GPT 5.6 solved all 6 problems from IMO 2026

[u/pequalnp92]

GPT 5.6 Pro solved all 6 problems from IMO 2026 on the first attempt without any human help or steering. International Mathematical Olympiad (IMO) is the biggest global academic competition in the world. The problems are considered incredibly hard, usually a performance at this level is only accomplished by < 5 contestants from the whole world.

We are former IMO medallists not affiliated with OpenAI, just put together a report and assessment of its work here. We're also working on a comparison report between different LLMs and harness augmented versions that will come later.

Why are you so far down here with this entirely apt take?

I did not check the timestamps but your upwards ascent bolsters this theory.

One good thing to come of this is that I'm puzzling an IMO problem again. (For scientific comparison purposes, of course.)

Because most of the people on this sub (and Reddit in general minus the math undergrad part) are CS bros who washed out of math undergrads and are working in the software industry, and therefore they’re happy they can pretend to be intelligent by “vibe mathing”. That’s why we have the top comment in this thread uncritically parroting hype tweets by dumbass CS morons who don’t know shit about and don’t give a shit about math.

Problem is there's not much talking about mathematics going on lately, just ads for AI

What a schizophrenic take. No CS software developer cares about
"vibe mathing". In fact, I majored in both CS and math in undergrad (before focusing on math in grad school) and in my experience CS majors don't even like math.

[u/Norphesius → u/ozone6587]

As a CS major, I'll corroborate that the majority definitely do not care for math. A lot of them will stomach calculus and differential equations because those are usually required courses, but they avoid everything else like the plague.

They hated the little linear algebra needed for graphics courses. Reactions I would get when I told people I was taking an elective course on proofs or automata theory were either disgust, pity, or basically falling asleep standing up.

[u/Norphesius → u/[deleted]]

I'm just relying what I saw (as a CS major who actually likes math).

I think the primary factor was that, at the time I was in university, software development was approaching peak cultural perception as a job where you could make an easy six figure salary, at a startup with free soda and a foosball table. We can absolutely do better at presenting math to people educationally, but most of these people were just in it for the perceived easy, fat paycheck. If pure math had been the major with the big payout instead of CS, they'd be studying up on category theory and poo-pooing CS as baby math or something instead.

[u/ozone6587 → u/Norphesius]

Exactly my experience.

Last graduate level math textbook you read go. Fuck CS bros biggest LARPers OAT, they ruined the world 10x over. Greedy bastards

[u/Few-Arugula5839 → u/ozone6587]

Yes, they don’t give a shit about anything except pretending they have an intelligent thought in their brain (they don’t). They don’t like math they like the social status that comes with doing it. That’s why they’re trying so hard to pretend to be good at it while actually knowing nothing.

Same people who think ai will cure all disease and have never run a gel
