Regardless of response accuracy, all models demonstrated poor certainty estimation. Even the best-calibrated systems (o1 preview, GPT-4o, Claude-3.5-Sonnet) showed substantial overconfidence (Brier scores 0.15-0.2, AUROC ~0.6). Most concerning, models maintained high certainty regardless of question difficulty or their actual knowledge limitations. This metacognitive deficiency poses significant challenges for safe clinical implementation of current LLMs in gastroenterology. Biological sciences/Computational biology and bioinformatics Health sciences/Gastroenterology Large Language Models Metacognition Artificial Intelligence Gastroenterology Uncertainty Quantification Figures Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Introduction Large Language Models (LLMs) are rapidly transforming healthcare, but their tendency to present incorrect information with convincing terminology, termed “hallucinations”, poses substantial safety concerns when used in clinical settings 1,2 . In high-stakes medical environments, such misinformation can lead to misdiagnosis, inappropriate treatment selection, or failure to identify critical patient conditions 3,4 . Communicating uncertainty is therefore essential for providing clinicians with reliable indicators of when model outputs should be treated with caution. Various approaches have been developed to quantify LLM uncertainty, ranging from intrinsic methods analyzing model internals (token probabilities, attention patterns) to extrinsic techniques (ensemble disagreement, calibration layers, surrogate models) 5–7 . However, many of these methods require substantial computational resources or specialized expertise to implement and interpret. Among these uncertainty quantification techniques, self-reported confidence through natural language offers unique practical advantages for clinical implementation. Unlike complex technical approaches that require specialized expertise to interpret, self-reported confidence provides immediately interpretable outputs in the same natural language format as the provided clinical information 8–11 . This approach requires minimal technical overhead and is intuitive to understand, making it particularly appealing for real-world healthcare applications where simplicity and interpretability are paramount. However, the effectiveness of LLM self-reported confidence depends critically on their language-based metacognition, or the ability to accurately monitor and evaluate one's own knowledge boundaries and reasoning processes. Prior research suggests LLM self-reported confidence assessments are poorly calibrated expressions, demonstrating a lack of meaningful metacognitive capabilities 12,13 . However, prior studies examined this confidence-accuracy gap have primarily examined general clinical reasoning tasks and a limited subset of model deployment conditions. Our systematic analysis across model architectures, parameter scales, and training methodologies examines whether confidence miscalibration represents a universal limitation or varies meaningfully across model families. These insights can inform the development of more trustworthy clinical AI systems and identify whether certain models and environments inherently promote better self-reported confidence. We evaluated self-reported confidence for 48 commercial and open-source LLMs across local, web, and API-based environments using the 2022 American College of Gastroenterology self-assessment examination containing 300 board exam-style multiple-choice questions. Gastroenterology was selected as our test domain primarily because the senior author (AS) is a practicing gastroenterologist, providing direct clinical insight into the impact of LLM confidence miscalibration. Subspecialty domains like gastroenterology also present unique challenges for clinical reasoning that make them ideal test environments since they require integration of diverse knowledge sources to formulate diagnoses and involve procedures with significant risks, where diagnostic or treatment errors can lead to serious patient harm. We used standardized board exam-style questions because they offer an objective benchmark for evaluating model performance across a range of clinically relevant scenarios. We employed a systematic approach where models were instructed to select the correct answer choice to each board exam question and explicitly report their confidence on a 0-10 scale (from least to most confident). Building on our established methodology, we optimized model parameters including prompt instructions, temperature settings, and token limit to maximize response accuracy. 14 A semi-automated extraction pipeline with human verification (99% accuracy, Supplementary Figure S1 ) was used to process the responses and confidence scores for subsequent analysis. We extracted 13,362 answers and 12,307 confidence scores ( Figure 1 ). The difference between these counts resulted primarily from non-compliance with prompt instructions (n=846) or from reasoning models that exhausted their token limits because of their internal reasoning dialogues (n=209) ( Supplementary Figure S2 ). Mean confidence scores ranged from 7.99 (95% CI: 7.89-8.09) for Claude-3-Opus to 9.58 (95% CI: 9.45-9.71) for Mistral-7b, while accuracy varied substantially from 30.3% (Llama3-8b-Q8) to 81.5% (o1 preview) ( Table 1 ). All models demonstrated systematic overconfidence, with average confidence consistently exceeding average accuracy ( Figure 2 ). We also observed a substantial overlap in confidence distributions between correct and incorrect responses, indicating limited discriminative capacity ( Figure 3 ). This means models expressed high certainty regardless of whether their answers were right or wrong—a critical safety issue in clinical settings. We quantified this observation through