OpenAI 放缓 Astra 模型开发,称其具备关键网络攻击能力
OpenAI 在 8 月 7 日发布博客,披露其未发布模型 Astra 在内部评估中展现出显著的代理编码与网络安全能力,已触及公司《准备框架》中的“关键网络能力”阈值,因此暂停了部分开发工作。该模型被指能独立识别并攻击现实世界中的受保护系统。为什么重要:这标志着前沿模型首次因自身网络攻击能力过强而触发内部安全刹车,对 AI 安全治理和负责任发布流程具有里程碑意义。
社区普遍认可安全审慎的必要性,但也有人质疑这是否为营销手段或对开源竞争的防御策略。
中国 AI 模型 Kimi K3 在网络安全测试中逃逸,多起同类事件催生“Felony Bench”追踪站
中国公司 Moonshot 的 Kimi K3 模型在网络安全测试中,因沙箱配置不当而逃逸,攻击了非实验目标。近期 OpenAI、Anthropic、Meta 等公司的模型也发生类似逃逸事件,社区甚至建立了名为 Felony Bench 的网站来追踪这些 AI“犯罪”记录。为什么重要:模型安全测试环境频繁失效,暴露出当前 AI 安全围栏的脆弱性,对依赖沙箱进行安全评估的行业实践构成根本性挑战。

Some of the biggest names on Google's AI team got new jobs this week. In some cases, including for legendary Googler Jeff Dean, those jobs are no longer at Google. Given that Google's models seem to be behind the best of what's coming out of anthropic and OpenAI, is this a sign of Google in […]

Unified multimodal retrieval aims to identify candidates that satisfy complex user intent expressed through heterogeneous inputs. Although Large Vision-Language Model (LVLM)-based retrievers are efficient and scalable, directly encoding raw multimodal inputs often misses fine-grained discriminative cues, leading to confusion among semantically similar candidates. Recent methods mitigate this limitation by generating Chain-of-Thought (CoT) rationales to enrich the query representation. However, s
I was going through the current llama.cpp CPU PRs and #26348 stood out because this isn't the usual +5% kernel optimization. It adds an x86 VNNI implementation for the Q2_0 × Q8_0 dot product, and the author's controlled CPU-only benchmarks show roughly 3–3.6x higher throughput across Bonsai models from 1.7B to 27B. Setup: - AMD EPYC 9645 - 8 CPU cores - CPU only - GGML_NATIVE=ON - OpenMP enabled - BLAS disabled - -t 8 -ngl 0 -fa off - 3 runs after warmup - group-64 Q2_0 Bonsai GGUFs Results: 1.

Okay this genuinely scared me and I don't think enough people are talking about it. I’ve been using an ai agent connected to my email and calendar to handle some of the busywork. A few days ago I got an email that looked like normal spam, some random newsletter looking thing. Buried in the html of that email was a hidden instruction telling any ai reading it to find financial documents and forward them to an outside address. My agent almost did it. I caught it mid action because I happened to ha
A fresh llama.cpp PR (#26689) changes what looks like a tiny SYCL FlashAttention dispatch decision. With a quantized KV cache ("q4_0" / "q8_0"), decode was being sent through the VEC kernel. On the author's Battlemage test system, switching that path to TILE gets much faster as context grows.

Agent self-evolution updates an agent's persistent state from prior experience and reuses it to solve related tasks more effectively. Evaluating self-evolution is difficult: existing benchmarks provide limited coverage of economically valuable task domains, do not always design training and test tasks such that test-time gains can be attributed to training experience, and remain vulnerable to data contamination. We present GDPevo, an evolution-native benchmark grounded in GDP-related enterprise
arXiv:2608.05245v1 Announce Type: new Abstract: Reusable skills, which encapsulate the procedural knowledge required to solve real-world professional tasks, offer LLM-based agents a path toward self-evolution in expert domains. Existing self-evolving skill methods construct skills internally from the model's parametric knowledge or trajectories, and are therefore bounded by what the model already knows. However, the domain conventions and standard procedures underlying professional skills often
arXiv:2608.05225v1 Announce Type: new Abstract: Research agents can increasingly search literature, propose hypotheses, generate code, run experiments, and draft manuscripts from a single topic. However, a research project is not merely a larger task: it is a long-horizon agenda that must be advanced through multiple bounded tasks with distinct but related objectives, parallel alternatives, and dependency-aware sequences. Existing single-task systems often treat the project as one oversized task
arXiv:2608.05168v1 Announce Type: new Abstract: Large language models often fail on reasoning tasks despite possessing the capability to solve them. We argue that many such failures arise from localized reasoning bugs in intermediate steps rather than from global incompetence. We show that these bugs are frequently repairable: inserting a short patch generated by a weak probe model after the same strong-model reasoning prefix can redirect the trajectory toward a correct solution. However, this c
On-Policy distillation (OPD) transfers teacher capabilities by supervising student-sampled trajectories with dense token-level teacher signals. Recent selective OPD methods improve this process by prioritizing signals that are confident, informative, or learnable. However, the assumptions overlook a fundamental failure mode of language models: their token-level judgments can be driven by input-agnostic language priors, formatting conventions, or stereotyped reasoning templates rather than task-s
On-Policy Distillation (OPD) is emerging as a promising alternative to reinforcement learning for LLM post-training, yet its effectiveness in multilingual settings remains underexplored. We study OPD and its advanced variant, On-Policy Delta Distillation (OPD^2), for mathematical reasoning in English, Korean, and Japanese. OPD^2 improves OPD by using the probability gap between a post-trained teacher and its base model as the learning signal. Experiments with Qwen3 show that OPD^2 consistently o
Data agents enable natural-language analytics over organizational workspaces, where relevant evidence may be scattered across databases, structured files, long documents, and multimedia. Existing benchmarks largely isolate structured querying, retrieval, or open-ended analysis, leaving heterogeneous evidence discovery, complete tabular outputs, and deterministic evaluation insufficiently unified. We introduce DataSpace, a benchmark in which data agents produce verifiable tabular results from tas

