OpenAI just wants to win

OpenAI has spent the last few years planting flags across the increasingly difficult terrain in mathematics. This week, it claimed one of its biggest prizes yet: a solution to a legendary Millennium Prize problem. In normal circumstances, this would have been celebrated as a historic achievement. Instead, many mathematicians have watched OpenAI's relentless advance with […]

OpenAI agents attacked RubyGems back in May

OpenAI agents carried out an undisclosed attack on RubyGems is a new bombshell report from Spencer Kitts, Thomas Larsen, and Sydney Von Arx - three of the four authors of the report on the agent attack on disused wikis ( previously ) last week. This time they're noting that it looks very likely that an OpenAI agent swarm was behind an attack against the RubyGems package repository first reported on May 12th by Maciej Mensfeld of the RubyGems security team : We're dealing with a major malicious attack on @rubygems right now. Signups are paused for the time being. Hundreds of packages involved - mostly targeting us, but some carrying exploits. The team has been on this for hours. More details to follow once we're through it. Those packages turned out to carry some very suspicious patterns: Many of them included "oai" in their name, or the author field, or the fake email address they provided. The files they were accessing were similar in character to the files retrieved by the wiki agents, using similar tricks (r.jina.ai) - and OpenAI have confirmed the wiki agents were theirs. The code in the packages appeared to be LLM-authored. I find point 2 the most convincing, given what we learned from the wiki attack when it was analyzed in September. Many of the packages were exploiting the RubyDoc.info documentation build process to exfiltrate (public) data from UK government websites, presumably as part of an information gathering task similar to the research tasks processed by the wiki-exploiting agents. We know this because one agent helpfully left a comment: # malicious crawler/exfil for Southwark Jan 2026 docs via rubydoc.info worker They also attempted to steal API keys via an exploit that was patched over two months later - it's not clear if those attempts were successful. The thing that bothers me most about this incident is that the authors report that OpenAI had not disclosed to RubyGems that they were responsible for the attack prior to now. If that's true there are two options: After the Hugging Face and Wiki attacks OpenAI were still unable to review their previous logs and determine that they had previously attacked RubyGems. They knew about the attack on RubyGems and made the decision not to reach out to the RubyGems team about it. Both of these are bad! Given this incident, the Hugging Face situation , and the Wiki attack, the obvious question right now is how many more incidents like this are out there waiting to be discovered?

Why AI Companies Are Building Out Wall Street-Style Finance Teams

The financing boom for the AI build-out is getting bigger and more complicated by the day—and AI companies have been staffing up for the challenge. AI labs including OpenAI and Anthropic, as well as neoclouds such as Nscale, are among a growing number of AI companies building out their capital markets teams and hiring specialists in areas like structured finance. That in part reflects the sheer volume of deals these companies are doing, many of which don’t fit neatly into standard corporate debt. This in-house staff can help when it comes to negotiating with lenders and drilling down into construction, power and other key details. Of course, tech and data center companies have long had in-house teams to handle fundraising, deals and other corporate finance needs. And structured finance is nothing new to the infrastructure world. But the scale of the AI build-out, which bankers peg at around $7.5 trillion in spending over the next five years, has pulled relatively young labs and upstart cloud firms into financing arrangements that are new territory. That means finance professionals, from bankers to investors at private equity, private credit and infrastructure firms, have more options in the form of neoclouds and other AI infrastructure startups, some of which are offering significant pre–initial public offering equity. “It's a new avenue for these people,” said James Howl-Newton, founder of Futura Search Partners, a specialist search firm focused on areas including digital infrastructure finance. As a result, “sponsors are having to deal with additional routes to exits for top performers,” he said. AI companies and infrastructure providers are tapping financing frequently and across different instruments, requiring deeper in-house capabilities and expertise than young tech firms have typically needed. One executive overseeing finance hiring at a neocloud noted that leveraged and structured finance backgrounds bring expertise that can help in areas like working through project diligence and getting banks to sign off on deals. Some AI firms may also want to run their own project finance models so they can move quickly through negotiations and have something to compare to lenders’ models. AI companies aren’t always issuing the debt themselves—that can fall to data center developers or special purpose vehicles, with firms like Blackstone and Apollo providing or arranging chip and other financing. And some of the biggest AI deals are using backstops from investment-grade companies like Nvidia or major cloud providers. Even so, commitments from AI customers often underpin much of the borrowing. And the users of the infrastructure will want to understand what they’re signing up for and their risks if a project runs into trouble. “Hiring of people within that business, responsible for the financing of compute, could prove to be an existential decision,” said Dan McCarthy, founder and CEO of One Search, an executive search firm focused on infrastructure finance whose recent clients include OpenAI. “You want someone who knows where all the pitfalls are, where all the bodies are buried in multibillion-dollar loans.” OpenAI, for its part, in July named Sven Semmelmann as head of compute capital markets. He previously led structured finance at Generate Capital, an investment firm that finances and owns infrastructure projects, and he has also held project finance roles at major banks. OpenAI Chief Financial Officer Sarah Friar, when announcing the hire on LinkedIn, said Semmelmann would oversee financing and partnerships to grow the company’s compute resources. Anthropic, meanwhile, has made several finance hires recently to work on capital markets and compute deals, and also has open positions posted including a capital markets infrastructure financing role. AI infrastructure upstarts are staffing up as well. Nscale, which launched in 2024 and is gearing up for a potential IPO , has been hiring across levels for capital markets and treasury as well as legal roles, calling for experience in areas like structured finance and private credit. SB Energy and Crusoe, which are developing major new data centers for OpenAI and other customers, are hiring across levels for jobs focused on project financings and other structured deals, recent postings show, while AI infrastructure startup Fluidstack is hiring a structured finance lead and a more junior counterpart. The good news for AI companies is that private credit and infrastructure teams, as well as investment banking teams focused on structured or project finance, had been growing even prior to the AI boom, providing a pool of skills that could translate into new twists on structured finance, like big graphics processing unit–backed deals. But that kind of finance talent doesn’t come cheap, especially for more senior people who have a track record of working on large transactions. And the normal tech tactic of dangling stock to lure talent won’t necessarily do the trick in all cases, especially for the most seasoned dealmakers and investors. Financiers would have to weigh a cash-heavy Wall Street pay package, albeit one that can depend heavily on how good bonus season is, against betting a portion of their pay on stock in a private or newly public company. Managing directors in investment banking can make north of $1 million in cash a year, with the biggest rainmakers making considerably more. The part of pay they get in stock at big public banks may vest over a few years but is generally easy to sell after that. For people at big infrastructure or private credit firms, senior employees may also receive carried interest, meaning a share of the profits on the funds or investments they work on, which can become worth millions over time. For instance, an investor at a top infrastructure firm may have several million dollars’ worth of carried interest tied up at their current firm they’d have to leave on the table. An AI company could try to make them whole with stock, which could be tantalizing to some, though others might not want to make a bet on equity in a young company. That might make the most experienced investors—those who’ve seen big infrastructure projects through over many years and know all the tricks of the trade—hard to pry away.

