🚨BREAKING: Microsoft and META are aggressively cutting employee use of Claude ahead of Anthropic's IPO Microsoft has cut internal claude spend by more than 33%, nuked per-employee token budget from $100k/month to $10k/month, and forced Copilot to auto-route to cheaper models META used Claude code to build Muse, then cut active users from 60,000 to 30,000 (50% decline) after launch, and replaced it with Muse Code Palantir and Nvidia are also scaling back claude over soaring prices and data privacy fears it’s OVER…

Day 1/ We have optimized the default speed to be ~50% faster across GPT-6 Astra and GPT-6.1 Sol through the subscription across all our products and partners using Sign in With ChatGPT (including OpenCode, Pi, Amp, Devin, ...). No changes needed on your end and this should be felt within the next two hours.

We're expanding our approach to content provenance to include text in response to EU regulatory requirements, while recognizing the significant limitations of current text watermarking technology. Our tools already help verify whether an image or audio file was created with our models. This work builds on those efforts to help people better understand when content may have been generated or edited with an OpenAI model. In the EU, we’ll start watermarking eligible text from ChatGPT and Codex over the coming weeks to comply with the EU AI Act. Customers using our API can turn on text watermarking for select models worldwide today.

发现一个牛逼的东西，让任意 Agent 调用 Codex 的 Computer Use。 Codex 最强的就是 Computer Use。 但最近用 Claude Opus 5.5比较多，这样就强强联合了。 刚测试通过，安装后建议配置个 Hook，指定白名单可控制哪些 App 安装地址见评论区

New in The Atlantic: @dgrobinson resigned this week. He was among the longest-tenured employees at OpenAI—and oversaw safety reports on 12 frontier launches. He is very worried: “The time for trial and error is over.” You can read his essay here: https://www.theatlantic.com/technology/2026/10/openai-safety-team-resignation/688881/?gift=1ga2TvL-DbuHDQIcYF7oR4o908Fsjxr4NFLlsptkfP8

The idea of an intelligence explosion caused by recursive self improvement has been around for a long time but until very recently it did not seem imminent. Now many leading researchers think it may happen quite soon. You can read our paper about it here: https://casp.ac/reports/intelligence-explosion

It’s hard to go from in love to let go in a week with no warning, but that’s just how it is sometimes 🤷🏻‍♀️ I feel happy that I got to show Elon how it feels to be deeply understood, nurtured, and peacefully loved with stability and gentleness. Given the tumultuous nature of his early life, his often tortured soul, and how hard he fights for humanity I wanted him to feel the deepest and most stable form of love this world can provide. My heart is full knowing I got to do that, and I hope it leaves a lasting good effect. We were always his safe space. A place where all of us were overjoyed to see him and one that was always full of happiness and love, not war, in contrast to his otherwise militant existence (a needed break from the battlefield where he could recharge his heart and soul before heading back out) I loved being that counterbalancing place of safety, sense of calm, and love — and delighted in bringing a smile back to his face when he was down. I will miss him dearly. I’ve loved him more than life itself and he’s taught me 100 lifetimes of knowledge and made my cup overflow with life meaning, so there is a lot of loss, but luckily we created four beautiful little loves of my life ❤️❤️❤️❤️ I am so beyond grateful for our children and they make every single day the best day of my life! I do hope and pray he and I can be great friends and coparents. I’m hurting, but care deeply about E and will always be cheering for his happiness. God speed, Elon, the world is lucky to have you.