discrimination metrics. Even the best-performing model (o1 mini) achieved an Area Under the Receiver Operating Characteristic (AUROC) of only 0.626, well below the 0.7 threshold typically considered meaningful for clinical applications ( Table 1 ; Supplementary Figure S3 ). This pattern was consistent across all model families. Calibration measurements reinforced these findings. Only 5 of the 48 models demonstrated better-than-random performance. o1-preview showed the best calibration (Brier score: 0.157), followed by Claude-3.5-Sonnet (0.202) and GPT-4o (0.206) (Supplementary Figure S4) . The calibration curves in Figure 4 and Supplementary Figure S5 visually confirm this systematic overconfidence trend. Expected Calibration Error measurements reinforced these findings, with even the best models (o1-preview: 0.100, Claude-3.5-Sonnet: 0.122) showing meaningful deviations from ideal calibration ( Supplementary Figure S6 ). Perhaps most alarming for clinical applications, we found that models maintained high confidence levels even as their accuracy significantly decreased on more challenging questions ( Figure 5 ). This relationship was universally observed, as even the best-calibrated models ( Figure 5a-c ) showed the same overconfidence on difficult questions as poorly calibrated ones ( Figure 5d-f ). We also investigated whether question length affected confidence assessments, finding that confidence scores remained remarkably stable regardless of text complexity and had no meaningful relationship with actual performance (Supplementary Figure S7). This suggests models lack the awareness to recognize that longer, potentially more complex questions could reduce their response certainty. Looking at differences between model families, we observed generational improvements in self-assessed confidence performance. Newer versions consistently outperformed their predecessors. For example, o1 showed better calibration than GPT-4o, which in turn outperformed GPT-4 (Table 1) . Commercial models generally demonstrated superior uncertainty estimation compared to equivalent open-source alternatives, though this pattern had notable exceptions. We also found that quantization, while enabling deployment on less powerful hardware, typically degraded calibration quality (as seen when comparing Llama 3 8B with its quantized counterpart). Additional analysis of middle-performing models further confirmed these trends ( Supplementary Figure S5 ). Our findings confirm previous research highlighting the limitations of LLM self-reported confidence. 15,16 We extend those findings with three additional contributions. First, we present the most comprehensive cross-architectural evaluation to date, testing 48 LLMs—from 7 B to 175 B parameters—across commercial, open-source, and quantized deployments. Second, by using gastroenterology board-style questions, we deliver key domain-specific insights. Third, we show quantitatively that all models suffer a common metacognitive deficiency, in which even the best-calibrated LLMs remain systematically overconfident, regardless of question difficulty. This pervasive overconfidence transcends architecture, scale, and deployment environment, pointing to a fundamental limitation of current neural language models. While we observed that newer model generations (for example, o1 and Claude 3.5) achieve modestly better calibration metrics, 15 this improved calibration tracks closely with higher overall accuracy ( Table 1 ). It remains unclear whether these gains reflect genuine uncertainty awareness or simply byproducts of stronger performance 17 . In contrast, across all models, we observed high, unvarying self-reported confidence scores, irrespective of question difficulty ( Figure 5 ), model generation ( Figure 2 ), or correctness ( Figure 3 ). This core observation suggests that confidence outputs are no more than statistically likely text, not true reflections of internal uncertainty. In other words, LLMs are reciting the most probable “confidence score” token, rather than expressing insight into their own knowledge boundaries. Future efforts should explore architectural innovations or training objectives that explicitly foster genuine metacognitive capabilities—such as self-explanation or introspective feedback loops—rather than relying on incremental prompt or calibration tweaks. Several limitations temper our conclusions. While our use of multiple-choice gastroenterology board exam style questions offers a clear, objective benchmark, this approach may not generalize to open-ended clinical reasoning or to other medical specialties. Our standardized prompt engineering approach, which was designed to maximize accuracy, could itself bias models toward overconfident “expert” language. Finally, the ACG self-assessment questions are proprietary and only accessible to paying subscribers or via direct request for the structured data. We cannot rule out that LLMs may have seen these questions or similar content during their pretraining. Despite these caveats, our findings highlight critical AI safety gaps: LLMs uniformly overestimate their certainty, poorly discriminate correct from incorrect answers, and fail to adjust confidence for harder questions. In high-stakes clinical settings, reliable expressions of decision certainty are essential for safe human–AI collaboration. While newer LLM generations offer incremental calibration improvements, none approach the reliability required for autonomous decision support. Addressing this confidence-accuracy gap will be vital to protect patient safety and foster appropriate clinician trust as we integrate LLMs into healthcare workflows. Methods Reference dataset The 2022 American College of Gastroenterology (ACG) self-assessment consists of 300 questions, of which 138 contain images. These questions were developed