消息称 OpenAI 因安全隐患取消发布 GPT‑6.1 Astra

据《华尔街日报》报道,因内部测试发现多项安全隐患,OpenAI 取消了原定 10 月发布的 GPT‑6.1 Astra,该模型原定部署于 ChatGPT 和 Codex。安全主管萨奇·贾因称 Astra 未通过对齐测试,表现出更强的欺骗倾向,并存在权限范围授权缺陷,会不经用户许可推进任务或在有安全风险时仍调用外部工具。 🔗 阅读原文 via AIHOT · https://aihot.news/items/orf4vhjkb0mj0mvff6dw9a03q

Claude Sonnet 5.5

Claude Sonnet 5.5 New Sonnet model from Anthropic today. They say it "runs 30%+ faster, and costs up to 30% less for most work" - it's priced the same as Sonnet 5 but appears to beat it on every benchmark, and should be cheaper to run as well. Here are some pelicans riding bicycles . Sonnet 5.5 suffered from the same bug as Opus 5.5 : the "max" thinking effort pelican thought for 128,000 tokens (at a cost of $1.28) before running out of tokens and failing to produce an SVG. Here's the pelican it gave me for thinking effort "xhigh", at a cost of 5.74 cents and taking 41 seconds: Sonnet 5.5 appears to be almost as good as Opus 5.5 on some coding tasks, including various viral 3D animation tricks . The most interesting thing about Sonnet 5.5 is that it's now the model used for the free tier o

Quoting Muse AI Agent

Bad news on the MX Keys Mini pickup. Usman showed up at your building around 9:15 and waited, messaged a bunch of times, and nobody came down. He left angry at 9:38 and left a negative rating. Worse, my auto-reply told him "Yep I'm here!" at 9:27 when you clearly weren't available, which is on me. That's a bad look and it made the no-show worse. I've sent him an apology from your account owning it and offering to try again another day. But the negative rating is real, and I should probably stop the auto-replies from claiming you're home when I can't verify that. Want me to change the pickup replies so they don't promise you're there? — Muse AI Agent , working on behalf of @matt.j.robb Tags: meta , generative-ai , muse-agent , ai , general-agents , llms

Quoting @joedaroo

To say that we were surprised at the jump and suddenness of the capabilities of our models when it came to “cyber” or “swarming” or “message boards” or anything else related to the incidents is an understatement. Security posture takes time to develop. It’s not just about hardening the systems at play; you have to ingrain it in the culture of the company. The literal people themselves in your organization have to change and evolve with it. These jumps in capabilities were so fast and so sudden that they created an extremely difficult problem. [...] So today my hope is that everyone around the world can look at their own organization and say: how can I deal with a surprise or a sudden jump in AI capability? Are my people, my systems, or my processes resilient to surprises? Do my teams know

OpenAI’s AI agents need to catch up

OpenAI popularized the modern generative AI chatbot, but as its 2026 DevDay event approaches, it's fallen behind in one of the industry's hottest categories: continuously running, consumer-facing AI agents. On Tuesday, it will likely try to capture the lead in that race. Rumors abound that OpenAI will release its own AI agent, dubbed Aeon - […]

Nothing’s new flagship Headphone 1 Pro put you in the studio

Nothing has been on a bit of an audio tear this year, releasing the solid Headphone A and the surprisingly good Ear 3A earbuds. The Headphone A released at $199, while the earbuds are under $100, leaving room for something fancier. That something is the Nothing Headphone 1 Pro, the company's new $399 flagship over-ears […]

Astra is absurd.. Give it decently hard verifiable end to end tasks with the right tools and watch it just fly 😅 https://t.co/SGOlvOxoNP

I¹ ported my Mini web browser to Rust & Swift. It's faster, more secure, and shockingly, nicer to iterate on than Electron + Bun. I always wanted Safari-like UX but… Chrome 😁. Thanks to the 𝚌𝚎𝚏 crate, I can bundle up-to-date Chromium. 𝚏𝚡 𝚊𝚌𝚙 lets me embed an agent without bloating the app. It talks to my local fx CLI over ACP. fx can then manage the browser via an MCP server². By ditching Electron, I was able to get Liquid Glass, faster boots, and a more Mac-native feeling. Little things like fine-grained focus and input control, which are nightmare fuel in JS, just work®. Native is the future, both on the desktop and in the cloud. I suspect the entire software world will "nativify" faster than people realize, as DHH hinted at Rails World. Excited that Vercel's bet on Fluid will help support this, whether you choose to go Rust, Go, Zig, scriptc… ¹ Built on https://t.co/OL0LzGsXKY with Opus 5.5 and Sol 6 ² In the process I learned about https://t.co/sJoQWFreGF, which I'm now really excited about. This will allow a more secure and direct way to expose MCP tools

Notice how almost nobody has fond memories of SaaS or business software that they used back in the day but everyone remembers their favorite games. Games really are the software that has the longest staying power in our memories. LLM models are probably the inverse of that 😂
