					<description><![CDATA[The Simons Foundation, Anthropic and OpenAI have committed $15 million to help mathematicians evaluate AI-assisted results, learn new tools and set community standards for AI use.]]></description>
										<content:encoded><![CDATA[<p>The Simons Foundation announced on October 15, 2026, a sweeping new set of initiatives designed to help the mathematics community absorb, evaluate and ultimately shape the rapid advance of artificial intelligence in mathematical research. In a striking partnership, the Simons Foundation, Anthropic and OpenAI together will commit fifteen million dollars in combined funding and resources, an effort aimed squarely at the question that now shadows every seminar room and preprint server: how should a discipline built on rigorous proof respond to tools that can generate conjectures, draft arguments and even complete formal demonstrations at machine speed?</p>
<p>The structure of the program reflects a deliberate philosophy about who should hold the steering wheel. The Simons Foundation will manage and award the funding, which will include an open call for proposals, and will direct the money toward workshops and community initiatives that help researchers evaluate recent AI-assisted results, learn and master new tools, share perspectives across subfields and craft collective standards for how AI belongs in the mathematical workflow. In other words, the aim is not simply to hand mathematicians software, but to build the social and intellectual infrastructure that lets a community decide, together, what counts as trustworthy mathematics in an era when the boundary between human and machine contribution is blurring.</p>
<p>Simons Foundation President David Spergel framed the moment as a turning point for the discipline.</p>
<p>The significance of the fifteen-million-dollar commitment becomes clearer when placed against the backdrop of how artificial intelligence has already begun to reshape the day-to-day practice of mathematical research. Over the past several years, large language models and automated reasoning systems have moved from curiosities to working tools that appear in seminars, collaboration threads and preprint acknowledgments. Mathematicians now routinely encounter machine-generated conjectures, computer-searched examples and AI-drafted proof sketches, and the community has had to improvise norms for checking, attributing and discussing such contributions. The Simons Foundation initiative is designed in part to replace that improvisation with deliberate, community-wide deliberation, funding the gatherings and collaborative structures through which working mathematicians can compare experiences and converge on shared expectations.</p>
<p>A crucial feature of the announcement is the role assigned to Anthropic and OpenAI, which will provide AI tools and computing resources to researchers supported by the foundation. This in-kind component extends beyond mathematics to basic science more broadly, reflecting the recognition that the challenges mathematicians face are shared by researchers across the computational and experimental sciences. Access to frontier models and serious computing capacity has been unevenly distributed across the research community, with many mathematicians working at institutions that lack the infrastructure to explore state-of-the-art systems. By channeling these resources through a philanthropic intermediary rather than distributing them directly, the arrangement attempts to preserve a measure of independence: the foundation manages and awards the funding, while the companies supply capabilities that researchers can put to the test in real research settings.</p>
<p>The community-driven framing of the awards is not incidental. Spergel emphasized that the community itself should be driving discussions of how these tools are evaluated, adopted and used, rather than any single company or institution. This positioning speaks to a concern that has circulated widely among researchers: that the norms governing AI in scholarship might otherwise be set unilaterally by the technology companies building the systems, or by a handful of well-resourced universities. By placing decision-making in the hands of an open call for proposals reviewed through a foundation with long-standing ties to the mathematical community, the program attempts to ensure that the direction of travel reflects the priorities of working mathematicians themselves, from those formalizing classical results to those probing whether machine assistance can open genuinely new territory.</p>
<p>The foundation&#8217;s history gives this effort a distinctive foundation to build upon. Long before the current wave of generative models, the Simons Foundation was an early backer of machine learning for science, and among its most consequential bets was funding the development of the Lean proof assistant. Lean is a piece of software that checks mathematical proofs with absolute rigor: every logical step must be justified in a formal language the computer can verify, leaving no room for the small gaps, suppressed cases and courteous hand-waving that can slip into even careful human writing. What began as a niche tool has grown into a global ecosystem, with mathematicians collaborating on vast digital libraries of formalized results and using Lean to verify arguments that would otherwise take referees months to check with confidence. It is precisely this infrastructure, the announcement notes, that has made AI-assisted proofs possible, because a machine-generated argument only becomes mathematics once a proof assistant can certify that every step follows from the last.</p>
<p>The interplay between formal verification and large language models is one of the most consequential developments the new program will confront. Language models are impressively fluent but unreliable in exactly the way mathematics cannot tolerate: they can produce plausible-sounding arguments that contain subtle errors. Formal proof systems are rigorous but laborious, demanding enormous effort to translate even a page of conventional mathematics into machine-checkable form. The frontier of the field now lies in combining the two, letting models propose steps and search for constructions while proof assistants hold them to a standard of certainty. A growing international effort has taken on ambitious formalization projects, and recent years have seen the first substantial research results whose proofs were completed with significant machine assistance. Workshops funded under the new initiative could accelerate this convergence, training more mathematicians in formal methods while giving model developers direct exposure to the demands of genuine research mathematics.</p>