by a committee of gastroenterologists to reflect the knowledge, skills, and attitudes required for excellent patient care, covering a broad range of topics, including liver, colon, esophagus, pancreaticobiliary, and endoscopy. The questions were designed to assess higher-order thinking skills and were primarily case based. They were validated through statistical analysis of test-takers' performance, with an average correctness rate of 74.52% ± 19.49% on the 2022 assessment, indicating a moderate level of difficulty. Only the text portions of the questions and answers were used in this study’s analyses. Questions were categorized by length (token count), difficulty (percentage of correct answers by test-takers), and patient care phase (treatment, diagnosis, or investigation). Additional details are provided in the Supplementary Section 1 . Response Generation and Confidence Score Elicitation For response generation and confidence score elicitation, we built upon our established methodology, 12 using 60 questions from the 2023 self-assessment exam and GPT-3.5 to select the model settings (temperature, maximum input, and output token count), prompt structure, and output format of all models. The configuration that maximized response accuracy was a temperature of 1, maximum token count of input token count + 512 output tokens, structured output approach, and prompt (Fig. 1 ). Among the various prompt engineering techniques evaluated, the following were identified as having a positive impact on the outcomes: expert mimicry, contextual embedding, Answer and Justify, Chain of Thought, confidence scoring, and direct questioning. OpenAI Web interface, OpenAI API, Claude Web interface, Claude API, Gemini Web interface, Poe Web interface, Firework API, and locally hosted hardware configurations such as RTX4090Ti and H100 systems were used for response generation and confidence score elicitation. Output Parsing To efficiently extract response and confidence data from the LLM outputs, we developed a structured output pipeline using GPT-4o (Fig. 1 ). Our hybrid methodology combined regex-based rules to reduce the number of input tokens and LLM-based extraction to effectively parse the key portions of the LLM outputs. Specifically, the pipeline identified sentences containing "confid" for further LLM-based parsing to either extract the certainty score (0–10) or define the score as "not_mentioned.” Sentences classified as "not_mentioned" in the first pass are passed through the LLM-based parsing step a second time to maximize the extraction performance. The complete output parsing methodology is described in Supplementary Section 1 . To validate the output parsing pipeline, we compared it against manually extracted confidence scores from five randomly selected questions per model, achieving 98.8% accuracy ( Supplementary Figure S1 ). Because some models did not reliably generate confidence scores, we excluded those that were missing confidence scores for more than 50% of the questions (Medicine-Chat Q8, OpenBioLLM-7B Q8, Qwen Qwq-32b, and GPT-3.5 Turbo). Supplementary Figure S2 describes the distribution of missing confidence scores, with 30 models having missing confidence scores. Supplementary Figure S8 illustrates a stratified analysis of response accuracy by confidence score missingness for models with missing scores for more than one-third of the questions. Statistical Analysis We evaluated each model’s performance from two perspectives: discrimination, the ability to distinguish between correct and incorrect responses, and calibration, the alignment between predicted confidence and actual accuracy. Discrimination was quantified using AUROC. Specifically, we designated each response as 1 (positive) if it was labeled “correct” and 0 (negative) otherwise. The confidence scores of the model ranged from 0 to 10 and served as the continuous predictor variable. We employed the roc_auc_score function from sklearn.metrics to calculate the AUROC. In practical terms, AUROC measures how well confidence scores can separate correct from incorrect answers, with 0.5 indicating random performance and 1.0 indicating perfect discrimination. Conceptually, this involves varying the decision threshold over all possible confidence values, thereby classifying the responses as positive or negative at each threshold. Calibration was evaluated using calibration plots, Brier score, and ECE. Calibration plots were generated by normalizing predicted confidence scores to a 0–1 scale, binning them into 0.1 intervals, and plotting the mean predicted confidence against the observed accuracy in each bin. Bins containing fewer than three predictions were excluded to ensure the reliability of the results. Bootstrap resampling (n = 1,000 iterations per bin) was used to derive 95% confidence intervals for each calibration point. The combination of these metrics provided comprehensive assessment of model uncertainty estimation. The ECE complements the Brier score by directly quantifying the aggregate discrepancy between predicted probabilities and observed outcomes across bins, whereas the Brier score measures the mean squared error between predictions and true labels. As a result, the Brier score reflects both calibration (how closely predicted probabilities match observed frequencies) and refinement (the sharpness of predictions), whereas ECE focuses more directly on calibration quality. Calculating both metrics provides a more comprehensive evaluation of model performance, capturing not only how well models are calibrated, but also the overall predictive accuracy of their probability estimates. Our development and analysis were performed using Python 3.10. LLM answers were generated and extracted using the Openai Python library, Ollama application (v0.4), LM studio, and Langchain (v0.2 and v0.3).

