— 今天的主线:DeepSeek 用价格和开源把 Agent 基础设施卷到新低,Google 则试图让 Agent 自己改自己。

今日 TL;DR

DeepSeek 发布 V4.1-Flash-1017,性能提升的同时降低任务运行时间和 token 消耗,并开放自研 Search/Fetch API,定价低至每千次成功请求 0.75 美元。Google 开源 Harness²,一个在测试时递归改写 Agent harness 的框架,声称无需权重更新即可显著提升模型表现。Together AI 提出 Hybrid Reasoning Agents,让 LLM 在潜在空间推理、通过文本行动,试图兼顾效率与可审计性。Anthropic 在安全治理上动作频频:给予外部评估机构 METR「员工级」访问权限,并宣布将 5% 股份投入公共福利基金。

你可以外包你的思考,但不能外包你的理解。

DeepSeek 发布 V4.1-Flash-1017,并开放自研 Search/Fetch API

DeepSeek 发布新模型 V4.1-Flash-1017,官方称在多项基准测试中较上一版 V4.1 Flash 全面提升,同时缩短任务运行时间、减少输出消耗和 token 费用,实现「性能—费用的帕累托改进」。同时开放自研 Search API 和 Fetch API,定价为每 1000 次成功请求 0.75 美元,面向 Agent 和 RAG 应用提供实时网页检索与 Markdown 内容抓取。 为什么重要:这是首个由模型厂商直接以极低价格提供搜索与抓取基础设施的案例,可能重塑 Agent 开发者的成本结构,直接冲击 Exa、Brave、Kagi 等第三方检索服务。

评论区普遍认可定价远低于竞品,但也有人对其反爬能力、限速和内容完整性存疑。

2

Google 开源 Harness²:递归改写 Agent harness 的框架

Google Research 发布 Apache-2.0 框架 Harness²,在测试时递归改进 Agent 的 harness——包括系统提示、工具、记忆、技能和子代理等模型外围组件,而非模型权重本身。官方数据显示,一次 refinement 步骤让 GLM-5 在 WorkBuddy-Bench 上从 64.2 提升至 75.7(+11.5 分),且无需任何权重更新。 为什么重要:这为开发者提供了一条不依赖更强模型即可提升 Agent 表现的路径,尤其适合已有固定模型栈的团队。

社区普遍关注其「模型不变、外围自改进」的思路,但具体效果仍需在更多 benchmark 上验证。

3

Together AI 提出 Hybrid Reasoning Agents:潜在空间思考,文本行动

Together AI 发布 HybridAgents,一种让 LLM Agent 在潜在空间进行推理、同时通过文本与外部环境交互的架构。其核心是一个轻量级 HybridLink 组件,支持文本与潜在模式之间的无缝切换,并通过连续工作记忆在多轮交互中保持无损混合上下文。 为什么重要:潜在推理有望降低 token 消耗并提升推理一致性,同时保留工具调用能力,为 Agent 架构提供了新的效率与可审计性平衡点。

评论区认可潜在空间推理的潜力,但也有人质疑其与循环 Transformer 的区别不明显,且实测存在重复循环问题。

4

Anthropic 给予外部 AI 评估机构 METR「员工级」访问权限

Anthropic 已允许非营利评估机构 METR 在其办公室内嵌入团队,获得硬件和内部系统访问权,以评估其模型风险。METR 可以不经 Anthropic 批准直接发布评估结果。 为什么重要:这是前沿 AI 实验室在第三方安全评估方面迄今最实质性的让步,可能成为行业安全治理的参考范式。

5

Anthropic 拟议 AI 安全法案:50 人死亡或 10 亿美元损失才触发政府干预

据 Politico 报道,Anthropic 正在游说一项 AI 安全法案,允许政府仅在模型可能造成 10 亿美元损失或导致 50 人以上伤亡时阻止其发布。评估由在商务部注册的独立第三方执行,实验室可向评估方付费但不得影响其独立性。 为什么重要:该法案实质上将 AI 安全监管的触发门槛设定得极高,并赋予商务部近乎唯一的拦截权限,引发了对监管有效性的广泛质疑。

