Everybody's pretty comfortable right now with what they see in front of them. That doesn't seem to be any significant tail risk that we should be factoring into our thinking this morning. Iran is not likely to respond in a significant way that's going to disrupt global trade.Is that the right way of looking at this. I think it is the correct way to trade this until we get a fresh development. I don't think markets experts should pretend to be geopolitical experts.And, you know, all macro traders become armc ...

PR-TELLME团队 投稿 量子位 | 公众号 QbitAI 大语言模型（LLM）能力提升引发对潜在风险的担忧，洞察其内部"思维过程"、识别危险信号成AI安全核心挑战。 当前主流用外部"黑盒"监控模块解读模型表征，此类方法如"隔靴搔痒"：独立于模型，解读逻辑不透明、结果可信度低，且对数据分布变化敏 感、适应性差，难触推理本质，无法满足监控需求。 上海人工智能实验室 和 上海交通大学的研究团队提出创新解决方案——TELLME (Transparency Enhancement of LLMs without External modules)。 该方法摒弃了复杂的外部监控模块，通过"表征解耦"技术，直接提升大模型自身的内部透明度。 破局新思路：从外部监控转向内在透明 其核心理念是：让模型关于不同行为（尤其是安全与不安全行为）的内部"思维语言"（表征）在空间中清晰分离、泾渭分明。这不仅为模型监 控开辟了更可靠、更简单的途径，还意外地提升了模型输出的安全性。 引入对比学习损失（如InfoNCE Loss）作为核心驱动力。该损失函数促使模型将语义/风险相似的问题表征拉近聚合，同时将不同（尤其是安 全与不安全）问题的 ...

If you had asked anybody before this evening how Wall Street would react after the US decided to directly attack Iran, I'm guessing the thought would be more severe than this. I think that was the thought coming in. But remember, we had a taste of this when Israel first struck Iran back late June 12.Here in the United States. And I think the playbook that is going to play out tonight and into Monday could potentially be a repeat of that, a big knee jerk reaction where risk assets get sold off, haven assets ...

DPO 相 对 PPO 真的有优势吗？2. 如何让 PPO 也很能刷榜呢？ DPO 的缺陷 在调教 PPO 的时候，一种常见的现象是语言模型发现了奖励模型的缺陷，而构 ...

Group 1 - W. P. Carey (WPC) has experienced stagnation in stock performance for over a decade, which may deter some investors, but the company has undergone significant transformation [1] - The company is now positioned as a potential investment opportunity due to its strong balance sheet and management team, focusing on sectors with long-term growth potential [1] - Julian Lin, a financial analyst, emphasizes the importance of identifying undervalued companies with secular growth, which aligns with WPC's current strategy [1] Group 2 - The investment approach combines growth-oriented principles with strict valuation criteria, aiming to provide a margin of safety for investors [1] - Exclusive features offered include access to high-conviction stock picks, comprehensive research reports, real-time trade alerts, and macro market analysis [1]

Does it worry you that from the reporting it seems like you know these companies the AI Frontier Labs not all of them but some they've raised billions of dollars there is a pressure to deliver to investors. There are reports that safety is becoming less of a priority as market pressure makes them go and ship without the typical reviews. Yeah, I think it's definitely a concern like we might be facing a tragedy the common situation where obviously all of us want our society and civilization to survive.Look, i ...

[Music] Gold is on a tan 25, up nearly 30% so far this year, torching stocks and bonds as investors scramble for a safe haven watching the dollar head lower. I'm Jared Blickery, host of Stocks in Translation. We're going to start here with a century of gold in a second here, but I wanted to find the gold standard, and this is something that went away 90 years ago.The n the gold standard is a monetary system where dollars can be swapped for a fixed amount of gold. And here's that chart. Way back in the day, ...

Thanks for having me on, Frank. Yeah, dollar's being held back by some uncertainty here and frankly being down 8%. It's just a scratch. Susan, it's just you're calling it just a scratch like Elon Musk.So, it's actually down more than 9%. But I want to get to the action this week in particular. So, I think a lot of people are saying people are piling into the dollar as a safe haven, but you're saying it's something a bit different.You're saying it's some short covering and just also a bare market bounce. Yea ...

Group 1 - Federal regulators issued an urgent warning regarding the risk of Boeing 737 MAX engines malfunctioning, which could allow smoke to enter the airplane cabin or cockpit, posing a significant danger to pilots [1] - The warning was prompted by two incidents involving Southwest Airlines flights where CFM International LEAP-1B engines malfunctioned after bird strikes, resulting in smoke entering the cabins [2] - The NTSB reported that in December 2023, a Boeing 737-8 experienced "acrid white smoke" shortly after takeoff, severely impairing the captain's visibility, and another incident in March 2023 also involved smoke entering the passenger cabin [3] Group 2 - The NTSB recommended modifications to the engines used on Boeing 737 MAX planes and Airbus A32 jets, urging the FAA to assess whether LEAP-1A and LEAP-1C engines could face similar issues [4] - The NTSB expressed concerns that flight crews may be unaware of the smoke hazard and lack knowledge on how to respond, urging the FAA to require operators like Boeing to inform crews about the risks [4] - Boeing has revised its flight manuals to guide pilots on preventing smoke from entering the cockpit or cabin, and is collaborating with CFM International on a software design update in response to the NTSB's recommendations [6]

Key Takeaways PAAS Q1 revenues rose 28.6% to $773M, with EPS jumping to $0.42 from $0.01 on higher prices and lower costs. AG's Q1 revenues surged 130% to $243.9M, driven by Cerro Los Gatos output and higher silver prices. Earnings estimates for PAAS in 2025 rose to $1.47, while AG's 2025 and 2026 estimates have both declined.Pan American Silver (PAAS) and First Majestic Silver (AG) are well-known names in the silver mining sector, sharing several key similarities that define their strategic positioning a ...
