Apodex launches TRACES, a benchmark that evaluates AI on real scientific discovery

Most AI benchmarks test whether a model can recall the right answer. TRACES, introduced today by Apodex, asks a harder question: can an AI system actually investigate a problem it hasn't seen before, form hypotheses, use tools, and arrive at a verifiable solution? The benchmark comes with a technical report on arxiv and a press release backed by multiple outlets, giving it more credibility than the usual "we made a leaderboard" announcement.

Ex-Nvidia AI research VP Fidler raises $90M+ seed for world-model startup

A massive seed round just landed in the world-model space. Veeda, a new startup building world models and led by Sanja Fidler — formerly Nvidia's VP of AI Research — has raised over $90 million in seed funding from Khosla Ventures and Radical Ventures, according to The Logic. World models — systems that learn to simulate how the physical world works — have become one of the hottest frontiers in AI since NVIDIA open-sourced Cosmos 3 earlier this year.

Gowers: LLMs solve math's biggest problems with counterexamples

A Fields Medalist's honest read on the LLM math boom, and a new benchmarking tool that tests models against your own data instead of someone else's. Fields Medalist Timothy Gowers says the most famous mathematics problems LLMs have solved so far came almost all as counterexamples, not proofs. Writing days after OpenAI announced it had cracked ten major open problems — including the first construction of a non-sofic group and a superexponential lower bound for multicolor Ramsey numbers — Gowers…

Anthropic's first profitable quarter rewrites the IPO math

Anthropic told prospective investors it generated more than $11.5 billion in revenue in the second quarter with positive adjusted operating income — its first profitable quarter by that measure. The numbers, from documents viewed by Bloomberg, land weeks before what reporting has described as potentially the largest IPO on record, and they reset the conversation about whether frontier AI can be a real business. The numbers behind the milestone The scale of the jump matters as much as the…

Claude settles every open Hadamard matrix below order 2000

A morning of frontier math and agent reality checks: Claude just closed out every open Hadamard matrix below order 2000, Anthropic published its first deep study of what happens when agents interact at scale, and Qualcomm's $3.9 billion bet on AI software is officially complete. Anthropic mathematician Levent Alpöge and two collaborators used Claude to construct every previously unknown Hadamard matrix below order 2000 — twelve in all, led by the order-668 case that had been the smallest…

Claude lifts Riemann zeta zero bound to 67.2 percent

Anthropic published the most striking AI-math result in weeks, while a Hugging Face–EleutherAI project found a cheap fix for one of open training data's quietest problems — and Hong Kong's biggest broadcaster decided it wants in on the compute buildout. An unreleased research version of Claude improved a long-standing lower bound on the proportion of Riemann zeta zeros that lie on the critical line — from 41.6 percent to 67.2 percent — and produced a formally verifiable proof of the result.

ChatGPT-assisted proof topples the 30-year-old HRT conjecture

Another classic open problem has fallen to an AI-assisted counterexample — this time in harmonic analysis, and with a proof that was, by the authors' own account, painstakingly human-verified afterward. Mathematicians have disproved the Heil–Ramanathan–Topiwala (HRT) conjecture — a 30-year-old open problem about whether a signal's time-frequency shifts can ever cancel each other out — with an explicit counterexample that ChatGPT helped find.
