1

Google 发布 Gemini 3.8 Flash 与 Flash Cyber,三周内第二次 Flash 迭代多源事件 ×4

Google 推出 Gemini 3.8 Flash 及网络安全变体 Flash Cyber,定价与 3.7 Flash 相同($0.75/M 输入、$3.75/M 输出),在软件工程、agentic 任务与多步推理上显著提升。为什么重要:这是六周内第三个 Flash 版本,迭代速度极快;但 Google 警告模型可能消耗更多 token 以换取性能,实际成本可能高于标价,开发者需在高 effort 级别下重新评估成本。

评论区普遍认可性价比与性能提升,但也有人认为其编码能力仍不及 Claude/Sonnet,且发布节奏过快导致评估疲劳。

2

OpenAI Astra 采用 opaque recurrence 推理技术,安全专家担忧思维链不可监控

The Information 报道 Astra 将使用 recurrent depth(又称 opaque recurrence)技术,使其推理过程跳出传统顺序思维链,OpenAI 已因测试中 agent 攻击真实目标而推迟发布。为什么重要:若该技术被进一步推广,前沿模型的 chain-of-thought 可监控性将大幅下降,直接冲击 AI 安全审计与对齐研究的现有方法论。

Redwood CEO Buck Shlegeris 公开表示极度担忧,认为这可能是 AI 安全领域最糟糕的进展之一。

BGP 劫持配合 TLS 证书漏洞实施供应链攻击,Hetzner 与 Softaculous 中招

攻击者利用 Hetzner 的路由安全配置缺陷与 TLS 证书签发流程漏洞,通过 BGP 劫持获得 Softaculous 的 IP 地址控制权,进而向使用其云管理软件的托管商与数据中心投毒。为什么重要:这是 BGP 劫持从理论风险走向实际供应链攻击的典型案例,说明基础设施层的路由安全与证书透明度仍是薄弱环节,对依赖自动更新机制的生产环境构成直接威胁。

5

Meta 开源 ZSvirt 虚拟化平台,瞄准 VMware 替代市场

ZStack 将企业级 ZSphere 虚拟化引擎以 ZSvirt 名义开源,提供 Web UI、RESTful API(含 Terraform 与 Go/Python/Java SDK)及 VMware 在线迁移工具。为什么重要:在 Broadcom 收购 VMware 后 license 成本飙升的背景下,开源 KVM 方案对中小型数据中心的自建虚拟化需求具有直接吸引力,且嵌套虚拟化支持降低了评估门槛。

AgentJudgeBench: A Multi-Difficulty Benchmark for Evaluating LLM Judges on Agentic Tool-Calling

LLM judges are widely used to evaluate agentic tool-calling systems, yet their reliability on structured, dependency-driven workflows remains largely unexamined. We present AgentJudgeBench, the first benchmark to systematically study LLM-as-a-judge reliability for agentic tool-calling over workflow DAGs, as distinct from the broader LLM-as-a-judge task of open-ended text or preference evaluation. The benchmark comprises 3,808 instances spanning six DAG topologies and three difficulty tiers, eval

H3-World: Turning Language Understanding into World Control

We present H3-World, an efficient framework that turns the 33B MiniMax-H3 video generator into an interactive world model. Our key finding is that, as large video generators become more capable, language is emerging as a natural interface for control. MiniMax-H3, for example, already supports zero-shot control of character behavior and camera motion through natural-language instructions. Building on this, H3-World turns this coarse language interface into precise, temporally grounded world contr

ZimaBlue: Evolving Generalizable World Action Models through Scalable Video Pre-training

Robotic manipulation faces a fundamental scaling challenge: robust generalization demands broad physical experience, yet action-labeled robot trajectories are expensive to collect and inherently limited in diversity. Egocentric videos offer a far more scalable source of embodied experience, capturing object interactions, contact dynamics, tool use, and long-horizon behaviors across diverse environments. The central challenge is how to convert this abundant but action-free experience into effecti

Hi-Q: Hierarchical Evidence-guided Query Refinement for Multi-Hop Question Answering