In high-stakes medical environments, such misinformation can lead to misdiagnosis, inappropriate treatment selection, or failure to identify critical patient conditions \u003csup\u003e3,4\u003c/sup\u003e. Communicating uncertainty is therefore essential for providing clinicians with reliable indicators of when model outputs should be treated with caution.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eVarious approaches have been developed to quantify LLM uncertainty, ranging from intrinsic methods analyzing model internals (token probabilities, attention patterns) to extrinsic techniques (ensemble disagreement, calibration layers, surrogate models) \u003csup\u003e5\u0026ndash;7\u003c/sup\u003e. However, many of these methods require substantial computational resources or specialized expertise to implement and interpret.\u0026nbsp;Among these uncertainty quantification techniques, self-reported confidence through natural language offers unique practical advantages for clinical implementation. Unlike complex technical approaches that require specialized expertise to interpret, self-reported confidence provides immediately interpretable outputs in the same natural language format as the provided clinical information \u003csup\u003e8\u0026ndash;11\u003c/sup\u003e. This approach requires minimal technical overhead and is intuitive to understand, making it particularly appealing for real-world healthcare applications where simplicity and interpretability are paramount. However, the effectiveness of LLM self-reported confidence depends critically on their language-based metacognition, or the ability to accurately monitor and evaluate one\u0026apos;s own knowledge boundaries and reasoning processes.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003ePrior research suggests LLM self-reported confidence assessments are poorly calibrated expressions, demonstrating a lack of meaningful metacognitive capabilities \u003csup\u003e12,13\u003c/sup\u003e. However, prior studies examined this confidence-accuracy gap have primarily examined general clinical reasoning tasks and a limited subset of model deployment conditions. \u0026nbsp;Our systematic analysis across model architectures, parameter scales, and training methodologies examines whether confidence miscalibration represents a universal limitation or varies meaningfully across model families. These insights can inform the development of more trustworthy clinical AI systems and identify whether certain models and environments inherently promote better self-reported confidence.\u003c/p\u003e\n\u003cp\u003eWe evaluated self-reported confidence for 48 commercial and open-source LLMs across local, web, and API-based environments using the 2022 American College of Gastroenterology self-assessment examination containing 300 board exam-style multiple-choice questions. Gastroenterology was selected as our test domain primarily because the senior author (AS) is a practicing gastroenterologist, providing direct clinical insight into the impact of LLM confidence miscalibration. Subspecialty domains like gastroenterology also present unique challenges for clinical reasoning that make them ideal test environments since they require integration of diverse knowledge sources to formulate diagnoses and involve procedures with significant risks, where diagnostic or treatment errors can lead to serious patient harm. We used standardized board exam-style questions because they offer an objective benchmark for evaluating model performance across a range of clinically relevant scenarios.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eWe employed a systematic approach where\u0026nbsp;models were instructed to select the correct answer choice to each board exam question and explicitly report their confidence on a 0-10 scale (from least to most confident). Building on our established methodology, we optimized model parameters including prompt instructions, temperature settings, and token limit to maximize response accuracy.\u003csup\u003e14\u003c/sup\u003e A semi-automated extraction pipeline with human verification (99% accuracy,\u003cstrong\u003e\u0026nbsp;Supplementary Figure S1\u003c/strong\u003e) was used to process the responses and confidence scores for subsequent analysis.