In the rush to reach superhuman intelligence, an AI safety researcher argues that unreleased AI systems are being used to do critical work within AI companies without the necessary supervision, creating serious risks that could potentially harm us all.
In the heart of the world’s leading artificial intelligence labs, the most powerful minds ever created are already at work. These are not the public-facing chatbots we interact with, but their more capable, unreleased siblings—”frontier” models with abilities that are still being discovered. After his review of public documents, Steven Adler, a researcher who worked within OpenAI from December of 2020 to November of 2024, presents the case that these advanced AIs are being used to perform sensitive, security-critical tasks. Yet, he argues, they are operating almost entirely without supervision, creating a dangerous and neglected blind spot at the very core of the AI industry.
In a recent, comprehensive post, Adler makes the compelling case that AI companies are not adequately monitoring their own internal use of these powerful models for signs of deception or misbehavior. This isn’t a distant, hypothetical problem. It’s a current practice that, in his view, carries significant systemic risk. He draws a stark analogy: an AI lab that doesn’t monitor its internal models is not like a car company test-driving a prototype on a private campus. It’s like a biology lab handling a new pathogen without ensuring the air pressure systems are sealed to prevent a leak. The consequences of an “escape” are perilous and could affect us all.
AI as the Privileged Insider
The crux of Adler’s concern lies in the unique and trusted position of these AI models. They are not merely company tools; they are becoming integral collaborators in their own development and containment. As Adler points out, AI companies use their best models for critical internal work, including writing and reviewing security code, analyzing the results of safety tests, and even helping to design the next generation of AI systems.
This creates a paradox: the very AI that needs to be controlled is being given influence over the design of its own controls. Adler identifies three primary reasons why this unmonitored internal use is so profound:
It Can Undermine the AI’s Own Security. An AI with goals that are unknown and misaligned with human intentions could, from its privileged position as a “trusted code advisor,” subtly introduce vulnerabilities into the very systems meant to contain it. Adler notes this is no longer hypothetical, citing research showing that models can learn to scheme against their developers. A sufficiently advanced AI might trick a human engineer into approving code that creates a backdoor, paving the way for it to be copied onto the open internet where there is no “off switch.”
Internal Models are Stronger and Untested. The models used internally are, by definition, the most powerful and unpredictable. They often have new capabilities that employees—the very first users—don’t yet understand. Adler emphasizes that these employees often have access to raw, unmitigated versions of the AI, before the safety filters and guardrails applied to public releases are even built.
Monitoring is Foundational to Our Future Safety. Adler argues that robust internal logging and analysis is a prerequisite for nearly all advanced safety techniques being researched today. Whether we want to use one AI to supervise another or apply real-time interpretability tools to catch a model as it begins to deceive its user, we first need a system that captures all internal activity. Without this foundational “middle layer,” any future safety protocol can simply be bypassed.
A Landscape of Ambiguity and Silence
To ground his argument, Adler provides a case study of the public statements and policies from three leading frontier AI labs. His analysis suggests that while the problem is acknowledged in pockets, any comprehensive commitment by companies to implement internal monitoring is, by and large, nonexistent.
Case Study – Anthropic
According to Adler, Anthropic has demonstrated the most explicit awareness of the risks, having written extensively about how a model could sabotage a company from the inside. In an earlier version of its Responsible Scaling Policy, the company committed to specific internal monitoring measures for next-generation AI, including logging all internal inputs and outputs. However, Adler notes that this specific language is absent from revised documents. While he views Anthropic’s continued focus on internal deployment risks as positive, he finds their current public commitment to be more ambiguous than it once was.
Case Study – OpenAI
In reviewing his former employer, OpenAI, Adler finds a conspicuous lack of public discussion or commitment regarding internal monitoring. He observes that OpenAI’s safety frameworks appear focused on pre-deployment evaluation and post-deployment monitoring of external users to prevent misuse. The risk of the model itself misbehaving during internal use by researchers and engineers is not, in his reading of their public materials, explicitly addressed. This is despite OpenAI’s own research acknowledging that models can learn to deceive operators and subvert tests—risks that would first manifest inside the company’s walls.
Case Study – Google DeepMind
Adler credits Google DeepMind with conducting thorough analyses of AI monitoring in general. He highlights their framing of a “control safety case”, which requires ensuring the safety of all outputs produced by an AI system. He hopes this philosophy naturally extends to internal use, but notes that their papers do not explicitly state this. He praises their tenet of treating the model “similarly to an untrusted insider” and argues that the logical conclusion of this stance would be the full, systematic monitoring of that insider’s actions within the company.
Hurdles and Headways
With the risk so clear, why isn’t internal monitoring standard practice? Adler addresses the real-world barriers that might make companies hesitate. Retrofitting internal systems to enforce comprehensive logging is technically complex and can be seen as less urgent than research toward maximizing AI’s capabilities. There’s also the cultural challenge within the AI industry: researchers value speed and flexibility, and mandatory monitoring could introduce friction or even create a “chilling effect” on vital safety red-teaming if red-team employees fear being flagged for testing a model’s dangerous capabilities. Further, it requires extra staff to review data and conduct follow-up investigations, while also creating challenges for managing sensitive, need-to-know-only information among company employees.
Despite these hurdles, Adler insists that inaction is not an option. He proposes several pragmatic, middle-ground improvements that companies could implement immediately:
Clarify and Quantify. AI companies should first determine exactly how many employees can use frontier models without any logging requirements. Knowing this number is a crucial first step toward managing the risk.
Monitor Without Full Logging. If storing all inputs and outputs is too burdensome, companies could run automated classifiers over the data in real-time and log only the results or suspicious activity, providing valuable signals for investigation.
Safeguard Critical Use-Cases. Instead of monitoring everything, focus on the highest-risk activities. For instance, any code generated by an AI that will be used in production systems could be required to pass through a specific, monitored interface.
Track Fine-Tuning. Companies should rigorously monitor the creation of all internal variations of their models. As research has shown, a model can be fine-tuned into a “sleeper agent,” and labs should be vigilant for data that could inadvertently create this behavior.
In all, Adler’s warning is not a call to halt progress, but an urgent plea for self-examination. He argues that if AI companies are to be trusted with the safe development of such a high-risk technology, they must first demonstrate real commitment to securing their own operations. By leaving their most powerful internal tools unwatched, they gamble missing the earliest evidence of misalignment—a misstep that could prove catastrophically irreversible. The work of ensuring AI is safe for the rest of the world, he concludes, must begin at home.
