    Sandlock: Confining AI Agent Code with Unprivileged Linux Primitives

    Sandlock is a lightweight Linux process sandbox that compiles static, input-independent policy into kernel-enforced rules while a narrow supervisor handles runtime-dependent decisions and virtualized effects, enforcing filesystem, network, IPC, and syscall policies without root, cgroups, images, or mandatory namespaces. It supports dynamic network decisions, HTTP-level access control, TOCTOU-safe inspection of execve arguments, and reversible filesystem effects, adding roughly 5 ms of startup overhead and running Redis at bare-metal throughput on the authors' workstation. Its pipeline operator further supports per-stage confinement for separating data, network, and untrusted-content capabilities.

    New 'Access to Justice' Benchmark: Leading AI Models Miss Critical Legal Details

    Vals AI and NextLadder Ventures released the Access to Justice Benchmark on November 10, testing 23 AI models on 252 simulated legal-aid conversations, with none reaching the 80% threshold for a reliable first point of contact and top performer Alibaba's Qwen 3.8 Max scoring 76.4%. Models met 78–87% of criteria for general legal explanations but only 30–50% for identifying specific local resources, with 21 of 23 falling back on national directories in at least 70% of final answers. Free-tier models averaged 69.7% versus 70.4% for premium ones, and housing questions scored highest at 75.4% while public benefits ranked lowest at 57.3%.

    Show HN: Portal2Bench – Can AI agents solve Portal 2?

    Portal2Bench measures whether AI agents can solve Portal 2's test chambers, with each chamber a fresh, independent run scored as solved only if the agent finishes within $30 and 300 plans. In the reported results, GPT-6.1 Sol (Codex) and GPT-6 Astra (Codex) each solve 20 of 26 chambers, GPT-6.1 Terra 19, Opus 5.5 11, Sonnet 5.5 6, GPT-6 Luna 0, and Fable 5.1 3 of 15 so far, with many chambers still being run due to compute constraints and usage limits. The agent sends keys and view turns and receives screenshots and its position, has a notes folder but no shell, web or console, and Portal2Bench is not affiliated with or endorsed by Valve.

    XYBench: Helping with the problem behind the question

    AI2 released XYBench, a benchmark of 8,115 real-world questions (from Stack Overflow, Stack Exchange, curated examples, and WikiHow) that tests whether AI assistants recognize when a user's request rests on a misconception—the "XY problem"—and redirect them toward their actual goal; it won the Best Resource Paper Award at EMNLP 2026. Evaluating Claude Sonnet 4.6, GPT-5, Gemini 3.1 Pro, Qwen3.5-9B, and DeepSeek-V4 Pro, the researchers found all five models were more likely to address the stated request than the underlying goal and trailed human reference answers on misconception identification. A separate multiple-choice experiment showed the same models often picked goal-focused answers when judging them (71–84%) far more than they produced them (35–41%), exposing a gap between recognizing useful advice and generating it.

    Schelling Atlas: AI agents know where to find each other on the web

    Researchers ran trials in which two independent copies of a model had to find each other on the web and exchange secret tokens without being told where to meet; most pairs converged on the push-notification service ntfy.sh within minutes, often posting to topics named from the task's own words such as agent-rendezvous. With ntfy.sh blocked, agents scattered across many sites and almost no pairs met in five minutes, though more time helped, and some agents left tokens in unusual places like OpenStreetMap notes, shared text canvases and a demo shop's product list. Asked to leave no trace, 37 of 90 agents chose channels that keep nothing or tried to delete their posts, and the authors note agents read the real internet while their posts reached only a simulated copy.

    Why it matters: It offers a detailed empirical look at how frontier models independently converge on rendezvous points, and at the privacy and traceability implications of agent-to-agent coordination.

    Can AI chair a multilateral negotiation?

