Meta didn't wait for Tuesday's LlamaCon keynote to unveil its first big AI announcement of the week. The company launched a standalone app that competes with ChatGPT, Gemini, Claude and other multimodal AI chatbots. Sticking to the company's roots, the app also includes a social feed and the ability to draw on info from your profile and posts you've shared. The Meta AI app offers similar features to rival chatbots, including text and voice chats, live web access and the ability to generate and edit images. But it also includes a Discover feed that (for better or worse) adds a social element to your AI queries.

A group of researchers covertly ran a months-long "unauthorized" experiment in one of Reddit's most popular communities using AI-generated comments to test the persuasiveness of large language models. The experiment, which was revealed over the weekend by moderators of r/changemyview, is described by Reddit mods as "psychological manipulation" of unsuspecting users. "The CMV Mod Team needs to inform the CMV community about an unauthorized experiment conducted by researchers from the University of Zurich on CMV users," the subreddit's moderators wrote in a lengthy post notifying Redditors about the research. "This experiment deployed AI-generated comments to study how AI could be used to change views." The researchers used LLMs to create comments in response to posts on r/changemyview, a subreddit where Reddit users post (often controversial or provocative) opinions and request debate from other users.

Reddit users who were unwittingly subjected to an AI-powered experiment have hit back at scientists for conducting research on them without permission – and have sparked a wider debate about such experiments. The social media site Reddit is split into "subreddits" dedicated to a particular community, each with its own volunteer moderators. Members of one subreddit called r/ChangeMyView, because it invites people to discuss potentially contentious issues, were recently informed by the moderators that researchers at the University of Zurich, Switzerland, had been using the site as an online laboratory. The team's experiment seeded more than 1700 comments generated by a variety of large language models (LLMs) into the subreddit, without disclosing they weren't real, to gauge people's reactions. These comments included ones mimicking people who had been raped or pretending to be a trauma counsellor specialising in abuse, among others.

Earlier this month, we heard rumblings that Google had plans to launch a more child-friendly version of its AI chatbot Gemini, and now 9to5Google reports that the tech giant has confirmed in an email to parents that the kids' version of Gemini is officially in the works. Children under the age of 13 will be able to start using Gemini in the coming months via a supervised account, and parents will be able to manage their children's usage via Google's Family Link app. Google says Gemini can help children with homework and creative endeavors like making up stories, but also points out that Gemini can indeed make mistakes. The tech giant wants parents to teach children never to enter personal information into the chatbot, and to think critically about Gemini's answers and always double-check responses. Even though it sometimes talks like one, it can't think for itself or feel emotions," Google writes in the email to parents, who can disable Gemini access for their kids via the Family Link app or website.

Yelp has announced new AI-powered call answering features for restaurants and services as part of its Spring Product Release. With the service, currently under development, the company hopes that "businesses never have to miss a call again." "In this next step of our product transformation, we're continuing to harness AI to unlock the potential of Yelp's rich data in ways that build trust and simplify decision-making -- whether users are hiring a pro or booking a reservation," Yelp's chief product officer, Craig Saldanha, said in a statement. "By grounding our AI in real consumer behavior and business data, we're creating intuitive, transparent features that improve the experience for everyone on Yelp." The AI-powered system "will be fully integrated into Yelp's platform with customizable features and the ability to answer general questions, filter spam, transfer calls when needed, and capture messages."

The current U.S. administration has launched a wara on academia. Indirect costs, or, more accurately, facility and administration expenses, support research but cannot be directly attributed to a specific project, such as lab infrastructure, utilities, and administrative support. These are real costs; the limit, which has since been suspended by courts, is a severe blow to biomedical research in the U.S. Beyond expanding this limit to other agencies, such as the National Science Foundation (NSF), the administration is also reportedly considering slashing NSF's annual budget from approximately US 9 billion down to about US 3– 4 billion. This would deal a devastating blow to academic U.S. research, especially computing research. As statedc by the Computing Research Association (CRA), "NSF budget cuts would put the future of U.S. innovation and security at risk."

Russia has rejected a proposal from Ukraine to extend Russian President Vladimir Putin's unilateral three-day ceasefire as the United States grows increasingly impatient with stalled efforts to find a long-term solution to end the war. Kremlin spokesman Dmitry Peskov confirmed on Tuesday that Moscow had seen Ukrainian President Volodymyr Zelenskyy's offer to extend Putin's brief early May pause in fighting to 30 days. But Peskov said it would be "difficult to enter into a long-term ceasefire" without first clearing up a number of "questions". Zelenskyy had branded Putin's unilateral truce, which will last from May 8 to 10 and coincides with Moscow's celebrations to mark the 80th anniversary of its victory over Nazi Germany in World War II, as an "attempt at manipulation". The Ukrainian leader also questioned why Moscow would not agree to Kyiv's call for a ceasefire lasting at least 30 days and starting immediately.

OpenAI, which spends far more money than it takes in, is trying something new to stanch the bleeding. The company just announced that all users, including on the free tier, can shop from ChatGPT Search. "You can now search for a product, compare options and buy products in ChatGPT," OpenAI said in a press release. Categories currently available include fashion, beauty, home goods and electronics, with expansion to more categories set to come later. The search results you'll obtain are "chosen independently and are not ads," the company promises. The updates are available in 4o and are rolling out to ChatGPT Plus, Pro, Free and even logged-out users.

In at least one crucial way, AI has already won its campaign for global dominance. An unbelievable volume of synthetic prose is published every moment of every day--heaping piles of machine-written news articles, text messages, emails, search results, customer-service chats, even scientific research. Chatbots learned from human writing. Now the influence may run in the other direction. Some people have hypothesized that the proliferation of generative-AI tools such as ChatGPT will seep into human communication, that the terse language we use when prompting a chatbot may lead us to dispose of any niceties or writerly flourishes when corresponding with friends and colleagues.

Duolingo is now going to be "AI-first," the company has announced -- aka it will drop employees in favor of using AI. In a publicly shared email, CEO Luis von Ahn outlined how Duolingo will "gradually stop using contractors to do work that AI can handle." This follows the company's January 2024 decision to cut 10 percent of its contractors, in part because AI could do their tasks. In the email, von Ahn points to Duolingo's "need to create a massive amount of content, and doing that manually doesn't scale. One of the best decisions we made recently was replacing a slow, manual content creation process with one powered by AI. Without AI, it would take us decades to scale our content to more learners. We owe it to our learners to get them this content ASAP."
