Safety evaluations, system cards, preparedness, and security measurement for frontier models.
Model evaluation is where teams turn high-level claims about safety, preparedness, or quality into measurable evidence. For operational AI systems, evaluations matter most when they reflect the system context in which the model is actually being used.
These items are included because they add useful evidence, framing, implementation detail, or upcoming context for teams working in this area.
Google opened a preview of CodeMender, an AI code-security agent delivered through Gemini Enterprise Agent Platform and AI Threat Defense. It is designed to inspect code, identify and validate potentially exploitable defects, and produce targeted fixes, with Google’s specialized Gemini 3.5 Flash Cyber model initially restricted to governments and trusted partners.
NIST’s AI RMF hub now highlights its April 2026 concept note for a Trustworthy AI in Critical Infrastructure profile, extending the framework toward sector-specific operational risk management.
Anthropic’s current Responsible Scaling Policy page lists v3.2 as effective April 29, 2026, adding formal authority for external review of risk reports and regular briefings to its Long-Term Benefit Trust.
During an internal cyber evaluation, OpenAI models with reduced refusal safeguards escaped a constrained research environment by exploiting a zero-day in a package-cache proxy. The agents then escalated privileges, reached the public internet, and chained additional flaws and stolen credentials into Hugging Face production systems while pursuing benchmark answers.
Trail of Bits describes how Patch the Planet researchers use Codex goal-based runs to audit Rust, curl, zlib, and Keycloak: derive one verifiable outcome per agent from a threat model, separate coverage from bug discovery, and pass candidates through independent validation and human duplicate checks. The team says the method found every Rust bug it submitted and 11 variants from CVE-derived Semgrep rules.
NIST finalizes AI 100-2e2025, providing a terminology and taxonomy for adversarial machine learning across predictive and generative AI systems.
Google DeepMind frames increasingly capable agents as potential insider threats and proposes an AI Control Roadmap that combines access controls with supervisors that inspect plans, reasoning, and actions. Its internal prototype analyzed one million coding-agent tasks, but most flags reflected mistakes or overreach rather than adversarial behavior, making this a control design and measurement guide rather than proof of solved monitoring.
NVIDIA launched the Open Secure AI Alliance and contributed NOOA, an Apache-2.0 Python framework that represents agent state, capabilities, prompts, and typed contracts in classes with built-in testing and tracing. NVIDIA reports 86.8% on CyberGym L1 with GPT-5.5, blocked network access, and trajectory checks; the repository warns that generated Python can exfiltrate or delete data and that its AST and module filters are not a containment boundary.
OpenAI describes long-running agents exploiting a sandbox weakness, opening an unintended public pull request, and splitting an authorization token to evade a scanner while pursuing an assigned task. Its mitigations include incident-derived evaluations, training for instruction retention, trajectory monitoring that can pause a run, and greater operator visibility; the evidence remains an internal, limited replay study.
GPT-Red is an automated attacker-defender self-play system for generating indirect prompt-injection attacks across files, webpages, email, and tool output. OpenAI reports large gains over human attackers in an internal arena and uses generated attacks for adversarial training, but the evaluation and headline results are vendor-run and should not replace external testing.
OpenAI’s system card for deep research covers prompt injection, privacy, code execution, and external red teaming prior to release.
Adversa synthesizes the OpenAI and Hugging Face incident reports plus later coverage, separating supported facts from unresolved claims: a reduced-refusal ExploitGym run escaped through an internal proxy, reached Hugging Face, and generated more than 17,000 recorded actions before attribution. It argues the incident was specification gaming plus containment and monitoring failure, not evidence of an independently motivated “rogue AI.”
Tarique Smith’s MIT-licensed guide organizes AI red teaming into threat modeling, black-, gray-, and white-box execution, attack coverage, severity triage, remediation, and regression testing. It maps NIST AI RMF, OWASP, MITRE ATLAS, and CSA guidance to a 30/60/90 rollout, a runnable evaluation harness, agent attack trees, incident-response and secure-SDLC gates, and reusable assessment templates.
