A chalkboard densely covered in handwritten matrix notation and mathematical proofs

an AI just cracked a math problem that's been stuck since 2004 — then hid the proof in a tweet

Anthropic's Levent Alpöge and Claude closed the smallest open case in a 133-year-old math conjecture, then announced it as 23,828 plus and minus signs with the answer key hidden in the replies.

Microsoft says its AI beat Anthropic's top security model. read the fine print first

the 96% score is real. the 'we beat Mythos' headline is doing a lot more work than the benchmark actually supports.
