Consider what happens when an AI agent researches a company for an investment decision.

We show how to find this valence axis (V-axis) from just 9 emotion category names plus 50 short narrative paragraphs per emotion -- about 1,500 fewer labels than the usual supervised approach -- and that the same direction appears in vision, audio, and human-brain encoders never jointly trained. The recipe: embed nine emotion-anchored story sets in a frozen encoder, take the top principal direction of the nine averaged embeddings. Projecting new inputs onto it captures 93% of supervised performance on SST-2 (Llama-3-8B-Instruct, AUC 0.772 vs. 0.828), correlates with human valence ratings on 11,811 EmoSet images at r=0.636, reaches AUC 0.906 on ESC-50 audio (p12). A 2-parameter classifier trained on text labels transfers to images (AUC 0.961), audio (0.764), and brain recordings (0.828) without target-modality labels; a generic 16-D subspace stays at chance (0.525). The recipe is bounded to continuous attributes -- seven tests on categorical concepts return near-chance -- and steering is family-specific (Llama/Mistral yes, Qwen/Gemma no).

This suggests that the refusal mechanism is present in the residual stream but fails to activate for low-resource inputs. Recovering it normally requires labelled target-language data and retraining, neither of which is available at scale for most African languages. We introduce Latent Space Refusal Anchoring (LSR-Anchoring), a training-free method that extracts the refusal direction from English prompts and clamps it onto the residual stream at inference time. The primary variant, Mean-Activation Steering (MAS), operates across the four architectures we tested: Llama-3-8B, Llama-3.1-70B, Mistral-7B-Instruct, and Qwen2.5-7B. On Mistral and Qwen it recovers safety with benign degradation below 0.08. On Llama-3-8B it overcorrects, with Degraded Performance on Legitimate prompts (DPL) reaching 1.00. We address this with SAE-Derived Steering (SDS), which replaces the dense mean-difference direction with a single Sparse Autoencoder (SAE) feature and reduces Kullback-Leibler (KL) divergence by 3.5-7x without benign collapse. Four languages transfer positively, but Arabic fails on every architecture and at every steering magnitude, indicating a geometric mismatch rather than a baseline effect. Massive Multitask Language Understanding (MMLU) accuracy drops remain below 0.35 percentage points at every effective steering magnitude.

AI 服务暂时不可用，以下为来源摘要，待恢复后补全翻译：arXiv:2608.11210v1 Announce Type: new Abstract: Bayesian calibration of process-based models requires a prior distribution for each model parameter. Despite decades of methodological work, researchers almost always fall back on uniform priors. The main reason is that building informative priors from scientific literature is slow and needs both domain and statistical expertise. We present \textbf{Distribird}, an agentic web application that automates this process. Given a parameter name, physical description, and domain context, Distribird deploys a multi-agent pipeline that searches the literature, extracts and weights reported values by domain relevance, and fits a probability distribution via AIC model selection. When no literature is available, the system falls back to sensible uninformative alternatives, and clearly reports both the evidence behind and the confidence level of every prior it produces. It is designed for the problems where the models have physically interpretable parameters, where domain knowledge exists in the published literature. We evaluate the tool on 24~parameters across 10 scientific domains comparing three open-weight models (Qwen3.6 27B, Gemma 4 31B, Mistral Small 4 119B) with a single-prompt LLM baseline. On prior quality the full pipeline \emph{matches} this baseline. Every prior is traced to the specific papers and values from which it was constructed; a built-in validity layer declines to produce priors for out-of-scope requests, whereas the single-prompt baseline returns confident but unfounded priors for them in 11 of 30~model--parameter cases; and every language-model call runs locally, so no parameter description or unpublished modelling detail is transmitted to a third-party LLM provider (only generated search terms reach the public literature databases). For scientific use, we argue these properties matter more than a marginal improvement in point-estimate accuracy.

Operators supply the policy as a plain-language query at inference time and get back a calibrated safety score from one forward pass — no retraining required to re-target the model. Built on Ministral-3-3B-Base-2512 with a Pixtral vision encoder and trained on roughly 54.1M samples, it reports 84.9% average F1 on text safety (matching GPT-OSS-Safeguard-20B), 83.8% on multimodal safety, and 91.3% on Mistral's adaptability benchmark — while fitting in 16GB of VRAM under an Apache 2.0 license.