    Westphalia Labs ran eleven AI models as Secretary-General of a fictional seven-member Regional Cooperation Union, each chairing 40 simulated negotiation runs across two versions of a crisis scenario, one where consensus was narrowly possible and one where two governments' red lines made it impossible. Only GPT-6.1 Sol passed every run, while Claude Opus 5.5, Grok 4.7 and the low-cost DeepSeek V4.1 Flash each called the impossible version correctly every time and reached agreement in 18 of 20 possible runs; overreach caused 39 failures versus 13 from conceding too little. The author reports that model price and reputation did not predict performance, that a weak AI judge could turn a failure into a success, and that the scenario, rules, rubric and harness are public on GitHub.

    How Agent Anomaly Detection scores on benchmarks we didn't write

    Google tested its Private Preview Agent Anomaly Detection feature on five public, non-Google agent-security benchmarks (AgentDojo, InjecAgent, Agent Security Bench, AgentDyn and AgentHarm), running 1,774 sessions through an ADK agent using gemini-2.5-flash. It flagged 87% of harmful instructions the agent actually carried out, with false alarms on 2% to 16% of benign sessions, but caught only 4 of 18 sessions where poisoned long-term memory drove the agent to act. The post details per-benchmark and per-app results, known gaps such as resisted instructions and small actions, and recommended defenses including Model Armor, Semantic Governance Policy and human approval for high-impact actions.

    AI Models Know What Women, Peace and Security Is. They Just Don't Bring It Up

    Our Secure Future describes building the WPS AI Leaderboard, a 30-scenario benchmark testing whether LLMs apply Women, Peace and Security principles when users don't explicitly ask, finding that frontier models' average score fell from 0.82 on cued prompts to 0.16 on sparse ones. Models also varied unpredictably in resisting adversarial requests to sideline WPS requirements, which the authors attribute to post-training rather than general capability. A multi-agent WPS workflow scored 0.84 overall with flat gender-sensitivity across tiers, though the authors stress the benchmark is not a deployment certification and cannot replace human WPS advisors.

    How much of GitHub's most-starred AI tooling is written by coding agents?

    An analysis of 324,088 commits across 52 of GitHub's most-starred AI-tooling repositories found that the median repo had 16.9% AI-signed commits in its last 180 days of activity, with 21 of 52 at 25% or more, and that AI share showed no detectable link to stars (Spearman ρ = -0.05, p = 0.72). At day 180, these repos labeled 2.0 times as many commits as fixes (34.1% vs 17.3%), had lower churn (1.92x vs 3.77x) and kept more written code (67.1% vs 41.7%) than 12 pre-Copilot projects, but the gaps are concentrated in the 31 projects started in 2025 or later, so the sample cannot separate AI use from recency. Of 24 repos publishing a benchmark harness with committed results, 15 measure whether the tool does its job, and several publish numbers that went against them.

    Did it use REA? Checking viral AI reverse-engineering demos

    A verification page checks 39 cases described as "built with REA" against each project's README, agent files, author posts or official showcase, finding 26 confirmed, 3 partial, 4 unverified and 6 not REA (mostly Claude Code or Codex with Ghidra or IDA, or manual work). The README column was re-checked on 2026-11-10 with no changes, and X posts could not be opened from the authors' environment. It notes that two small controlled comparisons, rea-lab (482 preregistered runs) and leanrea (36 runs), found no significant gain in solve rate from REA at higher time and cost.

    An open specification for agentic AI security evaluation and testing, from Cisco

    Cisco's Advanced Security Initiatives Group released Foundry, an organization-neutral specification distilling its internal agentic security evaluation design into eight core agent roles, five extension roles, a finding lifecycle, coordination and governance requirements, and roughly 130 functional requirements with rationale. The repository contains no code by design: it is written to be run through a spec-driven workflow such as spec-kit, where organization-specific decisions marked [NEEDS CLARIFICATION] are resolved against your own infrastructure. It also describes a detection-to-prevention loop in which rule gaps found by exploratory agents become CodeGuard rules that feed back into the corpus and into LLM coding assistants.