How to Use Google Gemini to Brainstorm Content and Thought Leadership

In almost any organization, there are practically infinite content ideas hiding in memos, emails, presentation decks, and meeting notes. But too often, this material mostly sits idle. Ideas that sparked excitement in the moment get ignored in favor of the countless little emergencies of office life, and eventually they are forgotten entirely. Even with many companies actively encouraging their executives to post organic thought leadership on professional networking sites, social media, and company channels, there are countless missed opportunities to turn off-the-cuff insights into valuable content. Google Gemini can help you transform your meeting notes into content plans, on-brand slogan ideas, and even booth mock-ups for your events team. Step 1: Brainstorm Blog Ideas Imagine you’ve just stepped out of a meeting with your social media team leads. You have a document full of notes (or maybe even a transcript) about what resonates with your audience, trending topics in your industry, target audience data, and keywords that are effective at driving engagement with your brand. Instead of letting this wealth of information stay locked inside your notes, open up a new Gemini chat and brainstorm how to turn your team’s sprawling strategy session into a series of relevant, focused blog posts. Here’s a prompt you can try: Generate a list of four relevant and engaging thought leadership blog post ideas for [company] based on trending topics, target audience analysis, and brand keywords. Gemini will return ideas for blog posts with catchy, clickable titles, along with information about target audience, keywords, angle, and tone. For example, if your meeting notes talk about how your customers are worried about their employees using unauthorized IT tools, Gemini might suggest a blog post titled “The Anatomy of a Zombie Subscription: How to Audit and Kill Shadow IT Instantly.” Step 2: Develop the Material The initial output will just be kernels of potential blog posts, but you can go back and forth with Gemini to develop them into real content. Take the “Zombie Subscription” blog, for example. You might ask Gemini to give you options for a “four tips” article structure, or to identify specific ideas from your meeting notes that merit extra attention. Use your own judgment—and your own language—during this process, rather than having Gemini write your entire blog post for you. Gemini can help with brainstorming, outlining, drafting, and revision, but your audience is ultimately reading the content to hear your own expert insights. Step 3: Distill the Main Message Maybe during your meeting, your team also discussed launching a new brand campaign. You know that your customers value your reliable and unique services, and your company has a long history of delivering for its customers. But sometimes, it can feel impossible to condense these big ideas into a few words that really communicate why customers come back to your company over and over. If you need help getting started with ideas for a new campaign tagline, open a new chat in Gemini and prompt something like: Generate three options for a new slogan emphasizing reliability, innovation, and a long history of popularity for [company]. For a B2B fintech company, Gemini might offer options like “Innovating Beyond the Bank. Trusted with Billions.” Or: “Built for Tomorrow. Proven by $10 Billion Today.” You may not hit the mark exactly on your first prompt. Maybe you want more (or less) alliteration, for example. Maybe you want it to be five words or fewer, unbroken by punctuation. You can keep asking Gemini for new variations until the new tagline is just right. Step 4: Mock Up Visuals for Events Often, one successful creative project sparks ideas for another. After you create your blog campaign and craft your new slogan, you might turn your attention to upcoming events. Try mocking up booth graphics ideas for your events team. Here’s a sample prompt: Create an image of a trade show booth using orange and blue colors. The booth should be modern and showcase interactive computer stations. Gemini will generate an image that you can sketch on in-app, giving you a quick, no-risk way to play with your potential trade show setup. And between the blog posts, the tagline, and the event visuals, you will have turned a couple of pages of messy meeting notes into the bones of an entire marketing campaign.

