Many mathematicians and researchers (@wtgowers, @ChrSzegedy, @emilyriehl) have written about the interplay between AI and math.

I wrote a short essay on why we are still underestimating how fast AI math is accelerating:

Reading all those recent beautiful essays by Terry Tao, Kevin Buzzard and @wtgowers, I could not resist, but write up my deeply personal perspective on how I perceive and see things:

Two years ago I argued we needed an autoformalizer.

Now the time has come to formalize all of mathematics.

We need to unite behind a single Mathematics Autoformalization Project that turns all known mathematics into one Lean library.

We are poised to translate all known math into formal code. https://t.co/hj64KYKyxc

Prismriver, a Lean 4 music formalization library - talk at Lean NYC this sun (see https://t.co/odN5uDgIMc), at FARM workshop at ICFP, and a free performance 8/24 evening at IU Indianapolis. we will be playing lean compositions!

I'm incredibly excited to announce the founding of the Mathematical AI safety Institute (MAISI) https://t.co/7h28dBocA6. AI safety needs more foundational theoretical development, and mathematicians have the skills and the mindset to help! MAISI is an independent institute with visiting positions ranging from 1 semester to 2 years. Our goal is to get mathematicians up to speed and working on research directions in AI safety as quickly as possible. There is important work to be done, and there is real progress to be made. YOU can help!

Applications are open now! MAISI is aiming to hire 10-30 mathematicians to join us in the Bay Area by January, and scale up to 30-100 for September 2027. If you're a mathematician interested in channeling your skills toward the most important problem of our time, please apply today! https://t.co/PTWQh0MK3T

We formalized the proof of the 3D Kakeya conjecture in Lean from the Sticky Kakeya theorem.

Together with the unconditional Sticky Kakeya formalization by Nankai University × ByteDance Seed AI4Math, this gives a complete formal proof with no sorry and no project-specific mathematical axiom.

A great example of how AI can help turn frontier mathematics into machine-verified proofs.

50-year old math conjecture solved with Sol Ultra.

Feels like the limit of what you can do is increasingly your ambition and imagination:

[Amaury Hayat @Amaury_Hayat]

For the last few months, we’ve been building a proving agent with the Numina Project. Recently, it found a proof of a conjecture in control theory that I had attempted to prove while a PhD student, and that I had not managed to solve. It had remained open since then (1/15)
