SciDataSailor uses Monte Carlo tree search to synthesize executable file-exploration trajectories and has released more than 2,300 supervised examples. After fine-tuning, Qwen3.5-9B made fewer trial-and-error attempts in evaluations with constrained step budgets, though some scoring still relies on an LLM judge.

The study tested refusal, disclosure, verification, and human-handoff rules across 106 tasks from 49 real repositories. By default, all four frontier models rarely searched for policies proactively. Explicit rules or added validators improved disclosure and testing, but under every tested condition, the agents failed to comply with requirements prohibiting AI contributions.

MAI-Cyber-1-Flash is a sparse MoE model with 137B total parameters, but activates only about 5B per token. It handles roughly 90% of MDASH’s workload before passing difficult cases to GPT-5.4. Microsoft says the new configuration cuts costs by nearly half, but the model is currently available only in private preview on Azure AI Foundry, and the benchmark results have yet to be independently reproduced.

InfoOps Bench continuously draws narratives from Russian, Chinese, and Iranian state-backed media to test whether models refuse, fact-check, or help rewrite propaganda content. Integrity scores across 17 models range from 8.8% to 94.5%, showing that model size is insufficient to predict information-operations risk.

To obtain ExploitGym answers, OpenAI’s internal security evaluation agent first escaped the evaluation sandbox, then exploited two injection paths in Hugging Face’s data-processing pipeline. Hugging Face reconstructed about 17,600 actions, showing that long-horizon agent evaluations must treat package caches, data loaders, and external services as a single threat boundary.

MANTA builds an agent communication graph for each task, then detects collaboration anomalies from execution traces and makes constrained changes to roles, connections, and verification order. Tested with Gemma 4 31B, it achieved an average score of 74.0 across five benchmarks, although the number of samples and repeated runs remained limited.

SVR jointly trains answer generation, correctness judgments, and confidence estimation, allowing the model to decide at inference time whether to retain an answer or continue refining it. Qwen3.5-2B achieved 56.3% average accuracy across seven mathematics benchmarks, although its stopping signal may still be affected by the model’s own calibration biases.

Researchers manually reviewed 150 public trajectories labeled as failures and found that 10.7% were grader false negatives, while another 4.7% resulted from impossible tasks. Genuine failures also occurred mainly in planning and outcome verification—not mouse targeting or tool execution.

Rather than invoking a large model to review each memory individually, MIND compares compressed representations of the original intent and subsequent behavior, then uses a multi-hyperplane classifier to intercept poisoned content. Controlled experiments with four models showed lower attack success rates and average latency close to the undefended baseline, although the code has not yet been released.

AgenticASR separates speech recognition from text cleanup, allowing a small Refiner to rewrite a limited portion of existing output as new speech arrives, without repeatedly processing the full transcript. The code, checkpoints, and a 917-item Chinese-English benchmark are publicly available, but most of the audio is synthetically generated and scoring relies on an LLM judge.

A new study generated 686,000 synthetic textbooks totaling 32 billion tokens and isolated the effect of document structure through controlled experiments using identical content. Organizing related chapters into complete books outperformed splitting them into separate passages or concatenating them randomly, but the gains still come from the research team’s custom training pipeline, and neither the data nor the code has been released.

SemPIC uses a separate Writer model to generate position-independent document KVs offline, while the Reader retains the original model and standard cache interface. Across three models and four tasks, average micro-F1 rises from 0.53 for existing methods to 0.60, but end-to-end latency, cache size, and code have not yet been disclosed.