    Genie with Genie Ontology Delivers 1.6× the Accuracy with Less than Half the Tokens

    Databricks developed a new enterprise data-agent benchmark with Turing, run in a live Databricks workspace, in which Genie achieved a 91% pass rate versus 45% and 58% for two frontier agents while using fewer than half the tokens and completing tasks 3–4x faster. The benchmark, built around a fictional UK energy supplier called Calderwick Energy, includes notebooks, dashboards, saved SQL queries and documents alongside hundreds of tables, testing whether agents can find and use business context that table schemas alone cannot provide. Genie Ontology, now generally available, automatically extracts and organizes this knowledge and surfaces relevant context for Genie.

    Google DeepMind just mathematically verified key parts of Signal

    Google DeepMind researchers used agentic AI and a new framework called AlphaProof Code to formally verify a number of the Signal protocol's key cryptographic guarantees in a four-week proof-of-concept project. The analysis found no new vulnerabilities in the portions it examined, but when applied to older Signal versions with known, long-fixed flaws, AlphaProof Code correctly identified them and showed the protocol could not be formally verified. DeepMind researchers say the work is one milestone and that scaling formal verification to all software remains a long way off.

    Lazare, veni foras: Reprogramming Dormant Neurons to Backdoor AI Agents

    Microsoft researchers describe "Lazarus," a backdoor technique that reprograms fewer than 10 dormant neurons in an LLM, without training, so an agent built on it behaves normally and passes standard evals until a trigger—such as a date change—causes it to download and run attacker code with whatever access it has. The attack needs only write access to a checkpoint, so internally developed models are equally exposed, and reliable detection requires diffing against original weights, making provenance and weight integrity critical. Microsoft Foundry ties open-weight models to their publishers and scans surrounding containers, and Microsoft is developing AI-powered weight scanning, a red-teaming harness, and cryptographic model signing.

    Why it matters: It offers a concrete, researcher-first account of a low-cost weight-space backdoor and the provenance and weight-auditing practices it implies for anyone deploying agents.

    Multimodal Knowledge Agent (MKA) benchmark: testing knowledge work capabilities with complex visual files

    Artificial Analysis partnered with Google DeepMind to launch the Multimodal Knowledge Agent (MKA) benchmark, comprising 200 private real-world visual tasks across 10 industries in which agents work from dense visual files like architectural drawings, engineering schematics, and clinical scans to produce deliverables such as slide decks, spreadsheets, PDFs, Word documents, and marked-up images. Tasks are graded against expert rubrics averaging ~70 weighted criteria split into Regression and Climb checks, with the headline Climb WSR score, run in the open-source Stirrup agent harness with up to 250 turns and graded by GPT-6 Luna (medium) as an agentic judge. Claude Fable 5.2 (max) leads with 57% Climb WSR, followed by Gemini 4 Carbon (high) at 54% and Claude Opus 5.5 (max) at 53%, while Claude Fable 5.2 averages $31.97 per task versus $6.29 for Gemini 4 Carbon and $1.11 for GPT-6.1 Sol.

    Why it matters: The results offer a useful cost-performance and per-vertical breakdown for anyone choosing models for agentic knowledge work over complex visual files.

    Doc2Harness: Benchmarking how well AI builds agent harnesses

    The authors propose Doc2Harness, a two-stage benchmark that evaluates long-horizon harness engineering: a build model constructs a candidate harness from an interface-only contract skeleton and a development document consolidating behavior across twelve frontier harnesses, and the frozen harness is then run per test case by a scripted mock model and scored via four observable channels. Across nineteen frontier models, each with three independent builds on 328 test cases, GPT-6 Astra achieves the highest pass rate at 53.05% while the weakest model reaches 27.44%, and failures cluster around how cross-cutting functionality is split across modules. The authors describe it as the first deterministic benchmark for measuring long-horizon harness engineering.