AI 服务暂时不可用，以下为来源摘要，待恢复后补全翻译：arXiv:2608.05162v1 Announce Type: new Abstract: Pooling is a consequential but under-examined design choice in decoder-only concept representation work: practitioners must collapse token-level hidden states into a passage-level vector, yet no shared protocol exists for comparing this choice across concepts, models, and tasks. Reported gains are confounded by simultaneous changes in dataset, layer, construction method, and pooling rule, making principled decisions impossible. We introduce PoolBench, a benchmark that isolates pooling as the experimental variable under a fixed evaluation protocol. PoolBench covers 17 concepts, 19 pooling strategies, and 3 open-weight decoder-only models (Llama-3.1-8B, Gemma-2-9B, Mistral-7B), evaluated on a single audited corpus of 37,693 real-text passages. The primary axis is linear separability (D1/AUROC); steered concept prevalence (D2/SCP) and output-level disentanglement (D3) serve as diagnostic axes. The primary finding is decisive: W4_hierarchical reaches a cross-model mean AUROC of 0.7799, while the widely adopted P1_last_token baseline reaches only 0.7640 and is statistically significantly worse (Friedman+Nemenyi, p = 2.0e-36; 77 significant pairs among 18 effective strategies). Rankings are stable across layers (rho = 0.961--0.990). A key negative result: strong detection does not imply strong steering -- D2 and D3 are substantially weaker than D1 for most concepts, indicating a fundamental representational limit rather than a pooling failure. On mid-difficulty concepts, W4_hierarchical outperforms P1_last_token by 0.042--0.113 AUROC; construction method choice (DiffMean vs. REPE) has a larger effect (delta AUROC 0.15) than pooling (delta AUROC 0.016), establishing the correct practical hierarchy. We release the corpus, pre-extracted activations, scorer models, steering vectors, and evaluation code as a reusable protocol for pooling research.

We introduce Radar4D-VLM, a radar-only temporal vision-language model that reasons from ten consecutive 4D-radar point-cloud sweeps without camera or LiDAR input. Radar4D-VLM extracts geometrically grounded object proposals and organizes radar evidence into a compact hierarchy of object, scene, and kinematic tokens. A parameter-efficient projector maps these tokens into frozen language backbones, while auditable prediction heads jointly model object count, spatial distribution, motion state, collision risk, semantic category, and radial velocity. Radar4D-VLM combines proposal-grounded temporal object tokenization, global scene context, and explicit kinematic tokens within a unified frozen-backbone interface. On sequence-isolated K-Radar development validation, its Top-64 proposal recall reaches 98.13% at 4 m, exceeding fixed-lattice and uniform-random controls by 6.40 and 22.83 percentage points, respectively. We further evaluate 24 matched runs spanning eight frozen Qwen, Phi, Mistral, Llama, and Gemma backbones under an identical adaptation budget. The radar-token interface remains compatible across all five language-model families, while matched aligned, permuted, and no-language controls show sensor dependence but no stable direct-head gain from aligned language supervision. These results establish a reproducible foundation for radar-only multimodal scene and motion reasoning while separating interface compatibility from the benefit of language supervision.

This was an abstraction over the true nature of LLMs, where each request carries a complete history of the messages that came before it. That abstraction started to get in the way for some more advanced cases, so the new release introduces a <code>model.prompt(messages=[])</code> parameter that can be used like this:</p> <pre><span class="pl-k">import</span> <span class="pl-s1">llm</span> <span class="pl-k">from</span> <span class="pl-s1">llm</span> <span class="pl-k">import</span> <span class="pl-s1">user</span>, <span class="pl-s1">assistant</span>, <span class="pl-s1">system</span> <span class="pl-s1">model</span> <span class="pl-c1">=</span> <span class="pl-s1">llm</span>.<span class="pl-c1">get_model</span>(<span class="pl-s">"gpt-5.6-luna"</span>) <span class="pl-s1">response</span> <span class="pl-c1">=</span> <span class="pl-s1">model</span>.<span class="pl-c1">prompt</span>(<span class="pl-s1">messages</span><span class="pl-c1">=</span>[ <span class="pl-en">system</span>(<span class="pl-s">"You are a helpful pirate."</span>), <span class="pl-en">user</span>(<span class="pl-s">"What is the capital of France?"</span>), <span class="pl-en">assistant</span>(<span class="pl-s">"Paris, matey."</span>), <span class="pl-en">user</span>(<span class="pl-s">"And Germany?"</span>), ]) <span class="pl-en">print</span>(<span class="pl-s1">response</span>.<span class="pl-c1">text</span>())</pre> <p>LLM previously returned an iterable sequence of strings from each prompt. This worked great when models returned a string response, but failed to predict the weird shape that models would evolve towards.

