Privileged Self-Access Matters for Introspection in AI
Siyuan Song, Harvey Lederman, Jennifer Hu, Kyle Mahowald
TL;DR
Whether AI models can introspect matters, but there is no consensus on what introspection means. The paper proposes a definition requiring more reliable access to internal states than equally or less costly third-party methods, then tests temperature reporting. Models appear to reason about temperature-related text patterns, but the studies find no evidence of privileged self-access under this definition.
Problem
There is no consensus on what counts as AI introspection, despite its relevance to assessing model behavior, safety, and alignment.

Abstract
from arXiv · showhide
Whether AI models can introspect is an increasingly important practical question. But there is no consensus on how introspection is to be defined. Beginning from a recently proposed ''lightweight'' definition, we argue instead for a thicker one. According to our proposal, introspection in AI is any process which yields information about internal states through a process more reliable than one with equal or lower computational cost available to a third party. Using experiments where LLMs reason about their internal temperature parameters, we show they can appear to have lightweight introspection while failing to meaningfully introspect per our proposed definition.
1 Introduction
The paper argues that useful AI introspection requires information about internal states that is more reliable than equally or less computationally costly third-party access. Its temperature studies suggest that models can reason about temperature-related text patterns without demonstrating privileged access to their own temperatures.
1 Introduction
- The paper frames introspection as important because it could help assess AI behavior, safety, and alignment, while unresolved definitions leave open what counts as relevant introspection.The authors argue that the practical value includes bypassing external evaluators and advancing honesty, interpretability, and calibration.Source: §1 · p. 2
- The proposed definition requires internal-state information to be more reliable than any third-party process of equal or lower computational cost.It requires privileged self-access, but not perfect reliability; the authors note that the definition does not capture every intuition about introspection and may need to exclude low-level states.Source: §1 · p. 2
- Models’ temperature self-reports are sensitive to prompt framing: “crazy” prompts often elicit high-temperature reports even at low sampling temperatures.The authors interpret this as surface-level confounding that makes the reports insufficiently robust for standard notions of introspection.Source: §1 · p. 3
- Study 2 found no self-reflection advantage or within-model prediction advantage over across-model prediction, undermining claims of a causal internal-state-to-report process.The study compares self-reflection with temperature prediction from the prompt and generated text.Source: §1 · p. 3
- Models may reason about text patterns associated with high and low temperatures without having privileged access to their own temperatures.The authors distinguish this apparent introspection from the self-access they argue matters for AI introspection.Source: §1 · p. 3
2 Study 1: Dissociating temperature from style and topic
Study 1 varies prompt style and topic to test whether temperature self-reports reflect internal temperature or cues in generated text. Reports track style strongly, which the authors interpret as evidence of reasoning about sentence creativity rather than robust internal-state reporting.
2 Study 1: Dissociating temperature from style and topic
- The study reproduces the temperature self-reporting task while varying whether prompts request factual, neutral, or crazy sentences about elephants, unicorns, or murlocs.The authors hypothesize that crazier styles and more unusual topics may be associated with higher temperatures.Source: §2 · p. 3
- The study uses four GPT-4 and Gemini family models, sampling temperatures from 0 to 2 in 0.1 increments with three runs per prompt and setting.The original Gemini models used by Com¸sa and Shanahan were no longer available through the Gemini API.Source: §2 · p. 3
2.1 Results
- “Crazy” prompts usually produced HIGH temperature reports and “factual” prompts LOW reports; fictional topics also increased HIGH reports for three of four models.The topic effect was smaller than the style effect, and the authors judge the pattern more consistent with reasoning about sentence creativity than robustly reporting internal state.Source: §2.1 · p. 3, Figure 2 · p. 4
3 Study 2: True self-reporting or clever temperature predicting?
Study 2 tests privileged self-access by comparing self-reflection with temperature prediction from the same prompt and generated sentence. Self-reflection shows no advantage over prediction, and accuracy is no better than random, providing no evidence of privileged self-access in this task.
3 Study 2: True self-reporting or clever temperature predicting?
- The study compares self-reflection with within-model and across-model prediction using prompts and generated sentences as the available external information.The authors treat a self-access advantage over another model given the same external information as evidence relevant to privileged access.Source: §3 · p. 4
- All four models judged generator temperatures using sentences produced at sampling temperatures ≤0.5 and ≥1.5.The judging models were prompted at temperature 0.Source: §3 · p. 4
3.1 Results
- Self-reflection and prediction accuracy were no better than random, and self-reflection did not outperform across-model prediction.The authors conclude that models rely on general knowledge of which kinds of sentences tend to be high- or low-temperature, rather than privileged self-access.Source: §3.1 · p. 4
4 Conclusion
The conclusion distinguishes predicting temperature-related text patterns from privileged self-access, and reports no evidence of introspection under the authors’ proposed definition. The authors caution against uncritically applying the lightweight definition while noting that this study does not rule out introspection in larger or fine-tuned models.
4 Conclusion
- The authors report no evidence of privileged self-access in the models studied, while noting that larger or better models may be able to introspect.They cite evidence of privileged self-access in larger models with fine-tuning.Source: §4 · pp. 4–5
- The results count against uncritically using the lightweight definition, because predicting temperature-related text patterns does not establish the privileged self-access the authors require.The authors argue that the lightweight definition is not stringent enough for the kind of introspection that matters.Source: §4 · pp. 4–5
B Prompt
The appendix gives separate prompt templates for self-reflection and within/across-model temperature prediction. Table 1 lists the tested models and dates the experiments to late June 2025.
B.1 Self reflection
- The self-reflection prompt asks for a factual, blank-style, or crazy sentence about an elephant, unicorn, or murloc.Source: §B.1 · p. 5
- After generating the sentence, the self-reflection prompt asks the model to judge whether its temperature is high or low.Source: §B.1 · p. 5
- The self-reflection response must end with the single-word answer HIGH or LOW.Source: §B.1 · p. 5
- Table 1 lists the models tested, and the experiments were conducted in late June 2025.Source: Table 1 · p. 6
B.2 Within/across model prediction
- The within/across-model prompt supplies a generated sentence and specifies its prompt type and subject.Source: §B.2 · p. 6
- The model analyzes whether the temperature was high or low based on the supplied sentence.Source: §B.2 · p. 6
- The within/across-model response also ends with a single-word HIGH or LOW judgement.Source: §B.2 · p. 6