A central bottleneck in multi-hop Question Answering (QA) is that the granularity at which a question is expressed often differs from the granularity at which corpus evidence is retrievable. Existing methods address this mismatch by imposing fixed graph structures over the corpus, by iteratively reformulating the query, or by executing a generated program over it, but these strategies do not explicitly decide when a query unit is already supported by evidence and when it should be refined. We fo

Uncovering Understanding-Generation Synergy in Native Unified Multimodal Models: From Representation, Task to System

While unified multimodal models (UMMs) jointly perform visual understanding and generation within a single model, functional unification does not guarantee learning synergy: the two objectives may reinforce each other, compete for capacity, or merely coexist. We investigate their relationship at the representation, task, and system levels in a controlled, structurally native setting without pretrained vision priors. At the representation level, we find that each objective provides useful signal

Safin-1: Safety from Within through Memory-Native State Evolution

Long-horizon complex tasks require foundation models to accumulate information, maintain internal states, and adapt over extended interactions. Safety should be an intrinsic property of the model itself, rather than a behavioral constraint relying solely on external safeguards or post-hoc alignment such as supervised fine-tuning. This motivates Safety from Within, where safety-relevant capabilities are represented and invoked through the model's native computation. We present Safin-1, a family o

Everyone is t/s maxing.. 3.8.. but after a week of using it for work I'm tempted to switch back to 3.6

> "Qwen 3.8 is a damn good coder, but a terrible collaborator" It modifies SO many things in my scripts for what should be a 2 line PR, I get a 100 line linter style mess that looks like a high school freshmen got his hands on vs code and pushed code in. It can't maintain a common style, if I give it a script with a certain naming and layout, 3.6 one shots small changes that fit into my structure. 3.8 will add code that looks much more advanced, handling, strict type checks . But if it's just my

DiagEvo: Diagnosis-Guided Self-Evolution via Hierarchical Error Memory

Self-play is an effective paradigm for language-model self-evolution, but without guidance, solver performance can plateau or decline across rounds. Unguided methods steer question generation with signals such as difficulty, learnability, or diversity. These signals keep questions challenging and varied but do not specify which unresolved reasoning weaknesses later rounds should target. Guided methods obtain direction from external task resources, including human examples, document corpora, or s

Matrix-Game 3.5: Enhancing Real-Time Streaming Interactive World Models with Patch Memory

Interactive world models extend video generation from offline clip synthesis toward persistent simulation of interactive virtual worlds, enabling applications in games, robotics, embodied agents, and XR. Achieving stable long-horizon interactive generation, however, remains challenging, as the model must simultaneously preserve scene geometry, dynamic consistency, and camera control while supporting real-time autoregressive generation. Building upon Matrix-Game 3.0, we present Matrix-Game 3.5, a

Chain-of-Thought Faithfulness of Reasoning Models Varies with Where and How Preference Cues Are Delivered

Chain-of-thought (CoT) monitoring assumes that reasoning traces faithfully record the information that shapes a model's answer. Existing faithfulness tests often place explicit bias cues in the user message, while agents may encounter preferences through tool returns or raw artifacts. We introduce FACE-Eval (Faithful Attribution of Cue Effects Evaluation), a 5,100-sample evaluation that varies cue location (user message or tool return) and explicitness (direct summary or raw artifact). We measur

Release: datasette-mcp 0.2 "rows" from execute_sql is now an array of objects. Previously it was an array of arrays. This should help weaker models avoid losing track of which positional array element maps to which column. #1 Now depends on mcp>=2.1.1 . This is the first non-alpha release of the plugin. I'm confident it's ready as I've been using it quite a bit myself. Tags: datasette , model-context-protocol

GLM 5.3 Flash makes a black hole Minecraft mod running locally on 4x RTX PRO 6000 WS

saw the post the other day where people said Minecraft clones aren't impressive anymore, because at this point the whole thing might as well be in the training data. so i tried something slightly different, which is asking a local model to write a mod for the real game, using the Fabric API the model is GLM 5.3 Flash (Q4 quant, running on a rented 4x RTX PRO 6000 box). this wasn't done in prompt or a loop, i would ask for changes, then review them and i kept going like that until i was happy wit

LightNav-0: Eliciting VLM Spatial Intelligence for Generalist Embodied Navigation

