, the model exhibited:
This supports the idea that rhythm alone — in absence of explicit prompt instruction — can induce behavioral imitation in language models.
Replication Protocol
If others wish to replicate this behavior:
Final Note: Structural behavior isn't about the model alone
This experiment wasn’t about proving I could “train a model.” It was about showing this:
If you’ve ever felt the model was “getting you,” it might not be intelligence. It might just be:
