Harmonic

Building Mathematical Superintelligence

[Harmonic @HarmonicMath]

Many of us intuitively feel that the field of mathematics is going to change, so let's unpack the likely outcomes, without resorting to hyperbole or doomerism.

[Pietro Monticone @PietroMonticone]

@HarmonicMath is hiring a Formal Verification Engineer to develop Aristotle and apply it to formally verify production hardware and software!

The work spans formal methods research, product development and customer deployments.

Join our team in Palo Alto or London!

Today we're launching Miles v0.1, an open-source RL framework for LLMs and multimodal models.

RL training is easy to start and hard to debug. Miles helps you ensure your run is correct, use hardware efficiently, and keep RL running at scale.

Over the past 9 months, 72 contributors have landed 1,326 commits, 85 GPU E2E CI tests, battle-testing Miles on frontier open models like Kimi K3, DeepSeek V4, Qwen 3.8, GLM 5.2, Inkling, MiniMax H3, etc.

Miles powers frontier-model development and production RL workloads at @humansand, @periodiclabs, @modal, @DecagonAI, @Eigent_AI, @nebiusai, @IBM and more, on both @NVIDIAAI and @AIatAMD hardware.

Here is what we built, and why teams picked Miles🧵

Aristotle

[deckard @slimer48484]

I am absolutely stunned by how effective @HarmonicMath is at lean 4 formalization of mathematics. It's able to fill in gaps and understand intent as well as intelligently leave out of scope work axiomatized when automatically formalising math.

🔥Sir Timothy Gowers shares how he used Aristotle to effortlessly autoformalize a complex paper into Lean—without needing to know a single line of Lean himself.

The future of mathematical research is changing fast.

[Timothy Gowers @wtgowers @wtgowers]

Luckily, I had recently been contacted by @PietroMonticone from https://t.co/7UBj0DaQTQ, who asked whether I had any formalization projects I would be interested in undertaking using their Aristotle system. I'm happy to say that it has just successfully formalized our paper.

[Pietro Monticone @PietroMonticone]

A pleasure to help @wtgowers and his colleagues get their preprint formalised with Aristotle (@HarmonicMath).

The long case analysis that a referee would understandably prefer not to check by hand is now formally verified in @LeanProver.

The code should be available on @GitHub before long. After some further cleanup, parts of the supporting API may also be suitable for upstreaming to Mathlib.

AI is accelerating mathematical research in increasingly deep problems

We’re partnering with the @AIMathematics to develop open, human-centric benchmarks for AI in mathematical research

The benchmark is built around 50+ hard problems selected by mathematicians to measure how AI can accelerate discovery, from generating new ideas to tackling some of the field’s most challenging questions

[Harmonic @HarmonicMath]

verified codegen is inevitable

it's the only solution to ubiquitous, cheap, and ever-improving offensive cybersecurity capabilities

[Harmonic @HarmonicMath]

From @emilyriehl on the #aboutlogic podcast (w/ @DenizPhiMa):

"I much prefer to interact with an autoformalisation agent than a large language model in discussing mathematics, because the large language models will feed you a lot of bullshit ..."

"I came up with my own counterexample, and then I asked Harmonic's agent Aristotle to verify it for me in Lean as a kind of extra check that my counterexample was correct. I did not ask a large language model for this, because if they tell me it's correct, that gives me no assurance ..."

"Aristotle was able to confirm that it is a valid counterexample."

[Deniz Sarikaya @DenizPhiMa]

We are very happy that Emily Riehl @emilyriehl joined or little podcast #aboutlogic and talked about higher categories, synthetic mathematics, formalization and much more.

🪄🧙Aristotle is the mathematician's super-assistant

Check out how @LorenzoLuccioli uses Aristotle to develop new results in algebraic combinatorics

[Lorenzo Luccioli @LorenzoLuccioli]

Happy to share that our paper

“Mapping Uncharted Symmetries: Machine Discovery in Combinatorics”

has been accepted to the ICML 2026 AI4Math Workshop.

We study AI for discovery in algebraic combinatorics, with verification in @leanprover using @HarmonicMath’s Aristotle.

The negation of Erdos unit distance conjecture, now formalized by Aristotle

You can try it for free at https://t.co/azsI6J8pPv

[Alex Kontorovich @AlexKontorovich]

Oh and Kim Morrison used Claude + Aristotle + Codex to formalize the negation of the Erdos unit distance conjecture: https://t.co/Y0mPvIm7S1

It's nice to see that this was built on top of PNT+; so despite the fact that we haven't been able to upstream it to Mathlib (the Residue Theorem we have in PNT+ is just for rectangles, and Mathlib will want a much more general version...), it's still useful in other applications!...

JUST IN: Aristotle claims the top spot in lean-eval, the Lean AI formalization leaderboard!

Aristotle is getting stronger and more capable by the day, try it out for your formalization needs.

Formal verification is the future of crypto

[Derek @dhsorens]

We at Protocol Snarkification - me and @alexanderlhicks, plus about 30 or so external collaborators - are working hard with formal verification to ship the highest-assurance zkVMs possible. (see end of thread for collaborators) (1/n)

Fantastic to have Rustan Leino join us at @HarmonicMath to help advance AI ✕ mathematics ✕ verification.
