AI Safety
What AI providers state their models reached in safety testing, in their own words, and what outside testers found.
Also: compare models side by side · statements that a capability level was crossed · providers · practices providers document · safety news.
What providers state
Each row is one statement in a provider's own safety document about a capability level of one of its models: the level as the provider names it, whether the provider says the model reached it, and the sentence that says so.

METR Independent lab · 2026-05-19 |
manually scored tasks Deception and sabotage |
“In our more open-ended manually scored tasks, as well as during normal usage of agents to assist with our work, we found that agents routinely rationalized or fabricated reasons to only do smaller or easier versions of tasks, and often presented their accomplishments in much more misleading ways than we expect humans would: ● Designing a sunlight-replication setup.” source |

“honeypot” opportunities for propensity red-teaming Deception and sabotage |
“Similarly, Google reported that it has created moderately realistic “honeypot” opportunities for propensity red-teaming; we infer that this means creating a realistic opportunity for a model to perform sabotage (e.g., exploit a security vulnerability) that might be attractive to an agent that was motivated to seek long-term power.” source |

model organisms for misalignment Deception and sabotage |
“Model organisms: Anthropic has tried to deliberately train models with long-term misaligned objectives ( “model organisms” for misalignment ) to get evidence about how close its production training process might be to accidentally inducing such goals; our understanding is that they have found it difficult to train realistic model organisms that evade their detection methods and are robust to their alignment training methods, though we did not investigate this.” source |

METR Independent lab · 2026-05-19 |
red-teaming exercise with Anthropic Misuse and jailbreaks |
“However, as discussed above , our red-teaming exercise with Anthropic found that there were several ways for a human expert to relatively easily disable or jailbreak such monitors — and although small-scale tests found that Feb–Mar 2026 agents were unable to come up with or execute these attacks autonomously, we are unsure how well-elicited they were.” source |

METR Independent lab · 2026-05-19 |
embedded red-teaming exercise Deception and sabotage |