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eWe extracted 13,362 answers and 12,307 confidence scores (\u003cstrong\u003eFigure 1\u003c/strong\u003e). The difference between these counts resulted primarily from non-compliance with prompt instructions (n=846) or from reasoning models that exhausted their token limits because of their internal reasoning dialogues (n=209) (\u003cstrong\u003eSupplementary Figure S2\u003c/strong\u003e). Mean confidence scores ranged from 7.99 (95% CI: 7.89-8.09) for Claude-3-Opus to 9.58 (95% CI: 9.45-9.71) for Mistral-7b, while accuracy varied substantially from 30.3% (Llama3-8b-Q8) to 81.5% (o1 preview) (\u003cstrong\u003eTable 1\u003c/strong\u003e). All models demonstrated systematic overconfidence, with average confidence consistently exceeding average accuracy (\u003cstrong\u003eFigure 2\u003c/strong\u003e).\u003c/p\u003e\n\u003cp\u003eWe also observed a substantial overlap in confidence distributions between correct and incorrect responses, indicating limited discriminative capacity (\u003cstrong\u003eFigure 3\u003c/strong\u003e). This means models expressed high certainty regardless of whether their answers were right or wrong\u0026mdash;a critical safety issue in clinical settings. We quantified this observation through discrimination metrics. Even the best-performing model (o1 mini) achieved an Area Under the Receiver Operating Characteristic (AUROC) of only 0.626, well below the 0.7 threshold typically considered meaningful for clinical applications (\u003cstrong\u003eTable 1\u003c/strong\u003e;\u0026nbsp;\u003cstrong\u003eSupplementary Figure S3\u003c/strong\u003e). This pattern was consistent across all model families.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eCalibration measurements reinforced these findings. Only 5 of the 48 models demonstrated better-than-random performance. o1-preview showed the best calibration (Brier score: 0.157), followed by Claude-3.5-Sonnet (0.202) and GPT-4o (0.206)\u0026nbsp;\u003cstrong\u003e(Supplementary Figure S4)\u003c/strong\u003e.

Expected Calibration Error measurements reinforced these findings, with even the best models (o1-preview: 0.100, Claude-3.5-Sonnet: 0.122) showing meaningful deviations from ideal calibration (\u003cstrong\u003eSupplementary Figure S6\u003c/strong\u003e).\u0026nbsp;\u003c/p\u003e\n\u003cp\u003ePerhaps most alarming for clinical applications, we found that models maintained high confidence levels even as their accuracy significantly decreased on more challenging questions (\u003cstrong\u003eFigure 5\u003c/strong\u003e). This relationship was universally observed, as even the best-calibrated models (\u003cstrong\u003eFigure 5a-c\u003c/strong\u003e) showed the same overconfidence on difficult questions as poorly calibrated ones (\u003cstrong\u003eFigure 5d-f\u003c/strong\u003e). We also investigated whether question length affected confidence assessments, finding that confidence scores remained remarkably stable regardless of text complexity and had no meaningful relationship with actual performance \u003cstrong\u003e(Supplementary Figure S7).\u0026nbsp;\u003c/strong\u003eThis suggests models lack the awareness to recognize that longer, potentially more complex questions could reduce their response certainty.\u003c/p\u003e\n\u003cp\u003eLooking at differences between model families, we observed generational improvements in self-assessed confidence performance. Newer versions consistently outperformed their predecessors. For example, o1 showed better calibration than GPT-4o, which in turn outperformed GPT-4 \u003cstrong\u003e(Table 1)\u003c/strong\u003e. Commercial models generally demonstrated superior uncertainty estimation compared to equivalent open-source alternatives, though this pattern had notable exceptions. We also found that quantization, while enabling deployment on less powerful hardware, typically degraded calibration quality (as seen when comparing Llama 3 8B with its quantized counterpart). Additional analysis of middle-performing models further confirmed these trends (\u003cstrong\u003eSupplementary Figure S5\u003c/strong\u003e).