I think more and more that @eduede.bsky.social has a crucial point. "Intelligence," "understanding," "writing" — AI is fragmenting these concepts by putting us in a position to see that the phenomena we thought they fused are only *correlated* and can be unbundled.

Text: Saw a talk by Eamon Duede this weekend (citation details below) that argued what academics actually gain from AI, at least philosophically, is an ability to unbundle certain concepts  that have been correlated in practice. (Such as discovery and understanding.)

A hallmark of democratic backsliding is government leaders stealing from taxpayers and using public funds to try to get themselves electoral advantages. Backsliding countries keep the form of elections, but corrupt leaders render them no longer free and fair by putting a state thumb on the scale.

Sparsity is back! Sparsity is everywhere in language, but managing it requires overhead. For the last ~15 years it was faster to just do the dense operation, knowing most of it was useless. That sparse operations work is a huge shift in the "do something clever" vs. "spend more money" tradeoff.

Excited to share our new paper, “What AI Benchmarks Actually Measure: Adapting Convergent and Discriminant Validity to Interrogate Fifty-Six AI Benchmarks,” accepted as an oral at COLM! arxiv.org/pdf/2609.08812
Heatmap of average correlations between model rankings on benchmarks grouped into 11 assigned concepts: four capability concepts (reasoning, knowledge, comprehension, summarization) and seven safety concepts (over-refusal, refusal, safety detection, ethics, bias, privacy, unsafe behavior). Diagonal cells show within-concept correlations, ranging from 0.87 (knowledge) and 0.72 (over-refusal) down to 0.20 (bias) and 0.02 (safety detection). Reasoning, knowledge, and comprehension correlate with each other at 0.69 to 0.78, higher than reasoning's and comprehension's own within-concept values (0.66 and 0.68). Ethics correlates more with knowledge (0.70) than with itself (0.55), and bias correlates more with capability concepts (0.41 to 0.45) than with itself (0.20). Privacy and unsafe behavior correlate negatively with reasoning, knowledge, and comprehension (−0.41 to −0.49). Over-refusal and refusal correlate at −0.42.

The GOP cut funding to the IRS because *audits work* and they fundamentally don't believe rich people should have to play by the rules.
Line chart titled "Revenue per audit," subtitled "In-person audits, 2010-2014." It plots average revenue and average cost per audit by taxpayer income percentile, poorer to richer, from the 0–5th percentile to the top 0.1%. Source: Boning et al. 2023, "A Welfare Analysis of Tax Audits Across the Income Distribution."

Across the bottom half of the income distribution, revenue and cost track closely, both around $3,000–$6,000 per audit. Above the median, revenue pulls ahead of cost: about $10,000 vs. $5,000 near the 90th percentile, and about $17,000 vs. $8,000 at the 95th–99th. At the top, revenue jumps to about $31,000 for the 99–99.9th percentile and about $90,000 for the top 0.1%.

Models like Talkie-1930 sound like voices from the past. If they could reliably speak from specified historical vantage points, researchers might also use them to simulate the past. But how reliable are they? Today we release a benchmark answering that question for English contexts 1831-1930.
Free-text evaluation of answers to character modeling and constrained generation questions. This is just one of several scores Chronologic-EN can produce; we focus on it here because it's both the hardest test and the one most relevant to simulation of the past. Frontier models reach 72%; Talkie-1930 is stronger than several larger competitors, but not at the frontier by this measure. Note that this score has improved ~45% in the last two years, but still falls perceptibly short of ground truth.
