Frozen evidence · Support urgency v1

Support-urgency benchmark: 600 held-out cases

Correct answers on 600 held-out messages at the 0.5 threshold: Jev 596, Clef 586, Clef Flash 570, Decisions API 597, GPT-6 Luna 598. Every decision model ranks urgent messages above the rest almost perfectly. They differ in where their probabilities sit: the threshold that works best ranges from 0.20 to 0.80, and a threshold chosen for one model costs accuracy on another.

FROZEN EVIDENCE · SUPPORT URGENCY V1

Results across 600 held-out cases

Every model received the same fictional messages and the same question: is this message urgent? Decision models answer with the probability of yes; an answer here is yes when that probability is 0.5 or more. Every attempted case stays in the denominator. Values in parentheses are the 95% interval. The benchmark measures this urgency question only.

Missed urgent: an urgent message answered no. False alarm: a non-urgent message answered yes. Cost is an estimate from the token counts each provider reported for this run at list prices checked October 9, 2026; it is not a bill.

THRESHOLDS

The threshold each model needs

A decision model returns a probability, and the application decides where yes starts. For each model the threshold with the most correct answers on the 200 development cases was chosen, then applied to the 600 test cases. The structured-output baseline returns yes or no without a probability, so it has no threshold to set.

WHERE EACH MODEL WAS WRONG

Errors by kind of message

Wrong answers at the 0.5 threshold out of the test cases of each kind. A message is urgent only when the problem is happening now, stops a task and affects more than one person; the other kinds fail exactly one of those, or describe no problem.

PROBABILITIES

Ranking and calibration

Ranking (AUROC) is the share of urgent and non-urgent pairs in which the urgent message got the higher probability; 1 is a perfect ordering. Calibration error is the gap between the stated probability and how often the message was urgent, across ten bins; 0 is perfect. The Brier score is the mean squared gap; lower is better.

This needs escalating as top priority! Our shop is run by a registered charity — every sale funds a children's reading programme — and I've only just discovered you offer a nonprofit rate while we've been paying the standard price for two years. The shop itself is ticking along nicely, orders in and out every day; I just need to know how to apply for that discount before our annual renewal goes through on the 20th!

Good afternoon, I am writing in the name of our finance department. On the first of next month our company moves its registered seat to a new building, and from this date all supplier invoices must carry the new address to be accepted by our auditors. Your October invoice arrived correctly and is already paid, so with the past documents everything is in order. I would ask you to put the new address on the invoices starting with the November one. I can send the official confirmation from the commercial register if you need it for your files. Please tell me also if this change I can make myself somewhere in the account settings. Thank you and best regards.

We onboard every new hire through your course platform, and today is induction day for the autumn cohort. At nine, twelve new starters sat down in our head office, eight more in the northern branch and five at the lab site, and every one of them clicked 'Begin course' and got a spinning circle followed by 'Something went wrong'. Their managers have been sending me photos of that screen from all three sites for the past two hours; the newest arrived while I was writing this sentence. Nobody has got past the first slide, because nobody has seen a first slide. I logged in as an admin to check and the course preview gives me the same message. Twenty-five people are being paid to stare at an error page. I chose your platform so that I would not have to stand in front of a room and read out policies myself. What is going on?

I teach computer science and my students use your public API for their coursework projects. Since Monday morning the API has been refusing every request with a server error, and not one of my thirty students can get any data back from it. I assumed we had done something wrong, but a teacher at another school and a colleague at the local college both tell me their classes have exactly the same failure. We have wasted two full lessons on this now, which is very frustrating with a project deadline coming. I checked our key and our request limits and both are fine. Having said that, there's no real rush, so please look into it whenever you get a chance. One small unrelated thing: is there a way to get a printable copy of our last invoice for the school office?

Since 8:30 I have been trying to send the appointment reminder campaign for a dental client, and every single text comes back 'undelivered: carrier route error'. That is 1,400 messages queued and zero delivered; I retried a batch of ten five minutes ago and got ten more failures. I rang a friend who runs campaigns at another agency, and she is looking at the same error on her dashboard, as is a retailer she knows who sends through you directly. My client's patients have appointments tomorrow morning and not one of them has been reminded. I have no other channel set up for this account. (For the record, this is nothing like the sender-name mix-up we had last year; that was sorted within a day and has been fine ever since.) I would really like to know what is going on, because 'queued' is all your dashboard will tell me.

Case text is fictional. A missing or invalid answer counts as a disagreement. Filtering runs in your browser and calls no model.

SCOPE

Limitations

  • The messages are fictional and English-only, and half of them are urgent. The results do not estimate how often real support messages are urgent, or performance in other languages and industries.
  • The rule is one definition of urgency. Review it against your own escalation policy before relying on these results.
  • Labels are assigned by rule from each case’s fact sheet and were confirmed by two model read-backs. No human reviewed the cases.
  • Cases that either read-back could not decode were removed, so the hardest phrasings are under-represented, and most models answer nearly every case correctly.
  • Each threshold was chosen on 200 development cases and can shift on other messages.
  • One run at one time cannot establish latency or reliability under production load.
  • Cost figures are list-price estimates from reported token counts, not provider bills.

REPRODUCIBILITY

Methodology and downloads

The result rows hold every model’s recorded answer and probability for all 800 cases, development and test. The manifest records the dataset hash, model revisions and run conditions: one request per case and model, no retries, caching disabled.