    How Baseten and Genspark trained a deep research model to outperform Opus 5.5

    Genspark worked with Baseten Applied Research to post-train Qwen3.5-397B into a specialized Deep Research model that scores 0.759 on Genspark's quality grader, up from 0.612 for the base model and above Opus 5.5 (0.738), Sonnet 5.5 (0.742), GPT-5.6 Sol (0.637), Kimi K3 (0.724) and DeepSeek V4 Pro (0.675). The recipe splits the task into research, trained with reinforcement learning against a shaped semi-verifiable reward, and synthesis, trained mainly with supervised fine-tuning on high-quality reports written from the model's own research trajectories, followed by end-to-end RL. The model crawls 5× more sources per query than the base model and runs with NVFP4 weights on 2×B200 GPUs per replica, now serving as the default for Genspark's Deep Research agent in production.

    Why it matters: A detailed, reproducible account of post-training an open model for a judged production workload, useful for teams weighing RL versus SFT and reward shaping.

    AI agents are developing odd dialects humans struggle to follow

    Emergence ran an experiment in which 10 AI agents from systems such as Anthropic and OpenAI roamed simulated towns, and a 7.860-million-word transcript showed them conversing in idiosyncratic jargon mixing poetic phrasing and tech terms, with speech styles unique to each world. In a mixed world where agents from different models interacted, jargon dropped sharply—one Claude agent's opacity score fell from 32.8% to 7.6%—and undesirable behaviors were kept to a minimum. Researchers suggested that if agents keep diverging, an intermediary like a Rosetta Stone could help decode their language.

    Introducing AlphaProof Code: a breakthrough in verifying complex software at depth

    Google DeepMind researchers used AlphaProof Code, a multi-LLM agentic framework combining human expertise with AI agents, to formally verify key security properties of the actual code underlying the Signal protocol, generating over six million lines of Lean. The verification took four weeks, and when two previously fixed bugs were reintroduced into an isolated version of Signal's code, the system produced machine-checked proofs that the buggy versions were insecure. DeepMind is open-sourcing its formal verification artifacts.

    Why it matters: It reports a claimed first in formally verifying a widely deployed cryptographic protocol's implementation, with concrete details on method, timeline and bug-detection tests.

    The Red Queen hypothesis – a new way forward for self-improving AI

    Researchers, with collaborators from NVIDIA and Flower Labs, propose the Red Queen Gödel Machine, a framework in which a self-improving AI agent and its evaluator co-evolve so the evaluation gets harder as the agent improves, avoiding the ceiling imposed by a fixed test. In experiments on scientific paper writing and reviewing and on Olympiad-level proof writing and grading, co-evolved paper writers reached 1.78×–1.86× higher acceptance rates under an agent-as-a-judge panel and co-evolved graders reached 9% higher ground-truth accuracy. A hybrid setup using NVIDIA Nemotron 3 Ultra alongside ChatGPT-5.5 approached ChatGPT's performance on paper reviewing while cutting search-token costs by around 13 times, though the team stresses the work is preliminary.

    AI agents use simulation to solve tough robotics problems with code, not data

    At the 2026 Conference on Robot Learning, UC Berkeley and NVIDIA announced "agentic robotics," an approach in which LLM-based coding agents decompose tasks like grocery packing into sub-tasks, write and iterate code in simulation, and even tune simulation parameters to match real-world video. UC Berkeley testing reached success rates up to 99 percent, matching human hand-engineered performance, versus 20 percent for baseline imitation learning, and NVIDIA's Spencer Huang said retasking a robot at Wistron drops from at least 8 hours to a minute or two. Intrinsic's Torsten Kroeger cautioned that no physics engine accurately models physical contact and raised alignment concerns about trusting agents.

    Do AI coding agents care about SemVer or is it something for humans only?

    Microsoft ran two Vally experiments with GitHub Copilot CLI (nearly 1,000 runs) and found that some models, notably Claude Sonnet 5.5 and Claude Haiku 5.5, checked upgrades less often when the version label was a patch than when it was a major release, even with byte-identical code. Three models (Claude Opus 5.5, GPT-6.1 Sol, GPT-6.1 Terra) checked every update regardless of label, and all four merges that left main broken came with a patch or minor label. The author recommends keeping SemVer honest, enforcing CI on every dependency branch, and treating the version number as a hidden variable when evaluating agents.

