Last week, I headed 30 miles south of San Francisco to a hotel in Mountain View, California, to join some of the most accomplished, and some of the most promising, AI researchers in the world. I was hosting roundtable interviews and speaking at a media training for a convening of the Schmidt Sciences AI2050 program, an initiative funded by Eric and Wendy Schmidt that supports academics whose work involves AI. The fellows list is a who’s who of AI luminaries, and though not all of them made it out to the Bay, every time I turned a corner I saw a scientist whom I’d interviewed previously or whose research I admired. (Full disclosure: I received a science communication award funded by Schmidt Sciences in 2024.)
上周,我前往旧金山以南30英里处的加利福尼亚州山景城的一家酒店,与一些世界上最有成就、也最有前途的AI研究人员会面。我主持了圆桌访谈,并在为Schmidt Sciences AI2050项目举办的一次媒体培训上发言。该项目由Eric和Wendy Schmidt资助,支持从事AI相关工作的学者。研究员名单堪称AI名人大全,虽然并非所有人都来到了湾区,但每次我转身都能看到一位我以前采访过或敬佩其研究的科学家。(完全披露:我在2024年获得了由Schmidt Sciences资助的科学传播奖。)
It’s a weird time for university AI researchers, who make up most of the AI2050 group. In the past four years, AI research has reoriented around large language models, and its cutting edge has moved from academic institutions to private companies. Universities simply can’t afford the GPUs required to train and run frontier models, and even if they could, Anthropic and OpenAI aren’t letting anyone else see the inner details of Claude or ChatGPT.
对于构成AI2050项目大部分的大学AI研究人员来说,这是一个奇怪的时期。在过去四年里,AI研究已围绕大语言模型重新定位,其前沿已从学术机构转移到私营公司。大学根本负担不起训练和运行前沿模型所需的GPU,即使他们能负担得起,Anthropic和OpenAI也不会让任何人看到Claude或ChatGPT的内部细节。
In a conversation over lunch, Nika Haghtalab, a computer science professor at UC Berkeley, said that being an AI academic these days was like being a biologist in a world in which private companies had exclusive control over the gene-editing tool CRISPR. Experts outside the frontier labs can study how ChatGPT and Claude behave, but they can’t do any detailed research on the design and training of those tools, nor can they steer that design or training themselves.
在一次午餐交谈中,加州大学伯克利分校的计算机科学教授Nika Haghtalab表示,如今作为一名AI学者,就像在一个私营公司独家控制基因编辑工具CRISPR的世界里当生物学家。前沿实验室之外的专家可以研究ChatGPT和Claude的行为,但他们无法对这些工具的设计和训练进行详细研究,也无法自行引导这些设计或训练。
The AI2050 program does offer fellows some funding that they can use to buy GPUs, which some researchers I spoke with said was a major benefit of participating in the program. But money remains a pressing concern, especially given the reduction of federal scientific funding in the United States. Even for researchers who don’t run local models themselves, the cost of repeatedly querying OpenAI’s, Anthropic’s, and Google’s models in order to study them rigorously can be prohibitive.
AI2050项目确实为研究员提供了一些资金,他们可以用这些资金购买GPU,一些与我交谈的研究人员表示,这是参与该项目的一大好处。但资金仍然是一个紧迫的问题,尤其是在美国联邦科学经费减少的情况下。即使对于不自己运行本地模型的研究人员来说,为了严谨地研究OpenAI、Anthropic和Google的模型而反复查询这些模型的成本也可能高得令人望而却步。
Rather than focusing on advancing capabilities, many fellows aim their attention at questions that are unlikely to be addressed by Anthropic or OpenAI. “I try not to work on problems that I think are gonna be solved by a tech company,” says Anjalie Field, a computer science professor at Johns Hopkins. Companies need to make money, and research questions that have little promise of profit might not be worth investing in—especially if their answers might make the companies look bad. Recently, for example, Field conducted a study in which she found that language models give less sophisticated responses to prompts that are phrased in ways more commonly used by women than by men. It’s difficult to imagine that kind of research coming out of Anthropic or OpenAI.
