## 不只是协作工具，更是AI时代的“第二大脑” 在AI工具层出不穷的今天，**Liminal** 试图回答一个根本问题：当AI代理（Agent）成为团队的一部分时，我们该如何与它一起工作？ Liminal 将自己定位为“一个为你、你的AI代理和你的团队打造的工作空间与第二大脑”。这意味着它不再仅仅是一个传统的项目管理或笔记应用，而是一个**人机协作**的底层平台。 ### 核心能力：从“记录”到“思考” 与许多只做信息聚合的工具不同，Liminal 强调“第二大脑”的概念。它可能集成了以下关键特性： - **知识管理**：像 Notion 或 Obsidian 一样，你可以自由地记录想法、文档和项目资料。 - **AI 原生集成**：你的AI代理不是外挂插件，而是工作空间中的“一等公民”。它可以读取上下文、执行任务、甚至参与讨论。 - **团队协作**：人类成员和AI代理共享同一个空间，信息流动更加自然。 ### 为什么“AI代理”是关键？ 当前AI工作流的一大痛点是：AI往往被隔离在聊天窗口里。Liminal 的尝试在于，让AI代理直接“住进”你的工作空间，像团队成员一样拥有自己的“视角”和“记忆”。这意味着： 1. **持续上下文**：AI不会每次对话都“失忆”，它能基于整个工作空间的知识做出更准确的回应。 2. **主动执行**：AI可以自动整理会议笔记、更新任务状态，甚至根据你的写作风格起草文档。 3. **透明协作**：人类可以查看AI的“思考过程”（比如它引用了哪些资料），建立信任。 ### 适用场景与行业意义 Liminal 的出现，反映了 AI 行业从“对话式 AI”向“代理式 AI（Agentic AI）”的演进。对于知识工作者、初创团队和远程团队来说，它可能解决以下问题： - **信息碎片化**：将 Slack、邮件、文档、任务管理统一到一个空间。 - **AI 工具孤岛**：不再需要在不同AI工具之间切换。 - **团队知识沉淀**：AI 可以帮助自动生成摘要、关联旧项目，减少重复劳动。 ### 局限与思考 目前 Liminal 尚处于早期阶段，其实际体验取决于 AI 模型的推理能力和工作空间的数据结构化程度。用户需要留意： - **学习成本**：从传统工具迁移需要时间。 - **隐私与数据控制**：将知识交给AI代理，需确认数据存储和权限管理是否完善。 - **AI 可靠性**：AI 代理仍可能出现幻觉或错误决策，需要人类监督。 ## 小结 Liminal 是一个大胆的尝试，它试图重新定义我们与AI的协作方式。如果成功，它可能开启“人机团队”的新范式——不再是“使用工具”，而是“与伙伴共事”。对于关注 AI 生产力工具的用户，Liminal 值得一试。

Researchers tested top image editing models on Hugging Face and found they could easily create explicit deepfakes—and 1,000 image editing prompts show how people use the software.

Cursor says India is now its third-largest market globally and plans to expand local hiring and enterprise sales.

arXiv:2607.22544v1 Announce Type: new Abstract: Visual counterfactual explanations aim to answer "what minimal change to this image would flip the model's prediction?", and are increasingly important as vision models are deployed in safety-critical domains (e.g., medicine). Existing diffusion-based methods can produce realistic edits, but they rely on external classifiers that must work reliably on noisy images, which makes them fragile and hard to deploy for robust explanations. We introduce C-

arXiv:2607.22554v1 Announce Type: new Abstract: Large language models (LLMs) often achieve strong accuracy on benchmarks, yet it remains unclear how reliably they apply this knowledge when the same question is phrased in different but equivalent ways. In this work, we study how model answers change under meaning-preserving paraphrases across factual question answering and mathematical reasoning tasks. Across four benchmarks and 13 models, we find that model outputs frequently depend on the exact

arXiv:2607.22561v1 Announce Type: new Abstract: LLM-as-a-judge has become the standard for automated evaluation, but it suffers from high cost, significant latency, and opaque decisions -- limitations that undermine its scalability and reliability. We address these with a simple, efficient alternative: program distillation. Instead of prompting an LLM at the evaluation time, we distill its decision logic into a committee of programs that score candidates directly. These programmatic judges offer

