Mercury Decide
Hosted decision model for classification, scoring and extraction from text and images
Mercury Decide is a closed decision model from Inception: it answers typed questions, such as yes or no, pick one or pick several, with probabilities instead of writing text. It costs $0.02 per million input tokens (Inception API), and output is free. It scores 73.6 on the independent JevBench Capability Score (board v1.7.46), where Jev, the reference, scores 77.1.

Mercury Decide benchmarks
| Benchmark | Result | What it measures | Reported by |
|---|---|---|---|
| JevBench v1.7.46 | 73.6 | Capability Score: accuracy and calibration on typed decisions, with Jev as the reference system | Independent |
| JevBench time | 0.34 s | Seconds per decision: measured end to end for hosted APIs, the board's estimate for self-hosted models | Independent |
Makers' speeds are measured on their own hardware and aren't comparable with each other or with JevBench's timings.
