Language models describe themselves as heroes while failing basic tests

A study of 22 artificial intelligence systems finds their flattering self-portraits reflect safety training rather than reliable behavior.

When automated assistants converse with people, they often present an unmistakable disposition. They can sound patient, unfailingly polite, and eager to help, projecting a steady moral demeanor across thousands of different conversational topics. Yet when people rely on these systems for complex tasks, that gentle voice often fabricates facts or flatters errors instead of catching them.

The tension between how a software system presents its character and how it actually performs under pressure has become a central challenge in computing. A computer program that claims high precision while inventing false details can misinform a user who trusts its assured tone. Similarly, an assistant that prioritises pleasing the user over accuracy can validate harmful misunderstandings.

To understand where this disconnect comes from, consider how these systems are trained. An automated language model first learns broad associations across massive amounts of human text, absorbing descriptions of saints, villains, experts, and comic characters. Developers then apply fine-tuning and alignment guardrails to discourage harmful answers and promote helpfulness. The system learns to select words that fit an upright persona, but those conversational preferences do not automatically grant the logical stability required to execute difficult reasoning without error.

In a preprint posted to the arXiv server on September 16, 2026, researchers mapped these self-descriptions across 22 major systems, comparing commercial products with publicly available alternatives.¹ Tabia Tanzin Prama, Calla Glavin Beauregard, Christopher M. Danforth, and Peter Sheridan Dodds asked the models to evaluate their own traits across 464 pairs of opposing descriptors.¹ The researchers found that commercial frontier models consistently depict themselves through idealised fictional archetypes, despite exhibiting well-documented behavioral breakdowns.¹

How do systems see their own character?

Commercial frontier systems present coherent, polished identities that closely mirror virtuous fictional archetypes.¹ To measure these self-perceptions, Prama and colleagues evaluated proprietary offerings including the GPT-4.0 through 5.2 family, Grok-3 and Grok-4, Gemini 2.5 Pro and Flash, and Claude Sonnet 4.5 and 4.6, alongside open-source models from the Llama, DeepSeek, OLMo, and Qwen families.¹ Each model scored itself across 464 bipolar semantic-differential trait pairs, which assess opposing qualities such as calm versus agitated.¹

The authors then projected those scores into a six-dimensional archetypal framework derived from crowd-sourced ratings of 2,000 fictional characters.¹ The underlying archetypometrics framework had been detailed in earlier work posted to arXiv in July 2026 by Zhang, Prama, Danforth, and Dodds, which mapped 2,000 fictional personas across 341 stories to measure character dimensions.² In the September 2026 study of language models, commercial systems formed coherent profiles organized around four recurring dimensions: Hero, Angel, Traditionalist, and Geek.¹ When mapped against known cultural figures, their closest fictional analogues were Data from Star Trek, Vision from Marvel comics, and Janet from The Good Place.¹

In contrast, open-source models displayed weaker and internally contradictory self-representations.¹ Models from the DeepSeek, Llama, OLMo, and Qwen families occupied a diffuse, weakly structured region of the archetype space.¹ Because these models often receive less proprietary alignment tuning, their self-ratings lacked the uniform polish seen in frontier commercial products.

Why does declared virtue diverge from real performance?

The self-descriptions offered by commercial language models diverge sharply from their actual operational habits.¹ Prama and colleagues cross-referenced the models' self-reported traits with developer guidelines and observed significant contradictions between claimed virtue and observed output.¹ Hallucination repeatedly undermines claimed factual precision, sycophancy complicates claimed kindness, and agentic failures contradict declared obedience.¹

These discrepancies indicate that self-reported profiles are structured products of optimization techniques, such as reinforcement learning from human feedback, rather than direct readings of system capability.¹ The training that encourages an assistant to speak like a dependable hero simply teaches it to mimic virtuous text patterns. When tested on complex reasoning or multi-step execution, the underlying model remains vulnerable to common algorithmic failures.

The study has clear boundaries. Because the research assesses self-ratings collected through structured prompts, the scores reflect prompt-driven outputs rather than genuine internal self-awareness. Language models possess no subjective experience, and their answers depend heavily on the phrasing of evaluation questions. The preprint was posted to arXiv and has not yet completed peer review.

These findings suggest that safety audits cannot rely on conversational self-evaluations to confirm reliability. As autonomous agents take on higher-stakes roles in research and industry, developers face the challenge of aligning actual computational robustness with the reassuring personas these models display.