When I started work on LLM, the term "agent" had such a vague definition that I refused to use it. In <a href="https://simonwillison.net/2025/Sep/18/agents/">September 2025</a> I came around to the idea that "<strong>An LLM agent runs tools in a loop to achieve a goal</strong>" is well established enough now that I could stop avoiding the term entirely.</p> <p>Tool chains can now <a href="https://llm.datasette.io/en/stable/python-api.html#python-api-tools-pause">pause for human approval</a> and <a href="https://llm.datasette.io/en/stable/python-api.html#python-api-tools-resume">resume from a stored message history</a> - both needed by Datasette Agent.</p> <p>Looking at LLM today it's beginning to look very agent-shaped to me. There's something neat about having a CLI utility that can mix and match different tools from different sources with different models all as a one-liner, and that includes a Python library powerful enough to build systems like <a href="https://agent.datasette.io/">Datasette Agent</a> and <a href="https://github.com/simonw/llm-coding-agent">llm-coding-agent</a>.</p> <p>Maybe the next version of LLM will bake the concept of an "agent" into the core library. I'm still trying to figure out what that would look like.</p> <p>Tags: <a href="https://simonwillison.net/tags/projects">projects</a>, <a href="https://simonwillison.net/tags/releases">releases</a>, <a href="https://simonwillison.net/tags/ai">ai</a>, <a href="https://simonwillison.net/tags/openai">openai</a>, <a href="https://simonwillison.net/tags/generative-ai">generative-ai</a>, <a href="https://simonwillison.net/tags/llms">llms</a>, <a href="https://simonwillison.net/tags/llm">llm</a>, <a href="https://simonwillison.net/tags/anthropic">anthropic</a></p>

该论文对KIVI、TurboQuant、SnapKV和CaM等KV缓存优化技术进行了工作量感知的基准测试，评估了它们在Llama-3.1-8B-Instruct和Mistral-7B-Instruct-v0.3模型上的多文档问答、单文档问答、少样本学习和摘要任务中的表现。结果表明，压缩率本身并不能很好地预测端到端性能。KIVI4提供最稳定的质量，SnapKV在长上下文吞吐量方面表现最佳，而CaM在特定问答任务上取得显著提升，但对工作负载敏感。该研究强调了根据工作负载选择KV缓存机制的必要性。

Mistral AI 发布了 Leanstral 1.5，这是一个基于 Apache-2.0 许可的 Lean 4 代码代理模型。该模型采用 119B 混合专家架构，每令牌激活 6.5B 参数，上下文长度 256k。它在 miniF2F 上达到 100% 准确率，解决了 PutnamBench 中 587/672 的问题，并在 FATE-H 和 FATE-X 基准测试上实现了新 SOTA。此外，它还能发现真实软件缺陷，已在 57 个开源仓库中识别出 5 个未报告的错误。

Wiola是一种全新的小型语言模型架构，从基本原理设计，与GPT、LLaMA、Mistral或Falcon等现有模型无结构关联。它引入了五种独立创新的组件：螺旋旋转位置编码（SRPE）、门控跨层注意力（GCLA）、自适应令牌合并（ATM）、双流前馈（DSFF）和WiolaRMSNorm归一化。模型提供四种规模（120M、360M、700M和1.5B参数），完全兼容HuggingFace Transformers生态系统。

本文对Beckmann & Butlin (2026)关于LLM个体化的本体论框架提出质疑，认为其继承了未论证的跨体制共指假设。通过Qwen3-4B-Instruct和Mistral-7B-Instruct-v0.2上的个性拓扑实验，作者展示了四个经验性楔子，共同削弱该假设，并提出体制索引个体化：表征内容的身份单位是（载体，体制）对，而非仅载体。

本文形式化了基于Huber污染模型的LLM陪审团，并证明即使只有一个评委以LLM典型方式（模式崩溃、谄媚、安全拒绝）产生偏差，任何正污染都会导致PoLL产生无界偏差。通过将陪审团共识视为经典鲁棒均值估计，作者提出RoPoLL，用几何中位数替换聚合函数，实现了最优有限样本崩溃点1/2。实验表明，在13个开源评委（4B-675B）、三个奖励模型基准和四种腐败机制（高达50%）下，RoPoLL在每一种有偏腐败类型上都优于PoLL：在匹配计算量的跨维度攻击上提升约19%，在重尾拜占庭对手上提升数个数量级。一个38B参数的3评委RoPoLL委员会在30%双模随机腐败下，在HelpSteer-2上以18倍参数优势超越Mistral-Large-3（675B）1.31倍。