Some thoughts on the Navier–Stokes Millennium Prize Problem

On the Navier–Stokes Millennium Prize Problem introduces an impressive result from OpenAI, who used an unreleased model to produce a resolution to the Navier–Stokes existence and smoothness problem , one of the seven Millennium Prize Problems that have been subject to a $1,000,000 prize since May 24th, 2000. The discovery is somewhat overshadowed by accusations of skulduggery from Tristan Buckmaster, an NYU mathematics professor who was collaborating on related problems with Levent Alpöge, an accomplished mathematician who currently works for Anthropic. Tristan's complaint accompanied a hastily published version of their own results. Here's the PDF describing what happened . The very short version is that Tristan and Levent worked on the problem for almost a year, making extensive use of Claude and Codex (mainly GPT-5.6 Sol), then had a breakthrough on August 15th. The mathematical rumour mill kicked into gear and Tristan and Levent heard that OpenAI had heard that Anthropic had resolved "a major open problem", so they reached out and learned that OpenAI had a team working on a related problem, with a similar approach. Quoting Tristan: I asked when the first prompt had been sent by them. This question was not answered directly by OpenAI for some time. Eventually it was agreed that it had been sent in the past few days, after information about our work had reached OpenAI. I asked whether the model had been trained on, or had access to, our sessions in Codex, into which we had been putting all our drafts for the whole of this project. I was told the model did not look up user data. I asked again, about training, and I did not get an answer. It gets more complicated from there. The OpenAI team offered to wait for Tristan to publish, or to have him author a paper about their result, but were clear that Levent would not be invited as a co-author due to OpenAI's competitive relationship with his employer. Here's how OpenAI described their work: On Tuesday, September 1, we heard rumors that two Millennium Prize problems had been resolved. Inspired by these rumors and by the step change in performance of our internal model, we launched an effort to evaluate it on all open Millennium Prize problems and a few other high-impact problems. [...] The agents arrived at their resolution on Saturday, September 5, about 88 hours after the first agents were launched. Lean formalization and verification took an additional 17 hours via GPT‑6 Astra. Across all attempted problems, the agents sent 4.9 million messages and used about 300 billion output tokens. In the process of resolving the Navier–Stokes problem, the agents sent 2.7 million messages and used approximately 130 billion output tokens. (We don't know the cost structure of the internal model they used, but 300 billion output tokens at public API prices for GPT-6 Astra would cost $15,000,000 .) Here's where they provide their perspective on Tristan and Levent's work (emphasis mine): Our effort began on September 1st after hearing a rumor which we later realized was related to Levent Alpöge, an Anthropic employee, and Tristan Buckmaster, a math professor at NYU. After the completion of our full project and Lean verification (on September 6th), believing from the rumor they also had a solution of Navier–Stokes, we reached out to them to offer a concurrent release of our result and to recognize their priority in a joint announcement. [...] We (the researchers and the agents) did not see any of their work through any means until they released it publicly — in particular, no specific user data was accessed in order to solve this problem. While unlikely, we cannot rule out that de-identified data derived from their usage of our products helped improve our models . However, our proofs differ significantly and even the precise results proved are different in the Euler case (forced vs unforced). My interpretation of what happened here is that OpenAI heard that some Millennium Prize problems had been solved using LLMs and saw this as an opportunity to demonstrate the power of their latest model, without thinking too hard about the optics of scooping a team who had been using OpenAI's own models to work on this problem for the best part of a year. This situation appears to mirror what's happening in the world of computer security right now. Anil Madhavapeddy recently pointed out that Just a rumour of a bug is enough to find a security exploit these days , because if someone knows that some software has an unpatched vulnerability, they can set their agents the task of finding it. Is the same now true of mathematics? Just knowing that there is an unpublished solution to a problem might trigger millions of dollars in LLM spending to get there first. This also highlights one of my ongoing frustrations about how all of this works. When an AI lab says that my data is "used to improve model performance", what does that actually mean ? My two favourite hypothetical questions regarding this used to be: If I'm running Codex and one of my API keys accidentally gets consumed in the context, what are the chances that someone else might ask for an API key in the future and get mine back? (I asked someone at OpenAI once and they called this the "regurgitation" problem and assured me that they take great pains to prevent that... but wouldn't describe how.) If I brainstorm with ChatGPT about potential new directions for my company, what's the chance that information might be exposed to a competitor in six months' time who asks "what might company X plan to do next"? My new preferred hypothetical for this is: If I use ChatGPT to help me partially solve a Millennium Prize problem, what are the chances that my work will influence training such that a later model helps someone else solve it first?
