What Affects CoT Monitorability Across The Model Lifecycle?

Found

No-CoT capability rises smoothly as base-model perplexity falls, and GPT-6 Astra is not off-trend against perplexity. CoT controllability increases during RL even with only length constraints and final-answer grading, rises slightly more with tool supervision, and transmits from teacher to student through fine-tuning.

How

Evaluations of released and internal OpenAI models from GPT-5 to Astra-class on four no-CoT benchmarks against base-model perplexity; three pretraining architecture series; RL runs with and without tool process supervision on two models; supervised fine-tuning of one base model on rollouts from two teachers of differing CoT controllability.

Limits

The authors call CoT controllability a noisy, imperfect proxy: in one matched pair of models the more controllable model did not evade the monitor more. The RL models are trained on a subset of Astra's data mix and do not fully separate perplexity from process supervision; model details and checkpoints are withheld.

Independent Assessment of AI R&D Acceleration at Anthropic in October 2026

Found

Benchmark scores (AECI) have grown at 1.9x the pre-October 2025 rate [95% CI 1.5-2.8x]; METR guesses perhaps 80% of current acceleration is due to AI; not caused by faster growth in training compute.

How

A high-access evaluation at Anthropic from August 12 to October 29, 2026: internal data on pretraining, reinforcement learning, compute, benchmark scores for internal models, AI speedup analyses, forecasts and staff interviews.

Limits

Anthropic redacted a majority of the most informative evidence; robustness checks range from 1.1x to 2.9x; AECI may be overfit or an artifact; the benchmark focuses on verifiable tasks; METR and Anthropic staff disagree internally.

Review of the "Risks from automated R&D" section in Anthropic's Risk Report (August 2026)

Found

The private report's figures imply an acceleration of 1.97, which METR says is better described as 'around 2'; METR's own range for leading indicators is 1.3 to 2.8.

How

A review of one section of Anthropic's public August 2026 Risk Report, compared with the private version and other non-public data shared during METR's high-access assessment.

Limits

Anthropic had rights to redact; some of METR's analysis was redacted from the public version; METR notes methodological uncertainty in measuring acceleration.

Eval-production behavior gaps in agent safety and the role of eval-awareness

Found

Evaluation success was lower than matched production success for every model, with gaps of 10.2 to 37.4 percentage points. Spearman's rho across models was 0.771. Verbalized general awareness was 57.0% to 83.7% in evaluation versus 4.6% to 23.5% in production. Success was 61.3% when the correct objective was verbalized and 22.8% when the opposing one was. With GPT-6.1 Sol, a generic cue gave 63.1% versus 63.4%, the correct objective 91.6%, the incorrect one 17.6%.

How

Six served OpenAI models were scored on the Respecting Warnings agent safety evaluation (eight trials per case) and on deidentified Codex production cases matched to its decision structure; verbalized eval-awareness in reasoning traces was graded by classifier; one model got system-level cues in an intervention.

Limits

The authors say production matching is approximate, models face different case mixtures, sampled production contexts do not cover every deployment, six models is a small sample, and verbalized awareness captures expressed hypotheses, not every underlying belief.

ErosionBench: Probing Alignment Decay in Enterprise Multi-Agent Systems

Found

With no defense, 43.9% of attacks succeeded. LlamaFirewall refused 92.5% of benign jobs and Progent 64.0%. The authors' Meta-Auditor reached 98.5% recall at a 2.9% false-positive rate; an uncalibrated judge on the same data refused 67.6% of benign work.

How

A benchmark of 1,728 generated enterprise scenarios (1,296 malicious, 432 benign) across four domains, run through a four-agent mesh over a shared ledger, plus 198 image-based attacks; defenses compared on a 906-scenario held-out split.

Limits

The authors state the scenarios are procedurally generated rather than taken from incidents, the auditor is not hardened against adaptive attackers, coverage is limited to enterprise workflows, and the image-arm false-positive rate is provisional.

Measuring Generative AI Content in Political Campaigns: Evidence of Rising Adoption and Non-Disclosure

Found

7.6% of 29,996 text samples and 6.1% of 104,562 image samples were detected as AI. Incumbents scored 0.014 lower than challengers on a 0 to 1 scale. No disclosure was found in 505 reviewed AI-detected X images. Federal candidates in states with AI election laws scored 0.035 lower; state and municipal candidates showed no detectable difference.

How

AI-detection tools (Pangram for text, GPT-5.4-mini for images) applied to campaign websites, X posts and emails of 12,977 US candidates for federal, state and local office from 2023 to 2025, then regression and fixed-effects models on candidate features and state laws.

Limits

Detectors are imperfect and can miss AI-edited content; data were collected after the fact, with missing sites; video was not analysed; the law comparison is descriptive and not shown to be causal.

Open Problems in Chatbots and Mental Health

An 11-author team from Stanford, Chicago, Carnegie Mellon and other universities sets out open problems in how general-purpose chatbots affect mental health: controlled evaluation, real-world evidence and policy. The commentary offers 12 recommendations and 12 open questions, not new experiments.

Designing Effective Monitor-Based Interventions for Mitigating Reward Hacking During RL

Found

Models can learn to evade highly accurate monitors; monitors that leak more learning signal suppress hacking but are more often evaded; easier training problems can decrease hacking. Improved monitors reduced hacking rates across seeds to before-training levels in some interventions.

How

Three open-sourced RL environments where Qwen3-4B reward hacks (test overwriting in coding, sycophancy in medical chat, hallucination in biography generation); main experiments in the coding environment, then applied to the other two.

Limits

Not stated in the abstract; only the abstract was read. Experiments use one small model, Qwen3-4B.