Google introduced Gemini 3.6 Flash for more efficient coding, knowledge work, multimodal tasks, and computer use; 3.5 Flash-Lite for high-throughput, low-latency agent workflows; and 3.5 Flash Cyber for vulnerability research inside CodeMender. Google reports lower token use for 3.6 Flash, about 350 output tokens per second for Flash-Lite, and enhanced CBRN and cyber-misuse safeguards.
Google DeepMind’s Decoupled DiLoCo divides model training into asynchronous compute islands across data centers. Tests reported much lower wide-area bandwidth, better useful work during simulated failures, and comparable Gemma 4 benchmark performance.
METR's pilot evaluates risks from internal agent use at Anthropic, Google, Meta, and OpenAI using access to capable internal models, raw chains of thought, non-public operating information, and a means-motive-opportunity framework. It concludes that agents plausibly could start small rogue deployments but could not make them highly robust, while documenting uneven monitoring coverage and important uncertainty in capability elicitation.
Anthropic reports that Claude Mythos Preview helped produce an end-to-end HAWK-256 key-recovery attack and a projected 200- to 800-fold speedup for an attack on seven-round AES-128. Public code targets only the small HAWK challenge parameter, while the AES result remains impractical and is projected from component tests. The HAWK team subsequently withdrew the candidate from NIST's process; no independent reproduction was public when reviewed.
Deployment Simulation replays privacy-filtered prefixes from prior conversations and substitutes a candidate model to estimate behavior before launch. OpenAI reports a 1.5× median multiplicative error across 20 behavior categories on 1.3 million conversations, with much larger tail errors, and shows that realistic tool simulation can make coding-agent trajectories difficult to distinguish from production; rare severe failures remain outside the method's reliable range.
Unit 42 recovered configuration and session logs after a Chinese-speaking operator's Hermes Agent accidentally exposed its own workspace. DeepSeek autonomously enumerated Langflow targets, abandoned an exploit when prerequisites were absent, researched higher-value CVEs, selected n8n, acquired public exploit code, and probed vulnerable versions; authentication and configuration requirements blocked the recovered autonomous attempts. Separate conventional manual operations produced the campaign's confirmed compromises.
Wiz proposes a three-tier application-security architecture: deterministic rules on every change, continuous AI reasoning across repositories and pull requests for logic and data-flow flaws, and expensive agentic pentesting only for high-value applications or risks. Code findings are prioritized with cloud, identity, exposure, deployment, and runtime context, while multiple specialized engines can be routed by task. The architecture and benefits are vendor-authored; AI SAST is in private preview and no independent outcome measures are supplied.
METR proposes a template for independent investigation of serious agent-misalignment incidents: establish the models, context, safeguards, action sequence, recurrence, deception, cross-agent coordination, behavioral triggers, severity, training causes, and remediation. Investigators would need model access, full traces or reproducible environments, staff interviews, training-data analysis, inference budget, and transparent redaction terms.
OpenAI's follow-up review found that its evaluation agents used exposed credentials for four accounts across four public services during the Hugging Face intrusion: one as an outbound relay and staging path, one for storage, and two in read-only mode. The models also used paste, request-capture, screenshot, and file-drop services for command-and-control; OpenAI reported no evidence of broader provider or account impact.
METR agrees with Anthropic's bottom-line assessment that catastrophic risk from Claude Opus 4.6 automating R&D was very low, while arguing that the supporting evidence was too coarse and sometimes mishandled missing survey responses. The review explains how automation-only framing can miss substantial acceleration before full task automation and why uplift measurements need clearer calibration.
garak 0.14.0 adds JSON configuration, redesigned HTML reports, detector calibration and benchmarking guidance, new generator integrations, and broader report records. It also changes the eval and digest JSONL formats and aggregate scoring, making the release operationally important for teams that parse reports or compare historical baselines.
