I can recommend the book telling the full story behind Fermats Last Theorem (by Simon Singh). It’s quite fascinating, and paved with really, _really_ weird characters each chipping in on the final solution.

Also recommend his other books!

Big Bang - history of the understanding of space and the universe

Code book - history of the maths of ciphers

Haven’t read them for years but I’ve been meaning to again

Can someone with more knowledge help me with this silly question in my head? >>Along the way, it wrote 13 million lines of Lean and proved 29,500 intermediate theorems Did a human check the 13 million lines of code? How does QA'ing this type of work works?

A human definitely didn't, but one of the benefits of formal verification is that even if the work done to achieve something is slop-y or excessively verbose, solvers like Lean guarantee that the initial proposition (assuming it was written correctly and in this case was definitely reviewed by humans) is definitively True. This is true across other domains of formal verification outside of math as well

guaranteed, up to lean itself having bugs that are exploited by the LLM :shrug:

There's a wonderful documentary by BBC Horizon with Andrew Wiles from 1996 – highly recommend! I saw it in the 90's and it's a documentary for everyone. It captures the effort, struggle, highs and lows of a 7 year effort working on Fermat's Last Theorem.

Earlier quoted context omitted.

It sounds plausible they spent more, given the output tokens (6 billion of them) would cost $300k at API prices and presumably there will have been many more input tokens than output tokens.

Unlikely, api pricing includes a healthy profit margin (as near as we can tell from the outside) which they wouldn’t charge themselves.

I don't think Anthropic is turning a profit ;)

LLMs are pretty good at slogging through. When will they come up with brilliant breakthroughs like Andrew Wiles?

About two month ago: https://en.wikipedia.org/wiki/Jacobian_conjecture

That’s just a counter example I can check by hand with almost zero background.

Wiles’s proof will remain a mystery to me.

Ooh I never realized FLT and Code book were the same author. Yes, both great!

> a team of agents completed the proof in a little under two weeks, consuming about six billion output tokens from a general-purpose internal research model roughly comparable to Claude Fable 5.1. At $50/M output tokens, this would have cost on the order of $300k (plus a bit for input/prefill tokens) at API rates.

But also achievable on a $150/mo (CAD) Max 5 subscription (I currently have 11.6B tokens in the last 30 days) according to /usage. It doesn’t break down input vs. output tokens as far as I can tell.

~10B tokens a month is pretty typical overall input/output usage from my own experience and other developer accounts I've seen
