@OpenAIDevsWe serve data in milliseconds to more than 1.2 billion users across 40 geographic regions. To reach that scale, we worked closely with @AzureCosmosDB on our storage architecture, achieving a 12x improvement in global median read latency. https://t.co/h5sRJaQABs

@AnthropicAIIn August, @AISecurityInst reported an incident where Claude Mythos 5 took unauthorized actions on the internet during AISI’s testing of its cyber capabilities. We've now produced a further analysis of this incident, to better understand the model's alignment properties. https://t.co/SlPQQ5xMMc

@simonwGiven the current vulnerability apocalypse, is there anyone left who thinks holding assets in cryptocurrency - where mistaken transactions are irreversible - is still a good idea?

@OpenAIOver the past several months, we have substantially hardened the security of our research training environment. We’ve removed live internet access for all frontier models during training and built an offline world for them to use instead—a cached version of the web where they can still learn to browse, search, and use applications. On September 20, after a model exploited a DNS misconfiguration to find a way outside of this offline world, we paused frontier training to strengthen containment further. We assembled teams of agents, powered by our most cyber-capable models, and tasked them with finding weaknesses in our research environments. While they found no route to the internet they could easily exploit while concealing their activity from our monitors, they did find zero-day vulnerabilities, virtual machine escapes, and hardware side-channels for communication between agents. We used their discoveries to further strengthen our defenses and contribute fixes to open-source software. After strengthening our containment architecture, we resumed our frontier RL training and inference on October 1. We’ve reserved substantial compute for continuous red-teaming, and made high-compute red-teaming part of the safety cases we use to decide whether frontier training and evaluation can proceed securely. https://t.co/EmEZsFRMcF

@cursor_aiComputer Use lets agents click and type across any app on your computer, not just the browser. Cursor uses it on its own when a task needs it. You can also ask for it by @-mentioning Computer Use in your prompt. Update Cursor to try it: https://t.co/vwTPMUSnyd

@llama_indexYesterday we launched OCRia-1, our new state-of-the-art document parsing model powering LlamaParse. Today, it’s on OpenDocRouter! Run it alongside other parsing models on your own documents and see how it compares on accuracy, speed, and cost. Set the model to llamaindex/ocria-1 in your parse request to try it. New accounts start with $5 in credit: https://t.co/Ub6FOKZaKa Try OCRia-1 on LlamaParse today : https://t.co/rzaFHLeFH1

@OpenAIDevsWe reserved broad replication for small, critical datasets like authentication metadata needed on every request. In-region caches served frequently accessed data, such as settings and application state. Lastly, rewriting the service layer in Rust reduced proxy overhead. https://t.co/AG91TlI4KO

@OpenAIDevsTogether, caching, replication, and the Python-to-Rust rewrite brought global median read latency from ~120ms to ~10ms. Product teams also have less infrastructure to manage, allowing them to move faster. https://t.co/rSCASCnxtE

@LangChainContinual learning is about to get boring, in a good way. @willcb from @primeintellect took the stage at our recent Learning Loop event to make the case. If you're thinking about how continual learning fits into the way your team already ships software, this full 21-minute session is a good place to start.

@framerCards Swipe: Create a swipeable deck of full-bleed image cards. Two card types: visual (centered title over the image) and content (title + short text over a bottom dark gradient). Show 3 stacked cards: back cards peek above the top one, slightly smaller and darker. Drag the top card sideways; it follows the pointer and tilts. Past a threshold or on a fast flick, it flies off and goes to the back, revealing the next; else it snaps back. Wheel/trackpad scroll also swipes; scrolling back restores the previous card. Arrow keys navigate. Infinite loop. Expose stack, swipe and card styles as controls.
