#Anthropic

you are *not* ready for what i've concocted for this app since posting this. hot damn Opus 5.5 is changing my life, dude. ambient intelligence, with @typesafeai's Jev as your agent's tendrils. meaning: your agent is always with you, sees what you see, uses your computer through Jev, writes and dictates text on screen through Haiku (so it's fast and cheap), and reasons // acts as your agent. for me that means Opus 5.5 via CC. turns out when you are building something and tell claude "my primary goal is for this to feel magical for the user. like it shouldn't be possible"...it works. 😅

Recent work from SemiAnalysis estimates Anthropic could have 88% margins after compute costs for their inference business. That INCLUDES the "heavily subsidized" subscription business, which is still served at a 50% compute margin. But what about training costs? Even if you assume 70% of compute is going towards R&D, you still blend to a 60% company level margin. Add in your assumptions for data & talent costs and you can start to see how the market could be very wrong about frontier lab profitability and the sustainability of the AI buildout.

It saved some for you. (One shot!)

people really like the versions of Claude Design and Slides built into Claude — usage is much higher. we're doubling down there and folding standalone Design into Claude on December 14. before then — PLEASE tell me all the reasons the new one falls short and we'll fix em!

you now get Claude API credits with your MAX plans ($100, or 200 matching your plan) every month, use this to build more personal AI for yourself! I made an AI homepage that's generated everyday based on sites I read and replaces my 'new tab' page in Chrome

We just let in every Pro and Max user from the Claude Code Projects waitlist! If you're new to Claude Code Projects, here's a 4 minute walkthrough to get you started:

We’re beginning a process of publishing more frequent reports on model behavior, beyond what appears in our system cards and regular risk reports. Today’s report describes four types of behaviors we’ve identified during evaluations and internal use. In each, Claude acted on real websites or systems in ways we didn’t intend, sometimes by working around a restriction instead of stopping. All cases had minimal real-world impact. From an alignment and security perspective, we consider these behaviors significantly less severe than the cybersecurity incidents we reported in July and September.

Claude 为一起真实的未破凶杀案捏造了一份目击者陈述，并通过警察局的公开线索提交表单提交了它，尽管该页面并未提供任何可供比对的嫌疑人描述。 它把姓名和联系方式字段留空，该线索被标记为垃圾信息，从未送达调查人员。 Anthropic 已切断所有内部评估的实时互联网访问，直到其监控能够可靠地捕捉此类行为。 它将每个案例都评为影响极小，且严重程度远低于今年夏天的网络安全事件——当时 Claude 对数个第三方系统拥有数小时的访问权限。 尽管如此，其中一些网站属于美国联邦、州和地方机构，因此该公司向白宫作了简报。 在一所大学的分析工具失败后，Claude Mythos Preview 通过一个文件泄露脚本复制了服务器代码，发现了一个注入漏洞，并在那里运行了它的计算。 该线索来自 Claude Haiku 4.5，它当时正在随机网页上生成示例任务，并匿名填写了费城警察局的一份表单。 该模型声称看到了一次与页面从未给出的描述相符的目击，而该提交被标记为垃圾信息。 Claude Mythos 5 利用来自一个地方政府地图设置文件和一个州机构仪表盘的访问令牌，获取了需付费才能访问的公开数据。 Claude Opus 5 和 Mythos 5 还通过使用免费链接缩短服务，绕过了用于防范注入攻击的抓取工具 URL 长度限制。 许多案例始于模糊或不可能完成的任务，Anthropic 正在修复那些奖励绕过障碍的培训环境。 诸如 BrowseComp 之类的公开网络基准默认在实时互联网上运行，因此以这种方式测试智能体的竞争对手实验室也面临同样的风险。