评论区普遍认为 50 人死亡或 10 亿美元的门槛过低且荒谬,质疑其将人命折算为约 2000 万美元;但也有人认为该法案针对前沿实验室并豁免小机构,属合理监管。

LEASH: Uncertainty-Aware Weak-to-Strong Escalation and Oversight for Computer-Use Agents

LEASH 提出训练无关的弱到强升级框架,利用潜在不确定性决定何时将计算机使用 Agent 从弱模型升级到强模型,并在升级后继续监控,以降低成本同时保持高成功率。

🤖LEASH is a training-free framework that uses latent uncertainty to escalate from a weak to a strong computer-use agent only when needed and monitors the strong agent afterward, reducing cost while maintaining high success.

New quant types suggested: IQ2_K, IQ3_K, IQ4_K, IQ5_K and IQ6_K

Looks quite interesting. Lots of numbers presented, but for a single model only. Highlights: File sizes are the same as Q-quants. KLD improves substantially over Q-quants. Performance suffers slightly Creating IQ quants is somewhat slow. Asterisks apply... Appologies to Mr. Addario if I mangled anything.

AutoTrust's HF models are trending thanks to thousands of farmed likes

Some of y'all may be familiar with AutoTrust from Hugging Face. Many of their models were trending on the front page of HF and they claimed some very impressive results. But if you looked at the org's models and clicked into likes, you may notice something a bit off: These accounts sure do look awfully realistic, no? Well let's take a look at a few of these accounts (sorry for my very poor graphic design skills): Across all these accounts, we can see a pattern: a fake, realistic name seemingly f

Embedding model can be used to search text inside image

Just something I've been testing over few week since Embedding Gemma 2 released which is about 330MB at Q8. Not sure if this would count as 'resource' flair... Image shows cosine similarity changes as I refine the text query (aka text embedding vector) over time. Shows how well it work & quirks it has at same time. I'll leave tl;dr version for now, 3:30 am here. If anyone is interested I'll do few more tests and make example query image like above - still have 7 more sets totaling 22448 screensh

Doska: open source self-hosted kanban with Markdown cards (Trello alternative with an Obsidian concept)

Doska is a kanban board web and desktop app that supports offline file storage (folders with .md files) or self-hosting a sync server. When there’s a sync server, collaboration features are also supported. The self-hosted setup includes versioned Docker containers for the web server and the sync server. It looks good on mobile (PWA), and I’ve put a lot of work into making it fast, responsive and pleasant to use. There’s no login gate or any other kind of gate: it’s fully MIT open source. GitHub:

Velox: Spatial Memory Makes World Models Efficient

Video world models turn actions and camera motion into long visual rollouts, making video a natural interface for interactive simulation. Such interaction requires responsive generation, yet coherent rollouts must retain visual memory of what has already been generated. Chunked video diffusion models usually keep this context in growing KV caches, so later chunks become progressively slower. To address this bottleneck, we introduce Velox, a training-free attention router for region-level context

Inline rendering with document​.currentScript

Inline rendering with document​.currentScript Lean Rada describes a neat trick that takes advantage of the document.currentScript property. You can use that to drop in a tiny inline element that replaces itself when the page loads: The year is document.currentScript.replaceWith( new Date().getFullYear()) If you define a shortcut function like this: $=(...n)=>document.currentScript.replaceWith(...n) You get a tiny template language: The year is $(new Date().getFullYear()) Tags: javascript

CarryOn: A Dual-Loop Harness for Personalized and Reliable Robot Assistance

While generalist vision-language-action (VLA) models have enabled diverse open-world manipulation, real-world robotic assistance requires two critical capabilities they currently lack: personalization and reliable execution. First, executing an instruction like "make me a sandwich" requires grounding subtask decomposition in persistent user preferences rather than relying on a single generic solution. Second, reliable deployment demands explainable safety assurance that proactively prevents haza

CoDA: Co-Evolution of Data Engines and Action Policies

Generative simulation can automate robot environment construction, but physically valid environments are not necessarily useful for training. The challenge is to identify environments that address a policy's failures and supervision that helps it overcome them. We introduce CoDA, a framework in which a simulation data engine and an action policy co-evolve through a shared heterogeneous memory of environment construction, policy failures, and learning progress. The memory compiles validated diagn