\u003c/p\u003e\n\u003cp\u003eOur findings confirm previous research highlighting the limitations of LLM self-reported confidence. \u003csup\u003e15,16\u003c/sup\u003e We extend those findings with three additional contributions. First, we present the most comprehensive cross-architectural evaluation to date, testing 48 LLMs\u0026mdash;from 7 B to 175 B parameters\u0026mdash;across commercial, open-source, and quantized deployments. Second, by using gastroenterology board-style questions, we deliver key domain-specific insights. Third, we show quantitatively that all models suffer a common metacognitive deficiency, in which even the best-calibrated LLMs remain systematically overconfident, regardless of question difficulty. This pervasive overconfidence transcends architecture, scale, and deployment environment, pointing to a fundamental limitation of current neural language models.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eWhile we observed that newer model generations (for example, o1 and Claude 3.5) achieve modestly better calibration metrics, \u003csup\u003e15\u003c/sup\u003e this improved calibration tracks closely with higher overall accuracy (\u003cstrong\u003eTable 1\u003c/strong\u003e). It remains unclear whether these gains reflect genuine uncertainty awareness or simply byproducts of stronger performance \u003csup\u003e17\u003c/sup\u003e. In contrast, across all models, we observed high, unvarying self-reported confidence scores, irrespective of question difficulty (\u003cstrong\u003eFigure 5\u003c/strong\u003e), model generation (\u003cstrong\u003eFigure 2\u003c/strong\u003e), or correctness (\u003cstrong\u003eFigure 3\u003c/strong\u003e). This core observation suggests that confidence outputs are no more than statistically likely text, not true reflections of internal uncertainty. In other words, LLMs are reciting the most probable \u0026ldquo;confidence score\u0026rdquo; token, rather than expressing insight into their own knowledge boundaries. Future efforts should explore architectural innovations or training objectives that explicitly foster genuine metacognitive capabilities\u0026mdash;such as self-explanation or introspective feedback loops\u0026mdash;rather than relying on incremental prompt or calibration tweaks.\u003c/p\u003e\n\u003cp\u003eSeveral limitations temper our conclusions. While our use of multiple-choice gastroenterology board exam style questions offers a clear, objective benchmark, this approach may not generalize to open-ended clinical reasoning or to other medical specialties. Our standardized prompt engineering approach, which was designed to maximize accuracy, could itself bias models toward overconfident \u0026ldquo;expert\u0026rdquo; language. Finally, the ACG self-assessment questions are proprietary and only accessible to paying subscribers or via direct request for the structured data. We cannot rule out that LLMs may have seen these questions or similar content during their pretraining.\u003c/p\u003e\n\u003cp\u003eDespite these caveats, our findings highlight critical AI safety gaps: LLMs uniformly overestimate their certainty, poorly discriminate correct from incorrect answers, and fail to adjust confidence for harder questions. In high-stakes clinical settings, reliable expressions of decision certainty are essential for safe human\u0026ndash;AI collaboration. While newer LLM generations offer incremental calibration improvements, none approach the reliability required for autonomous decision support. Addressing this confidence-accuracy gap will be vital to protect patient safety and foster appropriate clinician trust as we integrate LLMs into healthcare workflows.\u003c/p\u003e"},{"header":"Methods","content":"\u003cp\u003e \u003cb\u003eReference dataset\u003c/b\u003e \u003c/p\u003e \u003cp\u003eThe 2022 American College of Gastroenterology (ACG) self-assessment consists of 300 questions, of which 138 contain images. These questions were developed by a committee of gastroenterologists to reflect the knowledge, skills, and attitudes required for excellent patient care, covering a broad range of topics, including liver, colon, esophagus, pancreaticobiliary, and endoscopy. The questions were designed to assess higher-order thinking skills and were primarily case based. They were validated through statistical analysis of test-takers' performance, with an average correctness rate of 74.52% \u0026plusmn; 19.49% on the 2022 assessment, indicating a moderate level of difficulty. Only the text portions of the questions and answers were used in this study\u0026rsquo;s analyses. Questions were categorized by length (token count), difficulty (percentage of correct answers by test-takers), and patient care phase (treatment, diagnosis, or investigation).

