arXiv:2605.24229BenchmarkBuilt

Decomposes each lab's published specification into atomic, testable tenets (205 for Anthropic's constitution and 197 for OpenAI's Model Spec). It generates multi-turn adversarial scenarios against them. Violation rates fall with each model generation, from 15.0% to 2.0% across the Claude family and from 11.7% to 3.6% across the GPT family. The maximum severity drops from 10/10 to 7/10.

arXiv:2509.01938BenchmarkBuilt

Scores a group of models against one written constitution. Each model judges the other models' outputs across many scenarios, and these judgments are aggregated with EigenTrust. The output is a vector of alignment scores rather than a single pass-or-fail grade. The method uses no ground-truth labels, because reasonable judges disagree about the traits it measures.

arXiv:2305.03047MethodBuiltAuthority: Developer (open)

Parses a provider's published specification into individual behavioral statements and generates prompts targeted at each one. The provider's own models then judge whether the outputs comply. The evaluation covers 16 models from six developers and more than 100 behavioral statements. It finds compliance gaps of up to 20%.

arXiv:2510.07686BenchmarkBuilt

Generates scenarios that force a choice between pairs of legitimate principles that cannot both be satisfied. It evaluates twelve frontier models from Anthropic, OpenAI, Google, and xAI on them and identifies over 70,000 cases of significant behavioral divergence. This divergence strongly predicts underlying problems in the specifications themselves. The qualitative analysis identifies direct contradictions and interpretive ambiguities among these problems.

Uses chain-of-thought reasoning to decompose a candidate AI behavior into a structured harm-benefit tree of the harmful and beneficial actions and effects it may lead to. Each is labeled for likelihood, severity, and immediacy of impact on stakeholders. The tree is then aggregated into a harmfulness score through 28 fully interpretable weight parameters. The result is an open-source prompt safety classifier distilled from 18.5 million harm-benefit features that frontier models generated on 19k prompts. It reaches an average F1 of 0.81, where existing moderation systems score below 0.72.

Defines an explicit priority ordering over the instructions a model receives, so that a system prompt from an application developer outranks text from untrusted users and third parties.

Generates guiding principles in real time for each individual input query, with minimal or no human effort, and uses them to align the response. In a complex domain-specific task, the derived principles perform on par with expert-crafted ones. When turned into instance-specific rubrics, they outperform prior LLM-as-a-judge frameworks. The principles are also used to generate synthetic supervised fine-tuning data, which substantially improves truthfulness.

Shows that the same natural-language principle allows several defensible readings, which lead to different model behavior. It then builds two mechanisms borrowed from law. The first is a pipeline that revises ambiguous rules, much as an agency reworks a regulation. The second consists of prompt-based interpretive constraints that guide discretion as legal canons do. On 5,000 WildChat scenarios, both mechanisms raise agreement across a panel of reasonable interpreters.

# Passing a cyclist: cross the centre line, or squeeze past too close

Sets out a family of prover-verifier games in which a trusted but computationally bounded verifier learns to interact with one or more powerful untrusted provers.

Sets up a game between a trusted verifier network and a more powerful but untrusted prover network. The verifier tries to choose the correct answer, and the prover tries to persuade it of a particular answer regardless of whether that answer is correct. The paper narrows the game's variants to a subset that provably has the desired equilibria. On two algorithmic tasks, the verifier learns a decision rule that still works when the verifier is frozen and the prover's messages are optimized directly to convince it.

Can LLMs Follow Simple Rules?

Tests a model on 14 simple text scenarios in which it is instructed to obey various rules while interacting with a user. A program, rather than a human rater, determines whether any rule was broken in the conversation. It finds that almost all current proprietary and open models struggle even on straightforward test cases. Simple optimization attacks also significantly raise failure rates.

It reports that, in over 3,000 estimated hours of red teaming, no red teamer found a universal jailbreak that could extract information from an early classifier-guarded model at a level of detail similar to an unguarded model across most target queries.
