Meanwhile it’s showing large improvements on the sorts of software engineering tasks necessary for recursive self-improvement. EPAH crying, losing hope.

that step change in question?

it's doing the exact same stuff it did before (language tasks), but slightly better

Wow. A Step Change Was Performed. This. Changes. Everything.

Language tasks includes writing code for self-improving AGI. This is not comforting

no, they include writing code for self-improving language machines (LLMs)

seems like a safe bet that they will keep getting better at language tasks. wow, more computer stuff on the computers. Game. Changer.

just for coders because its the only thing SV needs it to be good at and then everything else is just rhlf trained by braindead lib "experts" and safety alignment people. I'm sure it's good at math too.

8.10 USAMO 2026

The USA Mathematical Olympiad (USAMO) is a six-problem, two-day proof-based

competition for high school students. It is the next step of the math olympiad track in the

US after the AIME, which was a popular AI benchmark last year but is now saturated. The 2026 USAMO took place on March 21–22, 2026, after almost all of Mythos’s training data

was collected, and we are confident that there was no contamination.

Because USAMO solutions are proofs rather than short answers, grading can be challenging

and subjective. We follow the MathArena

41 grading methodology, where each proof is

rewritten by a neutral model (Gemini 3.1 Pro) and judged by a panel of 3 frontier models (we

used Gemini 3.1 Pro, Claude Opus 4.6, and Claude Mythos Preview) according to defined

rubrics. The final score is the minimum given by any judge.

Mythos 5 scored 99.8% at medium, high, and xhigh reasoning effort, and 98.3% at low

effort, averaging over 10 attempts per problem. Across all 240 attempts, the only proof that

more than one judge scored below full marks was a low-effort attempt on Problem 6,

where the model itself declined to claim a complete solution and proved a restricted

subcase instead. Average token usage per attempt ranged from roughly 42K at low effort to

100K at xhigh. Under similar settings, Opus 4.8 scored 96.7% and Opus 4.7 scored 69.3%

-----------

an LLM is definitely going to 100% the IMO this year.

Yeah it's also way better than that though since it can solve Erdos problems and shit. Olympiad problems haven't been hard for AI for a while, it just gets penalized for not writing the "proofs" exactly like a precocious ape child would