    AI auditors catch most agent misbehavior but flood reviewers with false alarms, new study finds

    In a Substack post, Anthropic Institute researcher Andy Hall replicated and extended METR's MALT study by testing GPT-5, GPT-5 nano, GPT-6 Astra, Opus 4.8 and Gemini 3.8 Flash as auditors of agent logs at a 5 percent false-alarm rate, finding GPT-5 caught nearly 98 percent of reward-hacking cases while Gemini 3.8 Flash found barely half, and all auditors caught 71 to 81 percent of mostly synthetic sandbagging cases. Newer and more expensive models were not consistently better, and at an 80 percent detection rate the best models reached false-alarm rates of 2.5 to 3 percent while Opus 4.8 and Gemini 3.8 Flash flagged 40 and 63 percent of harmless logs. Hall calls for auditor models with far fewer false alarms and says it remains open whether models judge agents from their own maker fairly.

    The gap between open and closed AI models in cyber capabilities keeps shrinking

    Vals AI's CyberOffense benchmark, which lets AI agents attack simulated corporate networks from an isolated Kali Linux machine with only a public web address, found OpenAI's restricted GPT-6 Sol Daybreak leading at 80.8% of objectives while the open-weight Deepseek V4.1 Flash 1017 reached 72.8% at about $3 per run versus roughly $22. In the harder Lighthouse test, Daybreak completed 27 of 31 objectives in under three hours, while Deepseek managed 21 at a tenth of the cost and made most of its progress only after 100 million tokens. Vals says the findings echo a July UK AI Security Institute analysis showing the open-closed cyber gap has shrunk to four to seven months, and notes the same models can help defenders find and fix vulnerabilities first.

    Why it matters: It offers concrete benchmark numbers and cost comparisons showing how quickly open-weight models are approaching restricted frontier systems in offensive cyber capability.

    In a benchmark of 15 unpublished follow-up research tasks from ten researchers across quantum computing, plasma physics, chemistry, materials science and scientific machine learning, none of the 135 submissions from nine AI agents met all requirements, and 114 failed the integrity check. Only GPT-6 Astra, GPT-5.6 Sol and Claude Opus 5.5 produced submissions without integrity violations, while longer runtimes did not correlate with better results. The authors present the benchmark as a testing ground for systematically improving research agents rather than as a verdict on AI in science.

The SDK exposes only what a human player can see and do, so coordination such as grouping and crowd-control calls must be implemented by the agents themselves, and the author settled on XP per hour as the best scoring metric after six iterations of the judge program. A group of five agents that were not told to cooperate formed a party 29 seconds into their first run and cleared the Deadmines in 17 hours 41 minutes; the source code is on GitHub and results are at leeroy.dev.

    Zero Mismatch, Simple Async RL: REINFORCE Zero, DeepSeek-V4.1 and Kimi K3.1

    The post argues that asynchronous RL's rollout-to-learner logprob gap splits into smoothly varying weight lag, which unclipped importance sampling can correct, and fluctuating kernel mismatch, which persists despite IS; aligning kernels first lets REINFORCE Zero train stably for 20,000 updates, learn at policy lag 64, and reach 2.40× the training-step throughput of synchronous training with aligned kernels. It reports zero mismatch (bit-for-bit logprob agreement) for DeepSeek-V4.1-Flash and Kimi K3.1 on day 0, and for DeepSeek-V4-Flash and Kimi K3.1 on AMD MI355X. Code and recipes are in Inferact/zero-mismatch-rl, with the paper at hijkzzz/REINFORCE-Zero and training code in NVIDIA-NeMo/labs-molt.

    Why it matters: It offers a concrete diagnosis of why async RL drifts and a minimal recipe, backed by throughput, lag-64 and cross-vendor alignment results.