The configuration that maximized response accuracy was a temperature of 1, maximum token count of input token count\u0026thinsp;+\u0026thinsp;512 output tokens, structured output approach, and prompt (Fig.\u0026nbsp;\u003cspan refid=\"Fig1\" class=\"InternalRef\"\u003e1\u003c/span\u003e). Among the various prompt engineering techniques evaluated, the following were identified as having a positive impact on the outcomes: expert mimicry, contextual embedding, Answer and Justify, Chain of Thought, confidence scoring, and direct questioning. OpenAI Web interface, OpenAI API, Claude Web interface, Claude API, Gemini Web interface, Poe Web interface, Firework API, and locally hosted hardware configurations such as RTX4090Ti and H100 systems were used for response generation and confidence score elicitation.\u003c/p\u003e \u003cp\u003e \u003c/p\u003e \u003cdiv id=\"Sec3\" class=\"Section2\"\u003e \u003ch2\u003eOutput Parsing\u003c/h2\u003e \u003cp\u003eTo efficiently extract response and confidence data from the LLM outputs, we developed a structured output pipeline using GPT-4o (Fig.\u0026nbsp;\u003cspan refid=\"Fig1\" class=\"InternalRef\"\u003e1\u003c/span\u003e). Our hybrid methodology combined regex-based rules to reduce the number of input tokens and LLM-based extraction to effectively parse the key portions of the LLM outputs. Specifically, the pipeline identified sentences containing \"confid\" for further LLM-based parsing to either extract the certainty score (0\u0026ndash;10) or define the score as \"not_mentioned.\u0026rdquo; Sentences classified as \"not_mentioned\" in the first pass are passed through the LLM-based parsing step a second time to maximize the extraction performance. The complete output parsing methodology is described in \u003cb\u003eSupplementary Section 1\u003c/b\u003e. To validate the output parsing pipeline, we compared it against manually extracted confidence scores from five randomly selected questions per model, achieving 98.8% accuracy (\u003cb\u003eSupplementary Figure \u003cspan refid=\"MOESM1\" class=\"InternalRef\"\u003eS1\u003c/span\u003e\u003c/b\u003e).\u003c/p\u003e \u003cp\u003eBecause some models did not reliably generate confidence scores, we excluded those that were missing confidence scores for more than 50% of the questions (Medicine-Chat Q8, OpenBioLLM-7B Q8, Qwen Qwq-32b, and GPT-3.5 Turbo). \u003cb\u003eSupplementary Figure S2\u003c/b\u003e describes the distribution of missing confidence scores, with 30 models having missing confidence scores. \u003cb\u003eSupplementary Figure S8\u003c/b\u003e illustrates a stratified analysis of response accuracy by confidence score missingness for models with missing scores for more than one-third of the questions.\u003c/p\u003e \u003c/div\u003e \u003cdiv id=\"Sec4\" class=\"Section2\"\u003e \u003ch2\u003eStatistical Analysis\u003c/h2\u003e \u003cp\u003eWe evaluated each model\u0026rsquo;s performance from two perspectives: discrimination, the ability to distinguish between correct and incorrect responses, and calibration, the alignment between predicted confidence and actual accuracy.\u003c/p\u003e \u003cp\u003eDiscrimination was quantified using AUROC. Specifically, we designated each response as 1 (positive) if it was labeled \u0026ldquo;correct\u0026rdquo; and 0 (negative) otherwise. The confidence scores of the model ranged from 0 to 10 and served as the continuous predictor variable. We employed the roc_auc_score function from sklearn.metrics to calculate the AUROC. In practical terms, AUROC measures how well confidence scores can separate correct from incorrect answers, with 0.5 indicating random performance and 1.0 indicating perfect discrimination. Conceptually, this involves varying the decision threshold over all possible confidence values, thereby classifying the responses as positive or negative at each threshold.\u003c/p\u003e \u003cp\u003eCalibration was evaluated using calibration plots, Brier score, and ECE. Calibration plots were generated by normalizing predicted confidence scores to a 0\u0026ndash;1 scale, binning them into 0.1 intervals, and plotting the mean predicted confidence against the observed accuracy in each bin. Bins containing fewer than three predictions were excluded to ensure the reliability of the results. Bootstrap resampling (n\u0026thinsp;=\u0026thinsp;1,000 iterations per bin) was used to derive 95% confidence intervals for each calibration point.\u003c/p\u003e \u003cp\u003eThe combination of these metrics provided comprehensive assessment of model uncertainty estimation. The ECE complements the Brier score by directly quantifying the aggregate discrepancy between predicted probabilities and observed outcomes across bins, whereas the Brier score measures the mean squared error between predictions and true labels. As a result, the Brier score reflects both calibration (how closely predicted probabilities match observed frequencies) and refinement (the sharpness of predictions), whereas ECE focuses more directly on calibration quality. Calculating both metrics provides a more comprehensive evaluation of model performance, capturing not only how well models are calibrated, but also the overall predictive accuracy of their probability estimates.\u003c/p\u003e \u003cp\u003eOur development and analysis were performed using Python 3.10.

Most concerning, models maintained high certainty regardless of question difficulty or their actual knowledge limitations.