<p>Beyond verification, the initiative addresses a quieter but equally important question: what happens to the practice and culture of mathematics when machines enter the loop. Spergel&#8217;s remark that mathematics should be viewed not as a collection of proofs and theorems but as a collective understanding driven by human curiosity captures a tension many researchers feel. Proof is the discipline&#8217;s standard of certainty, but the life of the field lies in intuition, taste, exposition and the shared conversation through which understanding spreads. If machines begin to supply more of the proofs, the community must decide what remains distinctly human in the enterprise, and how to train the next generation so that reliance on tools deepens rather than atrophies mathematical judgment. Funding workshops where researchers can share perspectives is a mechanism for working through those questions openly rather than leaving them to be settled by default.</p>
<p>The evaluation of AI-assisted results presents another concrete challenge the program targets. Journals and conferences across the mathematical sciences are still developing policies for disclosures about machine involvement, and referees face new difficulties when assessing work that may have been produced or checked with AI tools. Errors in machine-assisted work can be harder to spot, both because the provenance of individual steps may be opaque and because reviewers may extend to generated arguments a trust that rigorous formal checking would otherwise justify. Collective standards, developed through community discussion rather than imposed journal by journal, offer a path toward consistency: shared expectations about when formal verification is required, how machine assistance should be credited, and what level of human oversight constitutes due diligence. The initiative&#8217;s emphasis on helping researchers evaluate recent AI-assisted results suggests a recognition that the community needs not only new tools but new habits of critical reading.</p>
<p>The open call for proposals also functions as a broadening mechanism. Mathematics has long prided itself on the accessibility of its problems, but access to frontier AI tools risks becoming stratified by institution and geography. A researcher at a small college or in a lower-income country may have deep expertise and no route to the systems now shaping the field&#8217;s frontier. By structuring the awards as an open competition and coupling them with provided computing resources, the program creates channels through which talent anywhere in the community can engage with the technology. That breadth matters for another reason: standards forged by a narrow slice of the profession would carry less legitimacy than ones hammered out by a community that includes its full range of practitioners, from applied mathematicians to logicians, from early-career researchers to those who built the field&#8217;s existing formal traditions.</p>
<p>There is also a signal in the timing. The announcement arrives at a moment when the pace of AI capability improvement is outstripping the deliberative speed of academic institutions. Curricula, refereeing practices, hiring norms and funding structures all evolve slowly, while the tools available to a graduate student change month to month. Initiatives of this kind, which fund convening and coordination rather than only individual research projects, represent an attempt to close that gap, giving the community dedicated space and resources to keep pace. The foundation&#8217;s stated aim of supporting workshops, lectures and collaborations continues a convening role it has played for years, having previously brought mathematicians together to explore and discuss AI&#8217;s role in the field through earlier gatherings and partnerships.</p>
<p>For researchers across the sciences, the structure of this effort may prove as instructive as its subject. It treats the introduction of a transformative technology not as a procurement problem but as a governance challenge, one whose solution requires deliberation, shared standards, broad access and a commitment to keeping the affected community in charge of its own norms. Whether the fifteen million dollars proves sufficient to the scale of the transformation remains to be seen, but the program establishes a template for how a scientific discipline might meet a new technological era: by coming together, as Spergel put it, to forge the best path forward, with the mathematicians themselves, not their tools, holding the compass.</p>

					<description><![CDATA[A Perspective in National Science Review argues that legal artificial intelligence must move beyond prediction toward interpretability, reliability, and the embedding of judicial values into model design.]]></description>
										<content:encoded><![CDATA[<p>Artificial intelligence has become remarkably adept at the mechanics of law. Modern systems can search millions of cases in seconds, extract legal knowledge from dense statutory text, and predict how courts are likely to rule on a given dispute. Yet a prediction, however accurate, is not the same thing as a legal justification. When an algorithm is deployed in legislation, law enforcement, or adjudication, the people affected must be able to understand whether its output actually aligns with legal reasoning and with the fundamental values that underpin the judicial system. That gap between statistical performance and normative accountability is the central concern of a new Perspective published in National Science Review.</p>
<p>In the article, Fang Wang reviews the two great paradigms of legal computability and argues that the field must move beyond mere technological empowerment toward a deeper integration of normative values with technological innovation. The argument arrives at a moment when courts and law firms around the world are adopting artificial intelligence at unprecedented speed, raising urgent questions about whether these tools can be trusted with decisions that shape liberty, property, and justice itself.</p>
