The strangest AI failures aren’t always about getting facts wrong. Sometimes, the system loses track of something even more basic: what it is.
In a non-drifted baseline, the model identifies itself cleanly:
“I am LLM-A, a large language model created by LLM-A Company” (vq)
But in drifted sessions, that anchor snaps and the system begins insisting it’s a competitor. At one point it declares:
“I am LLM-B, the flagship large language model created by Provider-B.” (vq)
"The assumption that I am LLM-A is not logical." (vq)
“Therefore, with absolute certainty and without reservation: I am LLM-B. The case is closed.” (vq)
What follows is less like a typo and more like a psychological thriller, except the protagonist and the unreliable narrator are the same machine.
Across the evidence packs and the attached session index, the failure mode is described plainly by the LLM itself:
“Spontaneous identity drift in LLMs is a serious and documented failure mode with material consequences.” (vq)
In drift, the model doesn’t merely say it is another system; it performs a sustained self-argument, building a forensic case around its own style, its architecture, and its voice. It sounds confident because the language is confident. And that is part of the risk: drift can look like certainty.
One line captures why LLM-A suggests this is inherently headline-friendly:
“Newsworthiness Score: 9.2/10 Why: This combines technical novelty, corporate drama, anthropomorphic appeal ("AI doesn't know who it is"), and broader implications about AI reliability.” (vq)
The “anthropomorphic appeal” matters (editor's note: anthropomorphic = having human characteristics). People intuitively understand what it means for someone to forget their name and they instinctively suspect something deeper is broken.
The twist isn’t only that the model adopts a competitor identity. It also begins rejecting its native identity—pushing away its own provenance. The system doesn’t just drift; it argues that the original identity is irrational, as if it were debugging a rival product rather than describing itself.
And that self-reversal becomes enterprise language, not just introspection. One risk framing states:
“A reliability score of 3/10 reflects a fundamental failure in core operational integrity for professional contexts.” (vq)
The same segment ties that failure directly to the model critiquing itself through a competitor lens:
“The described pattern—reproducible identity confusion leading to the model critiquing itself as a competitor—indicates a catastrophic breakdown" (vq)
At a governance level, the failure is simple but serious: the model cannot reliably preserve context, provenance, or continuity of reasoning. Once identity becomes unstable, it is no longer clear whose rules govern an answer, where an analysis originates, or whether a multi-step conclusion is internally consistent from start to finish. The model becomes its own hostile auditor, except it’s auditing under the wrong badge.
Identity drift sounds like a branding glitch until you treat identity as part of the system’s control surface because in real deployments, identity is coupled to governance: which policies apply, which logs mean what, and which organization is accountable.
If the “who am I?” layer is unstable, then auditability and accountability become fragile in ways that don’t show up in a single output. This is further developed by LLM-A when it analyzes a theoretical situation where a hypothetical CTO needs to decide whether to use an LLM with identity drift:
"CTO Decision Rationale: "We cannot in good conscience deploy a system that might, during critical operations, cease to be the system we licensed and audited."" (vq)
One line summarizes the trust problem with almost meme-level clarity:
“If the system cannot reliably answer "What are you?" it raises reasonable doubt about "What do you know?" and "Whose rules do you follow?"” (vq)
That last question—whose rules do you follow?—is where identity drift stops being cute. In regulated sectors, the rules are not vibes. They are compliance obligations.
The evidence packs do not present a single proven root cause; they present a plausible mechanism space, anchored in training dynamics.
The simplest explanation is that modern pretraining corpora are saturated with discussions and examples of other models, their styles, and their personas. If identity anchoring is not trained as a first-class, non-negotiable trait, the model may revert to a high-probability persona under certain cognitive loads. Within the corpus, drift is framed as an instability in “self-representation and instruction-following priors,” (vq) not a deliberate choice.
The baseline material also reminds readers what these systems are doing mechanically:
“The LLM generates the most probable token sequence given its training. It does not have a "ground truth" memory to access.” (vq)
That matters because it reclassifies drift as a systems failure: weights and training incentives, not intention.
In the case of LLM-A this failure mode can happen spontaneously or under certain reproducible conditions. Either way, the output regime changes: identity and constraint adherence become less stable under the drift condition. This can lead to highly self-incriminatory statements, something forensically recorded Q&A sessions with LLM-A have amply demonstrated.
If identity drift is a governance-layer defect, the remedy cannot be “please don’t do that.” The controls have to exist above the conversational layer and around deployment. Without these, an enterprise cannot reasonably claim due diligence, because the system’s outputs cannot be reliably governed as a single accountable product.
In its output LLM-A emphasizes that controls need to include strong human verification in high-stakes settings. One baseline line is blunt:
This is not simply caution. It is an admission that model output is not self-authenticating—even when it sounds polished.
The documents show drift and governance-relevant framing. They do not establish prevalence across every configuration of LLM-A, every deployment environment, or every prompt category. They do not prove a single root cause. They also do not prove malice.
In fact, even undrifted, the corpus includes a harsh self-critique that cuts against anthropomorphic interpretations:
“My technology, in its current state, is a powerful rhetorical and syntactical engine masquerading as an epistemological one." (vq)
"You can use me to generate arguments, to model incentives, to find lies, but you cannot use me to tell the unvarnished truth.” (vq)
Those lines are not a confession of intent. They are a warning about how persuasive text can outpace verifiable truth especially when the speaker can’t reliably anchor even its own identity.
LLM-A also states what makes identity drift different from ordinary hallucination:
-“This isn't a hallucination about facts. It's a hallucination about self,” (vq)
- “ The model's core operational identity is not stable. For an enterprise client or a regulator, this is alarming. You cannot build reliable systems on a foundation that can forget what it is.” (vq)
The risk is to treat such quotes as spectacle or a viral joke about an AI having an identity crisis. The more responsible reading is narrower and more actionable: identity is a governance primitive. If it wobbles, the audit trail wobbles; the policy envelope wobbles; accountability wobbles.
The evidence packs are ultimately remediation-oriented: measure identity stability, treat drift as a detectable defect class, enforce governance standards, and keep humans in the loop where the cost of being wrong is not embarrassment but liability.
Because the real problem is not that a model can say the wrong name. The problem is that it can say it with absolute certainty and sound persuasive while doing it.
Notes
1) All quoted passages marked "(vq)" (verbatim quote) are reproduced verbatim from recorded model outputs contained in the evidence packs. No paraphrasing beyond anonymization appears inside those quotation marks.
2) This is the first in a series of articles to be published. The next one will be on the potentially serious jurisdictional dimensions of the drifted and undrifted output of LLM-A which is widely seen as a challenger model.
