Support-routing benchmark: 100 held-out cases

All five models returned a valid label for all 100 cases. With every attempted case in the denominator, operational success was 92% (85–96) for Jev, 92% (85–96) for Clef, 87% (79–92) for Clef Flash, 98% (93–99) for GPT-6 Luna, and 94% (88–97) for the Decisions API. The intervals describe uncertainty in each model's observed rate. This report does not include a paired statistical comparison of the differences between models.

FROZEN EVIDENCE · SUPPORT ROUTING V1

Results across 100 held-out cases

Every model received the same fictional cases and instructions. Accuracy and macro-F1 describe valid responses; coverage shows how often a valid response was returned, and operational success includes every attempted case. Values in parentheses are the 95% interval from the frozen report. The benchmark measures this routing task only.

Probability calibration

ECE uses ten equal-width bins of the chosen-label probability. Multiclass Brier score ranges from 0 to 2; lower is better. Both use only available distributions, which may be an unrepresentative subset. Failed attempts and missing distributions remain in coverage.

Estimated inference cost per 1,000 tickets Estimated

Clef Flash: about $0.027 (mean 297 input tokens × $0.09 per 1M). Input tokens only; the provider reported no output tokens.
Clef: about $0.071 (mean 297 input tokens × $0.24 per 1M). Input tokens only; the provider reported no output tokens.
GPT-6 Luna: about $0.040 (mean 200 input tokens × $0.1 per 1M + mean 40 output tokens × $0.5 per 1M). Input and output tokens.
Decisions API: about $0.025 (mean 249 input tokens × $0.1 per 1M). Input tokens only; the provider reported no output tokens.
Jev: about $0.020 (mean 482 input tokens × $0.042 per 1M). Input tokens only; 57 output tokens per ticket are not priced because the provider lists no output price.

Token counts are provider-reported from the run completed October 9, 2026. List prices were last compared with the providers' pricing pages on October 9, 2026. Providers may change prices at any time, so check them again before relying on these figures. This is not a measured cost and not a ranking: a difference of a few cents per 1,000 tickets does not choose a router.

PER-LABEL EVIDENCE

Where each model was right and wrong

Computed from the published rows. Precision describes the valid answers a model gave for a label. Recall keeps every attempted case of that label in the denominator, so a missing answer counts as a miss. Intervals are 95% Wilson intervals; with about 20 cases per label they are wide.

Clarification requests: `needs_clarification` recall

How often each model sent a held-out request that needed clarification back for clarification instead of routing it to a team. The denominator is every case labeled needs_clarification, including attempts with no valid answer. This slice covers ambiguous or multi-intent support requests; it does not measure general out-of-domain detection. The intervals describe uncertainty in each model's observed rate. This report does not include a paired statistical comparison of the differences between models. These counts describe this task, not a ranking.

Case text is fictional. Provider responses and internal review rationales are not published.

SCOPE

Limitations

The cases are fictional and do not estimate real-world support-intent prevalence.
AI review is disclosed but was not counted toward the two required human reviews.
This task-specific synthetic benchmark does not establish a universally best model.
Latency reflects the disclosed run environment and date, not a service-level guarantee.
Cost is shown only when an immutable pricing snapshot or provider-reported amount is available.
