While neural conversation models have shown great potentials towards generating informative and engaging responses via introducing external knowledge, learning such a model often requires knowledge-grounded dialogues that are difficult to obtain. To overcome the data challenge and reduce the cost of building a knowledgegrounded dialogue system, we explore the problem under a zero-resource setting by assuming no context-knowledge-response triples are needed for training. To this end, we propose representing the knowledge that bridges a context and a response and the way that the knowledge is expressed as latent variables, and devise a variational approach that can effectively estimate a generation model from a dialogue corpus and a knowledge corpus that are independent with each other. Evaluation results on three benchmarks of knowledge-grounded dialogue generation indicate that our model can achieve comparable performance with stateof-the-art methods that rely on knowledge-grounded dialogues for training, and exhibits a good generalization ability over different topics and different datasets.

Imagine an AI bot that can fill out online forms, book airline flights, order groceries, and more. That's the intent of OpenAI's new Operator, an AI that acts as an independent agent to carry out your commands all on its own. Released as a research preview on Thursday, Operator is able to interact directly with a web browser. That means it can navigate web pages by typing, scrolling, and clicking in all the right spots, just as you would yourself. The difference here is that Operator aims to do all that without any intervention on your part.

This week, OpenAI is introducing a research preview called Operator. I initially wanted to do a hands-on, but once I found out that you need a Pro account (which costs 200 per month), I decided to watch the various OpenAI demos, share them with you, and then share my thoughts. Altman did say that users of the 20-per-month Plus plan would eventually be able to use Operator. Operator is an AI agent. Fundamentally, it simulates keyboard and mouse clicks in a browser, reading the screen, and performing actions. Also: Have a genealogy mystery?

Theorem proving in natural mathematical language - the mixture of symbolic and natural language used by humans - plays a central role in mathematical advances and education, and tests aspects of reasoning that are core to intelligence. Yet it has remained underexplored with modern generative models. We study largescale language models on two new generation tasks: suggesting the next step in a mathematical proof, and full proof generation.

"The Agency" star Katherine Waterston admitted she finds AI generally "terrifying" for Hollywood and beyond. Screenwriter Paul Schrader, known for his critically acclaimed works like "Taxi Driver," "Raging Bull" and "First Reformed," surprised fans when he shared his apparent approval of artificial intelligence. In a series of posts last week, the Oscar-nominee marveled at AI and ChatGPT's capabilities when it came to his profession. "I've just come to realize AI is smarter than I am. Has better ideas, has more efficient ways to execute them," he wrote on Jan 16. "Taxi Driver" screenwriter and director Paul Schrader surprised fans with his interest in artificial intelligence.

Given the recent impressive accomplishments of language models (LMs) for code generation, we explore the use of LMs as general adaptive mutation and crossover operators for an evolutionary neural architecture search (NAS) algorithm.

Operator, OpenAI's agent that can perform multi-step tasks autonomously, has arrived. The ChatGPT maker introduced a preview mode of Operator on Thursday, detailing how it works and what it's capable of. Operator can browse the web, performing tasks like calculating refunds from a canceled order and finding customers with specific criteria in an internal sales database. It can also buy groceries and send emails. On a computer, Operator can perform various tasks, like downloading files, combining PDFs, analyzing spreadsheets, and exporting images.

This week US President Donald Trump announced a joint venture between OpenAI, Japanese conglomerate SoftBank Group, and Abu Dhabi's AI-focused sovereign wealth fund MGX, to put as much as 500 billion over multiple years into US data centers dedicated to artificial intelligence. Trump appeared at the White House with OpenAI CEO Sam Altman, SoftBank chairman Masayoshi Son, and Oracle founder Larry Ellison. Oracle is one of the technology partners for the joint initiative -- dubbed Stargate -- along with Microsoft, ARM Holdings, and Nvidia.

According to one Wall Street analyst, Jackson Ader of the KeyBanc Capital Markets brokerage, "Capital spending for the major hyperscalers" -- that is, Amazon, Alphabet, Microsoft, Oracle, Meta, and Alibaba -- "will be 286.5 billion in 2025, and 308.8 billion in 2026, after making some adjustments to consensus estimates."

OpenAI has begun previewing a new tool called Operator that can navigate within a web browser. According to a blog post published Thursday, the software is powered by what the company calls a Computer-Using Agent. "CUA is trained to interact with graphical user interfaces (GUIs) -- the buttons, menus, and text fields people see on a screen -- just as humans do," says OpenAI of the model. "This gives it the flexibility to perform digital tasks without using OS- or web-specific APIs." The current release of Operator builds on OpenAI's GPT-4o model.

This week, OpenAI and other tech companies joined US president Donald Trump at the White House to pledge a private investment of half a trillion dollars in US data centres over the next four years. The "Stargate Project" could power an ambitious expansion of AI technology – with repercussions for the US electricity grid and the country's energy future. The Stargate announcement comes as North America has been experiencing surging electricity demand in recent years.
