Jev or Laya: how to choose

Updated 24 Sep 2026

Choose a candidate by deployment requirements, then evaluate both on the same labeled workload. A hosted API can simplify a prototype; local inference gives you responsibility for hardware and operations. Neither choice establishes better accuracy for your task.

Start with deployment requirements

Jev’s quickstart describes an authenticated hosted API. The Laya repository documents local inference and an Apache 2.0 license. Check the exact release, model artifact and data handling requirements before implementation.

Compare versions, not brand names

Laya’s benchmark report contains results for multiple versions and configurations. Training and calibration changes matter. An older checkpoint’s result should not be treated as the capability of every later release.

Local GPU timing and hosted API round-trip timing measure different conditions. Treat published comparisons as leads for reproduction, not proof that one model wins your workload.

Run one fair evaluation

1. Choose a representative labeled dataset and keep an untouched test split.
2. Record model version, question text, label definitions, training data and calibration procedure.
3. Measure task accuracy, important error types and the fraction sent to review.
4. Measure end-to-end latency, API charges, compute and review effort under the same load.
5. Choose a threshold using development data; report the final result on the untouched split.

What should a routing comparison include?

Include ambiguous requests, missing context and an other label. Test whether the fallback catches errors, not just whether it runs. The routing policy example provides a small deterministic test, separate from model evaluation.
