Evidence

Washington Post reporting

The Washington Post reported that an OpenAI model produced solutions to more than 300 open research problems in mathematics, outpacing human researchers over the test window.

"Open problem" spans folkloric conjectures to published hard problems. Source: Frontier model launches.

What it means

The claim has the shape of a frontier milestone — externally checkable, named problems — but proof lives in independent mathematicians re-deriving results, not a Post write-through. Treat vendor talk of "AI mathematicians" as positioning for the next raise.

If even 10% of the solutions survive peer check, this is a genuine step-change in AI-assisted research math — the magnitude is why it earns a slot even at low confidence.

Stat of the Day

per million input tokens — Claude Haiku 5.5

Roughly 75% cheaper to run than Haiku 4.5 on average , and the same price as OpenAI's GPT-6 Luna. Two labs now agree on the small-model floor. Source. Source: Anthropic release, Oct 7 2026; OpenAI GPT-6 Luna rate card.

Today’s Take

Today was two stories, not five: the small-model tier commoditized, and the regulators finally wrote agents into the governance perimeter. Each one in isolation is a buyer-side win — cheaper inference, clearer rules — but together they shorten the window where "experimental agent pilot" is a defensible procurement posture. The next twelve months separate teams that productionized while the floor was moving from teams that waited for stability that is no longer coming. Considered and passed: Manus's $500M round (single CNBC source, no valuation disclosed) and the Meta VP's one-person-unicorn claim (no customer, no number).