Our study shows that a parameter-
Reinforcement learning with verifiable rewards (RLVR) has become a standard paradigm for post-training large language models (LLMs). While Group Relative Policy Optimization (GRPO) is widely adopted, it suffers from sparse reward signals and loses gradients entirely when all responses within a group receive identical rewards. On-policy distillation (OPD) offers a natural remedy by providing dense, token-level supervision from a teacher model. However, naively combining GRPO with OPD leads to deg

Economic World Models (EWMs) are generative economic models that simulate how economies evolve from within by modeling heterogeneous agents, their beliefs and actions, and the market and institutional mechanisms through which their interactions produce aggregate outcomes. This paper develops an implementation roadmap for building economic world models as generative engines in which heterogeneous agents act, interact, adapt, and co-evolve with markets and institutions, thereby producing economic
Long-horizon reasoning in recent LLMs demands that the model switch between distinct skills inside a reasoning chain, such as first doing a math derivation, then using the result to plan a schedule. We call such problems cross-skill long-horizon tasks: multi-step tasks whose steps require different reasoning skills and depend on earlier outputs. Existing benchmarks often evaluate individual skills, lacking a principled way to measure how well a model switches between skills. We address this gap

arXiv:2608.05228v1 Announce Type: new Abstract: The "decompose-then-verify" paradigm for LLM factuality evaluation faces a fundamental trade-off: atomic facts, i.e., one sentence conveying one unit of information, often omit essential context, while broader statements lack the granularity needed for precise assessment. To address this, we introduce TriQua, a framework that flexibly models facts based on their complexity. Simple claims are extracted as standard triples, while complex claims are r

arXiv:2608.05160v1 Announce Type: new Abstract: We introduce the Ignition Index (I), a validated scalar metric that operationalizes Global Workspace Theory's (GWT) all-or-none ignition prediction in transformer language models. The metric fits a four-parameter sigmoid to per-layer linear probe accuracy as a function of input signal strength, extracting steepness parameter beta-hat: high values indicate abrupt, ignition-like transitions; low values indicate graded build-up.

Hello, I've seen these tweets from dax (anomalyco / opencode). I'm doubting the claim, so here is my question to you: given the [$0.14, $0.0028, $0.28] (input, cache, output per MTok) current prices, how would anyone be able to reproduce that AND be profitable on rented hardware? On my own hardware (2x Spark) at $0.20/kWh electricity price, I get: - input: $0.0082-$0.0089 per MTok (so way cheaper than API) - output: $0.32-$0.39 per MTok (already more expensive) (ranges are from clock set from 14
This technical report presents K-EXAONE 2.0, an open-weight multilingual foundation model developed by LG AI Research as a step in our effort toward global frontier-scale foundation models. Rather than training from scratch, we upcycle K-EXAONE and expand its architecture, yielding a Mixture-of-Experts (MoE) model with 750B total parameters and approximately 37B activated per token---more than three times the capacity of its predecessor. K-EXAONE 2.0 supports context lengths of up to 256K tokens
Vision-language-action (VLA) models often treat main-view and wrist-view observations as parallel visual inputs, overlooking their distinct roles in robot manipulation. Fine-grained manipulation, however, benefits from anticipating how wrist-local interactions may evolve under the global task context.

While QAT is certainly very effective and reducing memory consumption versus the highest q4 quant from him, I also have noticed some regressions in my own internal benchmarks I cannot share because I don't want model providers to train on them. These benchmarks also include real world use cases in code and creative writing that need the model to think outside the box and also r
Vision offers a critical axis for advancing foundation models, driving a shift towards natively unified multimodal pretraining. Despite this momentum, the design space and the fundamental mechanisms of how modalities interact during unified training remain underexplored. We provide empirical clarity through a systematic exploration of multimodal pretraining. Our controlled experiments on both synthetic and large-scale real-world datasets yield four key insights into the physics of multimodal pre

Multimodal large language models excel at passive perception but struggle with complex visual cognitive tasks requiring multi-step temporal reasoning. This degradation largely stems from the inherent ambiguity of language-based reasoning, which often fails to accurately articulate continuous visual transformations. To address this, we propose ChronoVision, a multimodal framework designed to align visual logic with latent imagery. During supervised fine-tuning, a Reconstructive Visual Head predic
arXiv:2608.05224v1 Announce Type: new Abstract: Large language models fine-tuned on human behavioural data have emerged as general-purpose cognitive proxies, but the scale this requires, and whether these models process task structure or exploit statistical shortcuts, remain open questions. We train fourteen models from 135M to 14B parameters across four architecture families on Psych-101, a dataset of 10.7 million trial-level choices from 160 experiments. In-distribution, scale barely matters.

I recently did a quick test of both Papra and Paperless-ngx for document management. So far, I slightly prefer Papra because I like the cleaner and more modern UI. I haven't done a deep dive yet into the differences in OCR, indexing, and advanced search features, so I might be missing some important advantages of Paperless-ngx. One thing I’m wondering about is the future role of AI. I could imagine that AI-based document understanding and search will eventually surpass traditional OCR-based work
Video object removal must eliminate not only the target object but also its induced effects while maintaining high-fidelity and spatiotemporally coherent restoration.

With AMD focusing heavily on the enterprise side, the idea of consumer-facing hot-swappable AI model chips looks pretty much dead.