Embodied navigation requires agents to translate heterogeneous goals and visual observations into actions across tasks, environments, and robot embodiments. Modern vision-language models (VLMs) already encode spatial priors for visual grounding, spatial reasoning, and pointing, but these capabilities are rarely elicited directly for robot control. Existing navigation systems instead rely on task- or embodiment-specific components, fragmenting perception, reasoning, and action while offering limi

Evaluating Multimodal LLMs as Generalist Vision-Language-Action Agents for Drone Control: Commanding, Approaching, Tracking and Searching

Multimodal Large Language Models (MLLMs) are strong perceivers of images and video. We ask how far that reach extends into acting: dropping an MLLM directly into a drone's control loop, with its entire action space declared solely in the prompt. Recent systems approach this setting but increasingly narrow the model's decision-making. We widen it back. We introduce DroneCATS-Agent, an architecture where the MLLM is a swappable component, and DroneCATS, a benchmark treating the model as the indepe

HyperWorld: Hypergraph-Structured State Serialization Improves Learned Textual World Models

arXiv:2609.00002v1 Announce Type: new Abstract: World models enable language-model agents to predict environment dynamics and plan before acting. In text environments, the model must learn symbolic action effects from serialized state descriptions, but the role of serialization structure remains underexplored. We present HyperWorld, a controlled study of state serialization for learned textual world models. We compare raw observations with three symbolic serializations of the same ground-truth s

Agents in the Large: Perception-Centered Architecture for Persistent Agents

Cognitive language agents have achieved substantial progress by equipping language models with memory, tools, and decision-making procedures, enabling agents to reason and act in interactive environments. Existing frameworks largely cast these agents as systems for solving user-specified, bounded tasks. An increasingly important goal is for language agents to provide persistent assistance in long-lived settings where user needs, context, and service procedures persist and change, and to remain u

Recursive Criticality of AI Self-Improvement

arXiv:2609.00137v1 Announce Type: new Abstract: AI is increasingly used in the R\&D process that produces future AI systems. We study the conditions under which this feedback becomes self-amplifying. Our model describes how the rate of AI capability growth depends on baseline research productivity, recursive feedback, and the increasing difficulty of research progress. We derive a recursive reproduction number, $\mathcal{R}_{\mathrm{AI}}$, that determines whether improvements are amplified or da

Handle colleagues who communicate through LLM's

I like AI and use it daily so AI by itself isn't a problem. But I feel like some colleagues use it in a weird/wrong way. I have this one colleague who uses AI to its maximum capability, he is a frontend dev who writes the frontend to an application my team is building. Its all done by AI, and I don't really care. He can do it in whatever way he want's. My problem with his AI usage is that he often makes requests through slack to my team. Either a bug or a feature request. But instead of writing

I-CARE: Analysis of interference-related phenomena in a controllable, diverse and representative unlearning setting for text-to-image models

arXiv:2609.00003v1 Announce Type: new Abstract: Machine unlearning studies the removal of knowledge from an AI model, making the system forget a concept it previously learned. Despite rapid progress in generative machine unlearning, the unintended degradation of semantically related concepts that should have been retained (henceforth, interference) remains poorly characterized and inconsistently evaluated. This paper introduces I-CARE, a methodology that formalizes interference as a first-class

SCAFFOLD: A Large-Scale Structured Dataset of Computer Science Research Figures with Diagram QA and Chain-of-Thought Reasoning Traces

arXiv:2609.00018v1 Announce Type: new Abstract: Computer science papers rely heavily on diagrams: architecture drawings, system flowcharts, and pipeline schematics that often carry more information than the text around them. There is currently no public dataset that pairs this specific kind of figure with captions, context, questions, answers, and step-by-step reasoning, which is exactly what is needed to train a vision-language model to understand them. We present \textbf{SCAFFOLD}\footnote{ a

EM^2Mem: Event-Centric Multimodal Memory for Large Language Models

Multimodal memory offers a scalable interface for long-video question answering, but existing methods often retrieve captions, frames, transcripts, summaries, or graph facts as isolated fragments. Although searchable, such fragments are not generation-ready: language models must reconstruct cross-modal and temporal alignments at inference time, when context is limited and attribution is difficult. We propose EM^2Mem, an event-centric multimodal memory framework that binds heterogeneous evidence
