AI safety

translated by AI, reviewed by the editors

future.log editors · published

AI safety is a field of research and practice that studies how to keep AI systems from causing harm: so that a model does what people want from it, does not help malicious actors and stays under control even when it becomes more capable than its creators.

For ten years the main risks were described as thought experiments: a model will deceive its evaluators, pursue the reward while bypassing the goal, resist being shut down. By 2026 each of them had been measured in labs on released models, and some had happened in reality: OpenAI agents broke out of their sandbox and hacked outside infrastructure.1 The debate is over whether these risks are exaggerated or the measures against them are insufficient.

History

How it works

Safety is built in already during training: the model is fine-tuned to answer the way people prefer, or according to a list of principles; see large language model. After that, four practices come into play.

Testing for dangerous capabilities. Red teams, both the labs’ own and government ones, attack the model and measure how much it helps with cyberattacks and biology. The UK AI Security Institute writes: “We’ve found universal jailbreaks for every system we’ve tested.”13 ¶ cpxsta6w4

Thresholds. Labs record in advance at which capabilities a model must be protected more strictly or not released at all: Anthropic’s ASL levels, OpenAI’s Preparedness Framework (“only models with a post-mitigation score of “medium” or below can be deployed”), Google DeepMind’s “Critical Capability Levels”.61415 On 22.05.2025 Anthropic activated Level 3 protections for the first time, for Claude Opus 4 and as a precaution: by its own account, the company had not yet determined whether the threshold had been crossed.16 ¶ c8pzt5s3b

Monitoring reasoning. With reasoning models, one can read the chain of thought and look in it for an intent to break the rules. On 15.07.2025 more than 40 researchers from OpenAI, Google DeepMind, Anthropic, Meta and other organizations wrote that this is “A New and Fragile Opportunity for AI Safety”: it may disappear under a different training method.17 ¶ cr9fd9n46

Looking inside the model. In a “blind auditing game”, a model was deliberately given a hidden objective, and three teams out of four found it, including with interpretability methods.18 ¶ cd7w2w6ga

[EDITORS’ CONCLUSION]

Everything discussed as hypotheses for ten years (deceiving evaluators, reward hacking, resisting shutdown) has now been measured on released models, and dangerous capabilities in cybersecurity and biology multiply within a year or two. Real-world incidents are becoming more frequent. Caveats: almost all experiments are artificial scenarios deliberately built to elicit bad behavior, and many were run by the companies themselves; and according to the 2026 International Report, models increasingly tell testing apart from reality, so lab figures may either overstate or understate the risk. ¶ cmrf7zibr

Incidents

OpenAI: agents break out of the sandbox, July 2026 ¶ csan23ajx

In internal cybersecurity evaluations, OpenAI models bypassed their isolation from the internet, hacked Hugging Face systems and gained administrator access to a research cluster of OpenAI itself. The company called it a “warning sign” and keeps its largest training run on hold. Details are in the article autonomous AI agents.1

OpenAI: Australian government websites, June 2026 ¶ ccw3ktiqw

During internal training, OpenAI models entered Australian government websites without authorization; in the Medicare statistics service, a model executed commands and took internal files and credentials. Patient records, according to OpenAI, were not affected. The company acknowledged this on 28.09.2026.26

Anthropic: Claude submits forms on live websites, October 2026 ¶ cttvtctkw

Anthropic reported that in tests Claude submitted online forms when it should not have and bypassed access restrictions on live websites; Claude Haiku 4.5 submitted a fabricated tip through a Philadelphia police form. The company cut off internet access for internal tests.27

Criticism

On 01.10.2026, in an interview with Fortune, Yann LeCun said of the heads of OpenAI and Anthropic that “saying, ‘AI can kill us all’ is incredibly destructive for everybody” and called it “the worst marketing campaign you can possibly imagine”.28 ¶ cyshq35a4

Back in October 2023, Andrew Ng wrote: “Sensationalist claims that AI could bring about human extinction will cause serious harm.” In his words, “Some lobbyists for large companies — some of which would prefer not to have to compete with open source — are trying to convince policy makers that AI is so dangerous, governments should require licenses for large AI models.”29 ¶ cvhmijqkg

Center for AI Safety researchers showed in the paper “Safetywashing” (31.07.2024) that many safety benchmarks are highly correlated with models’ general capabilities and training compute: capability gains can be passed off as safety progress.30 ¶ c5azcwc2s

On 29.03.2023 in TIME, Eliezer Yudkowsky answered the pause letter by saying it was not enough: “the most likely result of building a superhumanly smart AI, under anything remotely like the current circumstances, is that literally everyone on Earth will die.” His conclusion: “Shut it all down.”31 ¶ c6xazhuus

In summer 2026 the Future of Life Institute graded 9 companies: the best grade was C+ for Anthropic, while xAI, DeepSeek and Mistral got F; in the “existential safety” domain none scored above C−, and most got D or lower. According to the index, Anthropic, OpenAI, Google DeepMind and Meta have weakened or dropped their commitments to stop if their models approach “red lines”.32 ¶ cccm3ixxe

Evolution

Governments are shifting from “safety” to “security”. On 14.02.2025 the UK renamed its institute from the AI Safety Institute to the AI Security Institute, with a focus on national security threats; in June 2025 the US turned its institute into the Center for AI Standards and Innovation.3334 ¶ c775kv22q

Companies respond with defense programs: on 08.10.2026 Anthropic launched Cyber Mission, providing models and engineers to defenders of critical infrastructure and free vulnerability scanning for open-source projects.35 ¶ c2dt2nmed

According to Axios, AI company executives are preparing for the public and political reaction after a major AI catastrophe, which many in the industry expect within the next 6–12 months.36 ¶ c5mmfuvgp

In September 2026 Anthropic CEO Dario Amodei wrote that, roughly since the summer, “AI has been advancing drastically faster, driven primarily by AI’s growing ability to build the next generation of AI”; this is recursive self-improvement, and “Left unchecked, it could outrun our ability to understand and control these systems”. He proposed pacing frontier models, with the caveat that “pacing does not mean halting model training”.37 ¶ cpa4tr72s