许多研究员并不专注于提升能力,而是将注意力集中在Anthropic或OpenAI不太可能解决的问题上。约翰霍普金斯大学计算机科学教授Anjalie Field表示:“我尽量不研究那些我认为科技公司会解决的问题。”公司需要盈利,而那些几乎没有盈利前景的研究问题可能不值得投资——尤其是如果答案可能让公司难堪的话。例如,最近Field进行了一项研究,发现语言模型对以女性更常用方式表述的提示词给出的回答不如对男性常用方式的回答复杂。很难想象Anthropic或OpenAI会进行这类研究。
There’s also a huge group of AI academics who don’t work with LLMs at all. Many of them are scientists who build specialized AI models that can analyze data, make useful predictions, or even simulate entire physical systems. Those researchers aren’t necessarily competing with the frontier labs—Google DeepMind’s AlphaFold team, which built a Nobel Prize–winning model that predicts the structures of proteins, was disbanded last month. But they face plenty of their own challenges. At the convening, several voiced concerns about how the widespread ignorance of non-LLM AI was affecting their work. Researchers who build specialized AI tools to help address climate change, for example, sometimes struggle to advocate for their work when so many people believe that “AI” means “energy-guzzling LLMs.”
还有一大批完全不研究LLM的AI学者。他们中的许多人是科学家,构建专门化的AI模型来分析数据、做出有用的预测,甚至模拟整个物理系统。这些研究人员不一定与前沿实验室竞争——谷歌DeepMind的AlphaFold团队上个月解散了,该团队构建了一个预测蛋白质结构的诺贝尔奖获奖模型。但他们面临着自己的诸多挑战。在会议上,几位与会者表达了对非LLM AI被广泛忽视如何影响他们工作的担忧。例如,构建专门化AI工具以帮助应对气候变化的研究人员,当许多人认为“AI”意味着“耗能巨大的LLM”时,有时很难为他们的工作辩护。
All these challenges are changing the landscape of academia: Several prominent academics have recently taken leave from their universities to join frontier labs, and many AI2050 fellows hold industry positions alongside their academic jobs. And in the past six months, yet another threat has emerged. OpenAI’s models have solved a number of real research problems in mathematics, and some experts are worried that humans might not have a future in pure math. One fellow I spoke with said that she was concerned about the mental health of her mathematician peers.
所有这些挑战正在改变学术界的格局:最近几位著名学者从大学请假加入前沿实验室,许多AI2050研究员在学术工作之外还担任行业职位。而在过去六个月中,又出现了另一个威胁。OpenAI的模型已经解决了数学中的一些实际研究问题,一些专家担心人类在纯数学领域可能没有未来。一位与我交谈的研究员表示,她担心数学家同行的心理健康。
But it’s not all doom and gloom. For one thing, empirical science may prove much more difficult to automate than mathematics, because collecting data is an intrinsically slow process. And some researchers see AI mathematicians and scientists as a boon rather than a threat—including Tim Dettmers, a computer scientist at Carnegie Mellon who works to make AI models faster and cheaper to run. AI scientists won’t replace humans, Dettmers says. On the contrary, they could make human scientists far more efficient, so that he and his peers have the chance to pursue all the wild and inspired ideas they might otherwise never have gotten around to.
但这并非全是悲观和沮丧。一方面,实证科学可能比数学更难自动化,因为收集数据本质上是一个缓慢的过程。而且,一些研究人员将AI数学家和科学家视为福音而非威胁——包括卡内基梅隆大学的计算机科学家蒂姆·德特默斯,他致力于让AI模型运行得更快、更便宜。德特默斯说,AI科学家不会取代人类。相反,它们可以让人类科学家变得高效得多,这样他和他的同行就有机会去追求那些他们原本可能永远没有时间去实现的疯狂而富有灵感的想法。
And scientists are a resilient sort. The very resource constraints that prevent them from training frontier models also push them to discover new ways to make models smaller and more efficient, or to explore completely new architectures. If the next big AI breakthrough comes not from a major company but from a scrappy academic lab, I won’t be shocked.
而且科学家是适应力很强的一类人。正是那些阻止他们训练前沿模型的资源限制,也促使他们发现新的方法,使模型更小、更高效,或者探索全新的架构。如果下一个重大AI突破不是来自大公司,而是来自一个不起眼的学术实验室,我也不会感到惊讶。
