METR's Anthropic audit explained: AI now speeds up its own R&D ~2x
METR spent 11 weeks inside Anthropic and estimates its models now improve about twice as fast, mostly thanks to AI. Here's what that means and what stays hidden.
In 60 seconds
- METR, an independent evaluator, spent 11 weeks inside Anthropic and judges its models are improving on well-specified tasks about 2x faster than in March 2024–October 2025, with roughly 80% of that guessed to come from AI doing AI research.
- METR fitted a trend break in Anthropic's internal capability index (AECI): about +15 points a year before October 2025, about +29 after (1.9x, 95% CI 1.5–2.8x), then cross-checked it with staff interviews, surveys and training-compute data.
- It matters because Anthropic's own warning threshold for 'dramatically accelerated' AI-driven progress may already be crossed, yet Anthropic redacted most of the evidence METR found most informative.
An independent evaluator has spent eleven weeks inside Anthropic and come back with a number that sounds abstract but is not: the lab's AI models are now improving about twice as fast as they were a year or two ago, and the best guess is that most of that speed-up comes from AI helping to build the next AI. The twist is that the people who did the measuring say you cannot fully check their work, because the company they audited removed most of the evidence they found most informative.
The plain-English version
Imagine a bakery that makes better bread every year. For two years the owners improved the recipe at a steady pace. Then, about a year ago, the improvement rate doubled. Why? Maybe they hired more bakers, bought better ovens, or got lucky. Or maybe the new ovens themselves started suggesting recipe tweaks, so the bakery now improves partly because of its own bread-making machines.
That is the question METR (an independent nonprofit that evaluates frontier AI) set out to answer about Anthropic, the company that makes Claude. From 12 August to 29 October 2026, a small METR team worked inside Anthropic with access to internal data and about 15 staff interviews. They asked three things: has the pace of improvement sped up, how much of that is because AI is helping, and is anything likely to slow it down?

DeepMind says AI agents found two weaknesses in legacy 1024-bit RSA within weeks
Google DeepMind's Pushmeet Kohli announced on 6 November that AI agents, under human supervision, found two advances against legacy 1024-bit RSA, Interesting Engineering reports. One is a signature-forgery technique said to be up to 1,600x faster than previous methods; the other reportedly cuts the average cost of factoring each additional key in a batch by about 30x. The article says modern encryption in use today is unaffected, since 1024-bit keys have largely been replaced. The figures come from DeepMind's own announcement, not independent checks.Why it matters: It is a concrete case of AI helping to weaken a long-trusted cryptographic scheme; anyone still running 1024-bit RSA keys should plan to retire them.

METR: Anthropic's AI capability progress is about twice its earlier pace, mostly AI-driven
In a report published 5 November, the independent evaluator METR estimated that Anthropic's benchmark scores have grown about 1.9x faster since October 2025 (95% interval 1.5–2.8x). It judges, subjectively and with high uncertainty, that about 80% of the October 2026 acceleration is due to AI assistance, and that faster training compute is not the cause. Anthropic redacted a majority of the evidence METR found most informative, so readers must lean on METR's judgment more than is ideal.Why it matters: It is the clearest outside estimate yet that AI is speeding up its own development, and the heavy redactions limit how far anyone can check it.

At least 40 local data-centre curbs pass in US midterms; OpenAI answers with a community compact
At least 40 local laws to curb and scrutinise data-centre construction passed across the US during the midterms, The National reports. On Thursday OpenAI announced a National Community Compact that promises to cover the energy costs of the infrastructure it builds, protect local resources, publish local jobs reports and stop using non-disclosure agreements with public officials, with narrow exceptions. The compact calls data centres "compute campuses".Why it matters: Local opposition is becoming a real limit on AI build-out, and the biggest labs are now changing their pitch to communities.

Google commits $17B to Wyoming data centre powered by 702 MW of fuel cells
On 5 November Google announced a $17 billion investment in its first Wyoming data centre, near Cheyenne. Power comes partly from a 702-megawatt natural-gas fuel-cell development (Bloom Energy fuel cells, with carbon capture planned) under a 20-year take-or-pay power deal with AEP, and Google says it will pay for 100% of the power used at the site. Google also met residents who voiced unease about data-centre growth and is forming a community council, per Yahoo Finance.Why it matters: Hyperscalers are building their own power and promising to carry the costs, a direct response to the local backlash.

AI stocks fall as investors question whether the infrastructure boom can hold its pace
The Neuron's roundup reports AI stocks fell as investors asked whether the infrastructure build-out would keep its expected pace, pointing to governments in New York and Amsterdam tightening data-centre restrictions. The National also links Thursday's AI and tech stock drop to investor reaction to Democratic gains in the midterms. Exact index moves were not verified.Why it matters: A slower build-out would hit chip, power and cloud suppliers and the labs that have committed to large compute bills.
