I've been teaching a master's course on AI at @UofT 's @munkschool - and I'm excited to share it with you!
One of the best parts has been the calibre of guest lecturers: folks from @AnthropicAI @GoogleDeepMind and @law_ai_. This week, Mark Surman — @mozilla President and one of the most important voices on open source AI — came by and gave us a fantastic walkthrough of how he's thinking about the evolution of the internet to frontier AI, and Canada's role as a middle power.
When I told him about the course, his first reaction: "You should open source it."
So we did. Full syllabus and a couple AI agents and resources we've built together — all on GitHub: github.com/jaxson/ai-policy-…
Covers everything from the AI supply chain to frontier model governance to hands-on prototyping. More materials and agents coming at the end of term.
Feel free to use it, remix it, share it.
And remember a future with plenty of open source AI is a good one!

I think this story is important because it tells us about the future of cybersecurity (and of course what we can do better at Anthropic). But some of the Washington Post story / reaction on X is wrong. A few corrections:
- it didn’t take 12 hours. we saw several days of attempts. After these attempts, they exploited two 3rd party vulnerabilities, one they reported and the other we identified independently (and cut off access)
- nothing came close to our most sensitive systems, like model weights or Claude conversations
- this wasn't an ordinary bug bounty finding – this involved exploiting 3rd parties and accessing data. While this is unusual and out of scope of our safe harbor policy, we’re grateful these issues were found
From my researcher POV, the event is important because I'm concerned this is what the future will look like. Adversaries will use whatever models/tools they can. They’ll target everything with agents 24/7. They’ll hit your dependencies. I think models ~0.5-1 generations behind the current frontier can do this. And these are the dumbest models your adversaries will ever use!
So, what to do? You probably want to red team yourself all the time. Current models are *very* creative. I also think we should redesign software / systems so that you’re fundamentally less exposed. (We put out some research recently on formally verifying software and reducing attack surfaces; my mental model is basically “secure code is cheap to write now, so why not rewrite everything”)
EXCLUSIVE: In less than 12 hours, a group of ex-DOGE cyber researchers were able to penetrate Anthropic’s systems using AI agents — including Slack channels where the most sensitive models are discussed.
This is just weeks after
Anthropic whistleblower Joseph Coxon charged the company w/launching “a hubristic gamble” from a “private company’s Slack.”

OpenAI just dropped four huge results from its secret internal AI model.
1. Math: It solved the Kakeya conjecture in every dimension. Mathematicians had only cracked small pieces before (2D in 2019, 3D in 2025).
2. Computer science: It proved the Exponential Time Hypothesis is false. Hundreds of research papers assumed it was true. Some really hard problems might be solvable much faster than thought.
3. Physics: It proved the theory of the strong force (QCD)—the force holding atoms' insides together—actually works mathematically. Same for a unified version of the Standard Model.
4. Yang–Mills: Along the way, it proved Yang–Mills existence, part of a $1 million Millennium Prize problem.
The math, computer science, and Yang–Mills proofs were all computer double-checked. Top experts are now reviewing everything, including the researchers who proposed the disproved hypothesis and a Nobel Prize winner.
OpenAI says it doesn't want academic credit. The model still isn't public đź‘€
We are announcing three new discoveries in mathematics, computer science, and physics about harmonic analysis, complexity theory, and quantum field theory.

Our newest book is finally here!
Making the Modern Laboratory is a spectacular 504-page hardcover that tells the story of everything in the research laboratory and how it came to be, from pipettes to heat-resistant glass to microscopes and more.
It features dozens of articles (most of which will never appear in print), 100+ full-color images, and original writing from 36 authors. It's printed on Arena Natural Rough paper from Fedrigoni. These books are THICC and would make a great gift for both the science-curious and the working scientist. :)
We have spent the last year working on this project. It has been an insane labor of love. The best way to support our independent science journalism is to buy a copy. <3

Incredibly interesting and exciting.
interpretability might be the most important scientific problem in the world right now, as I don't think we can solve alignment if we don't know what we're building. I think I have good news about it. I co-authored early work in mechanistic interpretability at OpenAI and came away pessimistic, because neural networks appeared to fold into arbitrary tangled knots. years later, I started openai's first large-scale automated interpretability project, finding about 2% of neurons legible with the primitive tools we had
with modern agentic tools and a much closer look, the picture looks totally different. the vast majority in models up to trillions of parameters are legible, and their circuits beautiful. many famous examples of tangled neurons turned out to be misunderstood. The roadblocks I expected mostly aren't there. I now think ambitious interpretability will be solved by the time we need it most, and possibly quite soon, as automated scientists keep improving. it may be a bitter lesson for interpretability: the simple thing, at absurd scale, works

Great for NY!
And, of course, worth noting Canada is going even further with a ~$200M investment into a quantum data centre with Xanadu in Toronto. We can keep ramping up our quantum investments to ensure we play a critical part of this global supply chain.
When the public invests in new tech, the public should benefit.
That’s why our investment in a Quantum Fabrication Lab at NYU includes a first-of-its-kind agreement to give the city seats on the board and a share of the revenue from the lab — all while making our city the quantum capital of the world.Â
We’re creating a new national model for economic development that gives working people a say and a stake.

The stop-motion animation work behind LAIKA’s WILDWOOD (2026) is absolutely insane.
136 handcrafted sets, over 200 practical puppets and 49 animators working across 231 weeks, with some shots producing just 1–4 seconds of animation per week.

We'll be spending a lot more time trying to understand the outputs of language models. A few thoughts, tips & tricks:
Writing. Something I've had success with: Ask your LLM to explain something in ASD-STE100, it's a controlled language specification originally developed for aerospace maintenance documentation. LLMs well-versed in this language and it comes with heavy constraints on clean writing style that I often find a lot more readable. Sometimes I've tried to soften it a bit e.g. ask for "80% of the way to ASD-STE100" because the spec is quite stringent. But even better:
Diagrams / images. Instead of writing, ask your LLM to create a diagram. These can be a lot easier to process, parse, and understand. But even better:
Web pages. Ask for output "in HTML" to get a beautiful, interactive webpage. LLMs are getting really good at frontend and can create beautiful experiences, animations, etc. But even better:
Explainer videos. The output format I am most bullish on is fully custom / bespoke explainer videos generated on any arbitrary topic. Experiment with things like "Create a 3b1b style video explainer on X. Use my ElevenLabs API key for audio narration". (you'd need an API key for the latter or you can ask your LLM to find you decent free alternatives that use your local compute). This is actually starting to work!
In summary:
- As LLMs get better, they will do more and more of the legwork autonomously, and a lot more of our work will rise up the abstractions into oversight and understanding.
- Luckily, LLMs can help here too because as intelligence and code are increasingly abundant, you can ask for large, custom, discardable software artifacts (e.g. web apps, video explainers) that would have never made sense to create before. Push the boundaries here and you'll be surprised.
Extremely cool -- and Canadian!
1/ The US launched America(.gov) yesterday and it got a bunch of buzz. It's an "AI front door" to 29,000 federal websites.
Canadians can do the same or better! I was curious, so overnight I built Canada.ca 2.0 (with Claude)
Ask in plain English or French, get answers only from federal government pages.
