zh-decision-bench

First Chinese calibration benchmark for Jev-class models: accuracy, ECE, option order and script robustness.

BenchmarkresearchCC BY 4.0 (dataset)

Overview

zh-decision-bench evaluates System One decision models on Chinese tasks, measuring not just accuracy but whether reported probabilities can be trusted. Noting that public evaluations of Jev-class models were English-only, it provides a CC BY 4.0 dataset on Hugging Face (378 items per the list) and evaluates five models, including Jev, the open NeoHorse-Jev-4B, LAYA multilingual and a Qwen3.5-2B logit probe, with temperature refits and robustness tests for option order and Simplified versus Traditional Chinese.

Findings include: Jev led voice routing (0.960, ECE 0.035), urgency and scam detection (0.952, ECE 0.073) with strong order invariance; NeoHorse-Jev-4B tied Jev on voice routing and won customer-service routing and escalation outright but was weak on urgency; a Qwen logit probe did well on routing but collapsed on binary judgments; and LAYA was fast (24 ms) but needed fixed option order and refit temperature, with 28 percent flips otherwise. A decision guide recommends models per task. Raw predictions for all 2,335 model-questions are included.

How it works

  1. Build a Chinese dataset with routing, urgency, scam and escalation tasks.
  2. Run five models and record probabilities.
  3. Measure accuracy, ECE, option-order and script flips; refit temperatures.
  4. Publish a decision guide and raw predictions.

Strengths

  • Fills a non-English evaluation gap.
  • Measures calibration and robustness, not just accuracy.
  • Open dataset and raw predictions.

Caveats

  • Some task subsets are small (e.g. scam n=21).
  • Results specific to Chinese tasks.

Frequently asked questions

Which model is best for Chinese?

Jev led several tasks; NeoHorse-Jev-4B is the strongest open option and won some outright.

Should I use LLM logit probing for binary judgments?

The benchmark found it collapsed on scam detection, so it advises against it.

Does option order matter?

Yes for some models; LAYA flipped 28 percent of answers without a fixed order.
