Benchmark-only doubling

The doubling is real on one ruler: Anthropic's internal benchmark index. METR says that ruler covers well-specified tasks, and Anthropic redacted most of the rest.

METR's independent review does estimate about 2x, and rules out a compute surge as the cause.

The reality check

the public number is a benchmark index on well-specified tasks, the checks span 1.1x to 2.9x, and Anthropic redacted most of the evidence METR found most informative.

Why care? Treat "AI doubled AI progress" as a credible estimate from one independent reviewer, measured on benchmarks, with wide error bars. You cannot check most of it yourself; METR says the public has to rely on its judgment.

Take this with youMETR does find Anthropic's progress roughly doubled, but only on a benchmark index of well-specified tasks. Its checks range from 1.1x to 2.9x and most evidence is redacted.

The claim we checked

AI is dramatically accelerating AI research at Anthropic right now, roughly doubling the pace of capabilities progress.

These are quoted receipts, not a count of independent investigations. Several reports may rely on the same original source.

The idea, step by step

What the 2x actually measures

  1. Anthropic says it may soon hit its own 'dramatic acceleration' threshold
  2. METR measures 1.9x, but on benchmark scores for well-specified tasks
  3. The range is 1.1x to 2.9x, and Anthropic redacted most of the key evidence
Next: Nasdaq's $2.5T midterm rout

Nasdaq's $2.5T midterm rout

The $2.5 trillion Nasdaq loss on 5 November is real. Blaming it all on the blue wave crops out a month of AI selling that came first.

the Nasdaq did fall 5.5% on 5 November, and the Guardian puts the market value lost at $2.5 trillion.

The reality check

the Nasdaq 100 had already fallen 6.6% in October on AI earnings and financing worries.

Why care? If you quote this, say the vote triggered Thursday's fall, not the slide. Anyone reading a one-week chart is missing the October losses that set it up.

  1. 5 Nov: Nasdaq down 5.5%, $2.5 trillion in market value

Next: Oracle's older-GPU defence

Oracle's older-GPU defence

Microsoft let its Oracle GPU rental lapse. Oracle answered with a 20% renewal premium from a different batch of capacity, and nobody has said who takes Microsoft's share.

Bloomberg, via Reuters, says Microsoft declined to renew and has been switching capacity off.