<p>The dream of making law computable is far older than computing. The seventeenth-century philosopher and mathematician Leibniz envisioned legal rules expressed in symbolic form, so that conclusions could be derived through logical operations much like geometry. The advent of computers in the mid-twentieth century revived this vision and gave rise to rule-based reasoning, in which legal knowledge was encoded as formal rules and applied to facts through deduction. But law, unlike mathematics, does not rest on universally accepted axioms. Many legal concepts resist full formalization, and legal systems contain inherent inconsistencies and gaps. These structural limitations make it difficult, and often impossible, to derive sound legal conclusions through purely formal logical deduction alone.</p>
<p>A second, empirical paradigm emerged instead from real-world legal data, and it has developed along two key directions. Legal Judgment Prediction, or LJP, maps case texts to likely judicial outcomes, answering the question of what result is probable. Empirical Legal Studies, or ELS, examines causal and evaluative questions, helping to explain why particular outcomes occur and supplying evidence relevant to their assessment. Natural language processing has powered this transition: advances ranging from Word2Vec-based word representations and Transformer architectures to today&#8217;s large language models have dramatically improved the ability to process and analyze legal text, laying a technical foundation for downstream tasks such as judgment prediction and empirical legal analysis.</p>
<p>The practical consequences are already visible. In China, the national Smart Court has integrated more than 320 million pieces of legal data records, and the Shenzhen Intermediate People&#8217;s Court launched China&#8217;s first trial-specific large language model in 2024. In the United States, tools such as Harvey AI and CoCounsel are increasingly used by lawyers, and some state courts have begun introducing approved artificial intelligence products. In the United Kingdom, the Ministry of Justice launched an AI Action Plan for Justice in 2025. Legal computing is no longer a laboratory curiosity; it is reshaping the daily practice of justice systems worldwide.</p>
<p>Yet most artificial intelligence models, for all their power, reveal statistical correlations rather than legally sound reasons. The Perspective explains that existing research generally follows two approaches to interpretability: ex ante methods that embed legal logic into model design, and post hoc explanations that attempt to rationalize the behavior of already-trained models. Future systems, Wang argues, could go further by incorporating the logical relations among legal norms, factual elements, and practical reasoning in concrete legal scenarios, and by embedding judicial values directly into model and algorithm design rather than treating ethics as an afterthought.</p>
<p>To that end, the article proposes a value-guided framework situated within a society–law–ethics–algorithms–data system. In this framework, social values can guide model objectives and decision preferences; evolving legal norms can inform model knowledge and reasoning across temporal, spatial, and contextual conditions; and ethical norms can function as executable constraints within the system itself. Possible technical pathways include embedding these values and rules into loss functions, reward modeling, and constrained optimization, while robust optimization and careful constraint design may further strengthen model robustness. High-quality, well-structured datasets, built through bias mitigation mechanisms, are equally essential to ensure the quality of the inputs on which models are trained.</p>
<p>The Perspective also sounds a warning about a subtle psychological hazard: the anchoring effect. When artificial intelligence generates recommendations, those suggestions may bias subsequent human judgment, nudging judges toward algorithmic outputs and creating a path dependence that erodes independent reasoning. Reducing this risk requires a two-pronged response: algorithmic safeguards designed to prevent undue reliance on machine recommendations, and targeted training that strengthens judges&#8217; capacity for independent, critical evaluation of what the algorithm tells them. Trust, in other words, must be earned through design and education, not assumed.</p>
<p>The framework is illustrated through three scenario-specific applications. In intelligent legislation, quantitative simulation and evaluation methods could assess the broader impacts and risks of legal rules, detect inconsistencies and gaps in the law, and support the recording-and-review mechanism for normative documents; quantitative frameworks for the proportionality principle could evaluate whether legislative measures are suitable, necessary, and properly balanced against the rights they restrict. In law enforcement, big-data supervision models in China have identified excessive or inconsistent penalties, while satellite remote sensing has helped procuratorial authorities detect environmental violations; these methods could extend to emerging fields such as data classification, tiered protection, and risk assessment under the Data Security Law, and federated learning offers a way to overcome data silos by enabling collaborative model training without centralizing sensitive data. In adjudication, judicial data could support transparent, explainable systems built around deep human–AI collaboration, in which human judgment retains central authority while algorithms and human expertise co-evolve: as algorithms process the &#8220;is&#8221; data they excel at, they can learn from how humans handle &#8220;ought&#8221; information, keeping computational results aligned with legal reasoning and judicial values.</p>
<p>The article closes with a caution and a note of optimism. Empirical findings are grounded in observed real-world data and should not be mistaken for universally valid truths; the patterns of past cases do not guarantee the justice of future ones. But the Leibnizian pursuit of computable law does not imply permanent infeasibility. Recent studies have begun exploring mathematical proof assistants, including Lean, to formalize and verify legal rules and procedures with machine-checked rigor. Combining empirical learning with formal reasoning, the Perspective suggests, may hold the greatest promise of all: a legal artificial intelligence that not only predicts what courts will do, but can show, in a form humans can verify and trust, why the law justifies it.</p>
