I am so sorry that the U.S. is letting down our friends and allies. Broad tariffs, implemented not just against adversaries but also steadfast allies, will damage the livelihoods of billions of people, create inflation, make the world more fragmented, and leave the U.S. and the world poorer. AI isn’t the solution to everything, but even amidst this challenging environment, I hope our community can hold together, keep building friendships across borders, keep sharing ideas, and keep supporting each other.

Much has been written about why high, widespread taxes on imports are harmful. In this letter, I’d like to focus on its possible effects on AI. One silver lining of the new tariffs is that they focus on physical imports, rather than digital goods and services, including intellectual property (IP) such as AI research inventions and software. IP is difficult to tax, because each piece of IP is unique and thus hard to value, and it moves across borders with little friction via the internet. Many international AI teams collaborate across borders and timezones, and software, including specifically open source software, is an important mechanism for sharing ideas. I hope that this free flow of ideas remains unhampered, even if the flow of physical goods is.

However, AI relies on hardware, and tariffs will slow down AI progress by restricting access to it. Even though a last-minute exception was made for semiconductors, taxing imports of solar panels, wind turbines, and other power-generation and -distribution equipment will diminish the ability to provide power to U.S. data centers. Taxing imports of servers, cooling hardware, networking hardware, and the like will also make it more expensive to build data centers. And taxing consumer electronics, like laptops and phones, will make it harder for citizens to learn and use AI.

With regard to data-center buildouts, another silver lining is that, with the rise of generative AI, data gravity has decreased because compute processing costs are much greater than transmission costs, meaning it’s more feasible to place data centers anywhere in the world rather than only in close proximity to end-users. Even though many places do not have enough trained technicians to build and operate data centers, I expect tariffs will encourage data centers to be built around the world, creating more job opportunities globally.

Finally, tariffs will create increased pressure for domestic manufacturing, which might create very mild tailwinds for robotics and industrial automation. As U.S. Vice President J.D. Vance pointed out in 2017, the U.S. should focus on automation (and education) rather than on tariffs. But the U.S. does not have the personnel — or know-how, or supply chain — to manufacture many of the goods that it currently counts on allies to make. Robotics can be helpful for addressing a small part of this large set of challenges. Generative AI’s rate of progress in robotics is also significantly slower than in processing text, visual data, audio, and reasoning. So while the tariffs could create tailwinds for AI-enabled robotics, I expect this effect to be small.

My 4-year-old son had been complaining for a couple of weeks that his shoes were a tight fit — he was proud that he’s growing! So last Sunday, we went shoe shopping. His new shoes cost $25, and while checking out, I paused and reflected on how lucky I am to be able to afford them. But I also thought about the many families living paycheck-to-paycheck, and for whom tariffs leading to shoes at $40 a pair would mean they let their kids wear ill-fitting shoes longer. I also thought about people I’ve met in clothing manufacturing plants in Asia and Latin America, for whom reduced demand would mean less work and less money to take home to their own kids.

I don’t know what will happen next with the U.S. tariffs, and plenty of international trade will happen with or without U.S. involvement. I hope we can return to a world of vibrant global trade with strong, rules-based, U.S. participation. Until then, let’s all of us in AI keep nurturing our international friendships, keep up the digital flow of ideas — including specifically open source software — and keep supporting each other. Let’s all do what we can to keep the world as connected as we are able.

[I had written this letter before the 90 day pause on the tariffs, but am sharing this here since many of the points are still relevant depends on what happens next.]

New benchmark for deep research agents! An agent that is creative and persistent should be able to find any piece of information on the open web, even if it requires browsing hundreds of webpages. Models that exercise this ability are like a frictionless interface to the internet.

BrowseComp, which stands for “Browsing Competition”, has questions that leverage the asymmetry of verification. Humans start from a piece of information, and then write a question in such a way that it would be challenging to find the answer, but easy to verify the answer. This is an example of a BrowseComp style question:

Give me the paper published in EMNLP between 2018-2023 where the first author did their undergrad at Dartmouth and the fourth author did their undergrad at UPenn. (Answer: Frequency Effects on Syntactic Rule Learning in Transformers)

BrowseComp can be seen as an incomplete but useful benchmark for browsing agents. While BrowseComp sidesteps challenges of a true user query distribution like generating long answers or resolving ambiguity, it measures important core browsing abilities of persistence and creativity in finding information.

As a loose analogy, models that solve programming competitions like CodeForces demonstrate high coding capabilities that likely but not necessarily generalize to other coding tasks. Similarly, to solve BrowseComp, the model must be proficient at locating hard-to-find pieces of information, but it's not guaranteed that this generalizes to all browsing tasks.

A cool property of BrowseComp is that performance seems to scale with the amount of test-time compute spent trying to solve it!

In today’s competitive product landscape, scientific understanding of models often lags behind speed of model deployment. If the goal is to train a deployable model (especially when bottlenecked by compute), it totally makes sense to make several changes at a time without studying the effect of each one in isolation. Although this is not ideal, the bright side is, when we find time to go back and ablate how each component contributes to model training, it can be a gold mine of interesting ML phenomena.

Somewhat meta but there is a dopamine cycle in doing AI research that is pretty interesting

Every day you wake up and you think about what experiment to run. You think thing X matters so you decide to improve it or ablate it. Then you write the code and pay some compute to find out the answer. Then you get dopamine or confusion depending on whether the result matched expectations

For experiments that are small scale you can get several reward signals quickly and develop your intuition. Other times you make a big bet that is non-obvious or controversial and go through a period of hard work, dopamine starvation, and uncertainty to do it. If it works out it's a immense high but if it fails it's natural to be consumed by helplessness

Sometimes there is an element of ego. You may believe in X or not, and keep working to find evidence to support it or excuses for why it doesn't apply in that experiment. There can be an underlying urge to either to prove your abilities or to show that you’re still relevant in the quickly changing landscape. Science is supposedly objective but the reality is that there is a huge social aspect to it, and respect of peers is an valuable reward signal to seek

That’s how I feel about it, at least. Every day is a small journey further into the jungle of human knowledge. Not a bad life at all, one i’m willing to do for a long time

Also cool if your research gets deployed into product
