Main AI News:
In the midst of the AI renaissance, Princeton University has embarked on a pioneering endeavor aimed squarely at harnessing the potential of Large Language Models (LLMs) for academic and research purposes. Known as the Princeton Language and Intelligence Initiative (PLI), this ambitious program seeks to cultivate a profound understanding of large AI models, facilitating their application across a diverse array of academic disciplines. Moreover, it endeavors to dissect the societal and ethical implications of AI, with a keen focus on developing strategies to mitigate potential harms. PLI, as outlined on its official website, aspires to be not only a crucible of collaboration for students, researchers, and faculty members spanning various fields but also a driver of local computing infrastructure development, replete with dedicated equipment and personnel.
The mantle of leadership for this groundbreaking initiative has been assumed by Sanjeev Arora, the Charles C. Fitzmorris Professor of Computer Science and a distinguished authority in theoretical computer science and machine learning. The cornerstone of PLI’s mission revolves around the exploration and scrutiny of large language models, which constitute a pivotal category of AI systems. These models, fueled by an extensive corpus of textual data, are engineered to excel in natural language processing (NLP) tasks, including text recognition, translation, and predictive text generation. Among the eminent AI tools powered by LLMs is OpenAI’s ChatGPT, which made its debut in November 2022. PLI aims to delve into the myriad promises and potential pitfalls these LLMs bring to academic and societal contexts.
According to Sanjeev Arora and University Provost Jennifer Rexford ’91, the genesis of PLI, from conception to its formal inauguration, spanned approximately one year. The sudden surge in popularity of LLM-based chatbots, such as ChatGPT, expedited the initiative’s inception. As PLI charts its course toward adapting AI for research-centric applications, it may take the audacious step of crafting its own LLMs tailored to the specific demands of Princeton researchers across various domains.
In a candid interview with The Daily Princetonian, Sanjeev Arora elucidated the potential benefits of having a locally embedded computing infrastructure, equipped with proprietary LLMs at the disposal of Princeton researchers. He emphasized the need for intelligent processing beyond mere text search, highlighting the cost-effectiveness and legal viability of local data processing, particularly when dealing with proprietary data.
The official launch of this transformative initiative, christened AI@Princeton, unfolded in McCosh Hall 50 on the afternoon of Tuesday, September 26. Distinguished voices, including Rexford, Arora, and other faculty members hailing from fields as diverse as computer science, psychology, and classics, converged to deliberate on the mechanics of LLMs and their adaptability to elevate individual disciplines. Furthermore, they candidly addressed the societal risks and challenges entailed by these remarkable models.
During his presentation, Arora announced a substantial computing budget of $10 million that PLI is poised to harness in its quest to unravel the vast potential of AI.
PLI’s mission inevitably aligns with the objectives of other Princeton entities, such as the Center for Digital Humanities (CDH), the Center for Information Technology Policy (CITP), and the Center for Statistics and Machine Learning (CSML). This synergy is poised to foster collaborative endeavors that explore the frontiers of AI and its far-reaching impacts.
In her conversation with the ‘Prince,’ Jennifer Rexford underscored the imperative for PLI to navigate the ever-evolving landscape of AI while positioning itself relative to the industry. She acknowledged the challenges in securing government funding for nascent projects and expressed optimism that a successful PLI could unlock opportunities for federal funding, foundation support, and more, thereby ensuring sustainability without continuous central University backing.
Meredith Martin, Associate Professor of English and Faculty Director of the Center for Digital Humanities (CDH) shed light on the transformative potential of PLI in terms of human and organizational dynamics. The prospect of a smaller institution like Princeton accessing abundant resources could potentially catalyze swifter advancements and novel approaches in AI research, enriching the academic tapestry.
Both Arora and Martin hinted at Rexford’s instrumental role in securing approval for PLI from the Board of Trustees. Rexford, in her capacity, emphasized PLI’s role in tackling issues that corporations are often disinclined to invest in, including research projects in the humanities and the pressing question of how to adequately evaluate and govern large language models.
Notably, PLI’s bid to acquire state-of-the-art graphics processing units (GPUs) serves as a stark testament to the insatiable demand for cutting-edge semiconductor chips, particularly those manufactured by the Taiwan Semiconductor Manufacturing Company (TSMC). According to Arora, GPUs, such as the highly sought-after Nvidia H100 GPUs, have already been pre-sold before their production, reflecting the fervent race for computational power. This underscores the imperative for PLI to secure the necessary hardware to power its pioneering AI research efforts.
Conclusion:
Princeton’s PLI initiative signifies a strategic move towards harnessing AI’s potential for academic and research pursuits. By investing in LLM research and computing infrastructure, Princeton is positioning itself as a frontrunner in AI-driven advancements, offering a glimpse into how academia can adapt to the AI revolution. This initiative could potentially lead to groundbreaking discoveries, enriching the market for AI solutions and research collaborations in the academic and corporate sectors.