arXiv:2607.22562v1 Announce Type: new Abstract: Managing long-context dependencies remains a primary bottleneck in LLM agents, as redundant and irrelevant information can degrade multi-step reasoning. Strategic Forgetting for Agent Memory Systems (SF-AMS) is proposed as a framework for maintaining compact high-utility memory by modeling the long-term importance of memory units. SF-AMS replaces static retrieval and heuristic decay with a utility-driven survival mechanism that updates memory impor

arXiv:2607.22555v1 Announce Type: new Abstract: Medical diagnosis is a multi-stage process: extract facts, consult knowledge, generate a differential analysis, and select the best diagnosis with explanations. Frontier LLMs are strong generalists, but single-shot prompting often yields brittle diagnostic reasoning. We present the DeepLens Diagnosis Agent, a five-stage harnessing pipeline (combining model capabilities with disciplined process constraints) centered on a small medical reasoning mode

arXiv:2607.22556v1 Announce Type: new Abstract: Continual learning (CL) is essential for small language models (SLMs) to adapt to evolving real-world needs in resource-constrained deployments. However, directly updating their limited parameter space causes catastrophic forgetting. While memory-based methods naturally address this by decoupling knowledge retention from parameters, existing approaches designed for large language models (LLMs) rely on abundant storage and strong in-context reasonin

arXiv:2607.22548v1 Announce Type: new Abstract: Data centers and their compute nodes require accurate and flexible digital twins capable of modeling the complex interplay of workloads, environmental parameters, and physical metrics. Current machine learning approaches for HPC and its telemetry typically rely on a static subset of anonymous, fixed-position sensor variables tailored to single tasks. Consequently, these models become obsolete when target tasks change or sensor metrics vary. We prop

arXiv:2607.22549v1 Announce Type: new Abstract: Hybrid quantum-classical protein structure prediction depends strongly on Hamiltonian penalty weights, yet existing lattice-based workflows typically fix these coefficients by hand and evaluate only very short fragments in simulation. We present QFoldAgent, a closed-loop multi-agent framework for 5-residue tetrahedral-lattice folding in which a design agent proposes sequence-conditioned penalties, a VQE-based quantum-classical pipeline optimizes th

美国堪萨斯州埃姆波利亚市一名高中物理教师因在市政会议上鼓掌支持反对数据中心的居民，被四名警察当众逮捕。事件起因于一项占地1000英亩的数据中心项目“弗林特山数字园区”的争议。会议期间，主持官员明确禁止鼓掌、打响指等行为，称“不尊重发言者”。当一名发言者结束评论后，物理教师卢克斯·克拉里奇鼓掌六次，随即被警察戴上手铐带离。克拉里奇表示此举“只是不便”，不会阻止他继续发声。其兄弟和在场居民批评政府过度使用武力，侵犯宪法第一修正案权利。此事件折射出民众对大型数据中心建设的不满与地方治理的紧张关系。

Anthropic founder and CEO Dario Amodei made his views clear about open-weight models and China's growing AI capabilities.

Moonshot AI released open weights for Kimi K3 today and it's live on Telnyx Inference. The architecture and Moonshot's own benchmarks are in their technical blog. This post is about running it on Telnyx.What we are adding: K3 is now available via the Telnyx Inference API, hosted on GPUs th

Microsoft says tools cost less than competing ones and outperform them, too.

Companies without their own models — or without a layer of AI infrastructure known as AI gateways to separate their prompts from the model itself — will be in trouble, Nadella says.

The issue appears to have originated from Claude’s “share chat” feature, which allows users to create links that enable anyone with the assigned URL view a conversation or project.

Google's and Reddit's use of DMCA to fight web scraper is bizarre, expert says.

The screwup shows how tricky it can be to stop web crawlers from making ostensibly private conversations with AI chatbots entirely too public.

Manufacturers keep putting more and more memory into new phones, and we're the ones paying for it.
