Small open-weight 4B decision model on Qwen3.5-4B for low-cost text and image decisions

Perplexity Decider Flash V1.2 is an open-weight decision model from Perplexity (Apache 2.0, 4B parameters): it answers typed questions, such as yes or no, pick one or pick several, with probabilities instead of writing text. It costs $0.01 per million input tokens (OpenRouter, Vercel AI Gateway), and output is free. It scores 62.5 (self-hosted; seconds are the board's estimate) on the independent JevBench Capability Score (board v1.7.46), where Jev, the reference, scores 77.1.

## Perplexity Decider Flash V1.2 benchmarks

| Benchmark | Result | What it measures | Reported by |
|---|---|---|---|
| JevBench v1.7.46 | 62.5 | Capability Score: accuracy and calibration on typed decisions, with Jev as the reference system | [Independent](https://benchmarkheaven.com/jev-models) |
| JevBench time | 0.23 s | Seconds per decision: measured end to end for hosted APIs, the board's estimate for self-hosted models | [Independent](https://benchmarkheaven.com/jev-models) |

Makers' speeds are measured on their own hardware and aren't comparable with each other or with JevBench's timings.
