Laya
Laya is an open-weight decision model from Convai Innovations (Apache 2.0, 421M parameters): it answers typed questions, such as yes or no, pick one or pick several, with probabilities instead of writing text. It's currently free to use (Vercel AI Gateway). It scores 32.5 (self-hosted; seconds are the board's estimate; outside the board's latency cap) on the independent JevBench Capability Score (board v1.7.46), where Jev, the reference, scores 77.1.

Laya benchmarks
| Benchmark | Result | What it measures | Reported by |
|---|---|---|---|
| JevBench v1.7.46 | 32.5 | Capability Score: accuracy and calibration on typed decisions, with Jev as the reference system | Independent |
| JevBench time | 1.80 s | Seconds per decision: measured end to end for hosted APIs, the board's estimate for self-hosted models | Independent |
| Reported speed | 33 ms on a T4 GPU | Latency on the maker's own hardware | Convai Innovations |
Makers' speeds are measured on their own hardware and aren't comparable with each other or with JevBench's timings.