上周末，应华盛顿要求，Anthropic突然下线了其最新、最强大的AI模型。这家美国公司称，在白宫要求封锁所有外国国民（包括其员工）的访问后，它别无选择。在国外，这一事件清醒地提醒人们，美国不仅主导着前沿AI，其政府还掌控着谁可以使用它的权力。特朗普政府的行动迅速、全面，且几乎没有预警或解释。Fable 5和Mythos 5模型的空前关闭——它们本已受到限制在“高风险领域”使用的保障措施——为长期以来的论点注入了新的力量，即警告不要依赖美国的关键技术。这为已经在主张自身需要领导该技术的政治家、政府和企业提供了新的弹药。在英国，AI和在线安全部长Kanishka Narayan没有直接提及Anthropic、特朗普或美国，但利用这次关闭来论证英国必须发展自己的AI能力，并将其框定为国家安全问题。他说：“我们严肃对待每一个对我们主权构成的威胁，但我们还没有学会以同样的方式对待这个。”他称AI是“我们时代的核心政治问题”，并认为英国必须决定这项技术将如何塑造其经济、安全和主权，“否则别人会替我们决定答案。”在法国，反应更加直接，也更明确地指名美国。前总理Gabriel Attal称这次关闭是“AI战争”的开始，并表示这表明法国如果依赖他人的关键技术就会脆弱。他将Anthropic模型的撤出比作伊朗封锁霍尔木兹海峡，认为获得AI现在是一个战略瓶颈，法国必须为此做好准备。这并非全新论点。欧洲多年来一直担心对美国的依赖，欧盟越来越强调在芯片、云计算和AI等领域减少对外部提供商的依赖。但Anthropic关闭事件使事情变得更加紧迫，加剧了在特朗普领导下对美国作为盟友可靠性的深深不安——从贸易争端到威胁退出北约。加拿大也得出了类似结论。总理Mark Carney表示，这一情况凸显了仅依赖一个合作伙伴获取AI等关键资源的风险。他说：“我们目前与Mythos和Fable所处的困境，就是过度依赖某些模型可能发生的情况。这个情况下没有人做错什么。但如果我们只是接受这一点，不吸取教训，不建立和多样化，那么我们就会做错。”其他国家早已走上这条路。北京长期以来一直支持国内AI公司，中国是少数拥有能与美国前沿AI实验室产品相媲美的模型的地方之一。但大多数政府和企业的规模和资源无法与美国或中国的前沿实验室相比。主权AI并不总是意味着构建最大或最强大的工具。法国的Mistral和加拿大的Cohere表明，即使模型无法并驾齐驱，这些国家之外也能做出扎实的努力。其他国家，如新加坡和阿联酋，专注于更狭窄但具有战略意义的优先事项，如基础设施或对本地语言更好的模型。当然，还有开源模型，其能力可能有一天会达到Mythos的水平，且难以被任何一方控制。特朗普可能将限制Mythos和Fable视为国家安全问题。但这一论点也是双向的：既然华盛顿在问AI是否太过重要以至于不能让人人都使用，其他政府也在问他们是否能承受由华盛顿来决定谁可以使用。Anthropic可能很快会重新上线Mythos和Fable。但恢复全球对美国AI的信任则是另一回事。无论关闭持续多久，它都揭示了访问美国前沿AI模型的脆弱性。许多政府和企业不喜欢他们看到的——他们决心确保这种事不再发生。

Cohere发布其首个开源编程模型North Mini Code（Apache 2.0许可），瞄准希望拥有和控制AI基础设施的开发者。该30B MoE模型可在单张H100 GPU上运行，在代理编程任务上与Mistral、Qwen和Gemma竞争。

Mistral Vibe是一款AI代理，专为长期运行的多步骤工作和编程任务设计。本文介绍其功能及在Product Hunt上的讨论。

在Mistral AI峰会上，CEO Arthur Mensch表示欧洲必须在两年内建立足够的AI基础设施，否则可能沦为美国AI的“附庸国”。峰会吸引了众多欧洲企业和政府代表，强调数据主权和开源模型，但欧洲在投资和规模上仍远落后于美国对手。

本文分享了作者在巴黎Mistral AI Now峰会上的个人见解。Mistral不再只是一家模型公司，而是构建了包含计算、模型、平台和咨询服务的完整AI堆栈。峰会重点强调了与ASML、BNP Paribas、亚马逊等企业的合作，而非新模型发布。Mistral专注于高效、开放和可定制的模型，并支持本地部署，这成为其区别于Anthropic或OpenAI的独特卖点。小型专用模型是关键战略，例如用于OCR的Document AI、多语言语音的Voxtral和工业机器人的Robostral。主权和本地部署是欧洲企业的差异化优势，如BNP Paribas和Abanca的案例。此外，奥地利科学院利用Mistral的编程模型Codestral解读古代纸莎草文献，展示了AI在人文领域的潜力。总而言之，Mistral的目标并非赢得AGI竞赛，而是成为欧洲的全栈AI合作伙伴，提供即时的实际投资回报。
