Reddit Inc. forged a partnership with OpenAI that will bring its content to the chatbot ChatGPT and other products, while also helping the social media company add new artificial intelligence features to its forums. Shares of Reddit, which had their initial public offering in March, jumped as much as 15% in late trading following the announcement. The agreement "will enable OpenAI's AI tools to better understand and showcase Reddit content, especially on recent topics," the companies said Thursday in a joint statement. The deal allows OpenAI to display Reddit's content and train AI systems on its partner's data. Reddit will also offer its users new AI-based tools built on models created by OpenAI, which will place ads on its partner's site.

At the end of I/O, Google's annual developer conference at the Shoreline Amphitheater in Mountain View, Google CEO Sundar Pichai revealed that the company had said "AI" 121 times. That, essentially, was the crux of Google's two-hour keynote -- stuffing AI into every Google app and service used by more than two billion people around the world. Here are all the major updates from Google's big event, along with some additional announcements that came after the keynote. Google announced a brand new AI model called Gemini 1.5 Flash, which it says is optimised for speed and efficiency. Flash sits between Gemini 1.5 Pro and Gemini 1.5 Nano, which its the company's smallest model that runs locally on device.

TikTok is ramping up its efforts to automatically label AI-generated content in its app, even when it was created with third-party tools. The company announced plans to support content credentials, a kind of digital watermark that indicates the use of generative AI. TikTok's rules already require creators to disclose "realistic" AI-generated content. But that policy can be difficult for the company to enforce, particularly when creators use other companies' AI tools. But because content credentials are increasingly used across the AI industry, TikTok's new automated labels should be able to address some of those gaps. Often described as a "nutrition label for digital content," content credentials attach "tamper-evident metadata" that can trace the origins of an image and AI tools that were used to edit it along the way.

Elon Musk's Neuralink has shared a progress update about the first person to receive a brain chip that allows him to operate a computer and play video games with his mind. The company announced that it has been more than 100 days since Noland Arbaugh had the device implanted in his brain - and the 29-year-old is still doing. Arbaugh suffered a life-changing driving accident whilst working as a camp counselor in 2016, which left him with'absolutely no feeling' from the shoulders down. His life changed again on January 27 when he underwent a 30-minute procedure that used a'sewing machine-like' robot to remove a small chunk of his skull and stitch the chip into his brain. However, Neuralink revealed that some of the threads connected to the chip had retracted weeks after the surgery, resulting in a decrease in the number of effective nodes - but modified the algorithm to boost signal translations.

Profits at Microsoft beat Wall Street's expectations as its heavy bet on artificial intelligence continued to bear fruit in the second quarter. The technology giant has invested billions of dollars into AI in a bid to turbocharge its growth, particularly of its cloud computing services. Its cloud computing revenue surged by more than 20% in the latest quarter. Microsoft's AI tools "are orchestrating a new era of AI transformation, driving better business outcomes across every role and industry," said Satya Nadella, the chief executive of Microsoft. As the group races to integrate AI across its software and services, Nadella said its Azure cloud computing business saw the pace of deals worth 100m and 10m increase by double-digit percentages.

Nearly a year after adding generative AI-powered editing capabilities to Photoshop, Adobe is souping up its flagship product with even more AI. On Tuesday, the company announced that Photoshop is getting the ability to generate images with simple text prompts directly within the app. There are also new features to let the AI draw inspiration from reference images to create new ones and generate backgrounds more easily. The tools will make using Photoshop easier for both professionals as well as casual enthusiasts who may have found the app's learning curve to be steep, Adobe thinks. "A big, blank canvas can sometimes be the biggest barrier," Erin Boyce, Photoshop's senior marketing director, told Engadget in an interview. "This really speeds up time to creation.

AMD today launched its most recent generation of business processors for business PCs, the Ryzen Pro 8000 series, for both desktop and laptops. For now, AMD will be the only CPU vendor offering AI-powered NPUs in business desktop PCs. AMD's launch arrives on the heels of Intel's 14th-gen vPro platform, which also offers desktop and mobile parts. The difference is that Intel launched its vPro refresh based upon the "Raptor Lake Refresh" architecture, which lacks AI; AMD's Ryzen Pro 8000 series is relatively consistent across both its mobile and desktop offerings. However, not every new Ryzen Pro 8000 mobile or desktop chip includes AI support.

China's Baidu has announced that "Ernie Bot", its rival to ChatGPT, has racked up more than 200 million users, roughly double as many as in December. Baidu CEO Robin Li also said Ernie Bot's application programming interface (API) is being used 200 million times every day, meaning the chatbot was requested by its user to conduct tasks that many times a day. The number of enterprise clients for the chatbot reached 85,000, Li said at a conference in Shenzhen on Tuesday. In February, he told analysts that Baidu was starting to generate revenue from Ernie and in the fourth quarter, the company had earned several hundred million yuan using AI to improve its advertising services and help other companies build their own models. Last March, Ernie Bot was the first locally developed ChatGPT-like chatbot to be announced in China but it only won approval for public release in August, becoming one of the first eight AI chatbots Beijing authorised.

Media streaming is the dominant application over wireless edge (access) networks. The increasing softwarization of such networks has led to efforts at intelligent control, wherein application-specific actions may be dynamically taken to enhance the user experience. The goal of this work is to develop and demonstrate learning-based policies for optimal decision making to determine which clients to dynamically prioritize in a video streaming setting. We formulate the policy design question as a constrained Markov decision problem (CMDP), and observe that by using a Lagrangian relaxation we can decompose it into single-client problems. Further, the optimal policy takes a threshold form in the video buffer length, which enables us to design an efficient constrained reinforcement learning (CRL) algorithm to learn it. Specifically, we show that a natural policy gradient (NPG) based algorithm that is derived using the structure of our problem converges to the globally optimal policy. We then develop a simulation environment for training, and a real-world intelligent controller attached to a WiFi access point for evaluation. We empirically show that the structured learning approach enables fast learning. Furthermore, such a structured policy can be easily deployed due to low computational complexity, leading to policy execution taking only about 15$\mu$s. Using YouTube streaming experiments in a resource constrained scenario, we demonstrate that the CRL approach can increase quality of experience (QOE) by over 30\%.

Picture the scene: Your date has gone well and you and your partner might sleep together. Like any safe adult, you assume there will be a conversation about STI status and the use of protection. Now imagine how you would feel if they asked to take a photo of your penis and upload it to a website you've never heard of. That's the future of intimacy, as imagined by Calmara, a new service launched by "men's health" startup HeHealth. Its press release suggests users take a picture of their partner's penis so it can be run through a deep learning model for visual signs of sexually-transmitted infections. And while the website suggests users should wear protection, a banner atop the HeHealth sites describes the app as "Your intimate bestie for unprotected sex."
