Decision-model comparison

Jev vs Laya

The same typed questions, the same inputs. Jev (TypeSafe, paid) runs on OpenRouter's Decisions API. Laya (ConvAI Innovations, open source) runs locally with pip install laya, zero-shot and not fine-tuned. Each answer is marked against the answer we expected.

Task by task

Hardware skews the speed test

Laya ran on a shared 4-vCPU server with no GPU. Laya's published 33 ms is on a T4 GPU. Jev's time includes the network round trip to OpenRouter.

Laya is untuned here

Laya's headline 0.766 accuracy comes from a checkpoint fine-tuned on its own benchmark. Out of the box it scores about 0.36. Fine-tuning it on your own labelled messages is what would close the gap.

How answers are marked

Yes/no counts as correct when the probability of yes lands on the expected side of 0.5. A pick-one counts when the top option matches. A score counts when its rounded level matches. The small sample of tasks shows direction, not a benchmark.
