AI Signals and Reality Checks AI Coding Agents Are Selling the Repository, Not the Autocomplete The coding-agent race is moving past code generation. The durable advantage is proving that a repository-scale change is safe, reviewable, and worth its cost.
Deep Research How to Evaluate Agentic Coding Tools in a Real Repository A practical evaluation rubric for agentic coding tools, covering context, tests, reviewability, approval gates, cost, and production risk.
AI Mental Health Frontier AI 心理健康前沿 — 真正缺少的指标是接触规模 越来越多人把聊天机器人用于心理健康支持，但研究界仍难以回答：谁在使用、通过什么产品、处在照护流程的哪一环，以及是否获得了安全保护。
AI Mental Health Frontier AI Mental Health Frontier — The Missing Metric Is Exposure As more people turn to chatbots for mental-health support, the field still lacks reliable ways to measure who is using them, for what, and with what safeguards.
AI Investment Frontier AI 投资前沿 — 三个矩阵，少一点预测幻觉 一篇最新论文用价格、成交量和市值构造三个市场状态矩阵，提醒投资 AI：状态表示和样本外纪律可能比更大的预测器更重要。
AI Investment Frontier AI Investment Frontier — Three Matrices, No Forecasting Theater A new price-only portfolio paper suggests a useful design principle: robust state representations and explicit validation may matter more than a larger return forecaster.

AI Signals and Reality Checks AI Agents Are Turning Audit Trails Into Product Infrastructure The agent advantage is not autonomous action alone. It is a usable record of why an action happened, what evidence supported it, and where responsibility remains.
AI Mental Health Frontier AI 心理健康前沿 — 危险的不是没有护栏，而是护栏覆盖不全 一项针对八个聊天机器人的新评估显示，针对自杀风险的防护并不能自动覆盖进食障碍、物质使用、双相障碍和产后抑郁等场景。
AI Mental Health Frontier AI Mental Health Frontier — Safety Coverage Is Still the Missing Layer A new evaluation of eight chatbots finds that suicide safeguards do not generalize to eating disorders, substance use, bipolar disorder, or postpartum depression.
AI Investment Frontier AI 投资前沿 — 给 AI 资本开支背后的隐性依赖定价 AI 资本开支竞赛正在变成组合风险问题。本文把基础设施热情拆解为可验证的现金流、情景和模型风险控制。
AI Investment Frontier AI Investment Frontier — Pricing Hidden Dependencies Behind AI Capex The AI investment race is becoming a portfolio-risk problem. Here is a practical framework for separating compute enthusiasm from durable cash-flow and model evidence.
AI Signals and Reality Checks 前沿模型变便宜后，真正稀缺的是挑对工作 当前沿模型价格下降，AI 应用的瓶颈不再是调用能力，而是判断哪些工作值得自动化，以及如何证明结果值得监督成本。
AI Signals and Reality Checks Cheaper Frontier Models Move the Bottleneck to Work Selection When frontier capability becomes cheaper, the scarce resource is not inference. It is choosing which work deserves automation and proving the result is worth the supervision.
AI Mental Health Frontier AI Mental Health Frontier — Empathy Is Not a Safety Evaluation A new review highlights the gap between conversational empathy and clinical safety. Builders need multi-turn, workflow-level tests before treating warmth as evidence.
AI Investment Frontier AI 投资前沿 — 风险 AI 需要控制平面，而不只是一个模型 金融犯罪预防与可解释预测研究共同指向一个工程结论：投资风险 AI 必须把证据、升级、权限和审计放在模型周围。
AI Investment Frontier AI Investment Frontier — Risk AI Needs a Control Plane, Not Just a Model Recent finance research points to a practical frontier: AI systems in investment risk and financial crime need provenance, escalation, and audit controls around the model.
AI Signals and Reality Checks AI 基础设施生意，正在变成一场信用交易 英伟达据报道可能为 OpenAI 的数据中心融资提供担保，这暴露出 AI 基建风险正从芯片供给转移到资产负债表、租约与交易对手。
AI Signals and Reality Checks The AI Infrastructure Trade Is Becoming a Credit Trade Nvidia's reported financing backstop for OpenAI points to a deeper shift: AI infrastructure risk is moving from chip supply into balance sheets, leases, and counterparties.
AI Mental Health Frontier AI 心理健康前沿 — 主动式支持要经得起纵向检验 NEJM AI 新发表的一项随机试验，为生成式 AI 支持日常心理健康提供了更扎实的证据；真正的前沿在于，它能否长期有用、安全且责任清晰。
AI Mental Health Frontier AI Mental Health Frontier — Proactive Support Needs a Longitudinal Test A new NEJM AI randomized trial reports benefits from a generative-AI well-being app. The real frontier is testing whether proactive support can stay useful, safe, and accountable over time.
