Computer use agents automate digital tasks by directly interacting with graphical user interfaces (GUIs) on computers and mobile devices, offering significant potential to enhance human productivity by completing an open-ended space of user queries. However, current agents face significant challenges: imprecise grounding of GUI elements, difficulties with long-horizon task planning, and performance bottlenecks from relying on single generalist models for diverse cognitive tasks. To this end, we introduce Agent S2, a novel compositional framework that delegates cognitive responsibilities across various generalist and specialist models. We propose a novel Mixture-of-Grounding technique to achieve precise GUI localization and introduce Proactive Hierarchical Planning, dynamically refining action plans at multiple temporal scales in response to evolving observations. Evaluations demonstrate that Agent S2 establishes new state-of-the-art (SOTA) performance on three prominent computer use benchmarks. Specifically, Agent S2 achieves 18.9% and 32.7% relative improvements over leading baseline agents such as Claude Computer Use and UI-TARS on the OSWorld 15-step and 50-step evaluation. Moreover, Agent S2 generalizes effectively to other operating systems and applications, surpassing previous best methods by 52.8% on WindowsAgentArena and by 16.52% on AndroidWorld relatively.

The other top robot vacuum brands can release as many models as they want, but the "Shark vs. Roomba" debate isn't leaving the Google search bar anytime soon. There's always an even bigger spotlight on the feud when comparing their deals during various sale events, and the last day of Amazon's Big Spring Sale is seeing a big showdown between Shark and iRobot's two most expensive robot vacuum and mop combos: The Shark PowerDetect NeverTouch Pro and iRobot Roomba Combo Max AutoWash Dock are both down from their over- 1,000 prices to 799.99 ( 799 for the Roomba, so you'd technically be saving almost a dollar extra). Both can wash and dry their own mopping pads whereas the models right below each in the family tree, the Roomba Combo j9 and Shark PowerDetect NeverTouch (no Pro) only refill their water tanks, but need you to throw the pads in the washing machine. The self-washing situation is definitely worth the upgrade in my eyes. I've tested both of them, and have some intel as to who should pick the Shark and who should pick the Roomba.

Vidya Nayak, Director of Product Design at Yahoo Search, is aware it's not easy to be a visible female tech executive. She also knows talking about her experiences as a woman in the industry makes a difference. "Sharing my own stories honestly and authentically encourages other women in the room to come forward and share theirs," Nayak tells Mashable. "This creates a sense of community and solidarity where women feel seen, heard, and empowered to navigate their day-to-day boldly." Nayak has a big job at Yahoo, which ranks as the U.S.'s second most-visited website.

Amazon's Big Spring Sale has brought us the first discount on a major CES 2025 robot vacuum. Coincidentally, the Eufy E20 is not only one of the best robot vacuum deals from the sale but also one of the best stick vacuum deals. Yep, you read that right: It's a 3-in-1 robot vacuum that can transform into a cordless stick vacuum (as well as a handheld).

OpenAI has been doubling its audience for ChatGPT at a rapid rate, and the addition of its latest image generation feature has increased the AI assistant's popularity. Today, CEO Sam Altman posted to X that the service "added one million users in the last hour," calling it a "biblical demand" for the image generation. When the company announced the rollout of image generation in ChatGPT last week, the tool was meant to be available to all user tiers. However, the high degree of interest meant that access for free users was walked back. Now, the company is reporting "issues with new signups," which has been its status for more than a day.

Sam Altman today revealed that OpenAI will release an open weight artificial intelligence model in the coming months. "We are excited to release a powerful new open-weight language model with reasoning in the coming months," Altman wrote on X. Altman said in the post that the company has been thinking about releasing an open weight model for some time, adding "now it feels important to do." The move is partly a response to the runaway success of the R1 model from Chinese company DeepSeek, as well as the popularity of Meta's Llama models. OpenAI may also feel the need to show that it can train the new model more cheaply, since DeepSeek's model was purportedly trained at a fraction of the cost of most large AI models. "This is amazing news," Clement Delangue, cofounder and CEO of HuggingFace, a company that specializes in hosting open AI models, told WIRED.

LibreOffice, the open-source alternative to Microsoft Office, is seeing a serious uptick in downloads (as first reported by Computerworld) with February's release of version 25.2. According to the Document Foundation, LibreOffice, which runs on Linux, MacOS, and Windows, now boasts around 200 million worldwide users. Document Foundation's Mike Saunders said that the exact number of total users is difficult to pinpoint, as the Foundation does not track users in order to maintain their privacy. Sanders also noted that downloads of LibreOffice have been climbing with every new release, which is a good indicator that The Document Foundation is doing something right. Why is LibreOffice seeing an uptick in downloads now?

If there's one thing you can count on with AI tools is that they'll launch without most of the promised features. It happened with Apple Intelligence. It happened with Galaxy AI. Now, it's happening with Alexa, Amazon's AI-heavy upgrade to its virtual assistant. The tool is officially available but it doesn't do a whole lot, according to reporting by The Washington Post.

Don't buy this multi-outlet for its surge protection feature, as it won't warn you when it can no longer deliver it. TP-Link's Tapo Smart Wi-Fi Wall Outlet Extender has some great features, as well as one critical shortcoming that prevents us from recommending it. Tapo doesn't make big promises for this product in terms of its surge protection, but it does list a key feature on the box: the ability to warn you when it can no longer provide surge protection. The Tapo Smart Wi-Fi Wall Outlet Extender isn't all bad news--provided you're not buying it for surge protection. Most surge protectors use sacrificial MOVs (metal oxide varistors) to absorb excess voltage from power surges, and this one is no exception.

In a world and industry which is becoming more commercialised, over sanitised, robotic, structured and predictable, Tyler's greatest strength is the opposite to all of that." That's quite the sell for Southampton's 19-year-old midfield star Tyler Dibling, especially given his basic Premier League career numbers amount to 25 appearances, 1540 minutes played, two goals and zero assists. But that gushing description from one senior source at the club, speaking to BBC Sport anonymously, hints at an emerging talent interesting a host of top clubs and why there are some unsubstantiated reports of a 100m price tag on his head. With the Saints facing an immediate relegation back to the Championship, Dibling's future is likely to be one of the summer's more interesting sagas, with Manchester United, Arsenal, Tottenham and Bayern Munich all reportedly chasing his signature. Another source close to the club suggested Southampton turned down previously unreported bids of 35m from Tottenham and 30m from RB Leipzig in January, with the club valuing Dibling at 55m at the start of the winter window. Southampton have not commented on those rumours, but what is known is that Dibling is one of the lowest paid players in Southampton's squad and has a deal that expires in 2027, after Southampton triggered a 12-month extension option. He signed his last contract in December 2023, when he had played just five minutes of senior football. The England Under-21 international has so far resisted the club's offers of a new deal in what has been a breakthrough season for him, despite a wretched campaign which could still see Southampton relegated with the Premier League's lowest ever points total. His dribbles completed per game (2.34) and fouls won per game (2.57) place him in the top 10. "He's the most fearless player I've ever worked with," former Saints Under-21 head coach Adam Asghar tells BBC Sport. "He's totally unique to anything I've seen before.
