An anonymous reader shared this report from Computerworld: Microsoft has announced Phi-4 — a new AI model with 14 billion parameters — designed for complex reasoning tasks, including mathematics. Phi-4 excels in areas such as STEM question-answering and advanced problem-solving, surpassing similar models in performance. Phi-4, part of the Phi small language models (SLMs), is currently available on Azure AI Foundry under the Microsoft Research License Agreement and will launch on Hugging Face [this] week, the company said in a blog post. The company emphasized that Phi-4's design focuses on improving accuracy through enhanced training and data curation.... "Phi-4 outperforms comparable and even larger models on tasks like mathematical reasoning, thanks to a training process that combines synthetic datasets, curated organic data, and innovative post-training techniques," Microsoft said in its announcement. The model leverages a new training approach that integrates multi-agent prompting workflows and data-driven innovations to enhance its reasoning efficiency. The accompanying report highlights that Phi-4 balances size and performance, challenging the industry norm of prioritizing larger models... Phi-4 achieved a score of 80.4 on the MATH benchmark and has surpassed other systems in problem-solving and reasoning evaluations, according to the technical report accompanying the release. This makes it particularly appealing for domain-specific applications requiring precision, like scientific computation or advanced STEM problem-solving. Microsoft emphasized its commitment to ethical AI development, integrating advanced safety measures into Phi-4. The model benefits from Azure AI Content Safety features such as prompt shields, protected material detection, and real-time application monitoring. These features, Microsoft explained, help users address risks like adversarial prompts and data security threats during AI deployment. The company also reiterated that Azure AI Foundry, the platform hosting Phi-4, offers tools to measure and mitigate AI risks. Developers using the platform can evaluate and improve their models through built-in metrics and custom safety evaluations, Microsoft added... With Phi-4, Microsoft continues to evolve its AI offerings while promoting responsible use through robust safeguards. Industry watchers will observe how this approach shapes adoption in critical fields where reasoning and security are paramount.

Does space need environmentalists, asks the headline from a new article in Noema magazine. "As astrophysicist Neil deGrasse Tyson notes, the first trillionaire will be made in space. "But amid such promising developments are worries among some scientists and environmentalists who fear humans will repeat the errors that resource extraction has wrought on Earth..." If we have mining in space, do we need a preemptive anti-mining campaign to protect our solar system from rampant exploitation before it is too late? Earth-bound environmental advocates and astrobiologists alike have concluded that, indeed, we need an environmental movement in space... [Daniel Capper, an adjunct professor of philosophy at the Metropolitan State University of Denver] is part of a small but growing chorus of intellectuals who argue that we must carve out protections sooner rather than later — backed by a concrete theoretical and legal framework — for certain areas of the solar system. The United Nations has convened a working group on the use of space resources, and the International Astronomical Union has set up a different working group to delineate places of special scientific value on the moon. Some researchers have proposed creating a planetary park system in space, while others advocate for a circular space economy that minimizes the need for additional resources. The nonprofit For All Moonkind is advocating for the protection of space sites of cultural importance, like the Apollo 11 landing site. And the Astra Carta, backed by Britain's King Charles, advocates for making sustainability a key component of space activities... [Martin Elvis, an astronomer with the Center for Astrophysics at Harvard University and the Smithsonian Institution] proposed setting aside 7/8ths of the solar system as wilderness, in a paper published in 2019 in Acta Astronautica that he coauthored with King's College London philosopher Tony Milligan... [T]he lack of norms — clear rules and regulations around space — is one of the most pressing threats to the space environment, advocates say. What might happen, for example, if the United States simply began scooping up asteroids for platinum, or if Blue Origin established a mine at the lunar South Pole without securing consensus from others? "We do not have good answers to those questions right now," Hanlon said. "This is something that I'm really concerned about." Much of the legal basis for the space environmentalism movement is currently contained in just one article of the Outer Space Treaty (OST), said Christopher Johnson, the director of legal affairs and space law at the Secure World Foundation. Article 9 of the OST contains the harmful contamination language and says actors must pay "due regard" to the interests of others. It also stipulates that "harmful interference" with the activities of others must be avoided. Those phrases could be interpreted in multiple ways and have yet to be meaningfully tested. The article cites two concrete proposals moving forward: "The Artemis Accords, a set of principles for exploring and using resources in outer space established by the U.S. in 2020, argues that resource extraction does not constitute national appropriation, and is therefore allowed by the OST. It's an initial step toward securing a consensus on space regulations, and one that's to date received the signatures of 47 nations including Japan, the United Kingdom, France and Germany (though China and Russia are notably absent). Signing the Artemis Accords allows nations to participate in the Artemis program, and also play a role in shaping future norms in space, Johnson said, a potentially lucrative incentive... " "The UN's COPUOS, the same one responsible for the OST and the Moon Agreement, published a working paper in 2019 that laid out voluntary guidelines for the long-term sustainability of outer space activities. Recommendations from the committee's working group on principles for the use of space resources are due in 2027, and Johnson said draft guidelines are likely to emerge in early 2025." "One day, our descendants might live among the stars," the article concludes. "But we must ask ourselves, what kind of place will they inherit?"

They provide training data to top AI companies including OpenAI and Meta, according to its web site. Founded in 2016, San Francisco-based Scale AI now has over 900 employees, eventually growing beyond "unicorn" status with over $1.35 billion in ivnestments. In May the company's valuation was over $14 billion, with investors including Amazon, Meta, Nvidia, Cisco, Intel, and AMD (as well as earlier investments from Y Combinator and $100 million from Peter Thiel's Founders Fund). SFGate calls them "a buzzy San Francisco startup with high-dollar ties across the tech industry". But SFGate also report Scale AI "was sued Tuesday by a former worker with allegations that the company is committing wage theft and misclassifying workers." Steve McKinney filed the suit against Scale and several top executives, including 27-year-old billionaire CEO Alexandr Wang, in San Francisco Superior Court. With the filing, the former contractor aims to be a lead plaintiff for a class-action lawsuit against Scale; a judge will need to certify his proposed class of current and former contractors within California... McKinney, whose complaint says he was paid on an hourly basis and worked on a project eventually sold to Meta, is accusing Scale of amassing its clout and cash by exploiting workers. "Scale AI is the sordid underbelly propping up the generative AI industry," the complaint says, before rattling off a list of allegations about its treatment of contractors. The document accuses Scale of bait-and-switch hiring promises; demanding off-the-clock, unpaid work; denying overtime pay; and unfairly booting contractors from projects... The Tuesday complaint calls Scale's control over its contractors "Orwellian." The company makes contractors download a tool to track much of their computer use, including by taking periodic screenshots, the suit alleges. The lawsuit also alleges that Scale reassigns the workers to varyingly paid projects and docks pay if a task takes more than it was supposed to, plus posits that Scale is in violation of California's "ABC" test, which monitors use of the designation "independent contractor." It argues that contracted "Taskers" like McKinney should be classified as employees instead... The complaint, along with arguing for class-action certification, seeks restitution, punitive damages and changes to Scale's worker classification model. The article adds that "Per Fortune, Scale's armies of contractors marked up images for Cruise and Waymo to help autonomous cars understand their surroundings..."
