However, such methods are usually sensitive to environmental dynamics-irrelevant information, e.g., white-noise. To handle such dynamics-irrelevant information, we propose a Dynamic Bottleneck (DB) model, which attains a dynamics-relevant representation based on the information-bottleneck principle.

That is, we simultaneously both solve for the DEQ fixed point and optimize over network inputs, all within a single "augmented" DEQ model that jointly encodes both the original network and the optimization

We then demonstrate the utility of this framework in two respects.

Mozilla is building'AI windows' in Firefox and giving full control to you Mozilla is taking its time to get AI right, while its rivals rush towards the (continually moving) finish line. In February, Mozilla Firefox revealed that the company was adding third-party AI to its browser. This week, the company further revealed that it's doing so via "AI windows" for ChatGPT and other services. Back in its original announcement, Mozilla said it was actually deploying third-party AI services to a small portion of its user base.

Back in mid-October, some data miners found code in one of the beta versions of ChatGPT that indicated it would soon be possible to have "group chats" in the app. Now, OpenAI has confirmed that ChatGPT will support group chats with up to 20 participants. OpenAI sees group chats as an opportunity for families, groups of friends, and/or coworkers to use ChatGPT when making holiday plans, booking restaurant outings, or planning new projects.

How AI is writing phishing emails that look real Cyber criminals are using AI tools to attack their victims faster and more effectively. Users must now be even more vigilant. Back in February 2025, several media outlets warned of a new threat targeting users of Google's Gmail email service. Attackers used AI technology to perfect phishing emails and make them look more convincing.

Plus: Anthropic's AI was coopted by Chinese hackers ChatGPT maker OpenAI has built an experimental large language model that is far easier to understand than typical models. It's a big deal, because today's LLMs are black boxes: Nobody fully understands how they do what they do. Building a model that is more transparent sheds light on how LLMs work in general, helping researchers figure out why models hallucinate, why they go off the rails, and just how far we should trust them with critical tasks. Google DeepMind has built a new video-game-playing agent called SIMA 2 that can navigate and solve problems in 3D virtual worlds. The company claims it's a big step toward more general-purpose agents and better real-world robots. The company first demoed SIMA (which stands for "scalable instructable multiworld agent") last year.

We propose re-drawing the random subspace at each step, which yields significantly better performance.

Windows Recall is one of the biggest AI features Microsoft has added to Windows 11. It's useful, but it comes with some privacy trade-offs. If you're a Windows 11 user, and specifically an owner of a Microsoft Copilot+ PC that has the necessary AI processing power, you can now take advantage of Windows Recall. It works like a memory for your computer, using screenshots to keep track of everything you're doing on Windows, and then letting you search back through it. The idea is to give you something like your web browsing history, but for the whole computer.

You Won't Be Able to Offload Your Holiday Shopping to AI Agents Anytime Soon Chatbot developers and retail giants are battling over user data as they lay the foundation for a future in which AI agents can do all your online shopping for you. Ask OpenAI's ChatGPT about a product on Etsy, and chances are you can enter your payment details and buy it without ever leaving the app. Instant Checkout was one of the first features to emerge from a recent wave of partnerships between leading AI and ecommerce companies. The aim is to encourage people to hand off parts of the browsing and ordering experience to AI tools and usher in an era of agentic shopping. But while these so-called agents have started to become more commonplace, they are far from taking over as full-time virtual buyers. OpenAI, Google, Amazon, and other AI chatbot developers are still negotiating with major retail partners on the best way to limit costly mistakes by agents and the amount of product data and chat history that have to be exchanged to make these agents successful, according to executives at seven tech and ecommerce companies who spoke with WIRED.
